error.Automatic traffic control modeBoth uart0 and uart1 of S3C2410 can achieve automatic traffic control through their respective nrts and NCTS signals.In the automatic traffic control (AFC) mode, nrts depends on the status of the acceptor, while NCTS controls the operation of sending disconnections. Specifically, UART sends data in the FIFO only when the NCTS is valid (indicating that the receiver's FIFO is ready to receive data. Before the UART receives data, as long as there are at least 2-

In the first half of this year, I transplanted a Linux driver to a common vimicro camera on the market to an Embedded Development Board. The development environment is: OS: linux2.6.9 Compile: Cross 3.3.2 CPU: Intel PXA270 Camera type: vimicro zc301p + hv7131r The driver source code used is based on the free software spca5xx. Some minor changes were made based on the source code. Record it.

~1, first of all your mobile hard drive to support USB3.0. The words. Just look at the parameters of the hard drive below and you'll know.2, a support USB3.0 data cable. Now the new mobile hard drive standard will be included with one, the distinction method can be referred to in the 3rd Step (2).3, your computer needs to have the USB3.0 interface. How to differentiate the USB3.0 interface? There are actually 2 ways:(1) The simplest and most intuitive way is through the color of the

The Linux USB Gadget device driver can be used to implement some interesting functions. For example, 1. A storage device in an embedded product or a partition of a storage device, it can be used as a USB flash disk by PC. It can easily complete file interaction. This function is widely used in mobile phones, digital cameras, and other products. 2. After an embedd

First of all, from the Internet to search for similar problems, found very common, the heart is more happy. One solution on the web is to change multi-core to a single nucleus, and it does not have a blue screen, but the performance also drops a lot, after all, has entered the multi-core e
