Enable the latest-frame ADC stream policy.
|
|
|
|
This mode is intended for slow-changing or status-like ADC values, such
|
|
as battery voltage, temperature, potentiometer input, resistor-divider
|
|
voltage, or board health monitoring.
|
|
|
|
The DMA buffer stores exactly one complete ADC scan frame. Old values
|
|
may be overwritten. This mode does not require DMA half-transfer or
|
|
transfer-complete data interrupts, and it does not allocate a framework
|
|
FIFO.
|
|
|
|
This option may be enabled together with RT_ADC_STREAM_USING_FIFO. The
|
|
active policy is selected per stream at runtime.

Enable the FIFO ADC stream policy.
|
|
|
|
This mode is intended for continuous and loss-sensitive sampling. The
|
|
DMA buffer is used as a staging buffer, and completed DMA data events
|
|
are copied into a ringbuffer for ordered blocking reads.
|
|
|
|
FIFO mode requires DMA data events. The default DMA event mode uses both
|
|
half-transfer and transfer-complete events to reduce read latency. A
|
|
stream configuration may select full-only events to reduce interrupt
|
|
frequency, at the cost of higher latency and larger data bursts.
|
|
|
|
This option may be enabled together with RT_ADC_STREAM_USING_LATEST. The
|
|
active policy is selected per stream at runtime.

Enable the ADC V2 MSH command.

This option exports the "adc" shell command for probing ADC devices,

configuring channels, reading raw samples, reading voltage values, and

reading one ADC sequence. When RT_ADC_USING_STREAM is enabled, stream
|

subcommands are also available.

the ADC V2 framework and driver APIs available.
