RGB LED Matrix Panel with MSP430

by marcusfenixwm on Sat Jun 01, 2019 12:50 pm

Hello,

I'm working with a 16x32 RGB LED Matrix Panel from Adafruit, and until now i was using an Arduino UNO.

I would like to know if it possible to use an MSP430 launchpad with the Matrix Panel, using the same librabries (of cource, changing whatever is necessary on the header files.
If it isn't possible, has anyone ever used the matrix with a MSP430?

I don't know about using the libraries without modification but using the MSP430 should be OK. Check the MSP forums for info on using matrix panels.

The Launchpads have only 3V3 logic. There is 5V power (direct off the USB), but no level shifters.

The 16x32 panel product page claims it needs 5V logic, though it also says the panel works with the Metro M0/M4 (3V3 logic), and I don't see any level shifters in the setup Guide, so maybe it'll work anyway.

I don't have much experience with Energia, but, if it's any indication, "doesn't work in Energia" questions seem quite rare on the TI forum.
