单片机解密stm32f407单片机通过并口驱动
单片机解密单片机源程序如下:

- //AD_OS1 PG3
- #define OS1_1() GPIOG->BSRRL = GPIO_Pin_3
- #define OS1_0() GPIOG->BSRRH = GPIO_Pin_3
- //AD_OS2 PG2
- #define OS2_1() GPIOG->BSRRL = GPIO_Pin_2
- #define OS2_0() GPIOG->BSRRH = GPIO_Pin_2

- //AD_RESET PB14
- #define RESET_1() GPIOB->BSRRL = GPIO_Pin_14
- #define RESET_0() GPIOB->BSRRH = GPIO_Pin_14
- //AD7606 FSMC总线地址，只能读，无需写
