Actually, controlling the display is a mix of a number of packages and tutorials.

Following the display bus tutorial, to run the simple test example from CircuitPython Display IO Layout.

So, on the Adafruit FT232J board (the I2C mode is still off!), I should connect the green to GND (two options), the red wire to 3V, the orange to D0 and the yellow wire to D1.

Connect the green wire to GND, the red wire to VCC, the orange to SCL and yellow wire to SDA. It is specified how the 4 I2C pins should be connected to the Raspberry Pi GPIO pins.

Looked up the recommended display driver.

Also note Microsoft's BrainCraft HAT, which also has the STEMMA connectors.

Note that there also exists a RaspberryPi Hat for Lego robotics, including Lego compatible case.

Even better, a RasberryPi compatible GPIO proto-board, with cable GPIO cable and some Jumper wires.

Maybe handy to also add Adjustible powersupply.

When playing with a breadboard, regulating the voltage back to 3.3V is recommended.

The same I2C and SPI ports are available on Raspberry PIs, Jetsons and Coral TPU Dev Boards.

With Male Headers cable, you could easily connect to an i2c board, as the i2c-led display of the nanosaur.

The Adafruit board has also a Stemma Qt connector, which has several compatible sensor, including two thermal sensors.

Running ros2 launch -s pal_camera pal_ shows the available arguments that could be given to the launch file.

So, with the argument camera_name:='/dreamvu/pal3/' this name is used for the namespace, but not for as argument.

: The parameter 'general.camera_name' was available and set to the value: /dreamvu/pal/

Strange, now it seems to work with the values from the launch file:.

Run the node with ros2 launch pal_camera pal_.

The rviz_plugin_plugin_zed keeps on failing on missing rviz_rendering_extras, so build only the pal_camera node with -packages-select:Ĭolcon build -symlink-install -cmake-args=-DCMAKE_BUILD_TYPE=Release -packages-select pal_camera.

A simple pip3 install lark solves this issue. Yet, now the rosidl_generator_cpp fails on missing lark package.

The cmakefile.txt was modified, so run colcon with argument -cmake-clean-cache.

Node also has the option to list the parameters: see this example.

The call get_parameters is a method from Node.

Start with an update, to get the latest versions of the rox-foxy packages.

Trying to debug the get_parameter problem of the dreamvu_camera_node.

According to rviz, the topic /dreamvu/pal/pal/get/left is published (indicated pal as name, which is added to the namespace), also only the map and base_link are available, no tf is published between the baselink and the camera_center. I will submit a temporary 'working' version, and then put all configuration into the yaml.

On the other hand, overriding doesn't seem to work.

The value is red, the camera_name is now pal4.

The zed_wrapper is not only launched with the launch argument camera_name, but also with the config_camera_path, which contains a yaml which declares general.camera_name.My function declares a parameter before reading it, maybe I shouldn't.The FT232H switches off when connected with breakout wires.

AdaFruit has an extensive manual for its FT232H board.
