Very simple question here. How many (and which) of the Portenta's pins can be used as simple digital inputs/outputs. I am not well versed in microcontrollers, but I want to assume that any pin labelled as digital in the Arduino Portenta breakout board documentation can be used for digital reading and writing. Here's a link to that documention:
If all you need is to switch outputs ON and OFF, the Portenta is way overkill. There's are so many ways you can mess it up, and you end up with this orange LED of hell.
Really what I am doing is capturing ADC output data and then processing it. I need a lot of IO that is relatively fast, and a second core for signal processing. So I believe the portenta is well suited to my application.
