硬汉大哥，现在做项目用H750驱动AD7606（并口8080时序的），用的你们的驱动调试，
出现的问题是：串口读数一开始8个通道为-1，在采集口接入3.3V电压后8个通道读数为2669
FMC的接线如下：
接线配置：
PE6/BUSY
PC6/CONVST
PC8/OS0
PC9/OS1
PC10/OS2
PC11/RANGE
PC12/RESET
PD0/FMC_D2
PD1/FMC_D3
PD4/FMC_NOE
PD7/FMC_NE1
PD8/FMC_D13
PD9/FMC_D14
PD10/FMC_D15
PD14/FMC_D0
PD15/FMC_D1
PE7/FMC_D4
PE8/FMC_D5
PE9/FMC_D6
PE10/FMC_D7
PE11/FMC_D8
PE12/FMC_D9
PE13/FMC_D10
PE14/FMC_D11
PE15/FMC_D12
以下是驱动AD7606的代码 我是以定时采集的 所以没初始化BUSY引脚
就是在定时中断函数中
定时启动，然后读取

不是我不写注释，注释都是乱码啊
