apds-9960 Gesture Sensor Working on TM4C1294XL

[tim3lord 0]

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!

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!

Have you gone through the I²C Check-List?

[tim3lord 0]

@Rei Vilo  Yes, I the sensor runs on 3.3v and I set Wire.setModule(0);  Wire.begin();  in void setup()  I have my wires hooked into SCL (0) and SDA (0)

Hi, any success?I have the same issue:(

[Rei Vilo 695]

Pull-up resistors?

• Are pull-ups installed?

Try 10, 4.7 or 2.2 kΩ for the SDA and SCL lines.
