74HC595 7-Segment (4-digit)

The 74HC595 7-Segment (4-digit) is an SPI device in the LabWired part catalog. Its catalog type is hc595-7seg. It connects to the MCU over SPI. The catalog gives a supply range of 2–6 V. It has 5 pins. A registered peripheral model runs in the engine: the firmware talks to it over the real bus and gets device-accurate responses.

How to simulate the 74HC595 7-Segment (4-digit) in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the 74HC595 7-Segment (4-digit) (catalog type hc595-7seg).
  3. Connect GND and VCC to the supply and ground of the board. Use a supply inside the catalog range of 2–6 V.
  4. Connect SCLK and DIO to the SPI pins of the board.
  5. Connect RCLK 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.
