- Adjust settings to match the SPI slave device's specifications (clock polarity, phase, bit order, SPI mode, and slave select line).
- Ensure the FPGA design exposes the SPI interface correctly (SCLK, MOSI, MISO, SS) and can handle the SPI protocol as per the SPI WriteRead block's configuration.
- For hardware FIL, make physical SPI connections between the FPGA board and the Simulink host.
- For simulated FIL, ensure the simulated environment accurately emulates the SPI behavior.
- Start with basic operations to verify communication, using scopes or logging to monitor data. Adjust timing as needed for reliability.
- Integrate the SPI communication into the larger system model, testing under various conditions to ensure robust operation.
Can I used hte Spi WriteRead Block with just any SPI device or should it be only with arduino

I have a SPI slave device which is modeled in Simulink via the FIL ( FPGA in LOOP) approach. Would it be possible to use the SPI WriteRead Block available to communicate to this model ?

Hi Mayur,
To communicate with an SPI slave device modeled via the FPGA-in-the-Loop (FIL) approach using Simulink's SPI WriteRead block, follow these steps:
In summary, successful communication via the SPI WriteRead block with an SPI slave in FIL requires careful configuration of both Simulink and FPGA settings, appropriate setup of the simulation or hardware environment, and thorough testing and debugging to ensure reliable operation.
