Hello, Would you please consider requiring a checksum, or at least a duplicate byte, for critical commands? For example, if a bit flip causes the 'change I2C address' command to...
Having a multi coloured display is a real bonus, I can use it to indicate errors and the like. But if I flash/change colours a few times that's a couple...
More than 32 characters crashes the display. I've not had a chance to investigate further but it is consistent. This is a problem for those of us doing DMA writes...
