CLEANING ON WAY

under reconstruction as always

Jens

KRNL a small preemptive kernel (previous known as snot)
HDLC byte stuff protocol for frame based communication
CRC16 package for calculation and verification (can be used together with hdlc)
A simple PID controller - you must provide timing
A morse package - Morse by sound (tone) or hi/lo - full configurable

AAU CANSAT

UNDER MOD AND UPDATE

Will be at http://jensd.dk/space/cansat

About the new i2c pressure sensor which can be used instead of mpx4115. It has higher sensitivity.

The library supports range switch between 1.5g and 6g - by D8 or you can choose another pin.

A small wire has to be added to the shield.

bmp085 pressure transmitter - (i2c)adapted from …
configuration tool for apc220 radio
mma7361l a new 3 axis library library
- calib15g6g is a calibration program which will give numbers to be used
- xyz15g6g for an example with range switch
10k ntc a steinhart-hart based ntc 10 k temp sensor converter
xyz is a small program for mma77361l . Use library above

A cansat setup

A small setup with an Arduino Mega (1280/2560), DY-80sensor board and Fasttrax up-501 GPS has been setup

Seen from top. from left to to right: openlog, dy-80 sensor board, up-501 gps

Missing APC-220 radio on top

The top green shield is our normal cansat shield vrs 2 now with mpx4115 etc and instead the DY-80 board.
The DY-80 which is 10 DOF (degr of freedom): adxl 345 , l3g4200 hmx5883l all i2c interfaced
and gives you 3 axis acc, gyro, magnetometer and pressesure and temperature

You can find code in the sketches section here

If you have nosiy signals filtering may be an idea. See filter

oOoOo

Real time Kernels

I have written a preemptive kernel for Arduino - SNOT - and have also FreeRTOS

See kernels for more info and src

REMEMBER : all is free and under the beer license. Feel free to use and if you do send me an email.

Everything is as it is including all possible errors in the code. So yo are on your own.

SNOT is tested a lot so I hope (but cant and will not promise) it should be reasonable error free
