Prepare

Enable I2C

sudo nano /boot/config.txt

Ensure that I2C is on, and then restart the system.

sudo reboot

After restart, address 48 can be detected by I2C address detection command.

i2cdetect -y 1

connection

Ensure that jumper caps are connected to PCF.

Running code

Download sample code pcf8591

cd pcf8591/

sudo python pcf8591_adc.py

Phenomenon
