Examples
Here is a simple example showing how to pass data from a device such as an Arduino back into Flowcode for debugging purposes. The example is designed to run on an Arduino Uno R3 with an LED connected to pin D2 and a potentiometer connected to pin A0. The program loops switching the LED on and off and reporting the status to the console, the ADC is also sampled as a voltage string and this is also passed back to the console.
The incoming data can be seen on the Flowcode console even when the simulation is not running.
Outgoing data can be sent back to the embedded hardware by typing data directly into the RX Queue tab of the console.

Properties |
|
COM Port |
| Selects which port to communicate with, only lists ports which are currently available. | |
|
Refresh COM Ports |
| When set to yes the COM port list is rescanned for newly connected or available ports. Note that refreshing the ports list may take a few seconds depending on the number of connected ports. | |
|
Baud |
| Baud rate passed to the COM port to control the rate of data. | |
|
|
Connection Type |
| Decides how to work with the COM port. Manual - Port needs to be manually opened and closed by the user. Port may become locked if left open. Port is automatically closed when programming. Automatic - Port handling is automatic but port may be left open when closing the project. Port is automatically closed when programming and reopened after 20 seconds. | |
|
|
Connection |
| Port connection status. Closed - Port is unavailable and not in use. Open - Port is available for data communications. | |
