PICNIC problem. Problem-in-chair-not-in-circuit. Forgot to tie grounds together. Works great now. Thanks.
ah. Perhaps I need to drive the signals to +/-10v using a Max232?
Just received my Razor and am having some trouble getting serial comms to work. I have my Razor connected directly to a USB-Serial Cable with port Settings: 38400-8-N-1. Each time I reset the device, I get the same string of garbage characters. I’ve tried different bauds (all the way from 2400 to 115200) and all different parities (Eve, Odd, None, Space, Mark), but still no luck. I’ve tried on both Ubuntu Linux and WinXP and with two different USB-Serial cables and still get the same string of bad characters. Any suggestions? Thanks in advance.
No public wish lists :(
