PUGAUGE - Low Power Display Processor
The PUGAUGE is intended to be a base platform for devices to display Information in an environment where low power requirements are mandatory.
Examples are:
- Bike computers
- Thermometers
- mobile measurement devices
Hardware
Overview
- 8-Character Segmented LCD 14-segment Display
- Atmel AVR ATmega6490A AVR microcontroller
- Atmel ISP Connection
- Arduino Upload Serial Interface
- A Status LED on MCU port PB0
Software
Platform
The PUGAUGE is intended to be Arduino-compatible. The application software shall benefit from the ease of use, familiarity of many developers and availability of many libraries for sensors and other peripherals.
Therefore, an extension to the Arduino IDE is developed to allow the PUGAUGE being selected as a board type in the Arduino IDE. This should not be too complicated, as the PUGAUGE processor is an Atmel AVR processor closely related to the Atmel AVR processors used in the Arduino UNO and MEGA.
Additionally the atmegaboot bootloader for the Arduino is being modified to run on the PUGAUGE and allow Arduino sketches to be uploaded onto the PUGAUGE.
For the time being, a board/platform package is available with working minimal build and upload configuration:
