Not sure how else to post this, so I hope this isn't too off-topic. Let's assume that I'm designing a new board (or two) based on an ESP32 module. I have one of the WROOM devboards - but the new design will likely use an S3 when they drop.

Assuming there are enough free GPIOs left, is parallel preferable over SPI? (I'm only enough to remember the days that we thought parallel was the Dog's Danglers and Serial was consigned to telephones. (Data skew? What's that?! Electrons will never travel that fast and IBM PCs will never penetrate the home!)

So yeah, serial has a place - but I'm curious, is there any particular reason to use SPI over parallel on a new design (one that I can just drop a TFT into?)

My only experience is with the Arduino framework and that largely insulates us from the nitty-gritty but this needs I2S and some serious beef so short of going full SBC with all the uses they come with, I figured the ESP32 is perfect.

I bought the ST7789 parallel port 8-bit screen on Taobao or AliExpress, and it was successfully lit.

This is my attempt on ESP32S2

My code comes from the official warehouse of Espressif which supports ST7789. I believe yours should also support it. I hope you can transplant it.

Thank you for working on such an important project,
I am very new to displays and ESP-32, Could you please help me to connect my display and run a simple test

Thank you so much

@nopnop2002 Hi, are there plans for ESP32S3 support?

I'm new at using the idf.py commands, i always use de GUI options from VSC through ESP-IDF extension, i want to use all functions to create a nice GUI but how can i add the config to menuconfig ?

Enviroment

• Development Kit: ESP32-DevKitC
• Kit version: v4
• Module or chip used: ESP32-WROOM-32D
• IDF version: ESP-IDF v4.1 5ef1b3900
• Build System: CMake
• Operating System: Windows 10 Pro 19042.746
• Power Supply: USB

Problem Description

On 3.5inch Arduino Display-UNO, the color 0xFFFF appears to be mint green.

• The screen uses ILI9486 driver.
• Default Pin configuration

First of all I wanted to thank you for your work.

I have a question.

I have a open smart 3.5 tft display with this setup.

(Screen pins-> ESP32 pins)
D0 -> 12
D1 -> 13
D2 -> 26
D3 -> 25
D4 -> 17
D5 -> 19
D6 -> 27
D7 -> 14
RD -> 2
WR -> 4
RS -> 15
CS -> 33
RESET -> 32

Which are the correct pins on each parameter for this to work? Especially the parameter adc_yp and adc_xm

Can you tell me how to display gif on tft screen?

@nopnop2002 Hello, I wonder if you have any plans for R61529 support?

I am a novice and want to use LVGL, but I don't know how to use it together. Hope to add some clarification

Error compiling i2s_lcd.c, when setting target to esp32.
Because esp32s2 has only one I2S, and the register and esp32 have changes, such as the lack of pdm_conf

i got a tft lcd ili9320
and Wemos D1 ESP32, i have changed RS CS RST pins from 35,34,36 to 15,33,32
menuconfig select 9320, but is doesn't work, always white.
Is it not suitable for OPEN-SMART Products? should i giveup to use another lcd or any recommend driver type?

Can i use for the usb camera live streaming on 8 bit parallel line interface ili9486 lcd
which function will be use for the live streaming of this library ?

You can't tell at a glance if your TFT has a 4-wire resistor touchscreen feature.

An easy way to find the 4-wire resistance touchscreen feature is to perform this sketch using UNO.

I found in your code that it seems to support 16-bit parallel port. How do I start it?

I made some official efforts but failed on 16-bit parallel

espressif/esp-iot-solution#122

When can I see this item in the Component Manager registry?

pio run -t menuconfig

board_build.partitions = partitions_example.csv

According to the documentation

https://docs.platformio.org/en/latest/platforms/espressif32.html#embedding-binary-data

When using driver ili9806 just change ???

I using i2s 16 bit parallel
