adc_watchdog
Overview
The SAR ADC watchdog example shows the simplest way to use the SAR ADC driver.
In this example, the user-specified channel is used to execute in the normal conversion scan mode. The end-of-conversion, pre-sample, and DMA transfer features of each channel in the conversion chain are disabled. The analog watchdog function is enabled to monitor the conversion result, and the low and high threshold interrupt is enabled, The user should provide a voltage signal to each conversion channel. Running the project, after the channel conversion is completed, the conversion data will be compared with the low and high threshold values. If the conversion data is lower than the low threshold value, the low threshold interrupt will be asserted, if the conversion data is higher than the high threshold value, the high threshold interrupt will be asserted, and if the conversion data is valid, the conversion data will be printed on the debug console.
