I'm not sure I'm using the uart code correctly in my program. The data ready function is not returning a 1. Is the uart setup right?

Hi,

Please, can you explain me a little bit more where the problem occurs?
How you test your project/code?

UARTx_Data_Ready() function tests if data in receive buffer is ready for reading and return 1 if data is ready for reading,
which means that if you send some character over UART, UARTx_Data_Ready() will be set to 1,
when is detected that you have some data in receive buffer (character which you send).

Thanks for you're response. I've hooked up a speech board to a pic clicker board. I've programmed the speakup board with three entries which return a 1, 2 or 3. However, the speech board is not sending data when I talk to the board. Should it?

Hi,

SpeakUp click should send a index of the recognized word over UART if you use the SpeakUp click in "click" mode
(if you connected UART lines from mikroBUS socket).
To see in which format SpeakUp return recognized word, you can simple connect SpeakUp click over some USB UART board with the PC and watch received data in USART Terminal.

How do you setup "click" mode. I dont see any reference to this in the software. Also, do you setup communication as uart or usb?

Hi,

SpeakUp application can be used with SpeakUp click only in stand-alone mode.
Click mode means that you connect SpeakUp click with your hardware over mikroBUS socket,
which means that you connected proper UART lines .
Trough UART you can "read" a index of the matched voice command from SpeakUp click.

Hello!

I'm having this same issue, and it looks like someone posted about this back in May 2014 as well. I'm seeing "READY" show over the UART serial line, but no command indexes for recognized voice commands. Is there a newer firmware for the "speakup click" module, or something more we can do to get this working? I have confirmed my hardware serial rig is working properly with the "READY" test, and with other microcontrollers.

Thanks,
David

Hi,
