Greetings,

I'm developing a system to test ECG equipment using the STM32F446RE board and I need to upload a file to the flash containing samples of a ECG signal, I'm currently using mbed to test the ADCs and DACs, but I don't know which software I could use to upload the file, I'm also not familiar with the existing libraries and the necessary commands to read a file from the flash memory. Does anyone knows how to solve this problem?

Best regards,

Daniel Almeida

Hello.

You can convert your binary samples to C arrays and use inside your program as constant

Search  from your browser to find  a converter 'bin to c'

Hi, 

this solution seems simple and easy to implement the problem seems to be the amount of code.

Depends on your mode of connectivity. If serial you can manage data in/out of flash using X-MODEM, etc supported by your average terminal application.

You could perhaps pretend to be a USB MSC, and download files directly, or use a Micro SD card to hold data sets.

I'm comunicating with the board using the USB port (serial port), but I don't know the commands needed to insert data in the flash memory.

The others solutions you've mencioned I'm not familiar with them.
