然后 driver 也注册到 platform_bus_type 时,就会根据名字进行匹配,从而调用 driver->probe 函数,在 probe 函数里进行 uart_add_one_port 。思路也是很简单的,复杂在 s3c2440 注册 device 之前的工作扯了太多东西。 先秀个最终分析的图: 一、Linux 启动过程回忆 在uboot 启动内核的时候,内核刚刚启动我们就看到...
四、一些jar包提供的方法 //打开设备publicvoidOpenDevice(android.hardware.usb.UsbDevice usbDevice) {/*compiled code*/}//关闭设备publicvoidCloseDevice() {/*compiled code*/}//判断系统是否支持USB HOSTpublicbooleanUsbFeatureSupported() {/*compiled code*/}publicintResumeUsbList() {/*compiled code*/}...

图中的P1就是仿真用的一个串口接口,这个仿真电路要实现与计算机通信功能需要用到其他两个软件,一个是虚拟串口驱动软件,另外一个是串口助手软件,这两个软件在网上都很容易找到。我使用的是Virtual Serial Port Driver和丁丁串口助手,你也可以使用自己熟悉的软件,如果找不到或使用,安装这两个软件有问题可以私信。
the heading Other Software. In the MAX3100-8051 driver code the subroutine UTLK provides driver support for the MAX3100. This code translates from IrDA to RS-232 and back (for demonstration and test purposes), using the 8051's internal UART to talk on the RS-232 side. See code for ...

Hi! I upgraded from win 8.1 to WIn 10 32-bit Enterprise and my CP210x adapter stopped working,gives an exclamation mark and code 31. I have uninstalled driver, downloaded the newest one from your download section but it still doesn´t work. I installed it in another comp...
