用89C51 控制nRf 905收发 C源代码-with 89C51 905 transceiver control nRf C source code

利用单片机AT89S51与adc0809设计一个数字电压表，能够测量0－5V之间的直流电压值，四位数码显示，但要求使用的元器件数目最少-AT89S51 with adc0809 use of single-chip design of a digital voltage meter, capable of measuring between 0-5V DC voltage value, four digital display, but requires the use of minimum number of components

基于ARM7的U盘程序开发代码,可以-ARM7-based U-procedure code, can see the

该程序比较好用容易修改，是一个单片机应用类的一个很好的程序。-err

FIQ有FIQ_PWM、FIQ_TMA和FIQ_TMB三个中断源,当定时器A或B计满溢出时产生中断请求信号TA_TIMEOUT_INT或TA_TIMEOUT_INT,CPU响应后进入中断执行相应的子程序控制二极管发光。A口的低四位接LED灯，B口的低四位接LED灯.-FIQ has FIQ_PWM, FIQ_TMA and FIQ_TMB three interrupt sources, when the timer A or B when the expiration overflow interrupt request signal TA_TIMEOUT_INT or TA_TIMEOUT_INT, CPU response after interruption of the implementation of the corresponding subprogram control light-emitting diodes. A low population of four LED lights then, B I take the low four LED lights.
