ImportError: no module named 'tft_config'

[yaconsult]

I have a TTGO T-Display board that was recently purchased. I am not new to python but I am completely new to micropython and esp32. The demo program that comes flashed on the device worked as it should so the hardware is good.

I flashed the following image using 'esptool --chip esp32 write_flash -z 0x1000 firmware.bin' https://github.com/russhughes/st7789_mpy/blob/master/firmware/T-DISPLAY-ESP32/firmware.bin esptool.py v3.1 Serial port /dev/ttyACM0 Connecting.... Chip is ESP32-D0WDQ6-V3 (revision 3) Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None Crystal is 40MHz MAC: 78:21:84:88:c6:dc Uploading stub... Running stub...

I cannot get any of the example programs to work but I don't know what else I might need to do besides flash the firmware.bin file.

I tried entering the st7789_mpy/examples/hello.py from the python prompt after connecting with minicomm and this is the first error that I get:

import random import utime import st7789 import tft_config Traceback (most recent call last): File "", line 1, in ImportError: no module named 'tft_config' import vga1_bold_16x32 as font

Am I missing some libraries or something that I need to copy to the T-Display? Where is tft_config defined? Or are the examples out of sync with the code?

I didn't get that far, but I assume that I will need to copy the font files and maybe some utilities to the board, or are they all frozen/included? It looks like I can copy anything needed with ampy.

Thanks!

Most of the modules for the examples are frozen in the firmware but you need to copy the tft_config.py file from examples/configs/tdisplay_esp32/tft_config.py to your device.

It works and is very fast writing to the display. What a wonderful project you have here for experimenting and learning about micropython and the t-display board! It's a great dev board that is much more fun than blinking a damned LED on the esp32 without a display! LOL

How would a beginner know which files need to be copied to the device? I presume that the fonts need to be copied to it for some of the other demo programs or are they frozen in the firmware? Or is the config file the only one needed because it's the only one specific to the board?

Oh, I see there are some others in the configs folder, like I needed the one for buttons for the roids program - cool! And I found the configs/README that would have told me all this! sigh... It looks like you can "install" a script on the board by renaming it to main.py and putting it on the t-display board so it will run after reset.

Thanks again for a really great and educational repo!

You're welcome. I need to work on the documentation for the examples to clarify the tft_config.py files. I grew tired of editing the examples when testing different displays, so I moved the display config into a separate file for each device.
