I believe there are a few people using the Pico Systems brush PWM servo amp with mesa controller boards. We are using this combination on our mill. I'm not using any special boot-up HAL code for the servo amp. When dry-testing the servos on the bench (no load attached), this boot-up sometimes

[Emc-users] adding a thread for charge pump

2011-01-13 Thread Tom Easterday
I have a charge pump board that wants a 3000-15,500Hz signal. That is slower then my base-thread so I want to create another slower thread for the charge pump. I have tried many combination using loadrt threads but can't get it to work. The problem (or one problem) is that threads says that
