WICED SDK uart debug


#1

Hi all,
I need to debug my RedBear duo WICED application and I don’t have RBlink board.I can’t found any doc or code showing how to setup uart1 or uart2 for WICED SDK.Any help? Thanks a lot

Hi @msam,

Since the WICED SDK has not implemented the USB CDC, you can not print debug message via the Duo’s native USB connector. Unless you have a USB-UART bridge, then you can print the debug message via UART1 or UART2.

Please let me know if you have a USB-UART bridge so that I can tell how to print debug message via UART.

Thanks!

Good!

Please connect the USB-UART bridge with Duo as below:

Duo — USB-UART bridge

TX — RX
RX — TX
GND — GND

Open a serial terminal (e.g. PuTTY or Tera Term) and open the comport for your USB-UART bridge. Set the baudrate to 115200.

When your Duo run up, you can see the debug message printed on serial terminal.

Cheers!
