im writing some data to sd card, by writing new line of data for each change. It all works fine, but because this setup will be installed into some bigger prototype device systems samples that will be away from me for couple of months, there will be a loooot of data stored there. One of the data is a count of some cycles and i type down the each new value in new line, for example:
NUMBER OF CYCLES 2 3 4 5 6 7 ...
Is it possible to just setup matrix or some function that would always write on same spot in sd card, so that it would look like this(each new cycle count would be typed on same spot): NUMBER OF CYCLES = 7
Thanks in advance fro any help :D
