I got my Bittle assembled and seemingly connected properly, but when I enter calibration mode using the remote, all the servos firm up except for the left elbow which is allowing manual rotation. I can’t get that joint to move with any keypad buttons. I’m not sure how to find out whether there’s a hardware problem requiring a new board or if it’s a software configuration. I’ve tried running the servo tests from the IDE, and I can’t get that one servo it to activate, but I don’t get any error messages saying there’s something wrong. Any ideas? Further troubleshooting steps?
Update: going through the calibration routine in WriteInstinct, I'm not getting any activity for the FL Elbow. I was looking through the OpenCat.h file which the docs suggest has the PWM info for the servo mapping, but it just wasn't clear. I was thinking I could move the PWM to another header and redefine the mapping, but I'm just missing something in the code to make this move.
Hi, were you ever able to resolve this issue? I ran into the same problem. I swapped the PWM headers. my array now looks like this:
byte pwm_pin[] = {12, 11, 4, 3, 15, 10, 5, 2, 14, 9, 6, 1, 13, 8, 7, 0 };It solved the soft-servo problem. But during skill execution, the left-elbow does not seem to be receiving any commands. It remains in the same position the whole time. I wonder if @Plugh was correct when he asked:
"Do I have to remap it everywhere in the instincts and movements."
@Rongzhong Li - do you know what we're missing here?
