我想要一个代码，通过具有以下设置的stm32f732控制器读取adc ad7699： IN[7：0] 单极性参考 GND，按顺序排序 单极点滤波器的全带宽 内部基准电压源/温度传感器禁用，缓冲器启用 启用序列器 无CFG寄存器回读

以下是使用STM32 HAL库的示例代码。在这个代码中，我们使用DMA和ADC的连续模式来读取AD7699，具体设置如下：

- 使用ADC1和DMA2
- ADC1的采样时间为3个ADC时钟周期
- 使用单极性参考GND
- 按顺序排序
- 使用单极点滤波器的全带宽
- 禁用内部基准电压源和温度传感器，启用缓冲器
- 启用序列器
- 禁用CFG寄存器回读

请注意，这里的代码仅给出了ADC的初始化和DMA设置，你需要根据你的具体应用程序进行修改。
