MSP430G2452 acting as a TMS0803 calculator chip. Emulates TI Datamath 2500 and Sinclair Scientific. There seems to be some interest in building this emulating calculator so I will start a build thread. /EDIT add youtube video, different versions of PCBs, try to get everything in one place. 1st July. 2014 /EDIT add build tips down under, here 8th July, 2014 I got introduced to a web based calculator emulation via this thread. I got interested and start playing w/ the idea of implementing the emulation on an msp430, my code is based on Mr Ken Shirriff's work from the follow
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 d
