The NSL Sceptre

Is basically a slight remix and cheaper version of the Elektor sceptre, it's functionally the same but we're bringing the costs down.

Install WinARM

WinARM it uses the ELF version, so the 2006 one

Programmers Notepad is also useful if you're IDE-less

programmers notepad

Grab the 'Software' link from here elektor

unzip and install it, install WinARM, add the utils\\bin and \\bin folder to your system path, open programmers notepad, open the Makefile and select Make All

Technical specifications:

  • 32-bit ARM7TDMI-S LPC2148 microcontroller, 512 KB flash, 40 KB RAM
  • USB 2.0
  • Bluetooth (Class 1 or 2)
  • SD card reader
  • Serial port via USB (e.g. for in situ programming)
  • 3-axis accelerometer
  • DS18B20 thermometer
  • Real-time clock
  • All microcontroller pins accessible
  • Battery or USB port powering
  • Li-ion battery charger
  • Compact: 6 × 8 cm
  • Open-source tools, software, and hardware
  • Open-source extended library

Normally it goes for $144 + bluetooth module.

Status

PCB has been redesigned, submitted to BatchPCB (arrived) Built

First two have been built and tested, accelerometer works on hardware, not software side.
