DAC synchronization

Post by swchiow » Mon Feb 17, 2020 8:19 am

Is it possible to synchronize two DAC outputs? I want to update both channels simultaneously on single external trigger. The manual of the microcontroller says "synchronized update capability". I hope it's doable. Thanks. - SC

If you can tolerate a small amount of latency you can update each in turn in an interrupt handler. To use the native chip capability you'll need to code it at register level using the stm module.
