This is the firmware repo for the Core Electronics PiicoDev® Buzzer Module
This module depends on the PiicoDev Unified Library, include PiicoDev_Unified.py in the project directory on your MicroPython device.
| Parameter | Type | Range | Default | Description |
|---|---|---|---|---|
| bus | int | 0,1 | Raspberry Pi Pico: 0, Raspberry Pi: 1 | I2C Bus. Ignored on Micro:bit |
| freq | int | 100-1000000 | Device dependent | I2C Bus frequency (Hz). Ignored on Raspberry Pi |
| sda | Pin | Device Dependent | Device Dependent | I2C SDA Pin. Implemented on Raspberry Pi Pico only |
| scl | Pin | Device Dependent | Device Dependent | I2C SCL Pin. Implemented on Raspberry Pi Pico only |
| addr | int | 0x08 <= addr <= 0x77 | 0x5C | Manually specify the address of the connected device. For when a sofware address is set on the device |
| id | List: [id1,id2,id3,id4] | (1=Closed, 0=Open). | [0,0,0,0] | Hardware switches change the device address - Abstracts the need for user to look up an address, simply input the switch positions. Alternatively, use addr for explicit address. |
| volume | int | 0:2 | 2 | Set the buzzer volume 0=quietest -> 2=loudest |
Play a tone at frequency Hz for duration ms
| Parameter | Type | Default | Description |
|---|---|---|---|
