I would like to use the GPIO I2C
Can you suggest a solution
Do you mean physical I2C bus or GPIO-to-I2C?
Check GPIO Mapout for information.
I2C on GPIO (A OR B)Kadas VIM
A is already with pull-up register, and B need external pull-up register if used as I2C.
You can check the schematic for further details:
How to access programming (Kernel) to i2C
thank you for your collaboration
It’s common linux driver acknowledge, you can Google for that
You can not give me an example of an I2C script on kadas vim
drivers/amlogic/display/backlight/bl_extern/i2c_lp8556.c is a exmaple on Amlogic platform for your refrence, you can also research more examples on drivers/amlogic folder:
$ grep -rn i2c drivers/amlogic/
I work on it I will let you know of my work
