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…

Need to add additional CSS:
/* Make individual posts full-width */
.singular.page .hentry {padding:1em;}
.singular .entry-header,
.singular .entry-content,
.singular footer.entry-meta,
.singular #comments-title {

}It 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
An article dedicated to learn and develop some basic approaches related to Discrete Fourier Transform.
As it known from Fourier series, any signal can be represented as a sum of different simple signals, which basically allow as to simplify a computation and makes possible FFT transformation.

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.
