I’ve managed to write a fairly complete library to interface with the µVGA-II. One issue I seem to be having is communicating with the device at any speed above 115200 baud.
I’ve managed to do the baud-switch from the initial 9600 baud to start communication, but if I select either of the two possible higher modes 128000 or 256000, communication fails. Looking at the responses back from the device, I occasionally get a NAK (bad input, message not recieved) among a mess of fairly random extra data which makes it look like some sort of synchronization issue. I’m fairly sure I’m not near hitting the peak of serial com speed. I also understand that it could be more of an issue with the module, vs. the dev hardware, but I figured I’d ask you guys.
Have any ideas?
