MSP430F5529 - Unusable ADC noise/jittering with TI's FRC Gamepad code

Recommended Posts

I'm using the FRC Gamepad Tool to load the TI-supplied firmware for a USD HID joystick with a KMA210 magnetic angle sensor. I have a voltage divider taking the KMA210's 5V max output to 3.3V, and when plugging in the MSP and checking the windows game controllers, an axis does respond when I turn a magnet near the sensor, but the reading is all over the place. Bouncing back and forth by 40% of the whole angle range. I've tried using an external 5V supply, tried changing the sampling on the ADC, the Vref, the clock multiplier, the wires, the input pin, just about everything. 

Does anyone have any advice?
