Servo support?

[waseltzer]

Is it possible to add support for servos to the SX1509 library?
Seems that the PWM functionality could do this.
Need 50 Hz pulses between 1.0 and 2.0 milliseconds.

This is kind of late, but while looking for the answer to the same question I bumped into this page. Looking at the datasheet I see that the internal clock is 2MHz and divider is 3 bits so you can't generate less then a couple of kHz with this device, far from the required 50Hz. As I understand, there is an option to use an external clock (maybe 50Hz from an arduino pin?) and make it work, but I haven't tried it, it's only theoretical and not very elegant either.

This is even later 😆 but there is the possibility of doing this using the blink functionality.
