DOS-TSR

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. To expand on the FIFO assignment and implement the FIFO solution on the QWIKFLASH PIC target board and display the FIFOSTATUS as LED indicators. Recall: Flags within a file register called FIFOSTATUS: • Bit 0: FIFO_full • Bit 1: FIFO_empty • Bit 2: attempt_2_read when FIFO_empty • Bit 3: attempt_2_write when FIFO_full

本程序是一个用汇编编的精致的图形时钟，运行时双击clock图标即可，钟表显示的时间为本机系统的时间。　　按b键可扩大画面 ；按s键可缩小画面；按c键可改变颜色；按e键可听音乐；按q键退出本程序.-this program is compiled using a series of intricate graphics clock, double-click the clock running icon, watches showed the time-based system of the machine. By b Bond picture can be expanded; According s keys can narrow picture; By c Bond can change color; By e keys to listen to music; Q keys on the withdrawal procedures.

从键盘输入两个数字(0~7)之间 （1）用16进制表示两个数的和 （2）用四位二进制表示两个数的差，结果一定>=0 （3）用两位十进制表示两个数的积 exemple:-keyboard input from the two figures (0 to 7) between (a) a 16-band, said the number two and (2) with four two binary said the number of poor, the results would certainly gt; = 0 (3) with two decimal number two said the plot example :
