BreadPi is a multi-purpose HAT(Hardware Attached on Top) that consists of a mini breadboard on top, ADC, a Programmable Buzzer, Programmable LEDs, push buttons, and 5V tolerant inputs at the Operating Voltage of 3.3V DC at a single place. SB Components developed BreadPi with advanced features like independently controllable LEDs, inputs(Analog & digital), a mini breadboard that helps the user to prototype their projects in an efficient way.
-
First enable i2c interface by running "sudo raspi-config" command then select interfacing options >> I2C >> click on enter to enable it.
OR
-
You can also use GUI to enable i2c, click on Menu > Preferences > Raspberry Pi Configuration > interfaces, Then enable I2C
-
Install breadpi package on your Raspberry Pi using
pip3 install breadpi
or
python3 -m pip install breadpi
- import the module with
from breadpi import BreadPi
- Access PCF8591 or GPIOs directly
bread_pi = BreadPi()
data = bread_pi.read_analog(register=1) # Read Data from AIN1
bread_pi.write_analog(register=1, value=100) # Covert Digital data to analog
- To use BreadPi LEDs and buzzer-
bread_pi = BreadPi()
# To Turn On LEDs use led_on method
# Use LED number as argument
bread_pi.led_on('L1')
bread_pi.led_on('L2')
# Or use Pin numbers
bread_pi.led_on(38)
bread_pi.led_on(40)
# To Turn Off LEDs use led_off
# Use LED number as argument
bread_pi.led_off('L1')
bread_pi.led_off('L2')
# Or Pin Number
bread_pi.led_off(38)
bread_pi.led_off(40)
# To Turn On or Turn Off buzzer
# Use buzzer_on, buzzer_off
bread_pi.buzzer_on()
bread_pi.buzzer_off()
or
- Take digital inputs from buttons using button function of BreadPi class.
bread_pi = BreadPi()
# To use switches Of BreadPi
# use btton function with pin number or switch number of BreadPi as args
status = bread_pi.button('SW1')
status = bread_pi.button(31)
You can pass string printed on BreadPi like, 'L1' or 'SW1' or customized pin number like 29, 31 directly to the functions.
