一种基于arm的嵌入式linux软件开发jtag烧写工具

基于89C51的六位led秒表汇编语言原程序-89C51-based stopwatch six led the original assembly language program

用89C51串行口外接CD4094移位寄存器扩展8位并行口，8位并行口的每位都接一个发光二极管，要求发光二极管从左到右以一定延迟轮流显示，并不断循环。-Using 89C51 external serial port expansion CD4094 shift register 8-bit parallel port, 8-bit parallel port of each one, all light-emitting diodes, light emitting diodes require a certain delay in rotation from left to right shows, and continue the cycle.

是一个汇编延时程序，适合初学者使用，当P1.0端口输出高电平，即P1.0＝1时，根据发光二极管的单向导电性可知，这时发光二极管L1熄灭；当P1.0端口输出低电平，即P1.0＝0时，发光二极管L1亮；我们可以使用SETB　P1.0指令使P1.0端口输出高电平，使用CLR　P1.0指令使P1.0端口输出低电平。 -Delay is a compilation of procedures, suitable for beginners to use, when the high output port P1.0, P1.0 = 1 that is, when the one-way light-emitting diodes based on conductivity, we can see that this light-emitting diodes L1 extinguished when P1. 0 port output low, that is, P1.0 = 0, the light-emitting diodes L1-liang we can use the command SETB P1.0 port P1.0 output high to enable the use of instructions to enable CLR P1.0 output port P1.0 low.

这是我为电子秤厂商开发的一款液晶软件，直接通过软件设置，可以生产3kg,6kg,15kg,30kg,69kg,100kg,150kg,300kg,600kg,1000kg分度值可达到6000分度，供各位朋友参考!

片机电子钟的计时脉冲基准是由外部晶振的频率经过12分频后提供，采用内部的定时/计数器来实现计时功能。所以，外接晶振频率精确度直接影响电子钟计时的准确性。 -Machine electronic time clock pulse baseline is by an external crystal oscillator frequency, after 12 minutes after the frequency, using an internal timer/counter to achieve the timing function. Therefore, the external crystal frequency accuracy of a direct impact on the accuracy of the electronic time clock.
