  1. Hello, I am trying to port Sparkfun's library to get the apds-9960 Gesture Sensor working on my Tiva C 1294 board. I set up the library like you normally would with ardunio while changing the interrupt pin and uploaded the code to my board with no issues. The only problem is when I go to serial monitor I get nothing printed to screen. Are there any other steps I need to take in order to convert this code to work on my Tiva board? I also tried moving to code composer studio but I cant find many clean tutorials on how to use it. I also have a MSP432 that I might try to get his working on if its supported better. Thanks! /**************************************************************** GestureTest.ino APDS-9960 RGB and Gesture Sensor Shawn Hymel @ SparkFun Electronics May 30, 2014 https://github.com/sparkfun/APDS-9960_RGB_and_Gesture_Sensor Tests the gesture sensing abilities of the APDS-9960. Configures APDS-9960 over I2C and waits for gesture events. Calculates the direction of the swipe (up, down, left, right) and displays it on a serial console. To perform a NEAR gesture, hold your hand far above the sensor and move it close to the sensor (within 2 inches). Hold your hand there for at least 1 second and move it away. To perform a FAR gesture, hold your hand within 2 inches of the sensor for at least 1 second and then move it above (out of range) of the sensor. Hardware Connections: IMPORTANT: The APDS-9960 can only accept 3.3V!
