Flashing this chip is typically done via an tool, such as a CH341A programmer or a dedicated RT809F. The process is as follows:
, a common universal LCD controller board, its green PCB etched with a labyrinth of copper traces. To most, it was a cheap component for DIY monitors. To Elias, it was a vessel.
Use an image editor to convert your logo to a strict format (usually 8-bit BMP or raw data, limited to small resolutions like 320x240 to fit inside the small flash memory).
