首先第一件事当然是收集资料
1、官网(http://mcuxpresso.nxp.com/en/welcome)下载了SDK,有IAR,keil 的,我以上传至百度网盘,有需要的可下载
2、万利网站提供的资料（百度网盘）
3、keil 54000 系列 pack （百度网盘）

百度网盘链接：    https://pan.baidu.com/s/1nvODEqP

PS：发现用联通的4G卡上官网速度杆杆的，能500K/s的下载速度。
      我发现固件不更新虚拟串口也能输出。

然后上电测试
   插上USB连上电脑（板子CN1口），出现的是板子预装的演示程序，按按键led9会亮，有声音事led8会亮，串口输出检测的温度

上电的板子

串口输出

点灯

1、没有安装LPC 54000 pack 安装包的需先安装（以上传至百度网盘）

2、打开下载的SDK的 led例程，路径如图
LED例程1.png

3、查看LPC54114板子led IO口
在万利提供的资料有PDF的原理图
LED例程2.png

4、按照原理中的IO修改例程

BOARD_InitPins(); 函数配置led0~led7 IO

主函数如下

void Led(uint32_t port, uint32_t pin, uint32_t output)
{
gpio_pin_config_t led_config = {
kGPIO_DigitalOutput, 0,
};
GPIO_PinInit(GPIO, port, pin, &led_config); //IO¿ÚÅäÖÃÊä³ö
GPIO_WritePinOutput(GPIO, port, pin, output);
}
int main(void)
{
uint32_t port_state = 0;
/* Define the init structure for the output LED pin*/
gpio_pin_config_t led_config = {
kGPIO_DigitalOutput, 0,
};
/* Board pin, clock, debug console init */
/* attach 12 MHz clock to FLEXCOMM0 (debug console) */
CLOCK_AttachClk(BOARD_DEBUG_UART_CLK_ATTACH);
/* enable clock for GPIO*/

CLOCK_EnableClock(kCLOCK_Gpio1);
BOARD_InitPins();
BOARD_BootClockFROHF48M();
BOARD_InitDebugConsole();
/* Print a note to terminal. */
PRINTF("\r\n GPIO Driver example\r\n");
PRINTF("\r\n The LED is taking turns to shine.\r\n");
/* Init output LED GPIO. */
Led(0,15,1);//led0~led3 ¸ßµçÆ½µãÁÁ
Led(0,19,1);
Led(0,21,1);
Led(0,22,1);

{
