Thanks for your response. I finally came to thank conclusion too. I'm now trying to adapt this project for ESP32: https://github.com/bitbank2/PNGenc It seems to work with some quirks but I...

It 's close to #28 but not the same.

Some "appealing" sounds found by bytebanging the registers void poink(){ NR10_REG = 0x15; NR11_REG = 0x96; NR12_REG = 0x73; NR13_REG = 0xBB; NR14_REG = 0x85; } void jump(){ NR10_REG =...

Great like you propose !

I however do not see any obvious issue in void createHistogram() apart that I do not found what bitsSetLUT does (I think a sum of the bits into the byte...

Oh, got it, Histogram is declared as uint8_t, there may be an overflow somewhere and it should be uin16_t for sum of pixel values. I wonder how it could work...

Oh, and indicate which image is printed during batch printing to know the approximate remaining time (or directly the time)
