parallel port driver

After reading the serial port driver for two days, I finally watched the driver of a great god. I wanted to write a blog by myself and suddenly found that it was also the content of the great god, so repost it. Address: http://blog.csdn.net/wulong117/article/details/7378265The serial port

Nbsp; in general, when compiling the kernel, there are two methods to choose the device driver: one is to directly compile it into the kernel, and the other is to hook up the module. If the CS8900 NIC driver is mounted as a module, the init_module function is the entry; if it is directly compiled into the kernel, then the cs89x0_probe function In general, when compiling the kernel, there are two methods to

I have been busy with other things recently. I haven't touched ECOs for a long time. These two days are a bit blank. I have to write a serial driver to play with it and verify the interrupted call of ECOs. LZ spent two days writing this driver, and encountered a few disgusting problems. later it was found that the previous Foundation was not well prepared. Fortunately, it was solved. Although ECOs has alre

/*Name: C51io Port analog i²c bus driver AT24C16Description: About EEPROM, that is, the AT24C16 here is a special form of flash memory, but its capacity is generally less. More suitable for storing small amounts of data. The AT24C16 communication interface is the standard i²c communication, which means that we need to manipulate the EEPROM device according to the I²C communication protocol. About the variou

Bought a root USB to RS232 serial line, Pl2303 chip. The sellers and the official all said does not support WIN8, but I do not believe in Win7 can use in the win8/8.1 will not be used up.The official latest version of the v1.9.0 driver description said that does not support the win 8/8.1, after the attempt does not support. Hardware can be identified but cannot be started (error code 10, yellow exclamation mark).The latest version of No, then look for

2440 external serial port driver debugging (Author: wogoyixikexie @ gliet) The previous week, the serial port MDD has been transplanted to BSP, and the three serial ports are already normal, but the external serial ports can only be sent and cannot be received. Later, I found that the external serial port was interrupt

You do not need to download the USB driver in Linux.ProgramTo re-mount the USB device, enter the following in the terminal window:Sudo modprobe ftdi_sio vendor = 0x0403 Product = 0xa6d0 First, set the program.

Most of the current laptops are no longer equipped with serial ports, and are pre-installed with Microsoft's latest Vista operating system. However, in daily development work, you may encounter serial programming through USB-to-serial data lines in a notebook without a serial port. Through the online search of the solution provided by the Vista system, the USB to serial port data line

Throughout the c file, I feel like the real core code: S3c2410_gpio_setpin (led_table [I],! CMD ); The core of this sentence is s3c2410_gpio_setpin. Baidu has come to give a detailed explanation. It provides exceptionally powerful guidance on understanding the address ing of the 24x0 series Development Board in arm-Linux.
