Beginners • Re: Bit banging

Code:

"dtoverlay=i2c-gpio,bus=3,sda=17,scl=27"

What kind of arm computer you have?

There are no hardware I2C-gpio at these GPIO pins on Raspberry Pi.

thats exactly what i2c-gpio is for, it tells the kernel to just take any 2 gpio, and bit-bang i2c on it, so you can do i2c on pins that dont support it

but it would be far simpler to use pins that do support i2c, as you showed
