LED、LCD数码显示是电子技术中一种不可缺少的技术。用PIC单片机控制技术实现LED和LCD的数码显示,不仅电路简单,而且制作成本很低。用一片PIC单片机,采用动态扫描技术,可以实现多位数的LED或LCD数码显示,从而更能发挥PIC单片机的优势。在这里,笔者用两位LED数码管计数(最大99)和1片PIC16F84A说明在数显方面,采用动态扫描,编辑其源程序的方法。这里虽然仅用了LED两位数字的显示,但其介绍的方法很
LED, LCD digital display is an indispensable technology in electronic technology. With PIC microcontroller control technology to achieve LED and LCD digital display, not only the circuit is simple, but the production cost is very low. With a PIC microcontroller, dynamic scanning technology, you can achieve multi-digit LED or LCD digital display, which can give full play to the advantages of PIC microcontroller. Here, I use two LED digital tube count (up to 99) and a PIC16F84A Description digital display, the use of dynamic scanning, editing the source code. Although only two digits of LED display here, but its introduction is very way
