Hi, thank you for the great work. I am looking for the original example, that is running on the ATOM Display after first startup. I am interested in the PDQ graphicstest part, as it supports for example roundRects. I have a few existing codes, that I would like to run on the ATOM Display, however they are built on the TFT_eSPI library. For my understanding I am able to use TFT_eSPI functions by adding:

#include <LGFX_TFT_eSPI.hpp>
//#include <TFT_eSPI.h>

However I was not successful to get this running, or even compiling. This is why I thought I could understand how to do it, with the original example, that is running on the Atom Display, as I can see that is basically running the TFT_graphicstest_PDQ.ino example.

Thank you for any help or suggestions.

The examples do not match the latest version.
Our firmware uses drawPngFile to show images from LittleFS.
It was removed in this release. Please give a new example how to use it now.

thx.

Hello @lovyan03,

in my M5 application, I depend on long filenames (8.3 filenames are really outdated).

So how can I use e.g. drawPngFile using the SdFat library?

#include <FS.h>  // including this, didn't help
#include <SdFat.h>
#include <M5Unified.h>

SdFat32 sd; // for FAT16/FAT32
..
M5.Display.drawPngFile(sd, "/m5stack.png", 0, 0); 

fails with compilation errors:

...\Documents\Arduino\libraries\M5GFX\src/lgfx/v1/LGFXBase.hpp:888:23: error: cannot declare variable 'file' to be of abstract type 'lgfx::v1::DataWrapperT<SdFat32>'

Hi,
I'm trying to run the analogmeter example and hitting an error for the coreink.

divide by zero error, could this be that the size of the screen is not recognised?

Hi,
I'm quite new to M5Stack and own a CoreS3. Trying to compile with VS Code and Platformio, I get an error exactly as described here: M5Stack Community: Cardputer and drawJpgFile

It looks like being related to issue #72 Question: drawPngFile using SdFat

Are there any ideas on how to solve this?
Any help is greatly appreciated!

I know that QOI is not already a standard, and an IANA type for that new image format is on the way. But it has a great potential especially for small devices.
So, as I have seen, that the LovyanGFX already supports createQoi() in the Qoi branch, I want kindly ask, if it is possible to merge that also to the M5GFX repo. For me M5Unified + M5GFX has alot of pro's on the M5Core2 (and other) M5 plattforms.
At this point, a big thanks to the high-quality contribution of M5GFX and M5Unified.

Hi Lovyan!

I tried to make use of this library because I am particularly interested in using sprites, but I can't get it to work.
I have searched for a similar issue both in this and in m5stack/M5Unified repo but without luck.

I followed examples listed on the official documentation site, but those don't use M5Unified.

My setup

I am using M5Stick C Plus 2 with Platform IO and Arduino framework.
I have added two libraries for working with the device:

[env:m5stick-c]
platform = espressif32
board = m5stick-c
framework = arduino
lib_deps = 
	m5stack/M5GFX@^0.1.15
	m5stack/M5StickCPlus2@^1.0.2

With this setup, when I take some example code like BarGraph.ino it works out of the box, which is great!

The issue

It is when I try to extend the aforementioned example with M5Unified.h / M5StickCPlus2.h is when it goes wrong. The code compiles fine, and the display is initiated and backlit to ~50%, but the screen is completely black, with no output whatsoever.

The only changes I made are:

// on the top
#include <M5Unified.h>
// at beginning of setup()
  M5.begin();
// at beginning of loop()
  M5.update();

What is the proper way to integrate those two libraries? Am I missing something obvious, or can you suggest some troubleshooting steps?

Similar to #69, I have a unit of the M5StickCPlus2 that is not being detected correctly.

Good unit:

[    42][D][M5GFX.cpp:482] _read_panel_id(): [M5GFX] [Autodetect] read cmd:04 = 00528585

Bad unit:

[    40][D][M5GFX.cpp:482] _read_panel_id(): [M5GFX] [Autodetect] read cmd:04 = ffb38181

Patching

When using the M5Stack CoreS3 With IDF 5.1.1 a compile error pops up.

