Pulse Density Modulation (PDM) microphone driver
Structs§
- Config
- PDM microphone driver Config
- Interrupt
Handler - Interrupt handler
- Pdm
- PDM microphone interface
Enums§
- Edge
- PDM edge polarity
- Error
- PDM error
- Frequency
- PDM_CLK frequency configuration. Enumerations are deprecated, use PDMCLKCTRL equation to find the register value. The 12 least significant bits of the register are ignored and shall be set to zero.
- Operation
Mode - PDM operation mode
- Ratio
- Selects the ratio between PDM_CLK and output sample rate
- Sampler
State - The state of a continuously running sampler. While it reflects the progress of a sampler, it also signals what should be done next. For example, if the sampler has stopped then the PDM implementation can then tear down its infrastructure
Traits§
- Instance
- PDM peripheral instance
