Trouble connecting GPS and XBee to MSP432


Recommended Posts

Hi

I'm new to using both the MSP-EXP432P401R (Black Version) and Energia. I want to attach a GPS (adafruit Ultimate GPS FeatherWing https://www.adafruit.com/product/3133) and an XBee to the micro-controller so I can send GPS data to another MSP432 micro-controller with an XBee. I see I can attach the GPS or XBee to the hardware uart pins 3.2(Rx) and 3.3(Tx) their listed as pins 3 and 4 respectively on the Energia Pin Map (https://cloud.githubusercontent.com/assets/951776/15053945/5f47bac6-1305-11e6-9ab5-c71d425194ce.jpeg) but where can I find two other hardware pins for attaching a second the second device? Or can I use some other pins (SPI or something) to have both items connected to the micro-controller?
