HI, sorry for the slow response. I just committed v1.3.5 of the library which had changes for STM32 F1 & ESP32 to speed things up. Can you try it to check if it works before I try to merge your changes? |
|
Latest update caused it to draw with x positions reversed, I have fixed that in the last commit |
|
Thanks I have merged your changes into v1.3.6. Can you send me a sample program to include in the examples folder please? |

Drawing a color bitmap to the entire screen with drawPixel takes several seconds on an ESP32, this function does the same thing in 250ms (video)
A 16bit 220x176 image stored in contiguous memory would be much too large for most devices, so the function uses uint16_t** to allow for non-contiguous memory
