Hey everyone!
I am having some problems to writing data to a microSD card through 4-wire SPI link. Checked the interrupt pin with scope and the issue is due to the fprintf line of the code.
Unfortunately I can't run the SPI clock too high, because a sensor has to be connected with an around 1m long cable to the mbed board.
So my question would be is it possible to run the two SPI links on a different speed? Not sure keep changing it in the code is a good solution?!
Possible to use sd mode to write to the sd card?
Thanks in advance!
