A while back @omnicron generously offered up some surplus boards sporting a MSP430F149 and a good mix of conditioned I/O on the board including a couple of 5.8psi pressure transducers. I feel that this, along with the programming header on the board, makes it a good all-around board for general purpose projects. The board also supports a standby NiMH battery (6v, 1800mAh) with charging/discharging capability and voltage monitoring all controlled by the MCU. The battery switches in via a relay upon primary power loss. One of the pushbuttons is configured in hardware to be used as a soft power
After searching for more than a week I've been unable to find an example of a serial port program for the 'f149 variant that can send and receive. I was able to get Don Binder's send only program to work fine but I had no luck with tx. It's not a matter of something being at the right frequency as there is no signal coming out at all. I'm new to msp430 but have used atmel parts and uC's since the late 1970's... Most examples online use newer chips than the msp430f149 and it doesn't have calibration code so I did this: //BCSCTL1 = CALBC1_1MHZ; //DCOCTL = CALDCO_1MHZ; //BCSCTL2 &=
