Page 4: Introduction
USB-EK01 User‟s Manual 1. Introduction After IBM's PC (Personal Computer) was announced in 1981, the PC has penetrated deeply into not only industry but also individual life. Perhaps, imagining everyday life without a computer is difficult these days. The reason why the PC was able to develop so rapidly is because many devices (devices) were designed and utilized for their respective purposes by opening standardized interfaces and architectures to the public. - Page 5 [Figure 1-3] above shows the connection of a normal USB device to the Host (PC). If you look at USB specification 1.1 here, the device is divided into low speed (1.5Mbps) and full speed (12Mbps). -up) through resistance. USB-EK01 is a device that supports full speed.

USB Device Logical Concept] As can be seen from the figure above, when looking at a USB device from a logical point of view (programming), one device can have multiple configurations, and a configuration can be divided into multiple interfaces, and an interface can have multiple endpoints.

Since Cypress Development Kit is pre-installed, a separate driver is not required.
- Page 13 USB-EK01 User‟s Manual [Figure 3-7. The screen where the board is registered in the PC without EEPROM recognition] Then, connect the jumper again, reboot the board, and check whether the board is registered in the PC as shown in [Figure 3-7]. If confirmed, run “EZ-USB Control Panel (EzMr.exe)”, a utility provided by Cypress Development Kit.
- Page 14 For detailed usage of Control Panel, refer to “EZ-USB Contents and tutorial.pdf” provided by Cypress. Then, from now on, install the board so that it is registered in the PC as a “DAQ system” development board. All basic tests are possible with the above settings, but in order to put the images needed for debugging using Keil software on the board, the driver of the DAQ system must be installed.

All the contents registered in the OS (Windows) on the PC are stored in the registry, and the program that can check and edit/edit the stored contents is the registry editor (regedit.exe).
- Page 19 USB-EK01 User‟s Manual [Figure 3-17. Registry Editor Window] The most frequently used case of the registry editor is to check or delete the previously registered Key value.

In addition, since there is no need for a separate power supply, it is easy to use. I will explain the main connections and functions of the USB-EK01 board using the board outline below. - Page 21 RS232C Connection, It can be used for debugging and general communication at up to 115200bps. The figure below shows the functional block diagram of USB-EK01, and it was designed focusing on scalability with the main chip, AN2131QC. All Data, Address, and I/O are made available for board expansion, and can be connected to external devices through RS232C, USB, and I2C interfaces.

USB data. Therefore, when the first power ON reset, the driver writes a program to this RAM area so that a desired program can be operated. The USB-EK01 board has the same memory map structure as the AN2131 chip because it does not use a separate external memory (RAM/ROM). -
Page 24: Ik01(Expansion Board) Memory Map
USB-EK01 User‟s Manual 4-2-3 USB-IK01(Expansion Board) Memory Map The USB-EK01 board uses RAM and ROM to expand external memory so that it can be used for applications with large program size and data memory size. In case of ROM, Flash memory is used to eliminate the need for a separate ROM writer, LED switch (DIP/Tact) is added for peripheral I/O testing, and a chip that can expand I/O through I2C interface. - Page 25 0x1B40 0x0000 [Figure 4-7.
