Issue with firmware about s3lcd HOT 11 CLOSED

Yes, I did try the S3LCD_OCT_16M version since it is the only version listed for the T-HMI. According to AliExpress description, the listed memories are PSRAM 8MB, and FLASH 16MB. The demo program that was running on it reports 16 each (PSRAM upgraded before shipping, inaccurate listing, or programming? Unknown). Only the Flash tool reported success, the other methods reported errors - Thonny said header error, and I don't have the esptool logs. On reset after Flash tool, the device started it's (dis)connect looping which continued until I put it back into boot mode or removed it from the computer. After several attempts, I finally gave up and searched for the Espressif generic Micropython, which flashed the first time. Since I finally had a success, I retried yours but still no luck. Device currently has the generic version flashed. If the driver itself was available, I would just drop it and a few fonts onto the device and go from there. I am not very familiar with C and variants nor have any environments (except Arduino, and I don't like it) to try compiling it myself. I'm an old BASIC programmer (mainly self taught - GWBASIC, QBASIC, BetterBASIC, QB64, and others) and am learning (micro)Python through these microcontrollers. I also create personal (offline) webpages incorporating vanilla JavaScript (and used to use VBScript) to store/organise/display information. On my T-display, which is running your older version, I am running a modified version of codemee's ESPWebserver (set up in SoftAP/private network mode, displayed running information using your driver) - not pretty but it works. I did try the Lobo firmware but like yours better; which is why I would really like your driver on the T-HMI. My plans for the T-HMI may be bigger than my current ability but that's what trial and error (and plenty of backups) is for.

https://micropython.org/download/GENERIC_S3/ Links at bottom of page v1.20.0 (2023-04-26) bin file Speed, right now, is not much of an issue. I am just wanting to get things started. Opened your link for st7789s3_mpy. I see the st7789.pyi and the two tft files in the examples folder (probably won't need the button file ... yet). I think I am reasonable sure I can modify the tft_config.py, the data is pretty clear on the T-HMI product/pin assignment image for the dev board. I looked up pyi files, and read that that file is basically an info or reference file (no functional code, which explains all the "...") Looking in all folders, I can't find the st7789s3.mpy file anywhere. bigbuckbunny-320x240.jpg bird seems familiar, and vga1_8x8 appears to be the font I will be using once this is up and running (should give me a nice 40x30 text layout).

from that link, and subfolders, I downloaded: st7789s3.py, tft_config.py, hello.py, and vga1_8x8.py. Using the image from https://github.com/Xinyuan-LilyGO/T-HMI image folder, I modified tft_config.sys. But 3 values were missing: the strobe signals (rd, wr) and the reset pins. Using the schematic, I found and traced the rd and wr lines to pins gpio7 and 8 respectively, but no link could be found for RESET (there is a reset for the display, but I couldn't find a GPIO for it). Note that GPIO8 is listed as the LCD_PCLK in the image. GPIO5 is used in the original tft_config.py for RESET, but this is labelled for the Bat ADC I changed it to 9, which is the only pin I couldn't trace. I modified hello.py, changing only the font. Big Test: the running of hello.py: something is happening but no display activity or error returned.. <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Virus-free.www.avg.com <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

First up: happy to say I finally got the st7789s3.py driver to work. Here is my tft_config.py changes: def config(rotation=0): return st7789.ST7789( Pin(46, Pin.OUT), Pin(45, Pin.OUT), Pin(42, Pin.OUT), Pin(41, Pin.OUT), Pin(40, Pin.OUT), Pin(39, Pin.OUT), Pin(47, Pin.OUT), Pin(48, Pin.OUT), Pin(8, Pin.OUT), Pin(36, Pin.OUT), 320, 240, reset=Pin(37, Pin.OUT), cs=Pin(6, Pin.OUT), dc=Pin(7, Pin.OUT), backlight=Pin(38, Pin.OUT), rotation=rotation) For the RD and RESET, I used unused GPIOs (36 and 37 in this case) since it refused to let me blank those out. In hello.py I added: from machine import Pin tft_power = Pin(10, Pin.OUT) tft_power.value(1) I also commented out the default font and uncommented vga1_8x8 No other changes were made to any of the other files used. Now its hello!-ing all over the place. Next up, I will also be testing out the new THMI pure python driver you wrote. I see the link is on the gethub response page. I am really happy for the help you have given, its made my day (which has been pretty crappy so far - lots of rain, minor traffic accident, no one hurt, almost no damage to vehicles)

T-HMI driver worked perfectly. Only changes anywhere were to the used font in hello.py (changed to vga1_8x8). On Sun, May 28, 2023, 1:58 AM James V. Fields ***@***.***> wrote:
