Hiii there, Is there any library available for PCA9634 8-channal-PWM chip?.. I am currently working on PCA9634 chip with Photon2 but could not find any Reference of working with Particle device. Any reference available working with 8-channal PWM chip?

Have you seen this? Particle Web IDE Write and flash code to your Particle devices

Thank you for your Response. I already seen… Particle Web IDE Write and flash code to your Particle devices PCA9534 work as IO Expander. My requirements is PWM which is not used in PCA9534 so that this is not compatible to my requirements…

My bad, sorry :blush: :see_no_evil: However, have you found an Arduino library for that chip? If it’s anything like the PCA9534 it would only use standard I2C communication and hence should be easily portable (with virtually no changes required). You could give this one a try. [image] Gi…

[image] ParthPatel: but this library gets some error in compilation… In that case it's best to also post which errors you see. There might be simple solutions to many of them. Unfortunately I still didn't receive a Photon 2/P2 so I can only talk from theory :wink:

is this the same error as what you reported here? [image] P1 to P2 migration Firmware Hello, I am try to compile P1 code into P2 using Visual Studio Code i do necessary changes in my firmware according to P2 but there is an error while compile firmware… #################…

No no there is an different error . This error is not related to PCA9634 + Photon2 topic…
