摘要
介绍了利用芯片LPC2214的IAP功能实现片内程序的远程下载更新并给出了更新程序的流程图。由于该方法采用的是芯片的内在功能,因此不需要采用商业化的嵌入式操作系统内核并能够使系统本身达到最小化,大大降低了实现的硬件成本,提高了程序下载的可靠性。该技术通过简单修改亦可用于其他具有IAP功能的芯片。
Realization of program remote updating through IAP function of chip LPC2214 is introduced and the flow diagram of updating program is given. Due to utilization of the chip＇ s inherent function, the embedded operating system needn＇ t be adopted, and the system can be minimized. The cost is greatly reduced and the reliability is improved. Simply modified, the technology can also be used in other chips with the same IAP function.
