I am working on a project in which -
How to reconstruct input signal by using DAC?
- I have to continuously monitor the the ADC input on a microcontroller and check if the value crosses a certain threshold.
- If the value crosses the threshold, start a timer for 100ms.
- Within this period,use DMA to tranfer ADC samples to a buffer.After the period elapses,a periodelapsed callback will be called where I stop the timer and the ADC DMA transfer process.
