Analog to Digital converters allow analog continuous voltages to be converted into a discreet digital numbers inside the PIC as the PIC can only process digital numbers. This can enable a PIC to be connected to analog sensors such as temperature sensors, pressure sensors, humidity sensors, optical sensors, and power sensors. Any sensor which can generate a voltage between 0V and a maximum 5V can be used. If the output voltage is higher than 5V, a method to step it down should be used such as a voltage divider with resistors.
The I²C or Inter-Integrated Circuit is a serial communication and allows multiple devices to communicate with a micocontroller(s) over only two wires. The devices don't have to be identical as long as they support I²C protocol. In our illustration, the first device with address 1 is a digital temperature sensor, the second one is a real time clock and the third one is a serial LCD display and the bus could carry on even more devices. Communication takes place from the master (PIC) to the individual selected slave only as shown in this illustration. Configuration with PIC18F Peripheral Libraries and MPLAB Code configurator are discussed in this article
Interrupts are one of the most powerful features of PIC Microcontrollers, interrupts make it possible to create applications that can respond to external stimulus in real time. An interrupt is basically an event that requires the microcontroller to stop normal program execution and then to jump to execute a program code related to the event causing the interrupt. An interrupt requires immediate attention, only once the microcontroller will finish executing the interrupt code, then it can go back to continue with the main program. The interrupt code is called Interrupt Service Routine (ISR) or Interrupt Handler. In this article we're gonna learn how to implement Interrupts using Interrupt registers and with MPLAB Code Configurator..
A memory card (also called a flash memory card) is a solid-state electronic data storage device used for storing digital information. They are commonly used in many electronic devices, including digital cameras, mobile phones, laptop computers, MP3 players and also in many applications where a large amount of data has to be stored either once or continuously like in data loggers. Memory cards are small, re-writable and are able to retain data without power. In this article we will learn how to interface an SD Card with a PIC Microcontroller with SPI bus to write and read to/from an SD card with MPLAB XC8 and MPLAB Code Configurator.
Ethernet is the leading wired standard for networking as it enables to connect a very large number of computers, microcontrollers and other computer-based equipment to one another. With just a network switch, many different devices can easily communicate with one another with Ethernet, allowing different devices and equipment to be accessed remotely and this also provides a cost-effective and reliable means of remote control and monitoring. For microcontrollers which don't have an integrated Ethernet peripheral, Microchip offers a serial Ethernet chip that can easily be used by any microcontroller with an SPI interface to provide Ethernet capability to the application. The ENC28J60 is a popular 28-pin serial Ethernet chip, 10BASE-T stand alone Ethernet Controller with SPI interface, on board MAC & PHY, 8 Kbytes of Buffer RAM and an SPI serial interface. In this article we will learn how to use the ENC28J60 Ethernet controller with Microchip TCP/IP Lite Stack and MPLAB Code Configurator.
TC74 is an I2C Digital Temperature sensor form Microchip. TC74 is a serially accessible digital temperature sensor particularly suited for low cost and small form-factor applications. Temperature data is converted from the on-board thermal sensing element and made available as an 8-bit digital word. In this tutorial we are going to learn how to use MPLAB Code Configurator to read temperature from the TC74 temperature sensor and display it on an LCD
