Meaning of underscored pins on ChipKit uC32

Question

Hello there!
I am a newbie using ChipKit uC32, and wonder what is the meaning of underscored pins on J5 and J6. Pins 3, 5,6,9,10
May I use all J5 and J6 pins as I/O?

Thanks in advance for any help.:)

Hi @Digisol,

I believe you can use all of the pins on j5 and j6 as digital I/O. Some of the I/O pins on J5 and J6 are also used for I2C and output compares and .... I would look at the pinout tables 3.70-3.7.2 here(reference manual) for more information. Here is the resource page for the uC32 as well.

cheers,

Jon

The underscore means that it is an "analog output" pin. This is done via a PWM operation. So those pins can be used to run the analogWrite functions.

Thank you for the quick response! I failed to find it on reference manual, resource page and Internet.:D