Line 809 of src/lgfx/v1/platforms/esp32/common.cpp is as follows:

 #if (ESP_IDF_VERSION >= ESP_IDF_VERSION_VAL(5, 0, 2) && ESP_IDF_VERSION < ESP_IDF_VERSION_VAL(5, 1, 0))
      (&dev->comd[0])[index].val = cmd_val;
 #else
      (&dev->comd0)[index].val = cmd_val;
 #endif

Which is checking for idf version 5, 0, 2 and higher and lower than 5.1.0. This does not work on
Changing it to

 #if (ESP_IDF_VERSION >= ESP_IDF_VERSION_VAL(5, 0, 2) && ESP_IDF_VERSION <= ESP_IDF_VERSION_VAL(5, 1, 1))
      (&dev->comd[0])[index].val = cmd_val;
 #else
      (&dev->comd0)[index].val = cmd_val;
 #endif

fixes the issue
The &dev->comd[0] is correct here

This is caused by the failure of allocating DMA-capable memory on FlipBuffer::getBuffer()

called from Bus_SPI::writePixels()

I understand that this is due to the limitation of DMA-capable memory size and cannot be completely prevented from occurring due to conflicting with other processes, but I am wondering if there is some kind of countermeasure.

Please take it into consideration.

Plan 1) Reduce the maximum memory size for one copy.

This can reduce the probability of failure. (but not perfect)

Plan 2) Retry with a smaller size when the allocation fails.

This can increase the probability of succeed. (but it still might fail to allocate.)

Plan 3) Skip the drawing process when the allocation fails.

The drawing result may be incomplete, but it can continue other processes.

Plan 4) Throw exception immediately when the allocation fails.

This doesn't solve anything, but it makes it easier to figure out the reason for the reboot.

Hi, I would like to know if there is a way to duplicate the same image that shows on the M5StickC PLUS screen to LCD Screen Unit 1.14

Your skills with embedded graphics are unmatched.
I was very impressed with the ESP32_ScreenShotReceiver you wrote - expertly avoiding the tight memory limits, and making an incredibly fast real-time windows/ESP32 combined image encoding/decoding system!

Then today I saw your M5GFX library with Jpg drawing! Amazing!

Sorry this isn't an "Issue" - GitHub doesn't have a "Praise" tab.

Hi All,

I have defined two I2Cs in ESP32 to control M5UnitLCD.
Now there is a problem, when i use I2C1 to control LCD everything works fine, but when i switch to I2C2, I2C error occurs, and i use gpio 15/16 or 32/33 to control I2C1 without problem, but I2C2 LCD has problems , can anyone help?

I've written an app on the coreink using M5GFX that displays data on the screen.

Sometimes if i press te powerbutton or wakeup from sleep the black pixels go briefly dark and display the same data a bit dimmer.

It seems the refresh process sometimes behaves oddly with some weird result.
Sometimes during the last step in the refresh process the contents of the display gets a bit dimmer. ( see picture)
I tried the 4 different edp modes but all with the same endresults (sometimes good sometimes dim)

What could be the problem?
Do i need to disable M5 eink when using M5GFX like this :

 M5.begin(false , true , true);

or shouldnt it matter?

            display.begin();
            display.setEpdMode(epd_mode_t::epd_fastest);
              
            display.startWrite();
            display.fillScreen(TFT_WHITE);
            display.setTextColor(TFT_BLACK);
            
            display.setFont(&fonts::FreeMonoBold18pt7b);
            display.drawString(ipStr, 1,10);
            
            char batStr[32] = { '\0' }; // initialize with all zeroes
            sprintf(batStr,"B:%.3fV" ,getBatVoltage() ); 
            display.drawString(batStr, 5,50);
          
            char counterStr[32] = { '\0' }; // initialize with all zeroes
            sprintf(counterStr,"%05d" , esp_random() % 99999 ); 
            display.setFont(&fonts::DejaVu56);
            display.drawString(counterStr, 5,100);
          
            display.setFont(&fonts::FreeMonoBold12pt7b);
            display.drawString("Rain & cloudy", 5,170);
            
            display.endWrite();
            delay(250);   // Give Serial.print statements time to show stuff in monitor
            M5.shutdown(120);

Hi, and thanks for the awesome library !

