Hello everyone, my first post (and first project).
I would like to change JustFATLogging so it can log more than just the
accelerometers. I would like to keep the new app flexible, so the next person
around will be able to decide if she/he wants to add Gyro reading, and/or other
sensors. This requires that some constants (record length, etc.) will become
constants, preferable in the .h file. I would like it continue and to not use
the radio because the uSD card has lower energy needs. As I was reading the
code I ran into some constants which I do not understand.
Here are my questions:
1) I am trying to add to JustFATLogging. Is there a better app to start from,
or code fragments that I can use from other app and plug it into the right
places in JustFATLoggging?
2) The sbuf variables have a size of 512 and they are of type uint16, but the
call to fwrite writes only 1020 Bytes. Why not 512*2B=1024 Bytes?
3) I assume that DMA0.transferDone function is triggered when a DMA transfer is
complete, correct?
In that function, what is the constant of 170 used for?
PS: As I was reading JustFATLogging I added a lot more comments. If anyone is
interested I can post the code.
Thanks,
Rahav
