控制道路指示灯的汇编代码-road indicator compiled code

用仿真的方法实现超宽带信号的产生，先产生一个带宽确定的矩形波行，将其调制到射频频率上去 -Simulation method used to achieve ultra-wideband signal generation, to produce a bandwidth of the rectangular-wave line to determine its frequency modulation up to RF

,片选接到p1.5 复位端 p1.4 中断端接到 int0 82c250工作在斜率模式下 ，RS 接51k电阻到地。 2，SJA1000与82C250的接口，逻辑上为SJA1000输出0（显性位），表现为低点平输出给82C250，则82C250输出 差分的低电平。SJA1000输出1（隐性位），表现为高电平或悬空输出给82C250，则82C250输出悬空状态。 3,周立功的中SJA_BCANCONF.ASM中对输出控制寄存器 的TX0的输出 极性的位的定义不对。 还有里面定义有接收错误标志码，不知道何时用。-, The election received a P1.5-chip client p1.4 interrupt reset int0 82c250 client received in the slope mode, RS then 51k resistor to ground. 2, SJA1000 with the 82C250 interface, logic for SJA1000 Output 0 (dominant bit), showing low level output to the 82C250, while the low-level differential output 82C250. SJA1000 Output 1 (recessive), and the performance of the output is high or left vacant to the 82C250, the vacant state 82C250 output. 3, Zhou Ligong in the SJA_BCANCONF.ASM of output control register TX0 output polarity bit the definition of wrong. Inside the definition also has to receive error flag code, I do not know when to use.

控制APIC的汇编源程序-control APIC compilation source

利用汇编语言实现的一个打字练习程序，程序界面为典型的Dos窗口，当字符从窗口顶端掉下来后，如果按键与该字符相同，字符变为红色，在打字结束后，给出打字的统计结果，在打字过程中按ESC可退出程序 -The use of assembly language to achieve a typing practice program, the program interface for the typical Dos window, when the characters fall from the top window, if the button with the same characters, the character turns red, in the typing after the end of typing results is given , in the typing process by pressing ESC to exit

用8251实现串行口异步通信，自发自收，波特率1200bps。采用查询方式发送与接收。从键盘输入发送字符。发送与接收的字符均在屏幕上显示。按esc键返回dos-Achieved with the 8251 serial asynchronous communication, spontaneous self-income, the baud rate 1200bps. Way to send and receive using queries. To send characters from the keyboard. Send and receive characters are displayed on the screen. Press esc key to return to dos
