2. Installatie en eerste configuratie
To begin using your Zybo Z7-10 development board, follow these steps for proper setup:
- Stroomaansluiting: Connect the board to a power source using either the USB port or a 5V barrel jack connector. Ensure the power supply meets the board's requirements.
- USB-verbinding: For communication with a host computer, connect the board via a USB cable to an available USB port. This connection is typically used for programming and debugging.
- Video-uitvoer (optioneel): If your application requires video output, connect an HDMI display to the board's HDMI TX port.
- Audioverbindingen (optioneel): For audio input or output, connect appropriate audio devices to the MIC IN, LINE IN, or HPH OUT (headphone out) jacks.
- Pmod Connectors (Optional): Utilize the six Pmod connector ports for expanding functionality with various peripheral modules.

3. Operating the Board
The Zybo Z7-10 offers various on-board user interfaces and extensive I/O for development:
- Gebruikersinterfaces: The board includes 6 push buttons, 4 slide switches, 5 LEDs, and 2 RGB LEDs for direct user interaction and status indication.
- FPGA I/O: Over 30 FPGA I/O pins are available for custom connections and interfacing with external circuits.
- Analoog-naar-digitaal conversie: Four analog-capable 0-1.0V differential pairs connect to the XADC, enabling analog signal processing.
3.1. FPGA Programming
The Zynq-7000 AP SoC on the Zybo Z7-10 can be programmed via JTAG for volatile configuration or through the on-board QSPI flash memory for non-volatile storage of your designs. Development typically involves Xilinx Vivado Design Suite.
For detailed programming instructions and examples, refer to the official Digilent documentation and tutorials available on their webplaats.
