GPIO，英⽂全称为General-Purpose IO ports，也就是通⽤IO⼝。嵌⼊式系统中常常有数量众多，但是结构却⽐较简单的外部设备/电路，对这些设备/电路有的需要CPU为之提供控制⼿段，有的则需要被CPU⽤作输⼊信号。⽽且，许多这样的设备/电路只要求⼀位，即只要有开/关两种状态就够了，⽐如灯亮与...

assert_param(IS_GPIO_PIN(GPIO_InitStruct->GPIO_Pin)); 1. 2. 3. 4. 5. 6. 首先是一些参数定义,和assert_param函数,这个函数的意思是检查参数是否有效,如 assert_param(IS_GPIO_ALL_PERIPH(GPIOx));就是检查GPIOx这个参数是否有效,假如我输入一个GPIOK进去,那就是无效参数,会报错。
–using a strapping pin for my SPI display. Pay special attention to all pins mentioned in section 2.3 “Strapping Pins”. They all are trouble. So other than IO0 (for boot mode) I did not connect any of them –missing pullups on #EN and IO0 and missing capacitor on #EN. The data...
