Trackball Serial Communication

20 August 2012 - 06:35 PM

Ok, so I have a 5byte serial trackball attached through a level converter to my netduino on port 2. The trackball is hard wired for 1200 baud. I seem to be getting dropped bits. For example Hyperterminal on my pc shows: Left click: 131 -> 10000011 Right click: 134 -> 10000110 Debug output from the netduino shows: Left click: 62 -> 111110 Right click: 158 -> 10011110 Is 1200 baud too slow? Do I have messy edges on my serial and need to pull them up or down? Help!
