Hello everyone. I’m trying to connect a SD Module (SPI interface) with Zerynth because I need to make a kind of datalogger.
I saw the the Filesystem example, but some things are not clear to me.
ww = os.open(‘0:zerynth.txt’, ‘w+’).
- What is “w+”?
- When I need to append data in the end of file, I just need to call ww.write()?
- I need to call ww.close()? My device starts to save data when is powered on and only stops when is powered off. In order not to lose data, ww.write() is sufficiente?
