Can anyone help with this?
I am trying to read the colour of a pixel over SPI - i.e. implement a read_pixel() function
Having looked at the datasheet it states that COLMOD should be 0x66 for read operation, that's 18 bits per pixel
I assume it is going to return 3 bytes of data for pixel colour?
Datasheet states "Dummy" after command RAMRD - huh? what does that mean?
When I follow the COLMOD command & 0x66 data byte with a RAMRD command - do I then just SEND 4 bytes of data to clock in 4 bytes? and ignore the first byte back?
I just don't understand the datasheet for RAMRD command
Anyone used this before?
My display works fine but so far not attempted to read anything just write to it
Any help much appreciated
