arm9 s3c2440与zlg7290的接口程序。在 ADS1.2下通过编译并能运行。-arm9 s3c2440 zlg7290 interface with the process. ADS1.2 through the compiler and will run.

单片机复位电路的可靠性设计复位电路的基本功能是 系统上电时提供复位信号直至系统电源稳定后撤销复位信号为可靠起 见电源稳定后还要经一定的延时才撤销复位信号以防电源开关或电源插头分-合过程中引起的抖动而影 响复位-MCU reset circuit reliability design of the circuit" s basic function is to reset the system power-on reset signal until the system is to provide stable power to withdraw the sake of the reset signal as a reliable power supply stable even after a certain delay to revoke a reset signal to prevent the power switch or Power plug points- combined jitter caused in the course affected by reset

应用背景此代码是使用RS485芯片接受DMX512解码器传输数据。关键技术这背后的技术是让更多的串行通道DMX512。

spi驱动，设置每个寄存器，以及ioremap的用法，连接收发两个引脚进行测试-spi-driven, each register set, and ioremap use, two connecting pin transceiver test

verilog编写，将I2C串行数据转化为并行数据的功能模块，类似于PCF8574芯片的功能。以后不用买另外的芯片就可以直接将并行数据连到I2C总线上了-Verilog prepared to I2C serial data into parallel data of the function modules, similar to the function of PCF8574 chip. After the chips do not have to buy another can be connected directly to the parallel data to the I2C bus on the
