Expand description

Successive approximation register (SAR) analog-to-digital converter

Modules

ch
Register block Unspecified
enable
Enable or disable SAADC
events_calibratedone
Calibration is complete
events_ch
Register block Unspecified
events_done
A conversion task has been completed. Depending on the configuration, multiple conversions might be needed for a result to be transferred to RAM.
events_end
The SAADC has filled up the result buffer
events_resultdone
Result ready for transfer to RAM
events_started
The SAADC has started
events_stopped
The SAADC has stopped
inten
Enable or disable interrupt
intenclr
Disable interrupt
intenset
Enable interrupt
oversample
Oversampling configuration. The RESOLUTION is applied before averaging, thus for high OVERSAMPLE a higher RESOLUTION should be used.
resolution
Resolution configuration
result
Register block RESULT EasyDMA channel
samplerate
Controls normal or continuous sample rate
status
Status
tasks_calibrateoffset
Starts offset auto-calibration
tasks_sample
Takes one SAADC sample
tasks_start
Starts the SAADC and prepares the result buffer in RAM
tasks_stop
Stops the SAADC and terminates all on-going conversions
