Redesign of AMC1280USB motion controller boards

Hi everyone!

First of all, Merry Christmas and Happy New Year!

Black Friday and Cyber Monday Offer


It's this time of the year again and like every year there will be a chance to get the AMC1280USB motion controller in discounted price along with some extras.

For this year I elected to add to the offer free 3D printed stuff!!

New Firmware Update for AMC1280USB


Here is the AMC1280USB Firmware version 2.1c:

Older 2.x firmware revisions can be found here:

Revision History (updated 9/8/2016)
-Added Individual PID values for all 6 motors.
-Added switch to merged single value for PID for all motors for legacy reasons.
-Added new mode for Analog signal (-11v,0,+11v) for Industrial Servomotor Drives (enabled with Jumper S1).
-Added NO limit switch for PWM mode for H-bridges that use only one DIR line (like Pololu's High Power H-bridge).
-Fixed other minor performance issues.

While installing the new firmware 2.1c you may receive a error message "Buffer overflow : [92944] > [65536]".

Look here about the setting in the AVRUBD to make it fit in the memory:
