MSP430F5529 LPM Questions
ConfusedCoder posted a topic in GeneralHi, I was working on interfacing my MSP430 with a 4x4 keypad and I stumbled upon this application report. Then I looked into the specific low power modes of the F5529 and noticed that there was a LPM4.5. The application report uses LPM4 as it isn't the same device, and I was wondering if it was possible to use LPM4.5 as the device was waiting for keypad input as my goal is to minimize power usage.
MSP430G2553 & HT16K33 Issues
ConfusedCoder posted a topic in GeneralHi, I'm having a lot of trouble figuring out how to communicate with this Adafruit 7-segment display. I've looked through the Adafruit LED library, seen non-MSP microcontrollers working with the code, tried understanding the HT16K33 datasheet. I've even recorded the SCL and SDA signals from my Arduino connecting with the 7-segment. However, I'm still not sure how to get it to work with my MSP430G2553 or even how to get started. Though, I have looked into the MSP430 example code for i2c communications with the MSP430 as the master. Is it as simple as just converting the Adafruit LED l
