Hi all, I'm relatively new to microcontroller programming and I'm having a few problems with a current project that I would appreciate help with. I'm using MSP430G2553 and Energia to control the speed of two vibromotors. To this I use three pushbuttons, one to change from one motor to another and two more(up and down) to increase/decrease the speed. I have 3 interrupts to do all this and I copied the code below. The program works mostly but sometimes it acts randomly, for example, increasing the speed when I press the decrease button, or not responding at all. My questions are these, they are quite simple but I am struggling quite a lot and I want to understand the basics good: 1). Am I using the interrupts correctly? Do I need to put all of them in the setup routine? Also, I have too much code in the interrupt functions, but not sure how to fix this. Should I just poll the flags in the functions and do the motor speed updating in the loop routine? Basically, and help and comments regarding the interrupts would be very helpful. 2). How do I use switch debouncing for more then one switch? I used the Energia example previously to debounce one switch but it seems complicated using that for 3 switches. int reading = digitalRead(buttonPin); if (reading != lastButtonState) { lastDebounceTime = millis(); } if ((millis( ) - lastDebounceTime) > debounceDelay) { buttonState = reading; } My current code: up_down_test.ino Thank you a lot in advance!

how do i add math.h (the arduino library) to energia? or is there an equivalent library i can use that includes math functions. And where could i find either of those. thank you

Guys, I am having some problems with the CapTouch library and need some help from the experts to resolve this. I modified (stripped) the CapTouch button example an uploaded that code to a G2553: #include <CapTouch.h> #define LEFT_BUTTON 10 #define MIDDLE_LED P1_6 uint8_t state = false; CapTouch left = CapTouch(LEFT_BUTTON, TOUCH_BUTTON); void setup() { /* Use the middle LED to indicate touch */ pinMode(MIDDLE_LED, OUTPUT); } void loop() { /* State will be 1 if any of the buttons was touched, otherwise 0 */ state = left.isTouched(); /* Turn on the LED if any of the buttons was touched */ digitalWrite(MIDDLE_LED, state); } This code runs fine for over 20 hours but then stalls. The the green led (as defined in the code) is constantly on and the board no longer responses. Any clues to what might cause this behaviour?
