I am using a Spresense board and the I2C module is working great. However, only the drvname I2C0 is recognized. I2C1 gives the error “Can’t find name [I2C1]” when I try to interface with it.
The pinout in Zernyth only shows a single I2C; however, there are multiple I2C interfaces available on the Spresense (some are on the B2B connector) that I would like to utilize.
How can I enable I2C1?
