I'm new to embedded devices and am trying to understand how to use i2cget (or the entire I2C protocol really). sudo i2cdetect -y 0 //or sudo i2cdetect -y 1 The 7 bit I2C address of all found devices will be shown (ignoring the R/W bit, so I2C address 0000 0110 is displayed as hex 03). Обратите внимание, что в предыдущих версиях Raspberry Pi на основной разъем может быть выведена шина 0. In this article, I explain how I integrated Dr. Libraries First of all, download libi2c-dev and the WiringPiI2C libraries as shown…. If you wish to access the GPIO devices via the I2C when the driver is holding the address (i2cdetect returns UU on address), you may add the -f flag to either the i2cget and ic2set commands. I'm using the Pine temp/humidity sensortested with some python code (grabbed from the web and modified) and the sensor works great when using the Pi Bus I2C pins. Maybe someone here can help me. If it doesn't please update your octoprint with the latest release of octopi. Download the file for your platform.
