My question is this: I have six of these great 30-pin mcu's and the blue LED's all behave differently.
For instance, some mcu's will light these blue LED's when there is absolutely NO code reference to GPIO2. If I set -
Code: Select all
digitalWrite (blu_led, LOW)
This issue is not the end-of-the-world for me. I would just like to understand why these mcu's behave as they do with regard to these LED's.
Thank you.
