bring up the serial example on PCA10056 board

[Bar]

I try to active the serial example in the nordic folder nRF5_SDK_15.2.0_9412b96. When using  RX_PIN_NUMBER 8, TX_PIN_NUMBER 6, CTS_PIN_NUMBER 7, RTS_PIN_NUMBER 5,  HWFC true.

I use the PCA10056 board.

1. Is the standard setting in the example demend the CTS, RTS and how can I change it only use RX,TX?

2. I didn't understand from the PCA10056 sechem where I can get those pins. I trace the line and found it enter U5 FSA2466UMX which control by U2 ATSAM3U2CA-AU. Is there a direct connect to those pins?

Thanks

That'll be the on-board JLink.

That includes a UART-to-USB converter, which connects the nRF52's UART to a virtual COM port on the PC.

The demo is intended to work with a terminal program on the PC, via the virtual COM port.

IIRC, it does require hardware flow control.

You should get this working first.

Then, if you want to connect direct to the nRF52's UART, you need to identify some free & accessible pins ...
