Alti Duo Files (using an ATmega328)

Dual Alti Atmega 328-03-04-2013-eng.pdf This is the altimeter documentation. Download it if you want to see all the diagrams and fonctionalities of the altimeter and how it is all working
Dual Alti kit build instructions.pdf The kit building instructions. If you want to build a kit here you. will find some detailed instructions to build one
Dual Alti kit Operating instructions-03-04-2013-eng.pdf Just some instructions to help you installing and using the kit
AltiDuoV1_0.zip This is the stable code for the Alti Duo (ie: I have successfully fligh rocket with that code.
AltiDuoV1_1.zip This is the stable code for the Alti Duo (ie: I have successfully fligh rocket with that code.
AltiDuoV1_2.zip This is the stable code for the Alti Duo (ie: I have successfully fligh rocket with that code.
AltiDuoV1_3.zip

This is the code that I am currently developping for that board

This has not been flyed yet. Only ground test

Note that the code for converting to feet is in this version. It can also beep the altitude digit by digit.

AltiDuoV1_4.zip

This is mainly some rework and tidy up code done by Kevin Ruland.

It also save the last altitude to an EEPROM. It has not been fly yet but should be pretty safe.

Adafruit-BMP085-Library In order to compile the code you need to get that file which is the sensor library

ATtiny environment patches for the Arduino IDE

WINDOWS+ld.zip Patched linker for the ATtiny. Use it because of a bug with the linker provided with the Arsuino development environment.
attiny.zip ATtiny hardware support need to be installed because it is not distributed with the Arduino framework
tiny.zip

I am now using a different implementation of the Attiny so that the tone function works for the altimeter this come from the following site

 

Common libraries for the ATtiny environment

tinyBMP085 This a modified version of the BMP085 sensor library
tinyWireM This is an implementation of the IC2 wire library
tinyWireS for the Attiny processor

 

Mini Alti Duo Files (Using an ATtiny 84)

AltiDuo_attiny84-V0.1.zip This is a port of the stable code of the altimeter Altimeter AltiDuo for the processor ATtiny 84. This has been tested.
AltiDuo_attiny84_filter.zip This one is the same program with a Kalman filter. This has been tested and should be the version to use.
AltiDuo_attiny84_filter1_2.zip This is the latest version with some bug correction
Mini Alti Duo kit build instructions-13-05-2013-eng.pdf Kit building instructions

 

Mini Alti Uno Files (Using an ATtiny 85)

AltiUno_attiny85-V0.1.zip This is a port of the stable code of the altimeter Altimeter AltiDuo for the processor ATtiny 85. This is experimental, a prototype has been built first tests are succesfull but this has not been fly yet....
AltiUno_attiny85_filter.zip This one is the same program with a Kalman filter
AltiUno_attiny85_filter1_2.zip This is the latest version with bugs corrected
Mini Alti Uno kit build instructions-14-05-2013-eng.pdf Those are the kit building instructions

Rocket Flight Logger

RocketFlightLogger.zip

This is a rocket flight logger. It stores data in an EEPROM and send them back to the computer. This has been tested on the ground and the work is currently experimental.

 

RocketFlightLoggerV1_0.zip This is a rocket flight logger. It stores data in an EEPROM and send them back to the computer. This can store up to 25 flights. It has 3 pyros output. All functionalities that are used in the altiDuo altimeter have been implemented.This has been tested on the ground and the work is currently experimental.
