Developing with the BPI-Centi-S3

Development Platforms
41

Personally, I don’t like having to edit library files. I therefore use the approach described in the Readme of the TFT_eSPI library and prefer to define the pins in platformio.ini. This way, the settings for the project are retained and are not deleted or overwritten if the library changes.

Hi Boris, I tried using tft_espi with the platformio.ini definitions that you sent. nothing displayed on screen… Any idea? I am using v2.5.43…

Is there any relation to the following warning:
Compiling .pio\build\bpi_centi_s3\FrameworkArduino\esp32-hal-timer.c.o

Also tried to execute the “julia-example” from Examples/Generic/Julia_Set and nothing was displayed…

Ok, rewind your platformio.ini back to minimal:

[env:bpi_centi_s3]
platform = espressif32
board = bpi_centi_s3
framework = arduino
monitor_speed = 115200
lib_deps = 
  https://github.com/Bodmer/TFT_eSPI

Copy this User_Setup.h into the TFT_eSPI folder (.pio/libdeps/bpi_centi_s3/TFT_eSPI)

46

Nothing :frowning:
Blank screen.
Maybe it relates to the error I reported earlier during commpile?
warning: “RGB_BRIGHTNESS” redefined

47

The warning can be ignored. It is not relevant here.

I have uploaded my working project to GitHub:

You need to copy the User_Setup.h to the TFT_eSPI library folder.
You may have to reset the board manually after uploading.

Hi Boris, your project now works. When first compiling and uploading, it did not work. I pushed reset and it did not work. Pushed it second time and it works. Really a strange behavior…
In my real project I am using the LilyGo T-Display-S3 (which also comes in a nice box) and it is much better in support and in behaving nicely.
I wanted to use the Centi becuase it uses the same MCU and screen size, but it adds the encoder and buzzer which should be really useful.
Will continue testing.
Thanks a lot for your help!
