CP210xManufacturing Library for CP210x
--------------------------------------
Silicon Labs provides a source package for building
the CP210xManufacturing library for linux.
Uncompressing the source package
--------------------------------
$ tar -xf cp210xmanufacturing_1.0.tar.gz
Source Package Contents
-----------------------
- /common/ - OS abstraction
- /cp210xmanufacturing/include/ - Header files that declare the interface for the CP210xManufacturing library
- /cp210xmanufacturing/src/ - Source files for the manufacturing library
- /Makefile/ - Used to create the library.
- /doc/ - library documentation and rules file.
Dependencies
------------
1. libusb-1.0
On Ubuntu:
$ sudo apt-get install libusb-1.0-0-dev
2. g++
On Ubuntu:
$ sudo apt-get install g++
Building libcp210xmanufacturing
-------------------------------
To create the CP210x manufacturing library for the current architecture (either x86_32 or x86_64):
$ make
To install it at the default location (/usr/local):
$ sudo make install
Configure Your System to Allow libusb to Access Your Device
-----------------------------------------------------------
CP210xManufacturing uses libusb-1.0 to communicate with the CP210x devices over
USB. In order for CP210xManufacturing to recognize your device, you must first
copy a udev file to /etc/udev/rules.d/. This udev file will automatically
enable read and write permissions for a device with the specified USB vendor
ID. Unplug and replug your device after copying a udev file for the permissions
to take effect. On some systems, it may be necessary to reboot the machine
before the new rules are applied.
CP2101 (VID: 0x10c4 PID: 0xea60):
- Copy SiliconLabs.rules to /etc/udev/rules.d/
Other:
- Modify an existing udev rules file for the required vendor ID
SUBSYSTEM=="usb", ATTRS{idVendor}=="10c4", MODE="0666"
SUBSYSTEM=="usb_device", ATTRS{idVendor}=="10c4", MODE="0666"
- or - (optionally add a required product ID)
SUBSYSTEM=="usb", ATTRS{idVendor}=="10c4", ATTRS{idProduct}=="ea80", MODE="0666"
SUBSYSTEM=="usb_device", ATTRS{idVendor}=="10c4", ATTRS{idProduct}=="ea80", MODE="0666"
- SiliconLabs.rules does not specify the product ID and will therefore allow
read/write access to all Silicon Labs USB devices with the Silicon Labs VID (0x10c4).
The product ID is optional and will further restrict which devices the rules file
will affect.
