I'm attempting to add support for a pseudo digital protocol to a project of mine. I'm attempting to implement the dShot protocol for controlling ESCs on my thrust stand, and having some issues. The TivaC doesn't appear to have very robust output control. You can see what I'm trying to do here: https://github.com/VirtualEnder/TestStandv2/blob/dev/MQTB_Thrust_Stand/hardwareTimers.ino Basically the protocol uses a modified PWM signal with each bit being 1.67us period with 1250ns representing a 1 and 635ns representing 0, basically encoding a 2048 bit throttle signal with some CRC data and a -
Still new to embedded programming and I am trying to use the MMA8452 accelerometer (datasheet) on SparkFun's breakout board (link). I programmed SparkFun's example program (link) into the MSP430G2553 via Energia with no issues and plotted the serial data in Excel. However this data, for lack of a better word, was "noisy." There would be huge spikes in the data even though the device was sitting still. Sometimes the WHO_AM_I value would be reported incorrectly as well. I found out the board shipped with 10k pull ups so I dropped them to the recommended 4.7k? resistors and the problem

Hey all, I'm having some trouble with a project that checks a pin every hour and should trip a relay if a certain pin is HIGH. Some notes: - this is with the MSP430G2553 chip - it seems to run fine if duration is low (ex: 5000ms) - it worked at least once (triggered buzzer after an hour) when I replaced the relay circuit with a simple buzzer I'm using this relay circuit: And this code using TwoMsTimer library: #include <TwoMsTimer.h> unsigned long duration = 3600000; int relayPin = 14; int moistPin = 15; int state = 0; void setup() { pinMode(
