先从这里下载资料【HT32 Cortex-M 系列懒人包 (整合包)】：https://bbs.21ic.com/icview-3205412-1-1.html找到例程文件夹的example\GPIO\InputOutput
双击_CreateProject.bat创建响应工程
完成后打开工程，修改主函数，实现两个板载LED的闪烁效果：
- int main(void)
- {
- CKCU_Configuration(); /* System Related configuration */
- /* Configure WAKEUP, KEY1 pins as the input function */
- GPIO_IN_Configuration();
- /* Configure LED1, LED2 pins as output function */
- GPIO_OUT_Configuration();
- /* Infinite loop to read data from input pin and then output to LED */
- while (1)
- {
- //GPIO_MainRoutine();
- uint32_t count = 5000000;
- static uint32_t TmpStatus = 0;
- while (count--) __NOP();
- GPIO_WriteOutBits(HTCFG_LED1, HTCFG_OUTPUT_LED1_GPIO_PIN, TmpStatus);
- TmpStatus ^= 1;
- GPIO_WriteOutBits(HTCFG_LED2, HTCFG_OUTPUT_LED2_GPIO_PIN, TmpStatus);
- }
- }