~/Arduino/libraries/M5GFX/src/lgfx/v1/platforms/esp32/common.cpp:741:16: 
  error: 'class TwoWire' has no member named 'end'; did you mean 'read'?
       twowire->end();
                ^~~
                read

So, this is the situation.
I have two M5AtomDisplay Units, say A and B and I have a wave share 5 inch HDMI display (https://www.waveshare.com/wiki/5inch_HDMI_LCD#Screen_orientation_settings).

Unit A is out of the box plugged to my Waveshare screen. It rins smoothly the graphics. To clarify, I have not uploaded any software to the M5Atom.

Unit B I uploaded the software (Atomdisplay_factory) to the M5Atom. I use Arduino IDE, I dont see any related libs to be updated. BUT, nog graphics shown on the screen. I tried different setting for M5AtomDisplay display. Btw, I know the software is running in the sense that I created a Serial.println(mills()) in the main loop. And I see the loop is running. It is just That nothing is shown on the display.

Anyone any clue how to get this Waveshare working with M5AtomDisplay. Oh, btw, unit B works perfectly with the Waveshare 7 inch display. Help is appreciated.

on my M5Dial,

Using LittleFS,
Suddenly this error occurs.

.pio/libdeps/esp32/M5GFX/src/lgfx/v1/LGFXBase.hpp:920:23: error: cannot declare variable 'file' to be of abstract type 'lgfx::v1::DataWrapperT<fs::LittleFSFS>'
before then, this program normally runs.

how can I use fillRoundRect (x,x,x,x,x) (like in tft_espi, in M5GFX ?
if I write, no error on compile, but also no result in display drawing

Hi!

I wrote a simple sketch using the function mentioned in the comments in drawImageData.ino, display.drawJpgUrl().
The included libraries/files:

#include <Arduino.h>
#include <WiFiMulti.h>
#include <M5GFX.h>
M5GFX display;
WiFiMulti WiFiMulti;
WiFiClient client;
extern const uint8_t jpg[];
void setup(){...............................

The compiler stops and tells me:

F:\sarah\Documents\Arduino\sketches\M5Stack\netStreamVersions\G5GFXVersion\G5GFXVersion.ino: In function 'void loop()':
G5GFXVersion:27:11: error: 'using M5GFX = class m5gfx::M5GFX {aka class m5gfx::M5GFX}' has no member named 'drawJpgUrl'
display.drawJpgUrl("http://untamed.zone/M5Stack/", 0, 0);
^

I don't know if the M5GFX\src\lgfx\v1\lgfx_filesystem_support needs including by-hand, or if it should be ok just using :
#include <M5GFX.h>
M5GFX display;

I have an application that works fine when using Core2 V1.0 with the Display Module 13.2, but when I use the new Core2 V1.1, the display is blank.

M5.getDisplayIndex(m5gfx::board_M5ModuleDisplay) returns 1 on a Core2 V1.0, but returns -1 on a Core2 V1.1, so it appears the Core isn't seeing the display module.

I try to build M5GFX on Ubuntu 22.04 , framework ESP-IDF v5.1 device target esp32s3 but the build crash .
M5Stack CoreS3 is a supported device on framework ESP-IDF ?

Thanks !

I appreciate that the read.me suggests that there are several devices that this library can be used with but wanted to check before I experiment with my m5core2 as I don't want to brick it!

Any advice pls? Thanks.

readPixelRGB does not work in M5Stack CoreS3.

