3.3 Board Driver Installation
(Notice) All test made a Windows2000 Professional with bases, we are having finished
the final test at Windows XP.
Execute “Device Manager”at My Computer -> Properties -> Hardware -> Device
Manager window.
[Figure 3.3 Select “My computer”->”Properties”]
[Figure 3.4 “Device Manager” window]

Figure 3.4 shows that “Device Manager”execution window. You can check all USB
device connection at your PC. Currently not yet connect “USB-EK01”, it is not
marked.
[Figure 3.5 USB-EK01 Connection]
The USB-EK01 is connected to PC through USB cable after jumper setting like
above red circle. The reason of using jumper is that an address of EEPROM(24LC64)
is able to recognize it at AN2131. AN2131 is having function of EEPROM information
to connect I2C port can select a lot of booting option when Power On Booting.
Usable EEPROM is same as the following table to a board booting option. Refer to
“I2C Boot Loader”of AN2131 manual for special information.
Bytes EEPROM A2 A1 A0
16 24LC00 N/A N/A N/A
128 24LC01 0 0 0
256 24LC02 0 0 0
4K 24LC32 0 0 1
8K 24LC64 0 0 1
When it is connected to USB cable, “New Hardware Search Wizard”execute
automatically, you can check the USB device at “Device Manager”.
It don’t require another driver because of Cypress Development Kit was installed.
Figure 3.6 will be shown after completely installation. An EEPROM information of board
is as follows at default (when first purchase).
0000h: B0 47 05 80 00 00 00 (Refer to file 2100.iic at Cypress)
That is, Using VID(Vender ID) = 0x547, PID(Product ID)=0x80 in EEPROM will be
registered to PC in an USB device.

[Figure 3.6 A board was registered with default to PC]
If the jumper don’t connect, the screen is as follows. The way that you can confirm,
after remove jumper, reset switch of a board is “ON/OFF”or reconnect a USB cable
after remove. For more specific information, refer to “Chapter 4.3 Booting Option”.
[Figure 3.7 A board was registered to PC without recognition EEPROM]

You confirm to register to PC like figure 3.6 that rebooting a board after connection
jumper. After that, “EZ-USB Control Panel(EzMr.exe)”utility which given Cypress
Development Kit perform.
[Figure 3.8 EZ-USB Control Panel]
(Notice) When development a product at Cypress, Usable utility is searchable in
“Cypress\USB \Bin”and “Cypress\USB\Util”.
The execution screen of “EZ-USB Control Panel(EzMr.exe)”is like figure 3.9.
If connection doesn’t work a device, the error message will be marked.

For more usage method of Control Panel, refer to “EZ-USB Contents and tutorial.pdf”
at Cypress.
From now, the board installs to a “DAQ system”development board so that
registration works to PC. Basically all test above setting even is possible, a driver of
DAQ system shall be install in case of the debugging that used Keil software in order to
put a necessary image to a board. The Vender ID which used to installation is “FFFF”,
this is not the ID which it was registered and I used it as I select temporary.
When Power On Reset, it will act to any contents and a report judges the contents as
reading the first byte of EEPROM connected to I2C.
If the first byte is not ‘0xB0’or ‘0xB2’, it is performed with default as judge it to
things without EEPROM. (Vender ID 0x0547, Product ID 2131).
It shall modify contents of EEPROM so that recognition gets a board done to a
development board of DAQ system. (Vender ID 0xFFFF, Product ID 0001)
For more detailed egarding boot option, refer to “Chapter 4.3 Booting Option”.
A way to modify of EEPROM is as follows.
When press “EEPROM”button at EZ-USB Control Panel, “file dialogue box”appears.
When it is selected a file “Sample.eep”of Program\EPROM_IMG folder in CDROM and
press open button, will be changed a contents of EEPROM.
[Figure 3.10 “sample.eep”for changing EEPROM’s information]

The contents that it was changed are as follows.
0000h: B0 FF FF 01 00 00 00, in other words, VID is 0xFFFF and PID is 0x0001.
When finished EEPROM writing, press reset switch or remove and re-connect the USB
cable. The board gets re-registration at PC.
And then, above ID doesn’t currently get registration at PC, “New Hardware Search
wizard”will be open and display like figure 3.11.

