Hello. My question would be: can I control the speed on the steval ptool 1v1 board with a pwm signal or just an analog voltage? Or it is possible to give a pwm signal to the analog input? Thanks in advance for the answer. Bela

Hello @BPara.1​,

you have different options to generates the VSPEED voltage signal (PA3):

  • connect an external trimmer to J9 connector (replacing R18 with 0 ohm)
  • apply an analog voltage value at J9 connector (between 2 and 3 pins)
  • apply a PWM signal at J9 connector (setting a proper value for the R19-C18 network)

I hope this post can help you; if so, consider to mark it as best answer by clicking the label "Select as Best".
