SPI device

nRF24L01+

The nRF24L01+ is an SPI device in the LabWired part catalog. Its catalog type is nrf24l01. It connects to the MCU over SPI. The catalog gives a supply range of 1.9–3.6 V. It has 8 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 register shell only; no 2.4 GHz RF packets.

How to simulate the nRF24L01+ in LabWired

Open the Playground at app.labwired.com and place an MCU board.
Add the nRF24L01+ (catalog type nrf24l01).
Connect VCC and GND to the supply and ground of the board. Use a supply inside the catalog range of 1.9–3.6 V.
Connect SCK, MOSI and MISO to the SPI pins of the board.
Connect CSN to the chip-select pin of the board, or to a free GPIO.
Connect CE to a free GPIO pin.
Connect IRQ as your circuit needs.
Run the firmware. It selects the part and moves bytes over the simulated SPI bus as on hardware.
