RPI's 5v PWM to 0-10V analog for VFD
Hi
I have the Protoneer cnc hat to connect to my Micromaster 440 and need to convert the 5V pwm into 0-10V analog. I have found some opamp + rc filter schematics for it but can't really say if they are any good. Anybody here done that before? (sure!) Would appreciate an "I have this and it works perfect"-example.
BTW this thing of Bcnc on RPI is totally kick ass! Can't wait to get my build running :)
Thanks

Take a look at this old thread, in post #34 I shared the schematics that worked (and still is working) for me.

Here is what it looks like in flesh:
