This work includes, GTP USB (not plus or lite) .

The schematic, photos and PCB have been developed by PICMASTERS based on  some valuable works done before.

This programmer supports pic10F, 12F, 16C, 16F, 18F,24Cxx Eeprom.

Unfortunately, it works with only Winpic800 v.355.  We have succesfully tried it with some pics; PIC18F252, 18F2455, 18F2550,  18F2520, 16F84, 16F628 and 24C32 eeprom.

With an enhanced offer of X-chip series USB chips, it´s possible to immediately choose a type suitable for your application. 

The family of X-Chip series USB chips we introduced to you in the article „New X-chip series will connect you to USB even easier and faster!“. Gradually these USB chips gain still more popularity thanks to a relatively very simple implementation into a target device. It can be said, that a concept of the X-Chip series is based on a direct conversion USB to a chosen serial interface. i.e. to an interface used in our device  (UART, I2C, SPI…), we can choose a suitable chip supporting “our” serial interface. Naturally almost every version is available in various packages. For development and production in smaller quantities it is usually easier to work with packages like SSOP and similar, but for a bigger serial production it´s often more convenient to use a QFN package providing another space saving on a PCB. That´s why we enhance our stable stock offer with the FT230XQ-R chip in the QFN16 package.

For development support, you can find in our store also so called breakout modules providing the simplest way to begin working with X-chips. A novelty in our offer is the UMFT234XF module with the  FT234XD chip. FT234XD is almost identical to FT230X, the difference is only in the package with a less pins count.

In case of interest in any FTDI component, please contact us at info@soselectronic.com.

This little device shows you the CPU-load, how much physical and virtual memory is used. It shows this data per 10% on 3 ledbars. To do so it uses a VCP (Virtual COM Port), so that it can be connected to a PC via a USB connection to receive the data. Collecting the data and sending it to the device is done by a Python script.

The purpose of the project was to create an external USB audio card, which could be able to:
1) serve as usual external USB audio card with headphone/line output and audio line input
2) can transmit the digital audio data at relatively long distance (20m -100m)
3) can receive and process the digital audio data send by the similar card and either transfer it through the USB to the PC, or convert it to analog audio signal
As long distance transfer media was chosen the POF.
A short explanation of the POF technology will be presented:

SpyPow-Render-600x297

Mats continues his challenge of designing one PCB every week. In week 17 he came up with USB Spypow, it displays the actual charge rates of a USB device:

Yesterday I saw the “The Practical Meter” on Kickstarter – a small unit that is placed inline with the USB when charging your phone and shows the actual charging power (in watts) on a row of LEDs. I wanted to have a go at it as well so I did the following last evening.

This is a first in a series of stories called “EEvolution of an idea” showing how a good idea got its start and evolved into a viable product in the electronics industry. I would ask our faithful EDN readers to comment on this series idea and if there is a good positive response which views this as something useful and educational to our readers, then I would like to continue with more interesting and innovative stories like this.

I was recently alerted to an innovative new product called the PortPilot in a comment to an article on EDN.

PortPilot Pro is an inline USB power analyzer, designed by J. Loren Passmore. Passmore describes himself as “an entrepreneur who consults with companies in a variety of industries to envision innovative products and speed their path to market.

USB-to-USB-micro-bridge-1

Florin @ youritronics.com writes:

This is a little project I made recently, I call it USB A to micro USB bridge and it does what the name says: it’s just a bridge between the USB A female connector and the female micro USB. In the middle there is a DIL pin header that allows you to connect or disconnected individually the USB signals. I needed this because recently I started working on a USB project and I wanted to have an easy way to hook up a multimeter for measuring things like voltages or current passing through.

FTDI chip provides really excellent USB chips, that will handle all the USB communication for you with really excellent bandwidth performance. FTDI provide an exhaustive documentation for their cross platform driver. In contrast with the VCP (Virtual Com Port) mode, the D2XX driver allows direct access to the USB device ports in a completely transparent fashion. The Windows drivers are already certified by Windows, so you can just pick your favorite chip from FTDI, and use it in your product without having to worry about time consuming driver development and certification.

All those arguments make FTDI a very good choice if you are willing to launch a cross platform USB based product as we did for ScanaPLUS. However, be warned, there is One Big Problem you will face on Linux platforms. This short post is all about this problem, and the solution we found to overcome it in a nice, transparent and beautiful way.

Babuino is a device as small as a flash drive, and is designed to control any electronic device through your smartphone. We have developed a software package that allows the user to take advantage of babuino without having any background knowledge of programming or electronics.

Babuino intends to interconnect the devices we use in our everyday lives.

Babuino can be connected to a USB port to allow your smartphone to behave as a keyboard or a mouse to control your computer. It’s ideal for wireless presentations, surfing the internet or watching movies from your couch, etc.

Connected to the USB OTG port of your mobile, it allows you to control your phone from your PC which makes it possible to chat on the smartphone as you work without having to touch it, with the convenience of a regular keyboard and mouse.

There is no need to configure anything or install any additional software.

Babuino is an Open Source and Open Hardware project and the device is an arduino compatible board with integrated bluetooth, meaning that enthusiasts can use it as the basis for their own projects involving the control of electronic devices from their smartphones.

The use of Babuino is not restricted to being a keyboard or a mouse, babuino can be used as a webcam, a sound card or any other USB device that receives the data from a smartphone.
