Resolved.

audricsaragih commented 3 years ago

Could you tell me please how you solved this?

vijaybande commented 3 years ago

1.) Make sure that the both i2c are enabled on the board i.e i2c-0 and i2c- 1 2.) Connect the arduino slave 08 to i2c-0 and arduino slave 09 to i2c-1

But may I know how it is working in the link given below ?? https://youtu.be/Uz_i_sjVhIM

Yes I've done that both. But when i run :

i2cdetect -y 0

or

i2cdetect -y 1

It didn't catch any adress I'm stuck there too

vijaybande commented 3 years ago
