ST套件上0-99秒计时，比较准的！(由网友wonderfulsf提供) ST套件上0-99秒计时，比较准的！ 这是我学习PIC完成的第一个程序烧在了ST套件上不错,0-99秒计时 如果用MPLAB模拟,用stopwach计时非常准 ST套件上0-99秒表程序,根据原0-99键控程序上改写的,初学练习-ST package on time 0-99 seconds, more accurate! (Wonderfulsf provided by users) ST package on time 0-99 seconds, more accurate! This is my PIC study completed the first procedure to burn in the ST package on good ,0-99 seconds time if MPLAB simulation, with very stopwach time on quasi-ST Suite 0-99 stopwatch program, according to the original 0-99 keying procedures on rewriting, and learning exercises
