Simple Interface Board Demo

Rapid Development - Virtualised SPI

A feature of the App Developer Slave interface is to use the component for rapid development.

The App Developer Slave hardware can be used to take communications from the Flowcode simulation and transfer them to a real world device allowing for easy code generation and test without having to download to a target microcontroller device.

The CS pin and SPI Prescaler are set via the properties of the Injector component.

The SPI Master component is linked to the Injector component via the Injector property.

The Injector component is linked to the App Developer Slave component via the App Developer Slave property.
