This article presents the first of a six-part series of learning the peripheral functions of a microcontroller that is the GPIO (General-purpose Input/Output). It discusses the important peripheral, ...

The MCP23017, a 16-bit I2C GPIO expander, has always been a tasty chip. With 16 GPIOs addressable over I2C, proper push/pull outputs, software-enabled pull-ups, eight addresses, maskable interrupts ...

This paper provides a complete solution to the GPIO Verification for any SoC. GPIO interface is available in every ASIC. To avoid duplicate efforts and (save) time to verify the GPIO interface, we ...

This application note introduces the user to the 1-Wire® communication protocol and describes how a 1-Wire device can be interfaced to the PIC® microcontrollers. 1-Wire protocol is a registered trade ...

An automotive body control module (BCM) is an electronic control unit (ECU) that manages a wide range of vehicle comfort, convenience, and lighting functions, including the central locking system, ...

Over the years, we’ve seen some modern microcontrollers turn out to be 5V-tolerant – now, RP2040 joins the crowd. Half a year ago, when we covered an ISA card based on a Pi Pico, [Eben Upton] left a ...

This paper discusses about a low cost, portable, reusable platform established to ease the in-system power-up behaviour evaluation of MCU. This flexible platform is able to generate ramp-up signals at ...
