Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.

I'd like to use the espruino for data logging purposes and transmit the log data to a host by WiFi. The file system should be used to buffer data in between connections, but the file system API is only able to work on files as a whole at the moment. So an indexed block read/write improvement would really help, and/or even better a file object (or handle) that was able to keep the file open.
I haven't yet looked into the Espruino source code, but I'd like to help on building the API. What environment/toolchain are you using for building Espruino (I'm sure I've read that somewhere earlier on, but I've forgot where it is).
