SDA and SCK pins #7

Closed montechristos closed 2 months ago

montechristos commented 2 months ago

Hello,

I have been trying to find the schematic diagrams to identify the i/o pins that I can use for SDA SCK Can you please help?

Thanks in advance

You can check the C6 datasheet:

Thanks. Exactly what I was looking for. (maybe a link for the datasheet in the doc section?)

One more question please: are these pins accessible on the M5NanoC6? Which pins can be accessed?

Actually, the I2C pins used can be chosen from any GPlOs, These two pins(LP_GPIO6 ~ 7) have the characteristics of low power consumption

FCPotesD commented 1 month ago

As only GPIOs G1 and G2 are accessible on the M5NanoC6, is there any way to set G1 and G2 to be the I2C pins??

I've tried every wiring combination I can think of and no matter what I fail to make any I2C connections.

I am desperately trying to get the BNO055 9DOF IMU working through the 4 available grove pins, but it doesn't seem to work how I expect.

Hi @FCPotesD ,

Could you paste some code to here? We can try find the reason.
