For many makers, a project idea sometime may take a very long time to materialised. This project for creating a STM32G070-based PalpTop handheld took me almost a year, starting from the initial idea, to making the final PCB, and still not 100% completed yet. Continue reading "Build a PalmTop handheld with STM32G070"
On previous article, I wrote an Arduino sketch for interfacing LCD 5110 display module with Arduino, it is not an Arduino library that can be distributed and share with others yet. In this article, I will explain how to create an Arduino library in 6 easy steps. Continue reading "How to create Arduino Library from Arduino Sketch"
In this article, I will briefly explain on how to create a Python class library to interface with LCD 5110 display module and shares the common APIs with the Arduino LCD5110 library that I previously created. Continue reading "How to use LCD 5110 (PCD 8544) with Raspberry Pi"
LCD 5110 (a.k.a. Nokia 5110 or PCD8544) display is a commonly available LCD module with SPI interface, by writing our own LCD driver based on its data sheet, we could learn a lot about how the LCD module works and how to write SPI program and save a lot of SRAM memory.
