Sample UART code to use P0.17 and P0.19 that connects to a Microchip board (SAML10)

[windychicago]

Dear Sir/Madam

We are planning to use P0.17 (RXD ) and P0.19 (TXD) as serial communication port connecting to Microchip SAM L10 Xplained Pro - Dm320204. I wonder if there is any sample code or UART driver available for nRF52832?

Thanks

I found following code in file pca10040.h

// serialization APPLICATION board - temp. setup for running serialized MEMU tests
#define SER_APP_RX_PIN 23 // UART RX pin number.
#define SER_APP_TX_PIN 24 // UART TX pin number.
#define SER_APP_CTS_PIN 2 // UART Clear To Send pin number.
#define SER_APP_RTS_PIN 25 // UART Request To Send pin number.

However, when I search the entire solution, no where uses it.  Is there other place define them? 

Thanks

The LIBUARTE example uses the default UART pin configurations from the board header file:

//From main.c

nrf_libuarte_async_config_t nrf_libuarte_async_config = {
        .tx_pin     = TX_PIN_NUMBER,
        .rx_pin     = RX_PIN_NUMBER,

//From pca10040.h

#define RX_PIN_NUMBER  8
#define TX_PIN_NUMBER  6

You can change the pin configurations directly in main.c, either by passing the GPIO numbers directly, or by defining new symbols.

The SER_APP_* defines are used by the serialization solution examples.
