C++ (Cpp) uart_poll_in Examples

Example #1

File: UARTClass.cpp Project: 00alis/corelibs-arduino101

void UARTClass::IrqHandler( void )
{
  uint8_t uc_data;
  int ret;
  ret = uart_poll_in(CONFIG_UART_CONSOLE_INDEX, &uc_data);
  
  while ( ret != -1 ) {
    _rx_buffer->store_char(uc_data);
    ret = uart_poll_in(CONFIG_UART_CONSOLE_INDEX, &uc_data);
  }

    }
    else
    {
      // Mask off transmit interrupt so we don't get it anymore
      uart_irq_tx_disable(CONFIG_UART_CONSOLE_INDEX);
    }
  }
}

Example #2

File: uart_console.c Project: hudkmr/zephyr

static int console_in(void)
{
	unsigned char c;

	if (uart_poll_in(uart_console_dev, &c) < 0)
		return EOF;
	else
		return (int)c;
}

Example #3

File: main.c Project: 32bitmicro/zephyr

static void test_by_polling(struct device *dev)
{
	unsigned char data;

	write_string(dev, banner1, strlen(banner1));

	/* Poll in the character */
	while (uart_poll_in(dev, &data) == -1)
		;

	write_string(dev, banner2, strlen(banner2));
	write_string(dev, &data, 1);
	write_string(dev, "\n", 1);
}

Example #4
