Interfacing the Microchip PIC18F Microcontroller Master Synchronous Serial Port (MSSP) to various I2C Devices

The Inter-Integrated Circuit or I2C (read as I square C) bus has been introduced in 1980 by Philips, and has become a de-facto world standard for data exchange between Microcontroller and various devices such as temperature sensor, ADC (analog to digital converter), DAC (digital to analog converter), I/O expander, EEPROM, and many more. With more than thousand different IC devices have been manufactured wit ...

Embedded System for Automatic Washing Machine using Microchip PIC18F Series Microcontroller

The design uses the PIC18F series microcontroller. All the control functionalities of the system are built around this. Upgradeability is the unique feature of this system. Control card hardware and software allows the manufacturer to add or remove the features as per customer requirement and model. Thus once the whole system is designed it is very economic in large quantity production. Single-phase motor i ...

Open Source Framework for USB Generic HID devices based on the PIC18F and Windows

Introduction If you've dabbled with PIC18F microcontrollers and the USB Generic HID standard before (perhaps you've even tried my Building a PIC18F USB device project) then you will have noticed that there is a lot of complexity in supporting USB on both the PIC18F and the Windows host-side of things. Getting beyond the basic steps of reading a switch and flashing an LED (how many projects have you built to ...

Building a PIC18F USB device

Introduction I get a number of emails every month asking about creating USB devices using the PIC18F microcontroller. After looking at projects such as my Atari Joystick USB Adaptor and C64 VICE Front-End there seems to be a demand for more information on how to 'hack your own'. In this article I will show how to breadboard a simple USB generic HID device, creating the PIC18F firmware and finally creating t ...

Using Digole 12864ZW LCD with PIC18F

Digole 12864ZW is a 128×64 pixels graphic LCD that can be found at attractive prices and this is why it started appearing in projects across the web. It is based on ST7920 chip which is not so well known and to me it wasn’t the easiest to work with.' The documentation for this display can be found here. You can find a couple of examples on how to use this display and some attempts on making a library and mo ...

Real Time Clock (RTC) Interfacing PIC18F

Introduction to RTC: Real time clock also referred as RTC is an important device or integrated circuit which will keep the track of current time. RTC is mainly used in computers, mainframes servers and embedded applications (mobile phone, tablets, organizers, PDA etc). The main function of the RTC is to keep the track of time of the device even though it is in off or turned off state. The best example is yo ...

Getting started with PIC18F Microcontrollers

After writing quite a bit of experimental tutorials on PIC16F series of microcontrollers, I thought of moving forward to the enhanced-range family of PIC microcontrollers, the PIC18F, which was introduced by Microchip in late 90s. Although PIC16F series are excellent general purpose microcontrollers, certain limitations have emerged, such as, they have limited program and data memory, their stack size is sm ...

Reverse Engineering to Emulate Ink Cartridges for a Epson Printer using PIC18F

Reverse Engineering to Emulate Ink Cartridges for a Epson Printer For the past two years, I’ve been planning to build myself a 3D printer from some old Inkjet printers that I had collected over the years. But not until two weeks ago had I actually started to work on it. The 3D printer I want to made uses a ink jets to print a chemical onto a building platform. The building platform goes down as a new layer ...
