  • Page 7: Introduction

    Introduction 1. Introduction The Panel-Card is intended to be used as a small and medium size "intelligent" display module as well as a universal Linux CPU card. It can be used where restricted energy and space requirements play a role. It comes in different sizes and variations, but the connector keeps the same, likewise the center of the LCD/TFT.

  • Page 12: Hardware Description

    The Panel-Card can such be placed even on a standard 0.1" pitch breadboard. The size of the Panel-Card's PCB and the location of its mounting holes is adapted to the mechanics of standard 93x70mm LCDs, so the Panel-Card can easily be mounted in any enclosure which is prepared for such LCDs.

    4.12. Timer Counter (TC) The Panel-Card features one block of timer counters with three counters. None of them is available on the connectors. You can only use them internally. The TC consists of three independent 16-bit Timer/Counter units. They may be cascaded to form a 32-bit or 48-bit timer/counter.

  • Page 18: Watchdog Timer

    Hardware Description 4.14. Watchdog Timer The watchdog timer is a 12-bit timer running at 256 Hz (Slow Clock / 128). The maximum watchdog timeout period is therefore equal to 16 seconds. If enabled, the watchdog timer asserts a hardware reset at the end of the timeout period. The application program must always reset the watchdog timer before the timeout is reached.

  • Page 19: Debug Unit (Dbgu)

    The Panel-Card features two Multimedia Card Controller, of which MCI-A is externally available on the connectors. On the Evaluation Board of the Panel-Card 35, it is connected to the SD/MMC-Card slot. Please note that operating systems like Linux do not necessarily support all features of the hardware unit.

    SD and MultiMedia Cards are the initialization process and the bus topology. 4.20. USB Host Port (UHP) The Panel-Card integrates two USB host ports supporting speeds up to 12 MBit/s. The USB Host Port (UHP) interfaces the USB with the host application. It handles Open HCI protocol (Open Host Controller Interface) as well as USB v2.0 Full-speed and Low-...

The PDC provides chained buffer management without any intervention of the processor. Six different modes are implemented within the USARTs: •...

  • Page 22: Synchronous Peripheral Interface (Spi)

    The Panel-Card features two externally available SPI ports, each with three chip selects. Be aware that on the Panel-Card 35 when connected to the Evaluation Board and on the Panel-Card 57/70 all chip selects of the second port are already used. To compensate for this, you can also use GPIO pins as chip selects with the Linux SPI driver.

    Hardware Description Accordingly, the LCDC should not be powered down without deactivating the LCD supply voltage. The same is true if the LCDC is stopped indirectly by stopping the respective clock source, namely the PLLA. The LCD backlight supply is not involved in these considerations. It may switched on or off at any time independently of the state of the LCDC.

  • Page 25: Display (Tft)

    PC10. 4.27. Touchscreen The Panel-Card 35 is available with a touch. However, it does not have a touch controller on board, so it has to be implemented on the base board. A reference implementation with an ADS7843 touch controller can be found on the Panel-Card Evaluation board.

  • Page 26: Design Considerations

    Design Considerations 5. Design Considerations 5.1. USB Host Controller (UHP) External Parts.  A few external parts are required for the proper operation of the UHP: • Pull-down resistors on each line of approximately 15 kΩ. These should be installed even if the UDP is not to be used at all in order to keep the signals from floating.

  • Page 27: Ethernet Controller

    Design Considerations • ESD protection devices are recommended for applications which are subject to external contact. The restrictions with regard to capacitive loading have to be applied when selecting a protection device. The USB specification (revision 2.0 of April 27, 2000, chapter 7.1.1.1) demands a cable with a characteristic impedance of 90 Ω...
