Hello

I want to use mibadc ,for only one Io for adc.

I hope to trigger many times, and read the data later.means read more data.

I find mibadc is many data for more io, I want only one io for more data

How to achieve

Hi Whong,

There are totally 64 buffers for 3 ADC conversion groups. You can use threshold interrupt, and read the ADC conversion data from the ADC RAM in the INT ISR.

Since this device doesn't have DMA, it will take time for CPU to read those conversion data. I will write a example project for this. How about to try another device which supports DMA?
