RTCC with CMOD

Question

Hello there, as far as I know all PIC32 chips have integrated RTCC capabilities. On the Uno32 board RTCC can be used after soldering an oscillator to a spot for it marked as X2. What about the CMOD board? It has a PIC32MX150F128D, but I am unable to find the location reserved for soldering in the oscillator.

So my question - how does one use RTCC with the Chipkit CMOD microcontroller module? Thank you in advance!

Hi ww1dm1,

The chipKIT Cmod does not have any direct spot where you could solder on an external oscillator. The closest you could get is by attaching the oscillator to silk screen pins 29 and 30 and adding in some appropriate external capacitors. These two pins do have 200 Ohm series resistors present on them though, so I don't know how that would affect the external oscillator timing.

Good luck!

Thanks,
JColvin
