本文详细介绍了把μC/OS-Ⅱ移植到ATMEL公司的8位微控制器ATmega128上的全过程。所谓移植，就是使一个实时内核能在某个微处理器或微控制器上运行。在移植之前，希望读者能熟悉所用微处理器和C编译器的特点。-This paper introduces the mu C/OS- Ⅱ ATMEL company to 8-bit microcontrollers ATmega128 on process. Alleged graft, is to make a real-time kernel can in a microprocessor or micro controller. In the hope that readers can before transplantation, familiar with use microprocessor and C compiler characteristics.
