scampos 0 Posted December 16, 2015 Share Posted December 16, 2015 I'm trying to understand the two possible configurations of the headers on the MSP430G2, rev 1.5, at the top near the border between the emulator and the uart. The silk screen seems to indicate that one configuration is appropriate for hardware uart, and the other configuration is appropriate for software uart. I'm wondering, why does it matter? Whether using a software uart or chip with a hardware uart on board, either way doesn't the TX pin of the MSP still need to go to the RX pin of the emulator (likewise for RX-TX) in order to get data back and forth from a PC? And when the direction is rotated, this seems even stranger since it looks like we're connecting TX-TX and RX-RX. So what's really going on here? Thanks Quote Link to post Share on other sites
