Detailed Description

STM32 ADC 循环采样的 GPDMA 适配器 / GPDMA adapter for circular STM32 ADC sampling.

持有一个线性循环节点，采样缓冲区由调用者提供；启动时替换 BSP 链表，停止后恢复。 Owns one linear circular node while borrowing sample storage; replaces the BSP list on startup and restores it after stopping.

Note

由所属 STM32ADC 在构造时启动、析构时停止，期间独占对应 ADC/DMA 句柄。 Started by the owning STM32ADC constructor and stopped by its destructor, with exclusive ADC/DMA handle ownership throughout that lifetime.

Member Function Documentation

Start()

HAL_StatusTypeDef LibXR::STM32GpdmaAdcAdapter::Start	(	ADC_HandleTypeDef *	adc_handle,
		uint32_t *	buffer,
		uint32_t	sample_count,
		size_t	buffer_size )

挂接循环链表并启动 ADC DMA / Attach the circular list and start ADC DMA.

Parameters

adc_handle	已关联静止循环链表的 ADC 句柄 / ADC handle with a stopped circular list.
buffer	DMA 可访问的半字采样缓冲区 / DMA-accessible halfword sample storage.
sample_count	每轮采样数，单位为半字 / Samples per cycle, in halfwords.
buffer_size	缓冲区字节数 / Available buffer size in bytes.

Returns

HAL 启动结果 / HAL startup result.

Stop()

HAL_StatusTypeDef LibXR::STM32GpdmaAdcAdapter::Stop

(

ADC_HandleTypeDef *

adc_handle

)

停止 ADC DMA 并恢复 BSP 链表 / Stop ADC DMA and restore the BSP list.

Parameters

adc_handle

启动时使用的 ADC 句柄 / ADC handle used at startup.

Returns

HAL 停止结果；失败时保留私有链表 / HAL stop result; retain the private list on failure.
