LCD (Liquid Crystal Display) I2C (Inter-Integrated Circuit) is an easy-to-use display module, which can make displaying text easier. Using this module can reduce difficulties faced by makers, so they ...

/* Example code to drive a 16x2 LCD panel via a I2C bridge chip (e.g. PCF8574) NOTE: The panel must be capable of being driven at 3.3v NOT 5v. The Pico GPIO (and therefore I2C) cannot be used at 5v.

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 bus.

We’ve gotten used to the GPIO-available functions of Raspberry Pi computers remaining largely the same over the years, which is why it might have flown a little bit under the radar: the Raspberry Pi 4 ...

This small article describes how to build your own I2C slave device using a PIC microcontroller, and how to control it with the Raspberry Pi. This approach combines the power of the microcontroller ...

The Waveshare 1.69-inch IPS touch LCD is a 1.69-inch rounded display with 240×280 resolution and a 262K color range. The display driver (ST7789V2) and touch controller (CST816T) are integrated ...
