一个4510的BIOS,已经测试通过了,在里面添加了基于USB的烧写方法...

视觉暂留，编程从一个I/O口输出一扫频信号，驱动一支LED灯闪动，频率范围为10HZ~99HZ，扫描时间为30秒，在LED闪动期间观察，一旦发现无法识别LED灯闪动时，按下按键K1，立即停止输出，并将此时的信号频率显示在数码管上，该信号的周期为测试者的视觉暂留时间。-Persistence of vision, programming from an I/O port outputs a sweep signal to drive an LED light flashing, the frequency range of 10HZ ~ 99HZ, scan time of 30 seconds, the LED flashing during the observation, once found it impossible to identify the LED lights flashing, press the key K1, immediate cessation of the output, and at this time the signal frequency displayed on the digital control on the test cycle of the signal" s persistence of vision time.

PIC单片机无符号数运算子程序,可以直接调用!-PIC unsigned few Operational subroutine can directly call!

通过键盘控制，选择max262不同的工作方式（低通，高通，带通）。用‘+’，‘-’及数字键来控制不同的中心频率，该文件就有详细的正确的C51程序及部分仿真电路。该源代码经过实际验证。-max262--Programmable Filtering

这是我用汇编语言编写的计时器程序，通过计算机发命令开始倒计时，其中也有其他功能，但主要是倒计时，比较好用，这是个小程序，穿上来了表心意-This is the language I used compilation prepared by the timer procedures, through the computer started the countdown orders, which also has other functions, but the countdown is more convenient, it is a small program to put on the table liking
