m0nk37 0 Posted January 22, 2017 Share Posted January 22, 2017 Hello, Im working with TM1809 RGB LEDs on an MSP430G2553 over SPI (3-wire) data transfer. Im running into issues with timing and im not sure if its due to voltage or something else, and could really use some help. https://www.deskontrol.net/descargas/datasheets/TM1809.pdf on page 2 says that these lights require 4.5-5.5V, and i know the MSP430 is at 3.3V, is this the reason? My code below achieves the ability to set the RGB LEDs with about 95% success rate, i run into issues attempting to animate the colors or if i send it the same color over and over it will send bad data 5% of the time and fail. If its not the voltage, can someone take a look at my code and let me know if they have any ideas? Thanks for your time! main.c Quote Link to post Share on other sites
