BQ34Z100-G1: BQ34Z100-G1 four leds issue

user44411751

Part Number: BQ34Z100-G1

The BQ34Z100-G1 use for four LEDS, how to set the register about LED configurator? I only see "LED/COMM Configuration" as below, any other setting?

We refer to the website application. Multiplexed communication pin for LED display. The p1 and p2 pin LEDs are OK, the other two LEDs can't display.

Maybe you can try below way to check it. The information is from BQ34Z100-G1 EVM user guide.

For four direct LED mode, place jumpers on A, B, C, and D. (Note: This configuration is only available when using HDQ communications mode.)

Hi user44411751,

Che yi Su is correct, for direct 4 LED mode, the jumpers above will need to be placed and the device will need to be put into HDQ communication mode.

Once the device is put into HDQ communication mode, it cannot be brought back to i2c mode, so please perform all testing and calibration prior.

Sincerely,
Bryan Kahler
