Just to see if all the conversion machinery hung together, I added the PWM component for the Mesa 5I25 card to the Kicad-to-HAL library:
The top symbol provides the reference stem for the per-group frequency controls and the second provides the stem for the per-PWM controls.
It requires conjuring one PWM in the FPGA:
The corresponding lines in the HAl file:
setp hm2_5i25.0.pwmgen.00.output-type 1 # parameter.116 setp hm2_5i25.0.pwmgen.00.value 0.5 # parameter.115 setp hm2_5i25.0.pwmgen.pwm_frequency 10000 # parameter.114 … snippage … net Machine-Is-On <= halui.machine.is-on => and2.13.in1 hm2_5i25.0.pwmgen.00.enable
And then it just worked:
It’s not useful with the Sherline driver box, but I find it much easier to contemplate simple schematics than to puzzle out HAL code.
