Re: ESP32 TFT display library

Hi @Vader As far as I know, the library supports only 24-bit BMPs, so BMP with alpha-channel will be ignored: memcpy(&wtemp, buf+28, 2); // the number of bits per pixel if (wtemp != 24) {err=-8; goto exit;} It's interesting to hear from @loboris about plans on image transparency. To put ILI9488 ...

Re: ESP32 TFT display library

I tested under latest esp-idf version with TFT ST7735 and it works fine. I added an issue to report minor changes on https://github.com/loboris/ESP32_TFT_library to compile with c++ projects. Thank you.

Re: ESP32 TFT display library

loboris,
the library does not print text by TFT_print() in esp-idf commits 845c3fb (22 sep 2017) and 050ae50 (08 sep 2017). Also there are some artefacts on screen. It looks like DMA transfer does not work correctly.

The esp-idf commit with which the library works fine is 5539bfb (07 aug 2017)
