  Hi folks

  Just had a set of SG90 servos delivered and having trouble with the servo module.

  The example here: http://www.espruino.com/Servo+Motors#lin­e=13,25,26 shows it moving from 0 to 1, which is actually only 90 degrees, not 180 as these servos support.

  If you use:

  analogWrite(pin, 0.04, {freq:50});
  

  It goes to -90 ... and

  analogWrite(pin, 0.15, {freq:50});
  

  It goes to +90, demonstrating the full 180 degrees of motion... but the servo module doesn't seem to support it. They require either 1 (-90), 1.5 (0 or middle) or 2ms (+90) pulses at 50Hz

  Any help would be appreciated.

  Hi folks

  Try as I might, I cannot get Espruino to compile without flooding the screen with errors.

  Steps thus far...

  1) Installed Ubuntu 16.04
  2) sudo apt-get install gcc-arm-none-eabi
  3) sudo apt-get install git
  4) git clone https://github.com/espruino/Espruino.git­
  5) make clean && DFU_UPDATE_BUILD=1 BOARD=PUCKJS RELEASE=1 make

  See attached for errors.

  Any thoughts would be much appreciated.
