API (ECIO28P) component
Connects to an ECIO28P running the API Firmware allowing the board to become a slave to the Flowcode Embedded simulation or Flowcode App Developer. Supports: Digital IO / ADC / I2C / SPI / PWM / UART See Flowcode Help Wiki for firmware.

Detailed description
The App Developer (ECIO28P) component allows an ECIO28P board to be controlled from within the Flowcode simulation runtime.
To allow Flowcode to communicate and control the ECIO28P hardware the board must first be pre-programmed with dedicated firmware.
The firmware hex file and Flowcode source project can be downloaded from here.
ECIO28P App Developer Firmware
More information about the workings of the firmware project can be found on the FiniteStateMachine page.
The COM port to the ECIO hardware is selected via the SCADA_ECIO28P component COM port property.
When building the component into a App Developer project remember to expose the COM port property to allow the end user to select the correct port 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
