Bodacs

Le Bodac est un montage qui permet de mettre en oeuvre plusieurs boutons sur une seule entrée analogique, tout en ayant la possibilité de les avoir appuyés en même temps. Le montage est simple : une résistance entre chaque borne des boutons, et un seul fil entre chaque bouton.

Ce pack de résistances de précision 1%, permet de réaliser un Bodac pour 5 boutons ou moins.

IO Headers

Les supports IO permettent d'éviter de souder directement sur la carte, évitant ainsi les courts-circuits. Vous pourrez connecter vos boutons/encodeurs/etc avec des câbles dupont. La carte sera fournie avec les supports déjà soudés.

Firmware

En choisissant un package NodeBlue, vous bénéficiez de la configuration de votre choix. Un formulaire de configuration vous sera envoyé après votre commande afin de préciser la programmation souhaitée. Ce formulaire est similaire à cette page, qui permet de tester si la configuration est possible. La carte sera programmée et testée en conséquence, et les schémas de câblage vous seront fournis. Si vous ne prenez pas de package, vous devrez programmer la carte vous même avec l'IDE Arduino. Plus d'information sur les différences entre le package standard et le package pro sont disponibles sur cette page.

The 5v is available around the serial port to connect a Nextion screen or a 7-segment display. The 5v is also exposed to connect RGB leds. Screen and leds are managed with SimHub software.

 

The following connectors are also proposed :

  • A 4-pin JST 2.0 connector to easily connect an aviation connector.
  • A USB-C connector to program the board or connect a USB extension.
  • A 2-pin JST 2.0 connector with 5v to power permanently button leds for example.

 

If you choose a customized firmware option, NodeBlue package is included with the board, so you can have any configuration you need. A configuration form will be sent after your order, so you can specify the desired programming. The board will be programmed accordingly and the wiring schematics will be provided.  You can check here if your configuration is possible.

Axis Calibration
To reprogram the board or to calibrate the axis, you need to install Node Blue. It is recommended to reprogram the board to benefit from the latest version.
Depending on the project you are using, you will have to use one of the following 2 methods:
  • Calibration with the serial monitor
You will need to have a  “NodeBlue Interface”, “SimHub Interface” or “Nextion Interface” module in your project.
Attention : if the USB port is used for a Nextion, leds or other Simhub interfaces, you’ll need to disconect SimHub in order to free the serial COM port.
In Node Blue, open a serial monitor on the board (at the top of the window, select the correct COM port and click on the # icon), You can see the calibration messages in the serial monitor (window at the bottom in Node Blue). You must also display the “Controllers” tab at the top right. Select “Raw” as display mode.
For each axis:
  • Click on the “Cal” input of the analog input module, the sensor module (eg AS5600) or the “Range” module. The module name can be “Accel”, “X”, “Y” or “Z”, or something else depending on the application. Once cal is pressed, a message appears in the serial monitor window. Follow the instructions.
  • Once the calibration is complete, double click on the module to change the low and high deadband parameters. Check in the controller tab that when the axis is completely released the value is 0 and when it is fully released the value is 65535. Adjust the dead zones if necessary. Click on “Invert” if you need the axis to work in an inverted way.
Once the calibration of all axis is complete, save the project so that the settings are saved, either by using the “Save project” menu or with the CTRL-S key combination. If the project is read-only, use the “Save As” menu and choose another name.
  • Manual Calibration (if the USB Virtual serial port is not present or used by another non compatible module)
In the “Controllers” tab at the top right. Select “Raw signed” as the display mode.
For each axis:
  • Double-click on the analog input module “X”, “Y” or “Z” (or any other name depending on the project) concerned by the axis.
  • Position the axis to the minimum, copy the value displayed in the controller tab (adding a small margin), in the “In Min” parameter of the module.
  • Position the axis to the maximum, copy the value displayed in the controller tab (by removing a small margin), in the “In Max” parameter of the module.
  • change the low and high deadband parameters. Check in the controller tab that when the axis is completely released the value is 0 and when it is fully released the value is 65535. Adjust the dead zones if necessary.

 

Once each axis has been done :

  • Save the project so that the settings are saved, either by using the “Save project” menu or with the CTRL-S key combination. If the project is read-only, use the “Save As” menu and choose another name.
  • Select the com port among those detected (disconnect any other detected boards to be sure to program the board you want).
  • Upload the project to the board (“Upload” button).

 

The settings are saved in the flash memory of the board and are restored at each restart.
