If you previously used raspi-config to enable I2C-1 and SPI, you'll see similar entries near the bottom of the vile. This type of LCD is ideal for displaying text and numbers, hence the name ‘character LCD’. "UU". Now add a new user to the i2c group: sudo adduser pi i2c. i2cbus indicates the number or name of the I2C bus to be scanned, and should correspond to one of the busses listed by i2cdetect -l. I can write to registers using I2c, also i2cDetect works showing all devices. The i2c-tools package contains a heterogeneous set of I 2 C tools for Linux: a bus probing tool, a chip dumper, register-level SMBus access helpers, EEPROM decoding scripts, EEPROM programming tools, and a python module for SMBus access. The core part is running linux commannd line tool through Runtime.getRuntime().exec(), then read and parse the stand out/error and then write to log. If you know something is connected, but you don't know it's 7-bit I2C address, this library has a great little tool to help you find it. This method is used for scanning the I2C Device inside your module that connected to I2C bus in Arduino (SDA, SCL). The I2C bus allows multiple devices to be connected to your Raspberry Pi, each with a unique address, that can often be set by changing jumper settings on the module. 04/20/2017; 2 minutes to read; b; d; In this article.
