I try to read or update the color map from a NXT to my NXTCam-V2 (to do a program which can adapt color with the lightness).
The user manual said :
If you need to read Colormap data from NXTCam engine, then follow this:
Run command ‘G’
Read registers 0x80 – 0xAF.
If you need to write Colormap data to NXTCam engine, then follow this:
Write your color map data in registers 0x80 – 0xAF,
Run command ‘S’
I don't know how write that. As anyone an example ? Have I to know I2C?
