stm32修改堆栈大小（堆栈空间不敷导致死机）
1. 选择调试下载方式
用STM32CubeMX工具选择好芯片后，在Trace and Debug里面选择下载调试方式。
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvMWIzNDAzMWNiMzc1MjUzNDE2MDg3NDYwZmIzNWNkMmEucG5n
2. 选择晶振和时基
在System Core里面设置晶振和时基
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvMTcwZjE2MWFmZjZiMzk1Y2UxNjBhNjFjY2QzMmVhY2YucG5n
3.打开CRC检验
在Computing中打开CRC,勾选Activated即可。ST使用TouchGFX必须使能CRC。
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvZTc5Y2M1M2IwNDVhZDJjOWU5NTZkMDYzMzM5ZWY5M2UucG5n
4.使能DMA2D
在Multimedia中打开DMA2D,勾选Activated，并设置和使能DMA2D中断。
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvYzBkMDhmZjEyMmY0MDkzMjZkNmYzMjEwNDdjMzVmMzIucG5n
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvNWU2ZTE1ZDYxMzQyNzA1ZjdlODRlMzBhNmMzMThkNjUucG5n
5.设置SDRAM
Connectivity中找到FCM,相关设置如图：
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvOThjMzU2N2JlOTc3MjU1N2YzMjg3YWQ5ODBlM2E0YjQucG5n
下面的相关设置参考《野火29-电容触摸屏-触摸画板》的bsp_sdram.c文件中的 SDRAM_Init(void)函数内容举行设置。也可根据数据手册设置。额~~~我还不会看数据手册。
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvNGEzY2Q4OTNhYWMzMjllZGVjMzYwZjI1MTNiMmM0NjUucG5n
切记：必要对 SDRAM的片选信号和时钟使能信号举行重新设置，否则屏幕只能点亮，而不能正常显示touchgfx。 PH6引脚更改为FMC_SDNE1，PH7引脚更改为FMC_SDCKE1。
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvMDFlNzk4NTcwMDNjMTYwNTAwY2IyYjhjNGZiMTEyZjUucG5n
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvYmI0ZWZjNTQzOWFkNGRkZmEyM2I5OGVmMWQ5ODYwNTkucG5n
7.设置LTDC
在Multimedia中选择LTDC，并使能LTDC中断。
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvYTkxYjZmMTg2MzM5OWY0YjRiNmZjMzY5MjYxYWE3ZjQucG5n
下面的相关设置参考《野火29-电容触摸屏-触摸画板》的bsp_lcd.c文件中的 LCD_PARAM_TypeDef lcd_param数组内容举行设置。
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvY2Q5OWIzMTIwY2U0MTE2ZWFiNzU2NDRlNWI5ZGEwMmUucG5n
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvODA1MTAzMDg5NWFlNWUzYWNjMGEwNjkxNGU5ZGRmZjkucG5n
必要对LTDC的相关引脚重新手动设置，和原理图一一对应，这里使用RGB565,相关设置引脚如下
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvMjM2YTM0ZmE2NDhlMmI5MTQzMWEwMjQ5MGZiYTE1YzUucG5n
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvNzdmZTA1YTAwZGFiYWY0ODJlNDcxYzUzODk5YWZhYjcucG5n这里可参考手把手教你制作TouchGFX的工程模板 里面先容了触摸中断的引脚设置方式。本文未用到此方法，因为触摸中断已经在野火stm32h743xih6 touchgfx 添加触摸代码(二)的bsp_i2c_touch.h文件中定义。
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvYjA2NDJlMDA3ZTFlMzUwNDNiZGEyOGRjNWUwOWJjZDEucG5n

8.检查相关中断是否开启
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvNWRiYTYzMzU3MGIxYjU3ZWM2MTljZjJhZDAzNzI5MDIucG5n
9.设置FREERTOS
在Middleware中选择CMSIS_V1
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvMDU1Mjk4MDg4ZWQwODliMTFhMDc0MmRiYmU0YzhkYzcucG5nhttps://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvZTZhNjJlOTZkM2JiOWIyNGRiNTRjMjg0OGM0NmE1MTIucG5n

10设置touchgfx
在Software packs中设置 touchgfx
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvMDhiN2RkYjA3ZmVhNzcwZTE5NjNiZDcwNjg2ZTc3Y2UucG5n
11.设置时钟
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvNzI2MTA3YWY3NzY2Yjk1ODQxYzFjMTZlZmI0MjViMzYucG5n
野火七寸屏最大时钟33Mhz,FMC最大支持240Mhz
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvZmFhNDA2YmE0NjYxNjgzOWEwNTMzZTZjMGZmZTRlNzYucG5n

12.天生工程
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvNTQwMzE4Zjk2N2M2YWU0OGIwYjM1MjZiYmViZGIxOWEucG5n
13.先使用touchgfx designer工具设置GUI
步骤12完成后直接打开mdk工程会报错
在STM32cubemx天生的文件夹下的TouchGFX中打开ApplicationTemplate.touchgfx.part设置GUI界面。
https://dis.qidao123.com/imgproxy/aHR0cHM6Ly9pLWJsb2cuY3NkbmltZy5jbi9ibG9nX21pZ3JhdGUvNGNmYTdhYWVlM2ZhMzhjZGM5NWZjNTI2ZTg2OTU3NDQucG5n
14.添加SDRAM相关代码
在main.c中添加SDRAM的相关代码
