Well seems like my brain started working again and I found out that this
construction fits that task:
os.system("halcmd setp hm2_5i25.0.pwmgen.00.scale %s
"%(c.find('SPINDLE', 'MAXRPM')))
On a side note according to this post:
https://www.mail-archive.com/[email protected]&q=subject:%22%5C%5BMachinekit%5C%5D+Machinekit+Advanced+HAL+Tutorial%22&o=newest&f=1
Parameters are depreciated in machinekit-hal so,
It could seem like a great idea to convert all the Params in hm2 to pins ?
Unless there are worries about breaking too many existing Machinekit mesa
hm2 configs ?
Best wishes
Michael Brown
