Trouble shoot this with just the Robostix (disconnect the Connex and serial adapter). Check that the jumper on the Robostix is in place. Power up the Robostix and measure the voltage between pins 1-3 at the Gumstix header. Also measure between the outer 2 rows of pins on the Port-C header. Regards, Ken |
