Protocol Hot Swapping Between Multiple UART Lines

[Ryne Horn]

Hello,

So I am trying to write a script that will be taking advantage of both output and both inputs to the AD2 as well as take select information and send it out to two (for now) serial lines.  I have written a script to control everything I need minus the actual setup of the UART settings, sending the data over the Tx line and receiving over the Rx line. Are there any examples of how to send the data over script as opposed to using the built-in GUI of Waveforms?

Thanks,

Ryne

Hi @Ryne Horn

The WaveForms application Script lets you send data over TX but there is no function to receive data, yet...
Protocol.UART.Send("Hello")

The WF SDK beta version adds functions for UART and CAN TX/RX, SPI and I2C master:

Nice! Thank you @attila !

Looks like I nearly have it working but when I use this "Send" command it does not append the ending (i.e. Carriage Return).  How do I go about adding this to each command I "Send"?

 

EDIT: I found it.  TO either include or not include the ending you need to put Protocol.UART.Send("Hello", true) or Protocol.UART.Send("Hello", false), respectively.

Hi @Ryne Horn

In case you need it, WF beta v3.7.22 adds Receive functions for UART.
