Stage Camera Thermique 2022 @ Elsys Design

2022 thermal camera internship

About The Project

The goal of the "Caméra Thermique" internship is to design and implement a thermal camera with all the electronics and software that comes with. The final product shall embed the features listed below :

• a thermal camera for IR imaging,
• a daylight camera to compare the output with the IR image,
• a touchscreen to view the camera results, change display mode and take screenshots,
• an USB port to charge and communicate with the PC,
• a battery for the autonomy,
• an UART port to exchange debug messages,
• a SD card interface to save the screenshots,
• an external RTC to get the time more accurately than with the mcu integrated RTC,
• a SWD/JTAG port for programming/debugging purposes

What will you find in this repository ?

You'll find here all NuttX sources for both the integration and developement parts. However, from the official repo some changes have been made to meet our needs. Among them :

• The nuttx-src/apps folder contains an example named "thermal_camera". This is the main app of our project and it is the entrypoint for both the dev and final target
• The Nuttx nuttx-src/nuttx/boards/arm/stm32h7 folder contains a custom board to support our final target stm32h743vit6-ct2022.
• The nuttx-src/nuttx/drivers folder contains custom drivers such as the one for the thermal camera.

You will also find in this repository :

• some notes and the projects used to test the stm32H743vit6-ct2022 board under documentation/integration,
• hardware documents under document/hardware,
• some wiring schematics under documentation/wiring,
• images of the project under /images,
• docker files to build the nuttx environnement on your machine. s

Build NuttX Environnement With Docker Image

Step 0 - Prerequisities

You need docker-compose to build your docker image :

sudo apt install docker-compose

Step 1 - Build Docker Image

In the directory where 'Dockerfile' is located (should be at the root of this repo), run :

docker-compose build

(By default, the parent image is Ubuntu 20.04).

Step 2 - Build NuttX Environnement

In the directory where 'docker-compose.yml' is located (should be at the root of this repo too), run :

docker-compose run nuttxspace

If everything's fine, you should be inside the nuttx-src folder.

Build NuttX Environnement Without Docker Image

To build the NuttX environnement on a Linux-based system, install the following packages :

sudo apt install \
bison flex gettext texinfo libncurses5-dev libncursesw5-dev \
gperf automake libtool pkg-config build-essential gperf genromfs \
libgmp-dev libmpc-dev libmpfr-dev libisl-dev binutils-dev libelf-dev \
libexpat-dev gcc-multilib g++-multilib picocom u-boot-tools util-linux \
gcc-arm-none-eabi binutils-arm-none-eabi 

NuttX configuration system uses KConfig which is exposed via a series of interactive menu-based frontends, part of the kconfig-frontends package.

• For Ubuntu 20.04 and later :

apt install kconfig-frontends

• For older Ubuntu releases :

git clone https://bitbucket.org/nuttx/tools.git
cd tools/kconfig-frontends
./configure --enable-mconf --disable-nconf --disable-gconf --disable-qconf
make
make install

For any issues, please refer to the Official NuttX Installing Page.

Build NuttX Image

Step 1 - NuttX configuration

To configure Nuttx with a specific <CONFIG> and a specific <BOARD>, run from the nuttx-src folder :

cd nuttx
./tools/configure.sh <BOARD>\<CONFIG>

Usage :

./nuttx/tools/configure.sh stm32h747i-disco\thermal_camera`

Step 2 - Compile NuttX

Simply :

make
