# Climb into the root akshay - nano: ~ $ sudo su # Set the GPIO # gpio79 is pin 12 on the Jetson. Run the following commands in the terminal. Connect an LED to the J41 expansion header with the +ve end to pin 12 and -ve pin to GND. The current plan is to load a known-working ArTICL build onto an Arduino and try to get it to talk to ArTICL on the MSP432 to debug what the non-MSP432 endpoint is receiving (and sending).While the pins on the header provide very low current, it is sufficient enough to light up a small LED. Switching to a scheme where pin reads involve a unanimous voting scheme over 16 samples helps a little, in that a single byte is received successfully, except that the byte received is a nonsensical (but consistent) value. Using the existing code largely yields no bits received at all. Timeouts have been temporarily lengthened because they're based on numbers of loop iterations, rather than the correct solution (using timers), they need to be longer on faster uCs.

TI Forum help about MSP432 interrupts (doesn't work with Energia?):īecause it seems to be documented in shockingly few places, here's how you translate bank+pin-style pin names (ie, P1.0 or P2.4) to Energia numeric pin numbers (for example, the LED pin is not 2, as some documentation claims it's 7 :Įdit: I'm currently working on getting a simple ArTICL sketch working first, and not having much luck: I'll be documenting my adventure in this topic.įirst, here's what I've found so far in futile efforts to get a simple PWM interrupt working within an Energia sketch: A slightly more complex goal that I've set myself is to try to control DCC-enabled model trains with the MSP432 and a graphing calculator.

The most obvious task is to try using Energia, TI's Arduino IDE fork for their Launchpads, to port ArTICL programs to the MSP432. I recently was fortunate enough to receive two MSP432 Launchpad development boards, and I've been hoping to use them for a few calculator-related projects.
