尝试移植标准库的fsmc驱动lcd到hal库上（未完成）
作者：互联网
手头有一个红牛的stmf103开发版。以前用arduino 用它点灯跟使用串口。用起来很简答。上边的触摸屏是 ili9325.使用的是fsmc驱动 。16位接口。可以看到主频72M的开发版刷新屏幕非常的快。红牛开发版的例程都是基于标准库3.5的。
8.92 rEU:/ 红牛开发版自带的屏幕测试 https://v.douyin.com/jtbawFR/ 复制此链接，打开Dou音搜索，直接观看视频！
尝试把这个屏幕驱动移植到arduino上，这样就可以用arduino的api来捣鼓这个板子了。pio下载stm32库，还要下载arm的gcc编译器等。可能要等很久pio才能准备好。然后发现stm32的arduino库是基于hal库的一层包装。不能直接拿来用。
网上基本没有用fscm跑arduino的 。我只找到了这一个 零知实验室--技术资料 (lingzhilab.com) 它的豪华版开发版是STM32F407VET6 。可以下载到他的代码。找出它的fsmc相关代码

但是它的代码是基于f4的hal库，针脚也用的不一样。还是得改。只能从这获得思路
不得已搬出了STM32CubeMX 看看它会怎么自动生成代码 照猫画虎配置一同。然后观察它自动生成的代码

用这个魔改红牛的标准库程序，把标准库里跟fsmc有关的都换成hal调用

发现一个问题 无论怎么修改头文件的引用，HAL_SRAM_Init在pio里始终没有被编译。搞得我无比头大。最后我看了下cube生成的代码 里边除了gpio跟fsmc其他外设都关了。但是看pio里的hal库 默认所有功能都开着。再仔细看。源码里有个if define fsmc才会编译的句子 尝试在pio的配置文件platformio.ini里加上-d
[env:genericSTM32F103ZE] platform = ststm32 board = genericSTM32F103ZE framework = arduino build_flags = -D USBD_USE_CDC -D PIO_FRAMEWORK_ARDUINO_ENABLE_CDC -D PIO_FRAMEWORK_ARDUINO_USB_FULLMODE -D USBCON -D HAL_SRAM_MODULE_ENABLED 这样终于不报错了。 但是读取的显示屏id始终不对是0000.目前没有找到办法。
