API (BL0032) component
Connects to an BL0032 dsPIC 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 / UART / PWM See Flowcode Help Wiki for firmware.

Detailed description
The App Developer (BL0032 dsPIC E-Block) component allows an BL0032 dsPIC E-block board to be controlled from within the Flowcode simulation runtime.
To allow Flowcode to communicate and control the Arduino Uno hardware the board must first be pre-programmed with dedicated firmware.
The firmware hex file and Flowcode source project can be downloaded from here.
BL0032 dsPIC App Developer Firmware
More information about the workings of the firmware project can be found on the FiniteStateMachine page.
The USB should be connected to the Target port on the E-block board to allow Flowcode to communicate with the Target microcontroller.
The COM port to the E-block hardware is selected via the SCADA_BL0032 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.
