3. Nhazi

3.1. Mwepu na nyocha

Carefully remove the Arty A7-35T board from its packaging. Inspect the board for any visible damage. Ensure all components are securely attached.

3.2. Njikọ ike

The Arty A7-35T can be powered via the USB port or an external 7V-15V power supply connected to the barrel jack. For stable operation, especially when using power-hungry peripherals, an external power supply is recommended.

Connect the USB cable to the micro-USB port (J10) on the board and to your computer.
Alternatively, connect a compatible external power supply to the barrel jack (J12).
Ensure the power select jumper (J11) is set to the appropriate source (USB or EXT).

3.3. Nwụnye ngwanrọ

To develop and program the Arty A7-35T, you will need the Xilinx Vivado Design Suite. Follow the instructions provided by Xilinx for installation. Digilent also provides board support files na example projects for Vivado.

Download and install Xilinx Vivado Design Suite from the Xilinx websaịtị.
Install the Digilent board files for Arty A7, typically found on the Digilent website's resource center.
Ensure USB drivers for the JTAG programmer are correctly installed.

4. Ntuziaka ọrụ

4.1. Na-agbanye ike

Once connected to a power source, the power LED (LD11) should illuminate, indicating the board is receiving power. If using USB power, your computer should detect the device.

4.2. Programming the FPGA

The FPGA can be programmed using the Xilinx Vivado Design Suite via the onboard USB-JTAG mmemme.

Open Xilinx Vivado and create or open an FPGA project targeting the Artix-7 XC7A35T-1CSG324C.
Generate a bitstream (.bit file) for your design.
Use the Hardware Manager in Vivado to connect to the Arty A7 board.
Program the device with your generated bitstream.

The FPGA can also be configured from a Quad-SPI flash memory. Refer to Digilent documentation for details on programming the flash memory.

4.3. Using Onboard Peripherals

The Arty A7-35T includes several user-configurable peripherals:

LEDs (LD0-LD3, LD4-LD7): Eight user LEDs for visual feedback.
Switches (SW0-SW3): Four slide switches for digital input.
Buttons (BTN0-BTN3): Four push buttons for momentary input.
Reset Button (CK_RST): Resets the FPGA configuration.

These peripherals are connected to specific FPGA pins and can be controlled or read from your FPGA design.

4.4. Expansion Connectors

The board features Pmod connectors and an Arduino/chipKIT shield connector for expanding functionality with various modules. Ensure proper voltage levels and pin assignments when connecting external hardware.

5. Nlekọta

5.1. Nlekọta n'ozuzu

Handle the Arty A7-35T board with care to prevent damage from electrostatic discharge (ESD). Always hold the board by its edges. Store the board in an anti-static bag when not in use.

5.2. Nhicha

Ọ bụrụ na ọ dị mkpa, jiri ahịhịa dị nro ma ọ bụ ikuku a kpọnwụrụ akpọnwụ hichaa bọọdụ ahụ nke ọma iji wepụ uzuzu. Zere iji mmiri mmiri ma ọ bụ ihe ndị na-eme ka ọ dị nro.

5.3. Mmelite firmware

Periodically check the Digilent website for any firmware updates for the onboard USB-JTAG programmer or other components. Follow the provided instructions carefully for any update procedures.

6. Nchọpụta nsogbu

6.1. Okwu Ike

No Power LED (LD11): Check power source connection (USB or external adapter) and ensure the power select jumper (J11) is correctly set. Verify the external power supply provides 7V-15V.

6.2. USB Connectivity Problems

Board not detected by computer: Ensure USB cable is securely connected. Try a different USB port or cable. Verify that the necessary USB drivers for the Digilent JTAG programmer are installed on your computer.

6.3. FPGA Programming Errors

Vivado Hardware Manager cannot find device: Confirm USB connection and driver installation. Ensure the board is powered on. Check that the correct device (Artix-7 XC7A35T) is selected in your Vivado project.
Programming fails: Verify your bitstream is correctly generated and compatible with the Artix-7 FPGA. Ensure no other software is interfering with the JTAG njikọ.

6.4. Unexpected Behavior

Design not functioning as expected: Review your HDL code and constraints. Use Vivado's debugging tools (e.g., ILA, VIO) to inspect internal signals.
Board becomes unresponsive: Press the CK_RST button to reset the FPGA configuration. If issues persist, power cycle the board.
