Continuous ADC application with completion interrupt [ADC of STM32] June 16, 2020 Last updated : March 30, 2022 Mechanotoro This program is an introduction to the combination of AD conversion and interrupts ; interrupts are supposed to be generated each time AD conversion is completed, and as it is, the frequency of interrupts is too high to be. It's better in SAMC and SAML where the scan is controlled with a bit mask. The amount of data to be transferred (up to 65535) is programmable. [Parameter Settings] Continuous Conversion Mode: Enable. The STM32 HAL makes it a little easier to use, as there's some built-in functions that control the DMA with the ADC, specifically. DMA channel 12 would generate interrupt triggered by COCO (conversion complete) signal form ADC1 and at that interrupt ADC result would be copied to another separate buffer(ADC count would be used for transient detetcion). We will be comparing the arduino ADC with STM32's ADC.
