Topic: bitmap on 2.8" TFT touchscreen using memory alone (Read 715 times) previous topic - next topic

I am using a mega 2560 with the 2.8" TFT touchscreen available on ADAFRUIT. I have 200,000 bytes left on the processor memory. Can I use this to display a bitmap image without using a scan disc card? If so how?

Thanks

Well sort of. Store the array in program memory and pull it out and place it in the display buffer.
However, setting up the array will require a lot statements as each byte has to be defined individually. You are best writing a Processing sketch that will generate those statements for you.
