Seeedstudio Grove interface
Grove is a modular, standardized connector prototyping system made
by the company Seeed studio.
The Grove port only supports the I2C Grove modules. We have tested only a few modules, but this should be the list of module compatible with this port.
The GPIO port used for Grove are:
- GPIO 44 - SDA
- GPIO 45 - SCL
Install the i2c-tools package by typing:
$ sudo apt update
$ sudo apt install i2c-tools
then check if your module is detected on the I2C bus by using this command:
$ i2cdetect -y 1

config.txt definition
To use the GPIO 44 and GPIO 45 lines as I2C bus insert this line in /boot/config.txt and reboot the Raspberry Pi.
#Set the I2C1 interface on GPIO44 and 45
