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.
In early PCs, sufficient performance and purpose could be achieved only by using ISA type devices.
However, as the number of general users who want data speed, better scalability, and ease of use
increased, a new interface (connection) was required, and standard interface methods such as USB and
PCI were enacted. In the case of PCI (Peripheral Component Interconnect), it is designed to be suitable
for processing a large amount of information as a parallel interface method, and in the case of USB
(Universal Serial Bus), serial connection is used to connect more conveniently and facilitate portability.
Both of the above methods use the Plug and Play method so that the user does not need to set the
device. (In the case of the old ISA board, the user directly set the memory, I/O, interrupt, DMA, etc. using
jumpers and switches. -- The problem with this method is that the user must sufficiently recognize the
occurrence of a conflict between the boards and solve it. did.)
In particular, in the case of USB, it can be connected and used while the device (PC) is operating in a
hot-pluggable manner, and in the case of USB2.0, the insufficient data transmission speed can be used
up to 480Mbps, and the number of expansion slots of the mechanical board Regardless, a total of 127
devices can be connected to one host and used. In addition, since it is possible to supply power up to
500mA through a cable, a separate power supply is not required for devices that consume a small
amount of power.
In developing such a USB device (device), the development period can be shortened by providing a
board that can be easily used by developers and can be easily expanded.

[Figure 1-2. A typical USB device (device) internal block diagram]
A normal USB device consists of a “Transceiver” that sends and receives electrical signals inside, a
“Serial Interface Engine” that creates and restores signals with data, and a “Micro-controller” that creates
and uses actual data.
The external interface refers to a mechanical or electrical connection that a user can connect for a
specific purpose of a device. Take a mouse, for example, a button or a wheel.

[Figure 1-4. 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. . In actual data flow, each EndPoint is
a data point or endpoint.
Therefore, this EndPoint connection is called a data pipe.

3-2 Cypress Development kit Installation
The Development Kit provided by Cypress was mainly referenced for board development and
examples, and it is judged that developers will be able to obtain many useful materials and
contents.
“Development kit” can be downloaded from the Cypress website “www.cypress.com” and used.
“Development kit” is a software package with a size of about 60Mbyte, and when it is installed
on a PC, the folder structure is as follows.
[Figure 3-2. Folder structure after installing Cypress Development Kit]
[Reference] In order to install Keil software and separate reference materials, you must select the
installation option as a custom installation rather than the default.
If the installation is successful, you will be able to see that the folder is created on the user's PC
as shown in the figure above.
The Cypress Development Kit includes the Keil compiler and debugger, and can be used freely if
the code size is in the 4K byte range for non-commercial purposes.
