Kirk, Thanks for the info. I'll check it out.
I don't think we need 24kHz. The default pwm signal is 100Hz and gave me 2.5 volts. I changed the frequence in the hal config to 200 Hz and the output was approx 5V, so I guess the max voltage on the C11 board is reached at 400Hz. Never experimetd with hal before, will take me some study and testing, before I can get back.
