Description:

Up-to-date USB developing kit for D12 chips. To serve as a helper for newbie, main board, illustrations, C source codes for CPU (AT89S52) control, source codes of drivers, source codes of testing programs, etc, are all included in this suite of experimental developing kit. It’s well known by those who developed applications with USB, that the major hindrance to newbie are the the programming of the firmware, which is the program of controlling CPU, and the programming of the drivers. Including the firmware and the source codes of drivers, this kit, however, helps you to enter the gate of USB developing palace as easy as turning your hand over, so long as you can understand those C source codes. When developing your own USB device, you don’t have to code from scratch. Instead, a bit of modification to the programs we provide will just make your project finished with ease. USB D12 is such a developing kit that helps you make full use of Philips’ PDISUBD12 (D12) features. Not only can we learn how it works, from this kit, but we can also have further ideas of how to transform device to USB device. Plus, D12 developing testing applications, applet USB drive and a few example codes of firmware are also included in this suite of developing kit.

Consisted of D12 and its interface, the microcontroller AT89S52, this simply designed kit is intended to present USB’s distinct features. Philips’ PDIUSBD12 can implement all fuctions of USB device and it has 8-bit parallel data bus for microcontroller, which is a member in the 8051 family. With the attached applet, you can operate this kit in 3 modes, printing, scanning and circulatory returning.

With DMA data transferring mode, D12 is a cost-effective, high-performanced, microprocessor-based USB interface device. This suite of kit enables you to thoroughly evaluate the performance and feature of the device, and quickly prepares you with the knowledge of how to change existing non-USB device (such as large memory of digital camera, or scanner) into USB device.

Package item list:

Content included in CD-ROM
Firmware of the kit and its entire source codes and project files.
Drivers and their source codes
Applications and their source codes
Schematic and related illustrations of D12
inf files for drive installation

Main features:

1. Communication between 51 series SCM and PC.

2. Codes of firmware and D12 interface program in both C and assembly language, for user’s pleasure. (C codes are aimed for the study and maintenance of the program)

3．You can learn how to design software and hardware with USB and single-chip microcomputer, as long as you have some basic knowledge in single-chip microcomputer, C programming language and fundamental PC theory. And if you manage to understand the documents and diagrams we offer, and comprehend the source codes, you will be able to develop your own USB interface on this kit, and then transplant them into your own designs.

4. Including circuit designing, program coding, driver coding, testing program coding, it’ll take like 5 or 7 or nearly 1 year’s time to develop USB from the ground up, because there’re too many things related to USB. Without source codes and circuit diagram as references, the progress will be time-wasting and difficult, not to mention the probability of losing business opportunities. However, the source codes, which you can easily modify, circuit diagram and experimental USB board, can dramatically shorten your developing cycle.

5. All the scource code we offer in this USB developing kit can be freely modified. Useful for your development.

6. No more developing tools needed when developing USB. A single-chip microcomputer simulator will make the developing easier.

7. It’s well known by those who developed applications with USB, that the major hindrance to newbie are the the programming of the firmware, which is the program of controlling CPU, and the programming of the drivers. Including the firmware and the source codes of drivers, this kit, however, helps you to enter the gate of USB developing palace as easy as turning your hand over, so long as you can understand those C source codes. When developing your own USB device, you don’t have to code from scratch. Instead, a bit of modification to the programs we provide will just make your project finished with ease.

Demos:
Below are pictures that are taken when I did some USB experiments. Hope it’ll give you more insight into USB interface developing.
It’s an experiment to turn on the LED and nixie tube as well as control the relay and buzzer via USB.
First off, connect developing board to computer by USB cable. After hooking it up, the new USB device will show up in Windows Device Manager.

The screen snap in which no USB board gets hooked up.

The picture in which USB board has been successfully connected to computer. “Philips PDIUSBD12 SMART Evaluation Board” shows up.

Now, the green LED on the board has been turned on, indicating a successful connection.

Then, let’s change some of the firmware’s codes and 上位机’s codes to implement the specific functions we need. Little modification needed, only a couple of lines of codes need to be changed.

In the below picture, we have already turned on 8 LEDs through USB, and have the first LED tube presenting the digital 8. Of course the hummer from the buzzer along with the sound from the relay can also be heard. Up to this point, I bet you have already realized the convenience and advantage that developing D12 USB program has. As long as you know single-chip microcomputer, you can develop USB device.

Now , Let’s begin make a new USB PDIUSBD12 Evaluation Kit .

This is new version, RED PCB.

First use solder to weld PDIUSBD12 chip.

Hardware Description

    1, working voltage 2.4-3.3 V, working current mA@3.3V, 25, 40 mA@2.4V

    2, launch frequency range 67 MHZ, 128 MHZ, launch frequency covers the whole FM frequencies, through the key regulation.

    3, launch frequency interval 0.5 MHz, can actually reach 0.1 Hz ac, but considering the receiving device, we set to 0.5 MHz, such as a need to amend stepping value, can contact us.

    4, volume is small and exquisite, is equal to half the smaller chewing gum.

    5, use a wire as the antenna, the length of the antenna according to actual listening environment can be appropriately increase or decrease forehead!!!!!

    6, and the use of digital regulation method, frequency cycle regulation, need not worry frequency range beyond receive.

    7, launch piece and FM radio in testing and using FM, no distance limit, far to 50 meters, nearly to a few centimeters, won’t because the distance from screaming. Nearly cry

    8, launch frequency stability accurate, automatic display can capture a, use more convenient.

    9, launch for a few centimeters distance to 50 meters, commonly keep out words in 30 meters or so. And the environment around antenna also has much higher height, launch, steel and concrete structures around the less effect and the launch distance. Of course, the best open place!!!!!
