Short description of the operation: External circuit converts bass beat of music into pulses. The motor is controlled by them. If theres bass beat recognised then the motor rotates one direction (in full stepping) for a predefined time then stops. If the second beat comes in then it rotates again for the same time and […]
The new PIC18F2550 Project Board was designed as the development platform for student projects. The board features MCU: PIC18F2550 with external xtal, ADC: one channel 0-2.5V sigma-delta converter, Linear Technology LTC2400/LTC2420, 6-channal 10-bit ADC 0-5V, Display: Two connectors for text LCD or GLCD, USB: onchip USB port with type B connector, Power supply: onboard low […]
Electrical The main components of the electrical system were the timing system and the LED control system for 40 LEDs using a single PIC. A schematic of the system is shown below (click for larger view): timing In order to time the display properly to achieve persistence of vision, the PIC needs to record the […]
Simple expansion board for 8051SBC provides easy USB port and graphic LCD interface. I am planning to design the x86 board for some of my application that needs more computing capability. One of the features that I need to add to the x86 board is the USB port. I found the ASIC that enables 8-bit […]
The I²C full master MSSP module is available with a number of PIC MCU models. mikroC PRO for PIC provides library which supports the master I²C mode. Important : Some MCUs have multiple I²C modules. In order to use the desired I²C library routine, simply change the number 1 in the prototype with the […]
Always the right time and date with DCF77 This project make use of a PIC16F628(A) and a DCF77 receiver from Conrad (Orderno. 64 11 38) Optional there is a possibility to connect an electronic gong on it. Click for information about DCF77 on the link underneath: The working from the DCF77 time signal Connect the output from the […]
The ‘One Chip Spinning RGB POV Display’ with conversion software. If you have been on the look out for a project that combines, RGB LED’s, a motor, a microcontroller and a ridiculous amount of hot melt glue, then you have certainly come to the right place. Allow me to introduce the ‘One Chip’ Spinning RGB […]
The mikroC PRO for PIC provides a library for working with 4×4 keypad. The library routines can also be used with 4×1, 4×2, or 4×3 keypad. For connections explanation see schematic at the bottom of this page. External dependencies of Keypad Library The following variable must be defined in all projects using Keypad Library: Description […]
Abstract The objective of this project is to produce a PIC evaluation/development board to be used by future ECPE senior design project teams. Many project implementations call for some sort of microcontroller unit in the final product, and this need can often be met by a simple PIC microcontroller. However, the development of a PIC […]
USB Indoor/Outdoor Thermometer (or, ‘My first USB device’) This is a simple design that demonstrates the USB peripheral on the PIC 18Fs. There are a bunch of examples for the 18F4550 40 pin chips online, this design demonstrates the smaller 18F2550 28 pin version. The PCB uses surface mount parts, but all components are available […]
