Driving 12V with SoftPWM
ERROR! The markdown supplied could not be parsed correctly. Did you forget to surround a code snippet with "~~~~"?
For my current project I need a 12V Analog output. Today I did some first tests. [[embed url=https://www.youtube.com/watch?v=oyWTSpI9OXk]] # Getting 12V I used a voltage regulator which is rising the 5V of the Pi to 12V. The reason is, that I want to be able to power the whole thing with a standard power bank. # Getting a PWM signal I used the SoftPWM FB from the [GPIOMods](/drv/gpio-mod) project to get a PWM signal out of GPIO4. # Driver To drive a voltage that is higher than 3.3V, I used a usual combination of an NPN and a PNP transistor. I just had not the correct resistors at hand, why lower volatages can't be correctly reached (you will notice in the video ;) )
Hi, loading this project locks-up my Codesys V3.5 SP16 Patch 2. I have tried for sometime to conquer PWM via Codesys & my RPI 2 but am making no progress due to my limited knowledge. Can someone point me to an appropriate resource or solution?
Thx
