MSP430G2553 USCI Hardware UART

Recommended Posts


I guess one possibility is that the J3 jumpers for RXD and TXD could be swapped with jumper wires. Just have to remember to swap them back when wanting to program the device.


I'm pretty sure the RXD/TXD have no involvement in programming. Programming is done via Spy-Bi-Wire and only uses the TEST and RST pins of the chip. I have been successfully programming an MSP430GF2012. It is on a breadboard and the only connection it has to the launch pad is with VCC/GND/TEST/RST.
