Data Acquisition of STM32F7 ADC DMA

[AE104]

Hello,

On my custom-designed PCB, I use STM32F767 ADC for acquisitIon analog signal input in DMA mode. My method is collecting data that running the code in Keil IDE debug mode and then export the converted digital values in a .txt file with a .ini function. For evaluating data, I copy the data into excel file. The problem is that I can export only one buffer size but I need to export more than a hundred buffers. So it takes time to run the code, export the values with. ini file, and then copy the values in an excel file. Hence, does anyone suggest to stream data for more than one hundred times?

Thank you,

One common method is to stream the data over UART and capture/log it in a terminal software. The STLINK-V3MINI and similar debug adapters (including STLINK/V2-1) have pins dedicated to a UART<->USB interface which can be used for this purpose.

Depending on specific needs, SWO can also be a reasonable option.

And another pretty advanced technology is SEGGER RTT:
