MSP430G2553板LED在P1.0和P1.6,和P1.3连着一个按钮开关,可以对其进行中断编程。

IAR调试msp430时出现警告提示:
The stack plug-n failed to set a breakpoint on "main". The Stack window will not be able to display stack contents. (You can change this setting in the Tool>Options dialog box.)需要进行以下配置:
1. iar->options->linker->output->format;
选择 Debug information for c-SPY选项
2. iar->Tools->options->stack->去掉选项“stack pointer(s) not valid until program reaches”
