==API (RPI) component==
Connects to a Raspberry Pi running the API Firmware allowing the board to become a  slave to the Flowcode Embedded simulation or Flowcode App Developer. Supports: Digital IO / I2C / SPI / PWM / UART See Flowcode Help Wiki for firmware.

==Component Source Code==

Please click here for the component source code: [https://www.flowcode.co.uk/wikicopy/componentsource/FC_Comp_Source_RPI_API_Comp.fcfx FC_Comp_Source_RPI_API_Comp.fcfx]

==Detailed description==













The App Developer (RaspberryPi) component allows an Raspberry Pi to be controlled from within the Flowcode simulation runtime. 

To allow Flowcode to communicate and control the Raspberry Pi hardware the board must first be pre-programmed with dedicated firmware.

The firmware file and Flowcode source project can be downloaded from here.

{{Zip|RPI_SCADA_Firmware.zip|RPI App Developer Firmware}}

More information about the workings of the firmware project can be found on the [[FiniteStateMachine]] page.


The IP Address to the Raspberry Pi hardware is selected via the SCADA_RPI component IP Address property.

When building the component into a App Developer project remember to expose the IP Address property to allow the end user to select the correct address for the hardware.


The console window can display data in two modes which is set via a component property.

*fixed statistics showing IO / ADC inputs / PWM
*scrolling log showing all commands and returns
