前言
用STM32F407作的产品板子，遇到领导奔放的想法，内存有点不够用。
一般的工程，瓶颈都在内存上。而不会说存代码的FLASH区不够了。编译完的bin文件300KB, 那代码量都不少呢。
ST代理商的FAE推荐用STM32H743, FLASH 2MB, RAM 1024KB.
今年的年假请的NB, 请到2月20日去了, 可以作预研。
上个F407的板子，是以前同事好久前写的，用的是固件库。
预研一下STM32H743, 只是为了用更大的片内内存. 但是ST官方，现在已经只提供HAL库了。
h743的固件包现在为 stm32cube_fw_h7_v160.zip
整了一块ST官方的板子STM32H743I-EVAL2. 看看官方demo是怎么写的。
官方板子做的很漂亮，秀一下板子:P
\STM32Cube_FW_H7_V1.6.0\Projects\STM32H743I-EVAL\Examples 是知识点的demo, 每个demo只验证一个知识点。
反正都要过一遍，随便挑了一个知识点 GPIO_EXTI开始第一个知识点的预研。
GPIO_EXTI 讲的是H743如何响应外部GPIO中断。e.g. 按下一个键，如何通过外部中断的方式，对按键引起的外部中断做出响应。
试验
先过一遍官方的GPIO_EXTI工程，然后用STM32CubeMX重建一个工程。
STM32CubeMX当前版本是5.5.0， 先从开发板选择器，先选择STM32H743I-EVAL2，保存一个.ioc备用。
STM32H743XIHx
Package = TFBGA240
Flash = 2048KB
RAM = 1024KB
FREQ = 480MHZ
从MCU选择器开始工程的配置, MCU选择为 STM32H743XI
PC.13是个按钮，选择为外部中断方式。
开启NVIC中的外部中断。
将RCC使能，HSE,LSE都用外部晶振。
从en.MB1246-b0x_schematic.pdf 可知, HSE晶振为25MHZ, LSE晶振为32.768KHZ.
参考官方板子的.ioc，调整时钟参数。
但是要使用HSE外部晶振25MHZ，让CPU时钟频率配置在最大的480MHZ.
填好25MHZ的HSE, 选PLL锁相环为时钟源，选CSS Enable, 在D1CPRE Clock中填入480, 然后回车，让CubeMX来自动调整时钟到最大的可能方案。
设置一下产生代码的选项。
这一步，不要选“将不用的引脚设置成模拟输入”，要不初始化GPIO的代码很长，看不清了。
正式工程可以选。
现在可以生成初始化代码了。
生成的工程代码很干净，每一种外设都为单独的.c实现。
工程选项中要确认CPU时钟频率和优化等级。
可以看到选项中的CPU时钟和用STM32CubeMx配置出的HPRE时钟频率是一样的。
优化等级要整成0，要不断点断不下来。
现在单步一下SystemClock_Config()，看看是否使用了外部晶振HSE.
进入SystemClock_Config(), 可以看到PLL的参数和CubeMX配置的相同。
可以看出，是使用了外部晶振。
RCC_OscInitStruct.PLL.PLLM = 5;
RCC_OscInitStruct.PLL.PLLN = 192;
RCC_OscInitStruct.PLL.PLLP = 2;
RCC_OscInitStruct.PLL.PLLQ = 2;
RCC_OscInitStruct.PLL.PLLR = 2;
关于时钟tick是否为1ms, 后续看官方demo. 看到用了(HAL_TICK_FREQ_DEFAULT = HAL_TICK_FREQ_1KHZ), 好像tick是1ms.
现在可以添加外部中断响应的代码了
因为可能要重复使用CubeMx来调整硬件设置，来重复生成新的初始化代码。
所以，要将自己的代码放在ST约定的代码边界里面。可以防止重新生成初始化代码时，冲掉自己手写的代码。
/* USER CODE BEGIN x */
// my code need write on here
/* USER CODE END x */
先看看如果外部中断响应了，要干点啥。
官方demo中，是翻转LED灯，我们也这样搞。
从\resource\en.MB1246-b0x_schematic.pdf中可以看出PF.10是一个LED灯。
先增加灯的初始化和翻转代码。
/* USER CODE BEGIN 2 */
void LED_init(void)
{
GPIO_InitTypeDef gpio_init_structure;
// PF.10 is a LED
__HAL_RCC_GPIOF_CLK_ENABLE(); // enable pin clock first
gpio_init_structure.Mode = GPIO_MODE_OUTPUT_PP;
gpio_init_structure.Pull = GPIO_PULLUP;
gpio_init_structure.Speed = GPIO_SPEED_FREQ_HIGH;
gpio_init_structure.Pin = GPIO_PIN_10;
HAL_GPIO_Init(GPIOF, &gpio_init_structure);
// set pin default status
HAL_GPIO_WritePin(GPIOF, GPIO_PIN_10, GPIO_PIN_SET);
}
/* USER CODE END 2 */
EXTI15_10_IRQHandler()中调用HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_13);
HAL_GPIO_EXTI_IRQHandler（）调用HAL_GPIO_EXTI_Callback（）
HAL_GPIO_EXTI_Callback（）是个弱函数，我们要自己实现。
void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin)
{
/* Prevent unused argument(s) compilation warning */
// UNUSED(GPIO_Pin);
// PC.13 is the button, as the exti
if (GPIO_Pin == GPIO_PIN_13) {
HAL_GPIO_TogglePin(GPIOF, GPIO_PIN_10); // PF.10 is a LED
}
}
这时，响应外部中断的代码就完成了，测试好使。
每按下PC.13按键，PF.10的LED灯就翻转。
备注：调试时，如果在官方demo和自己工程之间来回切换调试，需要重新插拔官方板子上的STLINK3的USB口才能重新调试当前工程。

参考和迁移官方demo的知识点展示，可以让新手很快上手，将新的MCU编程应用到实际工作当中。
大大降低了时间成本。
