I had to install i2cdetect:
Rebooted, and got the following:
Verifying that I2C is enabled through raspi-config, rebooted but still didn't see any devices connected to the bus. What's interesting is that listing the buses only shows this:
Trying with the `i2c1-bcm2708` lists the bcm2708 but the pi still sees no devices connected to it:
Could the i2c1_baudrate be affecting it somehow?
Code:
sudo apt install i2c-toolsRebooted, and got the following:
Code:
pi@retropie:~ $ sudo i2cdetect 0
Error: Could not open file `/dev/i2c-0' or `/dev/i2c/0': No such file or directory
pi@retropie:~ $ sudo i2cdetect 1
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-1.
I will probe address range 0x03-0x77.
