We are using an arduino pro mini as a dedicated SPI to PWM converter for a RPI0 controlled Robot. We are sending a constant stream of data and are getting a lot of errors. These errors are causing lag and instability in our PWM controlled steering servo and motor ESC.
We think there could be an issue with the SPI speed setting or our Sketch but not sure.
Looking for someone who could help us with this.
