WARNING! This program can confuse your I2C bus, cause data loss and worse! No size specified (using byte-data access) I2cdump also reads 0xff all the time irrespective of the value sudo i2cdump 6 0x50 I am facing one problem while doing i2cset and i2cget.But in different board. ![]() Thankfully, Linux has built-in i2c tools that make our life easier (unlike with BBB PWM). The i2c-2 bus is the one that is free for use so we’ll be using that in this tutorial. The i2c-0 bus is not accessible on the header pins while the i2c-1 bus is utilized for reading EEPROMS on cape add-on boards and may interfere with that function when used for other digital I/O operations. There are three I2C buses on the Beaglebone Black according to the AM335X Technical Reference Manual and their memory addresses are: In this tutorial, we will look at how to use the I2C protocol on the BBB and create a simple Beaglebone Black I2C application. This is why most microcontrollers, including Arduino, PICs and STM32 have I2C support. I2C is a popular communications protocol and is used by a lot of sensors and devices.
