CCS/MSP432P401R: Transmitting GPS Coordinates

Tool/software: Code Composer Studio

Hi,

I'm trying send GPS (adafruit Ultimate GPS FeatherWing) coordinates to another location using XBees and then displaying GPS data on an LCD (Sharp 96 Booster Pack) using CCS. I was originally using Energia but I think it might be easier with CCS although I did have functioning code for displaying the parsed GPS data on the serial monitor (Energia). These devices involve 2 pairs of Xbees (4 total 2 different ranges), 3 MSP-EXP432P401R (Black Version), the GPS and the LCD. I wanted to know if there were any examples that demonstrate taking in data from one UART device and transmitting it to another UART device. Also what recommendations do you have for which UART pins I should use. I plan on using pins 3.2 and 3.3 for one UART device but I wasn't sure which other pair of pins I should use.

Thanks in Advance

Hi,
The examples provided in resource explorer are loopback applicactions but you should be able to remove and apply the appropriate pieces for your application.

Please let me know if you have additional questions.

Ok I ran these examples but how do I check that its working. For instance is there like a screen where I can see whats being transferred or do I need to attach something (GPS) to the controller first? Sorry I'm very new to micro controllers and CCS.

You could use a serial tool like RealTerm to send data from the PC. Alternatively, you could use multiple launchpads and have one transmit to the other and watch in the debugger variables update.

For looking at variables in the CCS IDE, you can set a breakpoint and change the properties (right-click on breakpoint to open dialog box and select breakpoint properties). Change the breakpoint action from remain halted to update view and select the Expressions view in which you should select the variables you want to look at.
