hsadc_dual_parallel_conversion
Overview
The hsadc_dual_parallel_conversion example shows how to use the both converter parallel at the same time with HSADC driver.
In this example, the HSADC is configured as “kHSADC_DualConverterWorkAsTriggeredParallel” (default) work mode. User should indicate 4 channel pairs to provide the differential voltage signal or 4 channels to provide the single ended voltage signal as the inputs for HSADC sample slots. If user select channel 6 and 7 of converter A or converter B to sample for specific sample slot, the sub mux channel number of channel 6 and channel 7 also should be configured. The sample slots would be assembled into the two conversion sequence for each converter.
In “kHSADC_DualConverterWorkAsTriggeredParallel” mode, the converter A converts sample 0 and sample 1 (sample 0-7 are available) and the converter B converts sample 8 and sample 9 (sample 8-15 are available). As the “simultaneous mode” is enabled by default, the converter A’s control logic can operate both the two converters to start and stop together.
When running the project, typing any key into debug console would trigger the conversion. And then, the conversion result data of the four sample slots (Sample 0, 1, 8, 9) would be displayed in the terminal.
Running the demo
When the example runs successfully, following information can be seen on the OpenSDA terminal: Press any key to trigger the conversion … Sample 0 Sample 1 Sample 8 Sample 9 Result 0 Result 1 Result 2 Result 3