[Figure 3.14 Driver Selection window]
After select a file “daqusbw2k.inf”in Software\Driver folder at CDROM, press
“Confirm”button and will finish driver installation. If installation finish, press “finish”
button and disappear window like figure 3.15.
[Figure 3.15 Driver Installation Completion window]
If installation finish, you confirm a registration state that you perform “regedit.exe”at
Window. All contents registered to OS(Windows) that is saving to PC, stored contents
and revised program that can edit it is an registry editor(regedit.exe).

At display of “Start/Execution”, write “regedit”and press “Confirm”button.
[Figure 3.16 “Start/Execution”Window]
[Figure 3.17 Registry Editor Window]
If a registry editor is used most a case, it use to confirm and erase a value of key.
(Notice)If a key value want erase, it can erase it at “Security”items as it perform
regedit32 after having exchanged use authority in case of Windows2000.
This concludes all installation procedure of test and development.

4. USB-EK01 Description
4.1 USB-EK001 Concept
A basic concept of USB-EK001 made it so that a hardware and software engineer
developed it so as to easily make various tests, and an engineer of various levels can
utilize it. In other words, a person to touch a embedded program and hardware for the
first time, the person whom he/she is familiar with other microcontroller, and want to
practice 8051 programming, embedded USB board Firmware development, USB device
driver development for PC, Application Programming through using USB interface at PC,
and we made it to use debugging practice step by step when embedded firmware
development. User can test all functions only using the USB-EK01 board, all
development tools can use it to free or evaluation type. Also, you can easily use because
you don’t need special power supply.
Now I will explain main connection and functions of USB-EK01 board.

14 JP7 Address/Data/ I/O extension connector
15 P1 RS232C connection, it can
use a debugging and
general communication to maximum 115200bps.
Figure 4.2 shows USB-EK01 functional block diagram, we put emphasis to
expansibility and a design was performed around the main AN2131QC chip. All Data,
Address, I/O can exchange a board expansion, can connect external device through
RS232C, USB, I2C interface.
We made it so as there was a LED and Tact switch, and to be able to test the simple
external input/output test automatically, and don’t need an external power supply
because basically power supply get from USB cable.

4.2 Memory Map
4.2.1 USB-EK01(8051) Memory Map
Figure 4.3 shows general 8051 Microcontroller memory structure.
The 8051 is equipped with a memory which display inside dotted line, it is
different from memory which it use external data/address bus.

[Figure 4.3 8051 Memory Map]
An area to be possible to direct addressing methods in the inside is from 0x00 to
0x7F, address from 0x00 to 0x1F is used to the register bank(0 ~ 3) which it is used
when it operate at CPU. BDATA is from 0x20 to 0x2F, is able to the addressing in a
bit unit. From 0x80 to 0xFF of address is SFR(Special Function Register) area when
access to direct addressing methods, is general data area(IDATA) when access to
indirect addressing methods. The SFR area has the registers for CPU calculation and
for control surrounding I/O area.
8051 has separate space of the data memory area(XDATA) and the program
memory area(CODE), each area accessing classify to signal line of “RD/WR”and
“PSEN”. The program memory (CODE) can include in chip oneself, each
manufacturing company is able to choose various selection until the maximum 64K
Byte at 4K Byte. A mainly flash memory uses in now, user prefer that it is able to
exchange a structure of program. At this time, an input state of “EA”pin decides
whether or not there is to use an external memory whether or not there is to use
inner memory.

4.2.2 USB-EK01(AN2131) Memory Map
Cypress의AN2131 which have a core of 8051 microcontroller is same memory
structure of 8051 internal memory. But, other point got separate RAM(8K Byte) in
the chip inside and use to program and data memory.
Also, the RAM can use a EndPoint buffer in case of USB data transmission,
therefore, the driver write a program in this RAM area when first Power ON reset
and can make it so that a program operates that user wanted it.
The USB-EK01 board doesn’t have special external memory (RAM/ROM), it is
same structure of memory map like AN2131 chip.
