80c51和pc 机通过串行通信程序

80c51和pc 机通过串行通信程序，电平转换用MAX232 (1)单片机端的数据传输程序汇编或者c51 (2)pc机端的vb或者vc编写的通信程序最好是vb (3) pc机用的是COM1 9针端口

SPI UART I2C CAN比较.pdf

Universival Asychronous Receiver/Transmitter（通用异步串行口），UART 是一种较为通用的数据传输的方法（即Start Bit＋Data＋Check＋StopBit），而COM 口中Rx、Tx 的数据格式即为UART。UART 和RS232是两种异步数据传输标准.计算机中的COM1和COM2都是RS232串行通信标准接口。当Uart 接口连到PC 机上时，需要接RS232电平转换电路。

DAC8568驱动程序

This example shows how you can use signal functions in the Visiondebugger to simulate a signal that is coming into one of the analog inputs of the LPC21xx.The Measure example is described in detail in the Getting StartedUser's Guide.The MEASURE example program is available for several targets:Simulator: uVision Simulator for LPC2129MCB2100: Keil MCB2100 evaluation board with ULINK debugger - Application is loaded to internal Flash. - Switch S2 (INT1) is used as GPIO and sampled (jumper positions: J1= off, J7= on) - potentiometer POT1 is sampled as AIN0 (jumper position: J2= on) - serial port COM1 parameters: 9600 baud, no parity, 8-bits, 1 stop bit, flow control noneMCB2130: Keil MCB2130 evaluation board with ULINK debugger - Application is loaded to internal Flash. - Switch S2 (INT1) is used as GPIO and sampled (jumper positions: J1= off, J7= on) - potentiometer POT1 is sampled as AIN1 (jumper position: J2= on) - serial port COM1 parameters: 9600 baud, no parity, 8-bits, 1 stop bit, flow control none
