I have PCA9685 clone and when i tried to use it i accidently wire it wrong. I put vcc to the ground and ground to vcc. After correcting it i tried some codes and suddently i lost connection to the PCA9685. I replugged everything i got connected to the PCA9685 but it wont acknowledge offset address (0x41). It only acknowledges 0x00 address but nothing else. I examine the logic analyzer but nothing was wrong there either. Can anyone help me ?
That does not answer my question. What makes you sure the chip actually survived that reverse polarity incident? Have you tried replacing it with a known-good, spare one?
