Hi,

Great library, it works smoothly with my ESP32 and my TFT screen.

I noticed that the data variable is undefined on this line:

Maybe the function defintion should be:

def _readblock(self, x0, y0, x1, y1, data=None):

If that's the case and if this repo is not dead, I can make a PR.

Cheers! Thanks for your work

I tried to run the m5stack example on an m5stack core. Using rotation=0 shows the text from right to left. Also width and height are reversed. rotation= 6 shows the text in the upper left corner from left to right, as expected, but width and height are reversed (I set w=320 and h=240, but i need to set w=240 and h=320 to get it right)

Thank you

Hi Jeff, I've noticed some of the settings in the ili934xnew.py module are mixed up, here are my findings.

Test platform: M5Go

Width and height are mixed up and opposite of what's expected

The rotations are mapped oddly too:
r=0 mirrored 0 degrees
r=1 mirrored 90 degrees
r=2 mirrored 180 degrees
r=3 mirrored 270 degrees
r=4 normal 180 degrees
r=5 normal 270 degrees
r=6 normal 0 degrees
r=7 normal 90 degrees

Hope this is helpful information for you.

I got your code working on a TTGO T8 v1.7
It took me a while to figure out which pins to use, so I am posting here the init sequence in case this saves time to other people

spi = SPI(2, baudrate=40000000, miso=Pin(19), mosi=Pin(23), sck=Pin(18))
display = ILI9341(pi, cs=Pin(5), dc=Pin(0), rst=Pin(4), w=320, h=240, r=3)

Thanks!

Hi,
i try to load a raw image (60x60 pixels, rgb565) using the following code:

from machine import Pin, SPI
from ili934xnew import *
import tt24 as font
from framebuf import *

spi = SPI(1, baudrate=45000000)
d = ILI9341(spi, Pin('X5'), Pin('X4'), Pin('X3'),w=320,h=240,r=2)

bg=color565(100,100,100)
fg=color565(0,0,0)
d.set_color(fg,bg)
d.erase()

with open('prism.raw', 'rb') as fp:
    b = FrameBuffer(bytearray(fp.read()),60,60,framebuf.RGB565)
    d.blit(b, 30,30,120,120)

and get this error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "ili934xnew.py", line 247, in blit
IndexError: bytearray index out of range

is it my fault or some issue in the blit source?

This program has had numerous improvements over the last three years thanks to input from a number of users.

I'm baffled as to why you include get_width() in the font file. In my work this function lives in the display driver. The use of a modified version has caused confusion in the forum. Might I suggest you reconsider this decision?

If there is a technical reason for including this method, I will consider updating my format to include it.

Hello,

I'm new to the LCDs IoT, and struggling with few touch screens for a project.
I'm unable to understand if that is currently implemented, from what I read in the ili9341xnew.py

I have two questions:

1. Is the current driver supporting touch screens?
2. Is the current driver providing support for writing images to the Framebuffer? (I don't understand where that library comes from)

Thank you for your help and support with this!
