Adafruit 16-Channel Servo driver - port manipulation

Post by xETx »

Hi,
I´am trying to implement the Adafruit 16-Channel Servo driver in my project and use it as an extension board for additional outputs.

Is there a way to call 8 pins (e.g. 0-7) at a time, comparable to the Arduino UNO port manipulation over PORTD? I would like to write 8 bit values on them.
Thank you in advance.

I don't believe so. There is an "all-call' i2c address for sending commands to multiple chips at a time. But nothing for controlling groups of pins within a chip.
