Cypress Semiconductor Corporation

|
CyUSB Serial library.
|
|
=========================================================================================
|
|
Pre-requisite:
|
|
1. libusb-1.0.9 is required for compilation and functioning of the APIs in the library.
|
|
2. GNU Make and the GCC tool-chain are used for the build process.
|
|
|
|
Installation steps:
|
|
|
|
1.cd to the main directory where the library source files are extracted and goto ./linux/library
|
|
|
|
2.Type 'sudo make'.
|
|
|
|
2.This will generate shared library libcyusbserial.so.1 and its soft link libcyusbserial.so.
|
|
Both of them will be copied/installed to /usr/local/lib.
|
|
|
|
3.Go to ./linux/testUtility (I2C/SPI test utility program) and type 'sudo make'.
|
|
This will generate CyUSBSerialTestUtility binary (Refer to README in testUtility folder).
|
|
|
|
4.User can launch the application and test the communication with Cypress USB-Serial DVk in vendor mode.
|
|
|
|
Changing USB device node permission:
|
|
|
|
By default the USB device node created in linux do not have read/write permission
|
|
for normal user. In order to make the USB device node accessable, copy 90-cyusb.rules
|
|
which is inside the library folder of release package to /etc/udev/rules.d folder (Default VID mentioned is Cypress VID
|
|
which is 0x4B4, if VID is changed then update it in ATTR{idVendor} section of rules file).
|
|
|
|
*** IMPORTANT:
|
|
Some distribution of linux have libusb (older version) as part of their package. Uninstall
|
|
the older version and update it with libusb-1.0.9.
|
|
|
|
**Note:
|
|
Refer to ./common/doc/CyUSBSerial API documentation.pdf for description of all
|
|
the vendor mode APIs. The header file of the library is in ./common/header/CyUSBSerial.h.
