cc2642芯片

请问使用cc2642芯片自己设计开发时，如果想自己分配所有资源I/O资源 ，是不是不能使用官方提供开发套件sdk，官方sdk可以初始化所有30个DIO口吗？我没法初始化使用led.button.uart所占DIO口。

Alvin Chen：

以simple_peripheral为例：

int main()

{

 /* Register Application callback to trap asserts raised in the Stack */

 RegisterAssertCback(AssertHandler);

 Board_initGeneral();

只初始化部分IO，当然可以初始化所有IO看你的自己使用情况去添加：
