Part Number: DRV2667
Other Parts Discussed in Thread: DRV2605LHello.
Sorry being novice again. Now I am trying DRV2667 with Samsung piezo actuator.
But, I tried the simple example found in below, but nothing happens with the actuator.
>8.3.2 Typical Usage Examples
>8.3.2.1 Single Click or Alert Example
THe DRV667 chip is visible onm I2C bus and no error writing to its registers. BUt however after setting GO bit to 1, I can see no movement on the actutator.
Then I tried with another unit of DRV2667 breakout board, another unit of Piezo actuator, but the resulr is the same.
The queastion may sound vague but where I should look into, or which is the step-by-step procedure to diagnose the problem?
I think I may be measuring the voltage on motor output pins from DRV2667.
That should give me some hint?
I am connecting this DRV2667 breakout board to Arduino compatible chip.
