The goal: to learn the CCP module
What do we have: PIC16f628a, the simple devboard + proteus.
I’m going to take a look into the CCP module (Capture/Compare/PWM).
Looking at the name you already can say that you can:
1. Capture
2. Compare
3. Generate PWM pulses
More stuff inside
Continue readingAt that point of time, I did not have a lot of possibilities to buy any commercial development board, so I had to make my own
I wanted to make a small board, not those huge with everything you can imagine, and, perhaps, never going to use. A 3d model shows what I wanted and what I made: 4 buttons + 4 LED hanging on the PORTB. There is also one button and one LED for PORTA. Everything can be disconnected from the microcontroller using the dip switch.
The goal: the same as previous, to get the 1KHz pulse.
What do we have: PIC16f628a, the simple devboard + proteus.
For this particular uC the timer2 module is another 8bits timer, which has some peculiarities.
The goal: to get 1 Hz pulses.
What do we have: PIC16f628a, a handmade devboard, and proteus
Continuing to learn pic microcontrollers, and the timer1 is the next module in our way. Usually, this is a 16bit timer, so it allows to have a larger time frame.
The task: To learn how to use the comparator
Tools: PIC16f628a, proteus
Task: To learn how to control LCD display
Tools: PIC16f628a, LCD 2×16, proteus
Let me try to make the display work in the proteus
Continue readingInterruptions are one of the great things about microcontrollers, if you want to do something fast, reliable, and simple… well, not exactly simple in a programming language sense perhaps, but really simpler from the hardware perspective point of view. So, the main purpose of interruption is to interrupt your main program cycle and do whatever you want in case of that event (a timer has reached the settled time, a button has been pressed, and so on). Here is the picture from the mikroe ebook (www.mikroe.com), just because they really made quite nice pictures and quite a nice manual by the way.
Going further…
Continue readingIt was 2012 year, I was just starting to learn how to work with the PIC microcontrollers, so the code is far away from optimal.
uC: PIC16F628a
Compiler: Hi-TECH PICC
Goal: To connect 7 segment indicator and display numbers from 0 to 9
uC: PIC16F628a
Compiler: Hi-TECH PICC
Goal: To make pulses with frequency 5Hz
Timer TMR0 module frequently used in many applications, it has next useful options:
In that experiment we will make it without using interruptions.
uC: PIC16F628a
Compiler: Hi-TECH PICC
Goal: To make led blink with certain frequency
