How to interface LED with Microchip’s PIC microcontroller? How to connect LEDs to a PIC microcontroller? LED interfacing is the stepping stone for microcontroller development. This is a simple embedded program for PIC 16F877A to interface LEDs, suitable for beginners who wish to study basics of embedded microcontroller programming. The program is developed through Micro […]
During the last months, a new WS2812 alternative appeared on the market: The SK6812. I finally managed to get my hands on some of them to take a closer look. In most aspects these devices are basically clones of the WS2812. What is interesting however, is that the manufacturer came up with a couple of

Microchip has included a new power building block in a microcontroller aimed at LED lighting. Called the PIC16(L)F1769, the family has the first PICs to offer two independent closed-loop channels. The firm has steadily been introducing power control peripheral blocks over the last three years – so-called ‘core independent peripherals (CIPs), including for example its

Usually We need embedded systems inside devices, particularly the so-called intelligent devices, to communicate with a command/control/administrative center. Typical such situations could be a remote security camera that can send you video clips when queried, an embedded system that can send status when checked through a web browser or a vending machine that is capable

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

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
