ubuntu加载cp210x驱动

cp210x驱动是USB转串口驱动,嵌入式开发常用。

1、在官网下载cp210x的驱动,根据需求下载相应版本。

查看Ubuntu的Linux版本方法:
s@ubuntu:~$ sudo uname -a

2、下载解压后文件夹内有.c文件和make file文件,在文件夹内打开终端,执行命令s@ubuntu:~$ sudo make 编译make file文件。

3、编译完成后文件夹内会出现.ko文件。然后执行
s@ubuntu:~$ sudo insmod cp210x.ko

4、驱动安装完成。

5、ubuntu上电自动加载驱动模块:
cp210x.ko复制到/lib/modules/.../kernel/drivers/usb/serial文件夹内,
/kernel/drivers/usb/serial文件夹可能会隐藏,可以直接在lib文件夹内搜索serial,就会出现。

6、Windows下直接下载.exe文件,点击安装即可。

This bundle contains a modified CP210x driver for the 4.10.0 kernel (Ubuntu 17.04). It contains: - Support for the CP2102N NOTE: This driver is an example of how to perform GPIO operations within the CP210x driver since the driver on kernel.org does not support GPIO at this time. This driver has only been written and tested on the Linux 3.13.0 kernel on Ubuntu 14.04. This driver is a modified version of the existing driver in the Linux 3.13.0 kernel, which is maintained at kernel.org. It is recommened to use the driver there that matches your specific kernel version: www.kernel.org Build instrutions: Ubuntu: 1. make ( your cp210x driver ) 2. cp cp210x.ko to /lib/modules//kernel/drivers/usb/serial 3. insmod /lib/modules/<kernel-version/kernel/drivers/usb/serial/usbserial.ko 4. insmod cp210x.ko RedHat: 1. yum update kernel* //need to update the kernel first otherwise your header won't match 2. yum install kernel-devel kernel-headers //get the devel and header packages. 3. reboot //your build link should be fixed after your system come back 4. make ( your cp210x driver ) // should be able to build successfully at this point 5. cp cp210x.ko to /lib/modules//kernel/drivers/usb/serial 6a. insmod /lib/modules/<kernel-version/kernel/drivers/usb/serial/usbserial.ko 6. insmod cp210x.ko 7. sudo chmod 666 /dev/ttyUSB0 8. sudo chmod 666 /dev/ttyUSB1 GPIO example: This shows how to use the two IOCTLs to set GPIO state. Build instructions: 1. g++ cp210x_gpio_example.c -o cp210x_gpio_example 2. ./cp210x_gpio_example
