Hello guys,

Is it possible to write data on SD card through interrupt?

(maybe it can help me to increase the speed while writing data into sd card)

Depending on how fast the main program should be executing, it may not be a good practice. However, unlike the serial port, SPI transactions aren't affected by disabled interrupts; so it should be possible.

but I think the speed of writing data is higher than main code and it is not possible. Do you think is it posssible to oped the file on sd card, write data for one hour and then close it? Or the file must be closed each time with new data?
