What does I mean by dual speed RC oscillator? Its mean you can either use RC oscillator as a lower speed or high speed oscillator just by changing the current flow through dual speed RC oscillator. In this post, I will show you how to do it. To design a RC oscillator we need one resistor and one capacitor. But to design a dual speed RC oscillator, we need two resistors and one capacitor. One resistor will be used to change the frequency from low to high and high to low by changing the current flow through the other resistor ....

OVERVIEW OF CHARGE TIME MEASUREMENT UNIT (CTMU) OF PIC MICROCONTROLLERS; the one of the peripheral of PIC microcontroller which is charge time measurement unit (CTMU).It is useful for error applications. The heart of CTMU is the constant current source ranges from 0.55µA,5.5µa and 55µA source and each range are can be trim-able up to +/- 62%.The channels of CTMU works in conjunction with an analog-to-digital converter(ADC). It is also used for high precision time measurement asynchronous to the system such as flow meter and other military applications. There are different types of triggering in CTMU. It can be triggered by external or internal sources like timer1, output compare or software trigger. ....

As some of you know, this term PIC stands for “Peripheral Interface Controller”. And when we try to know about its generations specifically about PIC32, it is cleared to us that constructing on the tradition of Microchip Technology’s domain leading 8 and 16-bit microcontrollers, the 32-bit family offers a large range of products from the industry’s lowest point to highest-point. The architecture of PIC32 is specially designed so to make “passage” from 8-bit and 16-bit architectures seamless and smooth. PIC32 microcontrollers has high performance and high memory. They are especially designed for high performance embedded systems applications. ....

PIC stands for Peripheral Interface Controller. PIC microcontroller was developed by microchip technology in 1993. It was developed for supporting PDP computers to control its peripheral devices and that’s why it was named Peripheral Interface Controller. PIC microcontrollers are of low cost, very fast and easy for the programming and execution of program. Their interfacing with other peripherals is also very easy. PIC Microcontrollers from Microchip Company are divided into 4 large families. ....

Interrupts stops the CPU program from normal execution and ask it to serve first what appear as a interrupt. CPU does not know when these interrupt will happen, so CPU will keep doing its normal execution until interrupt occurs. For example the microcontroller does not know when a user will press a button, so the microcontroller will continue its operation until a interrupt is received. So the CPU keeps on doing its normal job, which may be for example read temperature using LM35 sensor and display on LCD ....

ESP8266 wifi module configurationthis article shows pin configuration of this module and how to connect this module with pic microcontroller. This module works on 3.3V voltage range. So make sure you do not connect more than 5 volt with this module otherwise your module will get damaged. It works on serial communication. ....

The programmer is a debugger system used for software and hardware development of Microchip PIC microcontrollers. The debugger system executes code like an actual device because Instead of using a special debugger chip for emulation it uses a device with built-in emulation circuit. All available features of a given device are accessible interactively, and can be set and modified by the MPLAB IDE interface. ....

Why use MikroC Compiler?It is one of the most popular compilers used for Pic Microcontrollers Programming. There is a number of reasons for its popularity among students and hobbyists. Firstly, it offers a user-friendly interface for beginners. Secondly, Unlike the MPLAB compiler, only a few and simple steps needed to create a new project. Thirdly, when you can create a new project, it automatically includes all resources requires for a select microcontroller. On top of these, it has plenty of built-in libraries for all modules and peripherals of Pic MCUs such as ADC, SPI, I2C, UART, and many others. ....
