Parts:
- cheap "bluepill" STM32 ($1.50)
- 160x128 ST7735 LCD ($2.60)
- SD card

Comments:
- SD uses faster STM32 SPI1 interface which supports 36 Mbps
- SPI1 is shared between LCD and SD card
- Not all SD cards work at 36Mbps
- Fast card at 36Mbps gives 41fps for 160x128 video
- SdFat library uses DMA for SPI transfer
- Big buffer in RAM is used to speed up SPI/DMA transfer
- Requires SdFat, Arduino_ST7735_STM and RREFont libraries and stm32duino
- If you don't want to play with IDEs bin ready to flash is available too
- Use ffmpeg to convert any video, example syntax:
"ffmpeg.exe -i "food.mp4" -an -filter:v:0 "crop=900:720:190:0" -s 160x128 -f rawvideo -pix_fmt rgb565le -y food160.raw"
