Hardware test

The purpose of the hardware test is to make sure that the Flight Controller board performs as intended and that all the chips are 100% working.

Requirements

• 2x Flight Controller boards (v1.0) with:
  • T:
    • 1x RFM96W LoRa transceiver
    • 1x 433 MHz SMA antenna
    • 1x Teensy 3.6 microcontroller with 5V & VUSB isolated
    • 1x Arduino nano microcontroller (not used yet)
    • Two MS5611 / MPU9250 breakout boards
  • S:
    • 1x Teensy 3.6 microcontroller
• 1x JST-GH / JST-GH 8 pins cable (with wire 5 disconnected)
• 1x JST-GH / JST-GH 6 pins cable (with wires 2&3 inverted)
• 1x micro USB to USB cable
• 1x mini USB to USB cable
• 1x 2S LiPo battery with an XT-30 connector
• 1x 3S LiPo battery with an XT-60 connector

ALWAYS connect an antenna on all boards that have a Lora chip (U3)

Teensy

Sources :

test/hardware_test_teensy/ -> used to test all the I/O
src/test_companion_teensy.cpp -> used to help test the data links, works on a secondary board

Setup

Let's call the board to test 'T' and the secondary board 'S'

• Connect 'S' to your computer with the micro USB cable
• Upload the companion code on 'S' using the platformio shell

platformio run -t upload -e teensy_test

• Disconnect the micro USB cable from 'S'
• Connect 'S' and 'T' (only one at a time):
  • with the JST-GH 8 pins cable on J6 [to test the CAN bus]
  • with the JST-GH 6 pins cable on J1, J2, or J3 [to test the Serial ports]
• Connect the 2S LiPo to 'T'
• Connect the 3S LiPo to 'T'
• Connect 'T' to your computer with the micro USB cable
• Upload the test code on 'T' using the platformio shell

platformio test -e teensy_test -f hardware_test_teensy
# or
platformio test -e teensy_test_silent -f hardware_test_teensy # no buzzer sound

• Look at the output in the terminal

What is tested ?

Currently:

• MS5611
• RFM96W
• CAN Bus
• Serial ports
• Buzzer
• RGB Leds
• Parachute outputs
• Mosfet for J2 power line (Telemetry modem)
• Mosfet for J4 power line (FPV)

Missing:

• MPU9250
• NEO M9N
• I²C
• Flash memory
• Interrupts for liftoff detection
• Temperature sensors

Arduino nano

Sources :

test/hardware_test_nano/ -> used to test all the I/O

Setup

Only one board ('T') is needed

• Connect the 2S LiPo to 'T'
• Connect the 3S LiPo to 'T'
• Connect 'T' to your computer with the mini USB cable
• Upload the test code on 'T' using the platformio shell

platformio test -e nano_test -f hardware_test_nano

• Look at the output in the terminal

What is tested ?

• Buzzer
• Parachute outputs

Software test

TODO: make the embedded software compatible with unit testing and write unit tests for it
