Timer 1, how to make a reliable Real Time Clock in 8-bit PIC
Measuring seconds comes really handy in many circuits. Executing tasks with demanding precision, such as a real time clock, requires an external oscillator (often called 'crystal') of 32,768Hz. Such procedure…
Timer 0 as External Counter in 8-bit PIC microcontroller
In the previous post, Timer 0 as an Internal Counter was explained and configured to use the internal clock (i.e. the oscillator) to count a defined quantity of time. However,…
Timer 0, a simple Counter in 8-bit PIC you need to know
Instead of creating software to count seconds or pulses, a specific hardware was created to deal with this necessity called 'timers'. There is a bunch of different kinds of timers…
Interrupt sources in 8-bit PIC and how to quickly attend them
Interruption by hardware takes care of emergent situations that requires attention as soon as possible. The code is interrupted, the situation is attended, and finally is taken back to previous…
Code Template, an easy guide for PIC Microcontrollers in C
As your programs get more complex and advanced, the necessity for order comes urgently. Classifying the whole code into sections according to topic and purpose is essential to maintain it…
Hello World with 8-bit PIC microcontroller
For the purpose of this post, I'm going to write a very simple code for the demonstration, which will just light an LED. It could be considered a "Hello World"…
Setting up PWM on a PIC Microcontroller
About PWM. Hello everyone, Juditova here! The Pulse Modulation Width (PWM) helps any microcontroller tremendously on most control tasks. You see, PWM makes the connected device to believe its connected…
