SX1509 analogWrite not working
Posted: Fri Jul 21, 2017 6:51 am
Hi
i have just hooked up a SX1509 board to an ESP8266.
Breathe seems to work, but analogWrite does not.
I'm not sinking current but I'm sourcing it, as I have hooked up NPN Mosfets (IRL3708) and then subsequently the LEDs.
When I set a pin to analogWrite, it has about like half of the LED brightness and doesn't change, no matter what value I set analogWrite to.
Should analogWrite work with NPN MOSFET setups and sourcing current? The example specifically mentions that analogWrite expects sourcing current. Do I have to modify the library in any way?
Thanks
