PIC16F690 Microcontroller Circuit- How to Drive an LED Display

In this article, we will show how to drive a 7 segment LED Display using a PIC16F690 microcontroller. This PIC16F690 microcontroller chip is actually a part of the PIC2 Starter Kit, so we will actually be using this starter kit to drive the LED Display. A 7 Segment LED Display is an electronic device that contains 8 individual LEDs. Each of the LEDs can either be on or off. Depending on which LEDs are lit d ...

100MHz frequency counter with PIC16F628A – LCD Display

This project shows how to build a very simple yet very useful tool that every DIY enthusiast should have in his lab: a 100MHz+ frequency counter. The schematic is fairly simple and straightforward and uses a PIC16F628A microcontroller for measuring frequency and a high speed comparator for signal amplification and conditioning. The microcontroller uses its internal 4MHz oscillator for the CPU clock. Timer1 ...

100MHz frequency counter with PIC16F628A – LED Display

Couple of weeks ago I purchased from eBay one of these amazingly cheap an useful modules with MAX7219 LED driver and 8 digit LED display. It is ideal for frequency counter project. The problem was the absence of library for PIC microcontrolers. Luckily, I found a great library for Arduino and I reworked it to be compatible with PIC. The schematic of the frequency counter is actually almost the same as the p ...

Open Source 3.2” TFT Smart Display

This project is an open source 3.2″ Smart TFT display board. The board is based on a PIC32 and a 3.2′ TFT with touchscreen (ILI9320 controller, using 16bits PMP). The software has two main parts. One that produces the 2D functions and a GUI with various widgets (buttons, check boxes, sliders etc). Description A new version of 3.2″ TFT Smart Display project can be found here In the beginning, I just wanted t ...

Bicycle Persistence of Vision Light Display — February 2007

In February of 2007 I spent a little while prototyping a board that turns any bicycle wheel into a moving display billboard using a single string of LEDs. The idea was to do something that would be very visible, turn itself on and off automatically, have enough processing power to dynamically generate bike computer style displays, and have enough memory to store full resolution bitmaps. The first revision w ...
