I'm using Raspi 5 to communicate with an Arduino via I2C.
In `raspi-config`, I enable I2C, and I set parameters in `/boot/firmware/config.txt`:
I set the address at `0x08` for the slave.
But the slave device is still missing:
With response:I use serval slaves and get the same issue.
Diagnostics I have done so far:
In `raspi-config`, I enable I2C, and I set parameters in `/boot/firmware/config.txt`:
Code:
dtparam=i2c_arm=ondtparam=i2c_arm_baudrate=400000But the slave device is still missing:
Code:
i2cdetect -y 1Code:

Clik here to view.

- `raspinfo` shows a suspicious message:after reboot, there is no such message in `raspinfo`, but it shows again after I run `i2cdetect`.
