本程序是一个代有带纠错码的串行通信子程序 功能：发送方将数据连发三此，接受方按位进行最大概率纠错。程序返回时，若标志位ERR返回为1，则表示 通信失败；否...

To write assembly code to implement a circular First In First Out (FIFO) buffer in the data memory of PIC18F452 microcontroller, using the microcontroller’s direct addressing mode and indirect addressing mode. This code serves as an assembly program template. For detailed information, refer to the PIC18F452 datasheet, MPLAB IDE user guide, as well as MPASM user guide on the course web page.

首先，分别对8255、8253进行初始化，设置8255为A口、C口输出，设置8253的计数器0为工作模式3；其次，设置IRQ7的中断矢量，使得有IRQ7中断时调用SERVER；再次，调用INIT对计数值初始化；最后，主程序循环等待中断，开始秒表的计时。 2、 INIT子程序-First, the 8255,8253 initialization, set for the 8255 A-C mouth output, set 8253 as the Counter mode 0 3; Second, set up the interruption vector there, make it there interruption call SERVER; Again, call curl_setopt early to count before; Finally, the cycle of waiting for the main program interruption began stopwatch time. 2, curl_setopt Subroutine

此源代码是MSC51项目。这是一个具有自动递增功能的定时器，如果出现电源故障，可以将最后一次计数保存到at89s8254的片上闪存eeprom中。本方案采用七段式液晶显示器代替液晶显示模块。

电子钟的源码，是正确的，可以试试哦！应用于微机原理及接口。-Electronic clock source is correct, try Oh! Microcomputer Principle and Interface applies.

本例载波频率为20KHz，或载波周期为50μs。DSP晶振10MHz，内部4倍频，时钟频率为40MHz，计数周期为25ns。假设调制波频率由外部输入（1～50Hz），并转换成合适的格式（本例为Q4格式）。调制系数M为0～0.9。死区时间1.6μs。最小删除脉宽3μs。 主程序的工作是根据输入的调制波频率计算N、2N和M值。 -Example for the carrier frequency 20KHz, or carrier period is 50μs. DSP crystal 10MHz, internal 4 multiplier, the clock frequency of 40MHz, counting cycle 25ns. Assuming wave frequency modulation by external input (1 ~ 50Hz), and converted into an appropriate format (in this case for Q4 format). Modulation coefficient M is 0 ~ 0.9. Dead time 1.6μs. Delete the smallest pulse width 3μs. The work of the main program is based on input frequency modulation wave calculation of N, 2N and M values.
