One of the most enjoyable part of being an electronics person is creating your own gadgets and using them in daily life. In this article, we are building one of those with the help of SoloPCB design tools, a digital desk clock with temperature display feature. The brain of the circuit is a Microchip […]
In this article, our author Mithun has developed a 0 – 99 min counter using PIC microcontroller 16F628A. So basically this is a digital count down timer ideal for engineering and diploma students for their project requirements. We have given complete circuit diagram of the digital count down timer along with full source code. In
In this article, we have come up with a new PIC micro controller project. Our author Mithun has created a Digital Voltmeter Circuit using PIC16F73A and multiplexed 7 segment displays. The circuit is well explained with diagrams and the source code (written in Embedded C language) is available for download. Â If you have any doubts
Our world relies upon Communication. In today’s world, we can make almost anything communicate with everything! How about communication between a PC and a microcontroller (PIC)? Now, before making a PC and a PIC talk, if you are not sure about USART module and LCD, here are some good articles about them to just refresh:
Introduction to MPLAB IDE – What is it and how to install it? The above link takes you to the article about introduction to MPLAB IDE, in case if you have missed it. Having installed MPLAB IDE and one or more compiler suite, this article describes how to compile a program and extract the .hex
Similar to Atmel’s AVR studio, Microchip MPLAB is a feature rich IDE which integrates compiler tool-chains into the IDE itself and also supports proprietary programming devices and debuggers for the Microchip’s Controller family. Just if you have a microchip programmer such as Pickit2 or ICD2, then just plug it to the computer and all you
Timer Module: A Timer is a simple module included along with almost most of the microcontrollers. A timer can be used as a timer/counter. The size of the timer varies from controller to controller. The PIC16F84A has one 8 bit timer module. The very basic operation of a timer is to count and nothing else!.
Having known about the byte oriented file register operation, only two categories are remaining – the bit oriented file register operations and the control operations. Bit-oriented file register operations: Here these instructions are used when a single bit needs to be affected/changed/checked. There are only four bit-oriented instruction for the 16F84A Mnemonics & Operands Description
The instruction set of PIC16F84A has 35 instructions [The controller “understands” 35 words].These instructions are otherwise called Mnemonics. While introducing about the PIC16F84A till the hello world program, Â 7 instructions are introduced to you which were, BSF – bit set f BCF- bit clear f MOVLW – move literal value to W-register MOVWF – move
The previous posts about PIC16F84A explained about controlling the GPIO(General Purpose I/O) pins of the IC. Previously laid circuits explained only about how to switch on or off an LED. You just simply set the desired pin to output and then send a high/low signal to switch on/off the LED. Now, in this post, let
I hope everyone who read the post about programming the PIC16F84A will now be savvy with downloading the program to the controller, and also check the working of the controller. In the previous post, we discussed about producing an output (switching on an led) using PIC16F84A. Here, I will tell you how to work with
