IIC module is mentioned in changelog of QPY_V0001_BG77_FW. However in hardware design document for BG77, pins I2C_SCL and I2C_SDA have description I2C serial clock/data (for external codec).
Is general operation of I2C bus supported or is it only limited to external codec?
hello
BG77LA I2C pins are as follows
I2C0 (SCL —PIN37, SDA — PIN5)
I2C1 (SCL —PIN57, SDA — PIN1)
I2C2 (SCL —PIN9, SDA — PIN63)
Note, however, that the current firmware version does not yet support I2C.You can debug it by using GPIO to simulate I2C first.
thanks.

Is this a mistake or is IIC/I2C already supported? I don’t have any BG77 board yet to test with.
@Felix.feng-Q could you please comment on my previous post? Thank you.
hi~, danielm
Sorry for the late reply.
May I ask what is your firmware version?
The latest version already supports I2C
