| | Expansion board test routine
|
| Hello all, Well here it is, for what it's worth. The functions are pretty obvious, it works just like the original hbtest.c that Fred wrote. To try servos other than #5, you'll have to edit the line: servo5=(16*knob()); In the test_servo() routine. (...) (26 years ago, 15-Feb-99, to lugnet.robotics.handyboard)
