pololu ssc in roborealm
« on: December 21, 2008, 08:58:36 PM »
Ok, i have the serial 8 servo controller by pololu, its hooked up to my computer via a usb adapter, its powered with a 6v powersupply, its set on mini ssc mode. Im using roborealm, attempting to do a sciencefair with blob tracking, i have the cog-x and cog-y values of the blob. I have my controller set to move the servos in accordance with those values, but even tho the software shows that the servo is moving, nothing happens out in the real world, the green light doesnt turn on, and the orange warning light stays on, what are the possible problems? im using baud rate of 9600, and COM1

does that controller do anything if you send raw data to it (outside robo realm) ?

Check all the pin voltages with a multimeter. Check battery.

See if a servo pulse is coming out the servo pin using the frequency setting.

Verify you have baud set properly everywhere.

Do a loop back test on the UART (see my UART tutorial).

well, try controlling the servo controller using the received software, or check the manual (i think it works as a virtual serial port) to see what commands it should receive.
as admin says, make sure all connections are right, nothing is reversed or mirrored, etc.
