Serial Communication (UART)
The UART is a serial asynchronous communication module to communicate with an external device
such as a GPS receiver.
You must know the baud rate of the signal or the UART will not be able to work properly.
Flyport has a UART input buffer of 256 characters that stores the incoming chars. You don't have to
poll the UART buffer, but just check the number of received chars.
The size of the UART input buffer is customizable by the user, using the Wizard tool inside the IDE:
Warning: the maximum memory used by UART buffers should not exceed 6144. The Wizard tool will
show the effects of UART buffer size on total memory available.
To perform testing on UART we suggest PC programs like “Putty”, “Termite” or the IDE Serial Monitor.
Do not use Hyper Terminal because it does not support the DTR signal (that is used by miniUSB
programmer as Reset signal).
