OpenPilot com stm32f103vet6, FreeRTOS e USB HID

O Openpilot é um projeto para criação de UAVs.
O projeto faz uso de microcontroladores STM32.



O modelo mais básico usa um stm32f103cb com 20kb de ram e 128kb de flash, um sensor mpu6050 e mais uma memória spi de 8mb para logs de vôo.
O software é baseado no FreeRTOS que é um RTOS de código aberto que apenas 3 arquivos C provê threads, mutex, queues, e muito mais. Também possui um bootloader que faz isso da porta USB como dispositivo HID.

Em teoria qualquer stm32 com configuração maior ou igual ao stm32f103cb pode rodar o software do Openpilot e sair voando por ai.

Comecei um teste usando o stm32f103vet6 que tem 64kb de ram e 512kb de flash, um sensor mpu6050, e removendo a memória spi de 8mb do projeto inicial.
Segue os passos do experimento feito no Ubuntu 14.04:

# obter o código fonte
git clone https://github.com/openpilot/OpenPilot.git
cd OpenPilot

------------------------------------------------------------------------------

1) No ubuntu

Instalar o GNU ARM embedded que é mantido pela própria ARM.
(ARM employees are maintaining this project.)

https://launchpad.net/gcc-arm-embedded

Step1: Inside Ubuntu, open a terminal and input
       "sudo add-apt-repository ppa:terry.guo/gcc-arm-embedded"
Step2: Continue to input
       "sudo apt-get update"
Step3: Continue to input to install toolchain
       "sudo apt-get install gcc-arm-none-eabi"


2) No ArchLinux

# instala o toolchain para cross compilar com o GNU ARM embedded
make arm_sdk_install

 no Archlinux é preciso habilitar o repositorio multilib e instalar o skype ou wine para instalar as lib32* que o U ARM Embedded depende.

# muda o path se necessário
export PATH=$PWD/tools/gcc-arm-none-eabi-4_8-2014q1/bin/:$PATH

------------------------------------------------------------------------------

#limpar tudo
21:16:11 murix@localhost:~/workspace/OpenPilot$make all_clean
 CLEAN      build

# gerar o firmware completo (bootloader+app)
21:17:07 murix@localhost:~/workspace/OpenPilot$make ef_coptercontrol

#gravar por SWD

STM32F103VET6 com Openpilot detectado como USB HID
Openpilot  Ground Control station (GCS)
bootloader reconhecido,
problema com o firmware que está resetando

Testando também o fork TauLabs (no Ubuntu 14.04 e no Archlinux)
https://github.com/TauLabs/TauLabs

# compila tudo
make package -j4
# gera imagem inteira da flash (bootloader+dados+app)
make ef_coptercontrol
# gravar a imagem no stm32f103vet6 com o stlink via SWD (pinos PA13 e PA14)
st-flash  write build/ef_coptercontrol/ef_coptercontrol.bin 0x08000000
# executa a ground control station
./build/ground/gcs/bin/taulabsgcs

Taulabs Ground Control station (GCS)
é um fork do Openpilot que tem mais placas e mais plugins.
O firmware para o stm32f103vet6 já ficou melhor, já está reconhecendo sem reboot,
porém nem o boot e nem o safeboot funcionaram ainda


Observações finais:

O Openpilot é muito bem estruturado.
Também é ótimo para quem quiser aprender a programar multi-linguagens (C, C++, Java).


A Control Ground Station (GCS) em Qt5 é muito completa e suporta plugins para estender ainda mais.

Também conta com Control Ground Station (GCS) para Android, então dá para pilot usando o telefone ou tablet pelo WiFi.

O firmware para placas STM32F1 (legado) e STM32F4 (atual),
contam com ajuda do FreeRTOS (que é um sistema operacional de real - RTOS - em apenas 3 arquivos),
também faz uso das placas USB configuradas como dispositivos HID,
possuem um bootloader com suporte USB.
O controle de vôo implementa um filtro estendido de Kalman (EKF) rodando a 500Hz é uma das melhores, senão a melhor solução conhecida.
