Hello Community
After a few years with Stepper driven CNC machines I decided to build a real Servo CNC with 4 Axxis.
I found EMC2 and tried something with the parallel Port (to slow !).
So I ordered a Mesa 5i20 Card read the documentation and designed four PWM Amplifiers with low active Inputs.
Most everything works well, but the PWM polarity is wrong !
I need pure high Level on 0% PWM and a pure low level at 100% PWM.
After some hours with the Hal pins I decided to change the BIT File for the Mesa Card.
I want to add a new hm2_5i20.0.pwmgen.00.output-type (4) for inverted PWM polarity.
I´ve downloaded the ISE 10.1 Webpack from Xilinx (what a mess).
Can anyone help with a tutorial adding the sources and compiling a new .BIT file for the FPGA ?
Thanks for any Help
Best Regards Bernd
