UART Init without FIFO:

[Shibi]

I am using 3 uarts for my applications using nrf52xx, i want uart without fifo,i configure 3 uarts independently and use the

#define APP_UART_INIT(
 	P_COMM_PARAMS,
 	EVT_HANDLER,
 	IRQ_PRIO,
 	ERR_CODE 
)

for initialising my uarts.but this functions return a error as NRF_ERROR_INVALID_PARAM,

if (p_buffers == NULL)
{
     	return NRF_ERROR_INVALID_PARAM;
}

if any body have solution for multiple uart init, please help?

Hi,

The p_buffers condition is in app_uart_fifo.c, not app_uart.c. You seem to be using the wrong source file if you don't want to use FIFO

thanks for reply, if i am using app_uart.c source file, what will be in uart event handler? Regards shibil​

You don't have anything to change APP_UART_INIT is meant to be used with app_uart.c APP_UART_FIFO_INIT is meant to be used with app_uart_fifo.c
