  1. In case it might be of use to someone, I've posted a Youtube video and created a Github repo dealing with an alternate way of multiplexing 7-segment displays that has a greatly reduced parts count. It's multiplexing by segment instead of by digit. The video shows this method implemented with an MSP430G2553. The Github repo has demonstration Arduino Nano sketches, but they should work as-is with Energia except for the pin assignments. The video is on my local OSH group's channel, and I can't respond to comments there, but will answer questions here if there are any. https://www.youtube.com/watch?v=8w09Zy8MQrc https://github.com/gbhug5a/7-Segment-Displays-Multiplex-by-Segment

    My MSP430 based analog test bed.

    This is a project I made while I was learning about the MSP430's ADC10 peripheral and messing with multiplexing of 7-segment LED displays. It is a test bed for analog sensors where the 10-bit value of the analog input on the MSP430 mcu ( a MSP430G2252 in this case ) is displayed on two 2-digit 7-segment displays, which are being driven via a TPIC6B595N Power Shift register ( the SPI is currently bit-banged ). This has come quite handy for testing sensors quickly for my robotics projects and such. Here is my blog post that goes into the project in detail: http://emdinventor-blog.tk/msp430-based-analog-test-bed/ Github repository that contains the code for this project: https://github.com/emdarcher/msp430-7seg-mux1 pictures of the result:
