【Avnet | NXP FRDM-MCXN947试用活动】+新建工程点灯测试
本次从无到有新建MCXN947的keil工程测试。首先打开keil新建工程，选择MCXN947器件。!(https://www.eefocus.com/forum/data/attachment/forum/202411/17/113246mlj7f9k7xv9n1gzt.png)
然后在RTE中选择启动文件。

再就是选择需要的外设驱动。

这里我选择了必须的外设和基础的GPIO以及串口打印框架。!(https://www.eefocus.com/forum/data/attachment/forum/202411/17/133435ao5tpzo89pezq796.png)
然后复制SDK中的board初始化文件到新工程内。

设置编译优化选项和头文件路劲。参考SDK工程配置设置。

参考SDK内容需要加入如下代码

SDK中添加了如下代码：
!(https://www.eefocus.com/forum/data/attachment/forum/202411/17/134322kzhczy9orxelh3nk.png)
```
void SystemInitHook(void)
{
/* enable the flash cache LPCAC */
SYSCON->LPCAC_CTRL &= ~SYSCON_LPCAC_CTRL_DIS_LPCAC_MASK;
/* Disable aGDET trigger the CHIP_RESET */
ITRC0->OUT_SEL = (ITRC0->OUT_SEL & ~ITRC_OUTX_SEL_OUTX_SELY_OUT_SEL_IN9_SELn_MASK) | (ITRC_OUTX_SEL_OUTX_SELY_OUT_SEL_IN9_SELn(0x2));
ITRC0->OUT_SEL = (ITRC0->OUT_SEL & ~ITRC_OUTX_SEL_OUTX_SELY_OUT_SEL_IN9_SELn_MASK) | (ITRC_OUTX_SEL_OUTX_SELY_OUT_SEL_IN9_SELn(0x2));
/* Disable aGDET interrupt and reset */
SPC0->ACTIVE_CFG |= SPC_ACTIVE_CFG_GLITCH_DETECT_DISABLE_MASK;
SPC0->VDD_CORE_GLITCH_DETECT_SC &= ~SPC_VDD_CORE_GLITCH_DETECT_SC_LOCK_MASK;
SPC0->VDD_CORE_GLITCH_DETECT_SC = 0x3C;
SPC0->VDD_CORE_GLITCH_DETECT_SC |= SPC_VDD_CORE_GLITCH_DETECT_SC_LOCK_MASK;
/* Disable dGDET trigger the CHIP_RESET */
ITRC0->OUT_SEL = (ITRC0->OUT_SEL & ~ ITRC_OUTX_SEL_OUTX_SELY_OUT_SEL_IN0_SELn_MASK) | (ITRC_OUTX_SEL_OUTX_SELY_OUT_SEL_IN0_SELn(0x2));
ITRC0->OUT_SEL = (ITRC0->OUT_SEL & ~ ITRC_OUTX_SEL_OUTX_SELY_OUT_SEL_IN0_SELn_MASK) | (ITRC_OUTX_SEL_OUTX_SELY_OUT_SEL_IN0_SELn(0x2));
GDET0->GDET_ENABLE1 = 0;
GDET1->GDET_ENABLE1 = 0;
}
```
最后就是main函数点灯了。

最终编译成功:

烧录到开发板就可以看到灯亮了。
