Python is the language of choice for controlling the Raspberry Pi’s GPIO pins. It seems only natural then that to interact with your Pi over the web it should run a web server able to handle Python CGI scripts. Following the steps below […]
We’re going to use the Raspberry Pi’s SPI bus to control Microchip’s MCP4151 8-bit digital potentiometer. The MCP4151 is an 8 pin SPI device that can be used to programmatically control output voltage. The GPIO pins on the pi run at 3.3 […]
The Raspberry Pi has a Broadcom BCM 2835 chip allowing it to interface with SPI devices on its GPIO pins. There are two chip select pins meaning that the Pi can control two devices simultaneously. P1 Header Pin Function 19 […]
