Arduino

Introduction

Some Arduino related stuff.

Use e.g. Cool Term Win to save logged terminal data from serial monitor. The serial monitor need to be closed during the recording.

J2 and J3 are not connected, you can program the Arduino.
J2 (and J3) connected: you can transmit data through the radio.
J4 (and J5) connected: you enable data storage in the MicroSD-card.
J6 connected: the EN pin on the APC220 radio module is connected to the digital port D7 on the Arduino.
J7 or at J8 or both in order to connect power to the Gy-87/88/91.

Cansat Version 7

Cansat Version .... This version has MPX4115A pressure sensor.

Check the pins while uploading, saving or using memory card.

Not found. . . Remove the pins.
1. CanSat-laajennuspiirilevyssä on oikeanpuoleisen kuvan mukaisesti kaksi hyppyjohdinsarjaa, J2 ja J3.
2. Kun J2- ja J3-hyppyjohtimia ei ole kytketty, voit ohjelmoida Arduinoa.
3. Kun asetat hyppyjohtimet kohtiin J2-1 ja J2-2, voit lähettää tietoja radiolla.
4. Kun asetat hyppyjohtimet kohtiin J3-1 ja J3-2, voit ottaa käyttöön tietojen tallentamisen SD-kortille (jos se on kytketty).
