Hi Folks.
I need to control the Prop Backpack using I2C. The processors I am working with (Maximite) has a limit of 2 Serial Ports and both are used.
Can anyone advice the best library to use and what to replace?
Many thanks
Dave

I haven't used any of them, so I can't vouch for their reliability. If your I2C master is 3.3V, you can just use the PropPlug header (P30, P31, and Vss) as your interface, sparing the daughterboard connector for something else. The two data lines already have pull-up resistors and would work fine for SDA and SCL.
