WebFeb 13, 2024 · SDK no-os. I am using the ad9361 SOM and I can capture waveform correctly using: #define ADC_DMA_IRQ_EXAMPLE. This works only once. I mean I want to keep capturing without calling adc_capture inside a while loop. PL has an FM demodulator and generates 320 bytes every 40 ms. If I run adc_capture (16384, … WebIn your case the ADC keeps converting after the DMA has finished, and the DMA ISR can't halt the ADC quickly enough to prevent another conversion happening. Since the DMA has already been disabled this extra trigger is missed, and the trigger state is left high. This issue doesn't just affect multiple sample conversion.
