You could check HAGL which is a lightweight hardware agnostic graphics library. It does not contain any hardware or platform specific code. You can use it with any microcontroller including ESP32 and esp-idf. Being hardware agnostic means user has to provide a HAL. There is a HAL for ESP32 which sup...

Yeah. Also need to support transparent background color with fonts. I have been pondering if there should be separate functions for fonts and sprites. Sprites would act similar to way you described. Custom "player/missile" fonts would be possible for fast mini-games! (Yeah, I grew up with an Atari 8...

If you are looking for library to draw graphical primitives and want to get rid of Arduino stuff check HAGL. It is still work in progress but API should be 80% stable. You need to provide it with HAL which has putpixel function for your e-paper display.

ESP32 is capable of playing 320x240 MJPEG video approximately 8-9 fps. This probably could be tuned up to 12 fps. I made a proof of concept video player which plays RAW RGB565 and MJPEG videos from sd card. You could probably use that as a starting point. It is ESP-IDF but probably could be ported t...

Only thing I am personally missing at the moment is more I2C controllers. I have a hobby project which requires to be able to act as four I2C slave devices.

What are the expected startup times with ESP32 and FreeRTOS. I made a a test program which simply drives GPIO_NUM_12 high. When checking with scope it takes around 690ms for the pin to go high after power has been applied. void app_main() { gpio_pad_select_gpio(GPIO_NUM_12); gpio_set_direction(GPIO_...
