Standard release for lighting LED-driver interface

The Module-Driver Interface Special Interest Group (MD-SIG) has released its specification for a universal electrical interface between LED lighting modules and their power supplies. The standard has the support of Osram, Panasonic, Philips and Tridonic. Called LEDset1 edition1.0, it is a three wire interface (see diagram): power, ‘Iset’ and a return for both. The specification also allows for separate retu ...

2-wire LCD interface using PIC16CF84

Alphanumeric LCD displays have become very popular for microcontroller applications because they can add a lot to a project in a variety of different ways. A text message giving the user instructions as well as feedback can make the application seem much more "professional" and easy to use. I like to use LCD's to help debug applications, with breakpoints set to display variable and I/O conditions and they a ...

PIC USB HID (Human Interface Device) Interfacing

For long time, UART is the only and best way to interface with PC. It is easy to adapt and handle. Though some devices (like: GSM modem etc.) have UART on themselves, but for interfacing with PC, there is only one thing now and that is USB Introduction The purpose of this article is to explain how to interface a PIC microcontroller to a PC via the USB port. Although the concepts are universal, the examples ...

LCD interface with Microcontroller PIC: Beginner’s guide using pic microcontoller

How to interface LCD (Liquid Crystal Display) display module to PIC microcontroller? LCD is a passive component, that is it does not make any light but just modifies the light passing through it for alphanumeric displays. LCD is exclusively manufactured to be used with microcontrollers, which means that it cannot be triggered by usual IC circuits. This embedded program shows how to connect PIC to LCD displa ...

PIC18F452 to PC USB 2.0 interface with FT245BM

Here is an example of how to interface a PIC18F452 to a PC  via the USB port. The windows-pc (98, Me, 2000, XP, 2003) runs a program (C# application, Microsoft Visual Studio .NET 2003) to communicate with the USB interface, which transfers data to and from the PIC18F452. Many thanks to FTDI to deliver royalty-free drivers (FTD2XX.dll) and to KOPF to develop the needed library (AID.dll) All parts are availab ...

Serial to PIC Interface using PIC Microcontroller

One of the first things I like to do when creating a new project is to get the I/O working. This helps in debugging the code as I write it. What about projects that do not have I/O? This device sneeks both input and output from your computer (terminal program) to the PIC using just one pin. In order for this circuit to work, you need to set either DTR (pin 4) or RTS (pin 7) to positive voltage. Turning on C ...
