0 – Introduction In a previous article we learnt how to use a keypad with the Esp32 using the Arduino libraries, in this one, we will go a step lower and use a Arduino Nano with no Arduino libraries. A perfect fit for our ‘Baremetal’ series. For this article I will use a 4 by […]

0 – Introduction In previous posts we already made a working Chip8 Emulator both on Ubuntu and on a Esp32 with the help of the Arduino libs and U8g2. In this article though, we will ditch every help we previously had and implement everything from scratch, as it has become tradition in our ‘Baremetal Arduino’

0 – Introduction A lot of sensors, screens and even flash memory use SPI as the way to communicate between them and the micro controller. With so many options of what to connect, it would be a mistake to not implement SPI in your baremetal project. In today’s article, we will use what you learned

0 – Introduction In the world of microcontrollers, PWM is used to communicate with some motors, or even other microcontrollers, one example is, the servos and ESC in a RC car, it is also a great way to create a DAC (Digital to Analog Converter). In today’s article, you will learn how to use PWM

0 – Introduction While using an arduino there are a lot of things that require timings, communications like SPI and I2C or PWM but, besides communications, maybe you want to make an animation with LEDs, or measure time between events, either way, having access to a timer is very important. The ATMega328p inside the arduino
