Description
RGB Extension add-on
While the evaluation board itself contains all key components plus the RiBUS interface to EVE displays – the RGB extension header brings the interface to most of Riverdi RGB displays.
The evaluation board can use either RiBUS to drive the display with EVE graphics controller or the RGB extension. An add-on board, apart from delivering signals to the display, plays a role of a physical carrier to the whole module. Therefore, add-on boards must be customized to the displays they are serving.
Because of STM32F469II resolution limitation, it is currently possible to connect 10.1” displays only via RiBUS – so they must be models with BT817Q controller.
Mechanical functions
Don Addon 5 RGB is a stable mechanical base for three components:
• STM32 Evaluation Board,
• 5″ RGB TFT display
• The add-on board itself
Mechanical stability of the above devices fixed together protects delicate TFT connectors against breaking, tearing off and wearing out due to frequent connecting and disconnecting.
Don Addon is designed in a way that allows the use of all three in horizontal and vertical positions. The horizontal position is particularly useful during development. It gives a secure access to STM32 Evaluation Board measuring terminals and other circuitry points desired by a developer white the vertical position allows for hanging the entire working unit on a vertical post for exhibiting purposes and for drawing visitors’ attention.
A TFT module is fastened to the add-on board with velcro tapes in five corners of the module. Using velcro tapes between the add-on board and the TFT ensures a relatively strong fastening to make sure the TFT connectors are safe from mechanical damage in both positions, and also makes swapping of the TFT modules fast and easy.