Recently got a number of these displays link but cannot get them to work with the M5Stack AtomDisplay though I do see some artefacts displayed on the screen when I run some test code with Arduino IDE. I know that they are 60Hz with a pixel clock of 66280000. I can drive them with other HDMI sources such as my development Mac, embedded computers etc but not with the AtomDisplay. I'm not a display kinda guy, I write industrial control and state machine code :-). Just wondering if these will work with the AtomDisplay and if so, any pointers to getting them to work? Really appreciate any help + apologies if this is not the right place to post this question.

I'm using the AtomDisplay with PSRAM though I know this makes no difference so the controller is an ESP32 PICO-V3

I'll share my experience.
I encountered an error when trying to run the LongTextScroll.ino sample code for M5GFX on M5CORE2.
The conflict error occurs at the bottom of M5GFX.h, specifically at the line:

cpp
Copy code
using EncodeRange = lgfx::EncodeRange;
I'm writing the code using VScode+PIO.
Interestingly, I don't get this error when using M5GFX in my custom code.
Moreover, the LongTextScroll.ino works fine on M5Stack Basic.

(JP)
わたしの体験を共有します。
M5GFXのサンプルコードLongTextScroll.inoをM5CORE2で動かそうとしたときのエラーについて。
M5GFX.hの一番したのほうの、

でconflict errorが出てしまいます。

自作コードでM5GFXを使っているとこのエラーは出ません。
また、M5Stack BasicではLongTextScroll.inoは普通に動きます。

miniz is vendor'd into this repo, causing duplicate symbol linker errors if M5GFX is used in projects that already use miniz.

Not sure on the best way to handle this. Here are some options:

• Compile time flag that skips compiling miniz.c (assumes symbols will come from somewhere else)
• Rename symbols in miniz.c so they don't conflict with other projects using miniz

I'm running into this specifically in an esp-idf project where I have a miniz component already.

I was trying to implement CI to ensure the component compiles for the various versions of ESP-IDF.

The problem is that the project is not set up in a way that allows for this:
ESP-IDF components should be in a subfolder (commonly main/, but it could also be M5GFX/). Without this, any attempt to compile the component with idf.py build leads to this error:

Called idf_component_register from a non-component directory.

Reference build: https://github.com/KenVanHoeylandt/M5GFX/actions/runs/8222729252/job/22484559726

.github/workflows/build.yml example:

name: Build
on: [push]
jobs:
  build-esp-idf-4.4:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout repo

        with:
          submodules: recursive

        with:
          esp_idf_version: v4.4
          target: esp32

To allow for idf.py build to work independently in this project, these steps are required:

• Add a subfolder for this component (main/ or M5GFX/), move relevant files into this folder and add a CMakeLists.txt
• Add include($ENV{IDF_PATH}/tools/cmake/project.cmake) to the root CMakeLists.txt

Considering that moving source files has a big impact on your currently unmerged branches, I figured I'd open this issue to discuss the proposed changes.

How to use M5GFX on GC9A01 on ESP32C3?
Thank you.

Hi and thanks for this awesome driver!

According to the data sheet of my display, I came up with this configuration. However the initialization fails with an "out of range" error printed in the console.

M5AtomDisplay display( 800, 480, 66, 800, 480, 1, 1, 32000000 );

I plugged the display to a linux machine and extracted the xrandr information after it was detected.

It turns out this display only has one refresh rate: 66Hz (negociated at 65.681445).

I've double checked the numbers in a pixel clock calculator, and the EDID information matches the data sheet information, what am I doing wrong?

On my two M5StickC-PLUS2, I get the following error:

[176344][W][common.cpp:1400] readBytes(): [LGFX] i2c read error : read timeout

It happens randomly.

It seems to happen only when using the IMU.

When it happens, my single (user) task hangs, but the BLE task remains active.

Hi Lovyan03,

I am using M5 ATOM Display and I want to use 16bit RGB565 colors.
I have used display.setColorDepth(16); in the setup after display.init();
However the 16bit colors (for example: 0xCFFC) are interpreted as 32bit colors (0x00CFFC).
