Software

The software of the Microncontroller is under the branch COM_SW_Test_Development.

It is using the version 1.0 of the library from waspmoteapi. It is on github on this past commit. The original source code is modified in order to be used on the LPC microncontroller. The library is on the version 3.

From the original library, version 1.3 of waspmote it have been modified:

  • Original print was with USB

Update 20 Feb

I put the cables to the LPC-Link 2 in order to program the microcontroller.

  • PURPLE - RESET
  • RED - 3.3V

And also I connected the board to the PCB Breakout board:

  • IMPORTANT The voltage is 3.3V
