SPI device

microSD (SPI)

The microSD (SPI) is an SPI device in the LabWired part catalog. Its catalog type is microsd. It connects to the MCU over SPI. The catalog gives a supply range of 2.7–3.6 V. It has 6 pins. A registered peripheral model runs in the engine: the firmware talks to it over the real bus and gets device-accurate responses.

From the catalog: SPI CMD shell; CMD17 returns zeros — no filesystem.

How to simulate the microSD (SPI) in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the microSD (SPI) (catalog type microsd).
  3. Connect VCC and GND to the supply and ground of the board. Use a supply inside the catalog range of 2.7–3.6 V.
  4. Connect SCK, MOSI and MISO to the SPI pins of the board.
  5. Connect CS to the chip-select pin of the board, or to a free GPIO.
  6. Run the firmware. It selects the part and moves bytes over the simulated SPI bus as on hardware.
