以下是基于STM32 HAL库的ADC128S102应用代码示例:

```
在此示例中,使用了 SPI1 控制 ADC128S102 的数据传输,使用 GPIO 控制片选信号。每次循环中发送 8 个字节的数据到 ADC128S102,然后读取每个通道的 ADC 值,最后通过 HAL_Delay() 函数等待 10ms 后再进行下一次循环。
需要注意的是,该示例仅提供了 SPI 和 GPIO 的初始化代码,具体的 ADC128S102 配置需要根据实际情况进行设置。例如,可以通过修改 tx_data 数组的数值来控制 ADC128S102 的配置,详细说明可以参考 ADC128S102 的数据手册。
