Hello,
I am currently breadboarding a prototype of my senior design project (handheld reaction time game). I'm using the PCA9685 (datasheet attached) to drive some RGB LED for visual effects associated with the game.
I've had trouble setting up my I2C interface with my Texas Instruments MSP432P401R Launchpad (device user's guide attached). To test I have my interface configured correctly, I want to read from a specific register at startup. However, i cannot find this example on the datasheet.
I can provide more detail about my application and what I have tried upon request.
Thanks,
I have read these pages.
They do not contain a specific example for reading from 1 specific register. I want to this so I can simply verify my interface.
How would I change Fig. 22 to on page 33 to accomplish this task?
You can read the PCA9685 datasheet page30-35 for the IIC operation detail which explain the READ/WRITE these basic operation.
