I just finish the pca9685 driver design and below are my control sequence.
1.Set 0xFE as 133(50 Hz)
2.Set 0x06 and 0x07 as 0
3.Set 0x07 as 0x4B and 0x08 as 1
4.Set 0x00 as 0x00
After the steps, the PWM was generated as what I went, but the signal will stop in a regular period then generated again.
The discontinuous PWM is not what we desired, is there any setting I miss?
