About This project implements a basic calculator using a Raspberry Pi Pico microcontroller, a 4x4 Keypad Module, and an I2C 16x2 LCD Display. The calculator allows users to perform addition, ...

Based on RPi.GPIO, it writes instructions to a 16x2 LCD module through Raspberry Pi's GPIO pins directly. This is not for interfacing an I2C LCD. Since it's not for realtime applications, the clock ...

While the Raspberry Pi has very good support for an I2C bus, a lot of very cool chips – including the in system programmer for just about every ATtiny and ATmega microcontroller – use an SPI ...

[Tech2077] is one of the lucky ones who already got his hands on a Raspberry Pi. He’s been looking into different interface options with the GPIO header and just posted a guide to using an HD… ...
