adafruit_seesaw

An I2C to whatever helper chip.

• Author(s): Dean Miller

Implementation Notes

Hardware:

• Adafruit ATSAMD09 Breakout with seesaw (Product ID: 3657)

Software and Dependencies:

• Adafruit CircuitPython firmware for the ESP8622 and M0-based boards: https://github.com/adafruit/circuitpython/releases
• Adafruit’s Bus Device library: https://github.com/adafruit/Adafruit_CircuitPython_BusDevice

class adafruit_seesaw.PWMChannel(seesaw, pin)

A single seesaw channel that matches the PWMOut API.

duty_cycle

16 bit value that dictates how much of one cycle is high (1) versus low (0). 0xffff will always be high, 0 will always be low and 0x7fff will be half high and then half low.

frequency

The overall PWM frequency in herz.

class adafruit_seesaw.Seesaw(i2c_bus, addr=73, drdy=None)

Driver for Seesaw i2c generic conversion trip

Parameters:

• i2c_bus (I2C) – Bus the SeeSaw is connected to
• addr (int) – I2C address of the SeeSaw device

sw_reset()

Trigger a software reset of the SeeSaw chip
