Dear Members,
I saw this example,
I can not find this example on SDK 17,
How can I use UARTE0 and UARTE1 on separate port ? one is for debugging via USB and the other one for communicating with GPS UART ?
Any suggestions ?
Thanks

Hi,
The Serial port library has been deprecated and has been replaced with the libUARTE module. We have a libUARTE example in the SDK that only uses one instance but clearly shows how to define an instance and initialize it. It should be possible to repeat this for a second UARTE instance. If you want to use two UARTE instances then you have to enable both instances in the config file and resources that the module is dependent on ( Timer and PPI) . Next you have to define an instance of the module and initialize it in the project.

Jared
How can I " ... enable both instances in the config file and resources that the module is dependent on " ?
?
like this :
nrf_libuarte_async_config_t nrf_libuarte_async_config1 = {
.tx_pin = SER_APP_TX_PIN,
.rx_pin = SER_APP_RX_PIN,
.baudrate = NRF_UARTE_BAUDRATE_115200,
.parity = NRF_UARTE_PARITY_EXCLUDED,
.hwfc = NRF_UARTE_HWFC_DISABLED,
.timeout_us = 100,
.int_prio = APP_IRQ_PRIORITY_LOW
};
then on sdk_config.h ?
Thanks
then
err_code = nrf_libuarte_async_init(&libuarte, &nrf_libuarte_async_config1, uart_event_handler1, (void *)&libuarte);
void uart_event_handler1(void * context, nrf_libuarte_async_evt_t * p_evt)
{
}
?
Please correct me, it's not responding when I run libuarte1 :
NRF_LIBUARTE_ASYNC_DEFINE(libuarte, 0, 0, 0, NRF_LIBUARTE_PERIPHERAL_NOT_USED, 255, 3); NRF_LIBUARTE_ASYNC_DEFINE(libuarte1, 1, 0, 0, NRF_LIBUARTE_PERIPHERAL_NOT_USED, 255, 3); nrf_libuarte_async_config_t nrf_libuarte_async_config = { .tx_pin = TX_PIN_NUMBER, .rx_pin = RX_PIN_NUMBER, .baudrate = NRF_UARTE_BAUDRATE_115200, .parity = NRF_UARTE_PARITY_EXCLUDED, .hwfc = NRF_UARTE_HWFC_DISABLED, .timeout_us = 100, .int_prio = APP_IRQ_PRIORITY_LOW }; nrf_libuarte_async_config_t nrf_libuarte_async_config1 = { .tx_pin = SER_APP_TX_PIN, .rx_pin = SER_APP_RX_PIN, .baudrate = NRF_UARTE_BAUDRATE_9600, .parity = NRF_UARTE_PARITY_EXCLUDED, .hwfc = NRF_UARTE_HWFC_DISABLED, .timeout_us = 100, .int_prio = APP_IRQ_PRIORITY_LOW }; err_code = nrf_libuarte_async_init(&libuarte, &nrf_libuarte_async_config, uart_event_handler, (void *)&libuarte); err_code = nrf_libuarte_async_init(&libuarte1, &nrf_libuarte_async_config1, uart_event_handler1, (void *)&libuarte1);
Hi,
Have you enabled the second instance of the UARTE in the config file?
RixtronixLAB said:it's not responding when I run libuarte1
Be more specific. What exactly happens? What does the init function return? Use the debugger and see if the application asserts somewhere.

How can I implement this app with libuarte ?
\nRF5_SDK_15.2.0_9412b96\examples\peripheral\serial_uartes
thanks
