• Heatshrink question

  I see that you've added heatshrink compression to Espruino and that the Flash module is setup to use it, but I'm not sure if that is active at the moment as I don't see the macro USE_HEATSHRINK being set anywhere.

  Is it possible, and would it make sense, to have heatshrink jswrap-ed so that we could use it when playing with strings and typed arrays in javaScript?

  Is it worth considering hardware flow control on the usart with the ESP8266?

• How to go about tracking down this error?

  Funny you should mention using SPI flash, I'm in the process of investigating that as an option to buffer the incoming multipart/form-data and then parse that, saving the file parts to an SD card.

  I've tried software SPI and the result is much the same. Its slower in in the first instance for each write, not as bad as half the speed of the best hardware SPI rate I can get. However it suffers delays of the same length (~0.2 sec) as in the log above with similar frequency and these delays do block the serial interrupts the same way as for hardware SPI.
