Trying to integrate HART protocol into a sensor design that uses the MSP430 as the microcontroller. I am using an FSK modem to modulate/demodulate the signal from the micro to the 4-20mA analog line. According to my research I will eventually have to configure the micro by programming the universal asynchronous receiver transmitter (UART) to receive and transmit 11 bit (includes start, stop, and parity bit) in a half-duplex manner. The MSP430F149 have two UARTs (UART0 & UART1). I was wondering if it is going to be easier to program one to receive and the other to transmit to avoid data collision. I was going to try to use IAR workbench to flash the micro and hyperterminal to test communication but am unsure if this will work. Any suggestions would be helpful
