swap-file / automaton Goto Github PK

Hi,

Many thanks for making this repo publicly available! I got here from the seeedstudio forum and could reuse many things of what you already developed :).
At the moment I have two questions I wanted to ask you. The first is around how BLE works with the bluefruit library. In Automaton_Hand, you have the ble_send function that writes the payload into the hand_characteristic. Then, in Automaton_Head, you set up the lsbLEFT and lsbRight characteristic, both with a setWriteCallback. To me, this sounds like whenever a hand writes something, the head goes into the callback without explicitly calling a "valueWritten" routine or something similar. Is that correct? I couldn't get this to work yet if that is what this is doing. Also, what then is the difference between this and the notify property of lsbVIBE? I thought that this will work without calling a special routine to update the value. In any case, I'll have to read up a bit on the bluefruit library, but I hoped you could give me some insight here.

The other thing I was wondering was the filesystem you seem to have implemented. I had the idea of writing some files to the 2MB onboard flash so they would be permanently stored there, and then retrieving them in some runtime code. Is this what you are doing here? I see that you open the file /automaton.txt; do you get this from the flash memory? Somewhere I read that the filesystem required the mbed core, which I really want to avoid, so I was delighted to see that you got some filesystem working, if I understand your code correctly?

cheers,
simon
