How to work with External (Hardware) Interrupts of PIC18F4550
Posted on: 22 Jun 2017
Interrupts are special events that require immediate attention. They cause the processor to cease the running task to serve a special task for which the interrupt event had occurred. After the special task is over, the processor resumes performing the original task. The processor can also serve these events by polling method. But polling is […]
FTDI Chip adds EVE Screen Designer
Posted on: 21 Jun 2017
Bringing more comprehensive support to its Embedded Video Engine (EVE) product offering, FTDI Chip introduces EVE Screen Designer – which is available to download for free. Suitable for use with Windows 7 and above, the development suite enables the creation of advanced human machine interfaces (HMIs), via EVE’s object-oriented approach, without any understanding of EVE […]

AquaCont – Aquarium Control using pic microcontroller
Posted on: 21 Jun 2017
The AquaCont is an electronic system witch permits to manage and to monitor most of the parameters of all the electrics devices that can be found in a aquarium. The PIC18F4520 used to realize it, combines a real time clock and a temperature sensor in order to control 8 relays. The system main characteristics are: […]
How to interface 16×2 LCD in 4-bit mode with PIC18F4550
Posted on: 20 Jun 2017
The 16×2 character LCD can work in two modes, namely, 8-bit and 4-bit. These modes basically correspond to the number of data pins used in interfacing LCD. 8-bit mode uses all the data lines and has been explained in LCD interfacing with PIC18F4550. In 4-bit mode, only four data pins of LCD are connected to […]
Heart rate measurement from fingertip
Posted on: 20 Jun 2017
Heart rate measurement indicates the soundness of the human cardiovascular system. This project demonstrates a technique to measure the heart rate by sensing the variation of the blood volume inside a finger artery, which is caused by the pumping action of the heart. It consists of an infrared LED that transmits an IR signal through the fingertip […]
