In this series I'll be connecting the PCA9555D 32-bit GPIO expander board to an Arduino micro-controller. First we started out simple with counting from 0 to 255 in binary on eight LEDs. SeePart 1for technical information and getting started. Here in part two we will connect a 4X4 keyp...

The recent announcement of the latest release of the Raspberry Pi Desktop x86 image alongside Raspbian Stretch for Raspberry Pi included mention of a GPIO expander tool, which was followed up by another blog post explaining how it works and how to use it. Since it uses pigpio to control the...

(1)有些key controller芯片、codec或者PMU的芯片会提供I/O port (2)有些专用的IO expander芯片可以扩展16个或者32个GPIO 从硬件角度看,这些IO和SOC提供的那些IO完全不同,CPU和IO expander是通过I2C(也有可能是SPI等其他类型的bus)连接的,在这种情况下,访问这些SOC之外的GPIO需要I2C的操作,而控制SOC上的GPIO只需...
The GPIO expander method allows you to boot the Pi Zero over USB from the PC, without an SD card. Your PC sends the required boot firmware to the Pi over the USB cable, launching a mini version of Raspberry Pi OS and booting it in RAM. The OS then starts the pigpio daemon, allowin...
