How to simulate the 74HC595 Shift Register (8-bit output) in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the 74HC595 Shift Register (8-bit output) (catalog type 74hc595).
  3. Connect GND and VCC to the supply and ground of the board.
  4. Connect SRCLK and SER to the SPI pins of the board.
  5. Connect RCLK to the chip-select pin of the board, or to a free GPIO.
  6. Connect OE and SRCLR to free GPIO pins.
  7. Connect QB, QC, QD, QE, QF, QG, QH, QA and QH' as your circuit needs.
  8. Run the firmware. It selects the part and moves bytes over the simulated SPI bus as on hardware.
