I want to integrate my new Viessmann Vitovalor 300-P fuel cell heating into my home automation. For this, I use the Optolink interface, vcontrold from the openv community, and create my own configuration files from several sources.
I got myself a 10″ multi-touch display from Joy-IT for my Raspberry. I’m quite satified with the display, it has a relatively high resolution, very good display quality, good viewing angle, and touch works very well – the necessary driver is included in Raspbian. Two things that could be better: The backlight is not software-controllable, and the position of the HDMI and USB connectors is not optimal. In the end I want to use the display mounted vertically in a wall, so I included the line
into /boot/config.txt. Unfortunately this only rotates the display, not the touch input, so […]
The Raspberry Pi with Kodi is a versatile media center. Getting it to work with German IPTV in a stable fashion is however somewhat challenging. In this post I outline the necessary steps to set up a XBian based media center, to make it usable on a rather small SD TV screen, to avoid the 30 minutes offset problem with the public German TV stations, to make the channel mappings stable and to control the media center via IR remote control.
The Waveshare/Joy-IT 3.2″ touch display for Raspberry Pi is well suited for embedded applications that require a dynamic but small user interface. This article describes the steps required to get it working with Jessie, X and Python.
The BNO055 is a capable IMU that has on-chip sensor fusion and filtering. Interfacing can be done using I²C and UART. When used with the Raspberry via I²C, you get erroneous measurements because of the I²C clock stretching bug of the Raspberry. Using the UART, results are correct.
