i2c speed checking

Active today
Viewed 17 times

I could not find this information anywhere. Where can I find the current i2c speed? It’s not in dmesg, and in /sys/module/i2c_bcm2835/parameters/ I only have a file called “debug”.


The Pi’s I2C bus defaults to 100 kbps.

It may be changed by the i2c_baudrate setting in /boot/config.txt.

Those are the settings used by the Linux driver.
