用PIC16F877实现的基于Hoarder board的C源程序，希望对各位做嵌入式开发的朋友有所帮助。...

61A的IRQ4中断有三个中断源：1KHz、2Kz和4KHz,每一个中断分别控制与IOA0-IOA1、IOA2-IOA3和IOA4-IOA7相连的LED灯。-61A of the IRQ4 interrupt has three interrupt sources: 1KHz, 2Kz and 4KHz, each interruption of the respective control and IOA0-IOA1, IOA2-IOA3 and IOA4-IOA7 connected to LED lights.

ISP for STR73X 默认情况下, bank0 是映射到地址0x00. 考虑到,IAP程序需存储在bank1,而用户程序需存储在bank0. 因此须使用CAPS工具,将bank1映射到地址0x00. 另外, 在IAP程序运行期间,必须在执行用户程序跳转之前,通过程序将bank0重映射到地址0x00(注:IAP程序已经实现了bank0重映射到地址0x00,用户不需要自己来编写代码).-ISP for STR73X default, bank0 is mapped to address 0x00. Taking into account, IAP process is stored in the bank1, while the user program to be stored in bank0. It is necessary to use the CAPS tool bank1 mapped to address 0x00. In addition, IAP procedure during operation must be in the implementation of user program before Jump through the procedure will bank0 re-mapped to address 0x00 (Note: IAP program has achieved bank0 re-mapped to address 0x00, the user does not need to write their own code).
