PIC Microcontroller Communication with RS232 Bus – XC8

image-292
RS232 serial communication is one of the oldest communication where data is sent or received one bit at a time. This protocol can easily be used to communicate between a PC and various devices supporting this type of protocol like PIC microcontrollers, GPS, GSM modem etc. While other interfaces like Ethernet, FireWire, and USB all send data as a serial stream, the term "serial port" usually identifies hardware more or less compliant to the RS-232 standard, intended to interface with a modem or with a similar communication device. The Universal Asynchronous Receiver/Transmitter (UART) controller is the key component of the serial communications between a device and a PC or between devices. UART is also a common integrated feature in most microcontrollers today which is useful for communicating serial data (text, numbers, etc.) to your PC. In this article we're going to learn how to use the RS232 communication with MPLAB XC8 Compiler using the PIC18F Peripheral Library and MPLAB Code Configurator.

PIC Microcontroller Communication with I²C Bus – XC8

image-287
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

PIC Microcontroller Communication with SPI Bus – XC8

image-283
The SPI or Serial Peripheral Interface is a synchronous serial communication and allows multiple devices to communicate with a micocontroller(s). There are many devices that support the SPI protocol and can easily communicate with a microcontroller via SPI: A/D converters, D/A converters, SD Cards, DS1306 Real Time Clocks, MAX7219 serial display drivers, 25LC256 Serial EEPROM, etc. The devices don't have to be identical as long as they support SPI protocol. In this article we are going to configure the SPI Peripheral with MPLAB Code Configurator and PIC18F Peripheral Library.

Introduction to Graphical User Interface (GUI) for Microcontrollers

image-108
A graphical user interface (GUI) is one of the ways to interface between your microcontroller and a personal computer (PC) operated by a human with a mouse or a keyboard. It is always easy and require less skills to operate a device from a visual representations of the workspace (GUI) by simply clicking a mouse or using a keyboard rather than a command line. GUI can also be used to interface with other external devices located in different places. There are a lot of kinds software which can be use to design a GUI platform, the choice will usually depend on personnel preferences, software capabilities and the operating systems (Windows, Linux, Mac...). Among the popular ones we have Microsoft Visual Basic, Microsoft C#, Labview, Matlab etc.

USB Communication with PIC Microcontroller

Many computers especially portable ones do not have a serial port (COM Port) anymore. When a connection to a Personal Computer (PC) is required, a USB is the choice. The Universal Serial Bus (USB) is the widely used interface in electronic consumer products today. Most of electronic devices have at least one USB port on them, this include PCs, cameras, GPS devices, printers and so on. Some PIC18 microcontrollers support USB interface directly. 16bits (PIC24) and 32-bits (PIC32) pic microcontrollers have also an embedded USB interface. In this article we will learn how a communication between a host PC and a microcontroller can be achieved with a USB bus.

USB Human Interface Device Communication with PIC Microcontroller – MikroC

image-332
The HID device class code is "0x03, this class is used for devices operated by human, devices like keyboard, mouse, joystick and so forth. The advantage of HID devices is that, they don't require to install drivers, in most modern operating systems, the device will be detected without any problem. The USB HID protocol allows a personal computer to recognize a USB HID connected to it without the need to create a device driver, this is the same like when you connect a USB optical mouse or a USB keyboard you don't need to install drivers for that. Windows operating system will load the required drivers, all that is needed is to to supply the PC with a descriptor file containing some information from the device like Vendor ID (VID), Product ID (PID), Manufacture name and so forth. MikroC Pro for PIC provides USB HID library that make it easy for a host device to communicate with a slave device on a USB bus.
