CCS/MSP430FR2000: Make a 16 bit data from UART for RTCMOD

Prudhvi Sagar

Part Number: MSP430FR2000

Tool/software: Code Composer Studio

Hello,

I am receiving a data via UART from a host MCU which I am loading into RTCMOD. RX buffer of UART is 8 bit whereas RTCMOD is 16 bit. I am trying to maximize my RTCMOD count, so I have to receive 2 times via UART and then load it into RTCMOD. How can I do this, I new to MSP430 programming.

Regards,

Hello Prudhvi,

I recommend having a look at our code examples for the MSPFR2000, which can be found below. There are a couple UART examples as well as RTC examples that should be useful. Let me know if you have other specific questions. Thanks!

Hello,
I am able to work with both RTC and UART but unable to append 2 bytes to make a 16 bit data.

unsigned char lowbyte = receive_somehow();  // (reorder as needed to match data ordering)
unsigned char highbyte = receive_somehow();
unsigned rtcword = ((unsigned)highbyte << 8) | ((unsigned)lowbyte << 0);
