The ShiftRegister74HC595 Arduino Library simplifies shift registers usage. It allows you to set single pins of your shift register either high or low, just like normal Arduino pins. It thereby removes the overhead of shifting out bytes that were created […]
In late 2017, small groups of our class were given the task to delve into the assembly language and write a program for the 8051 microcontroller, as part of the Low-Level Programming lecture. This post documents the project MOV is Turing-Complete: 4-bit […]
The ShiftRegister PWM Library enables usage of shift register pins as pulse-width modulated (PWM) pins. Instead of setting them to either high or low, the library lets the user set them to up to 256 PWM-levels. This post serves as […]
The widely used Arduino IDE offers many easy-to-use functions, one of them is void digitalWrite(uint8_t pin, uint8_t val) . It sets one of the microcontroller’s pins to either high or low and serves well in many cases. However, it has a really poor performance, […]
This post is a tutorial on how to get started on programming your Arduino in Assembly or C/C++. In order to follow you need a Windows machine and a microcontroller programmer like the Atmel-ICE.
