ow that we listen to MP3s, and watch XVIDs or x264s, a computer is the entertainment center in at least one room of most homes. Unless you have a special HTPC, though, you’re probably stuck using the keyboard to pause, change the volume, and fast-forward through annoying Mythbusters recaps. PC remote control receivers range from ancient …

The synchronizer ensures a contact-free, optical synchronization of external photographic flashguns. The triggering of the external flash is derived from embedded flashes of a camera. It can be used for both digital and “analogous” cameras or for a remote synchronization of the actual flash units. Its use is optimal especially with digital cameras (DC), where …

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 …
Have you ever wondered how your PC and phones keep track of time even when the device is turned OFF? Well there is a Real Time Clock (RTC) that is kept powered even is the device is turned OFF. Once the device is turned ON and connected to the internet the device connects to a …
Introduction USB is very common interface today. If you look around, many of devices today comes with a USB port. Computers, printers, routers, usb keys, etc. All this devices have a USB controller inside. These devices can be divided in two groups: USB Host (like a computer, routers, modern LCD TV’s); USB Device (like flash …
This page introduces a minimal firmware that implements a USB Virtual Serial Port for Microchip PIC18F4550 processor. The code has been optimized to use minimal amout of memory (both Flash and RAM) and tuned to work well with the Free SDCC C-compiler. The code size is less than 2500 bytes and it requires about 230 …
