Hello,
I use interrupt driven UART ("ittyb:") in my project and wanted to send and receive strings over the UART.
I am able to receive the string, but only one byte is transmitting from the UART, Here is my sample uart ISR
void serial_isr(void *user_isr_ptr)
{
UART_MemMapPtr sci_ptr = _bsp_get_serial_base_address (1); //DES get base address for UART5
uData = sci_ptr->S1; //DES read status register. Part of two step process to clear the interrupt flag.
uData = sci_ptr->D; //DES get the character
//printf("%c", uData);
switch(uData)
{
// Data processing...
}
}
In main task:
void SerialZero_Task(uint32_t initial_data)
{
serial_ptr = fopen (SERIAL_CHANNEL_ZERO, BSP_DEFAULT_IO_OPEN_MODE);
if( serial_ptr == NULL )
{
printf("Error: Unable to open IO channel\n");
_task_block();
}
param = TRUE;
result = ioctl( serial_ptr, IO_IOCTL_SERIAL_SET_FLAGS , ¶m );
if( MQX_OK != result )
{
_task_block();
}
result = ioctl(serial_ptr, IO_IOCTL_SERIAL_SET_BAUD, &baudrate);
if (MQX_OK != result)
{
_task_block();
}
_nvic_int_init(INT_UART1_RX_TX, 2, TRUE);
_nvic_int_enable(INT_UART1_RX_TX);
_int_install_isr(INT_UART1_RX_TX, serial_isr, serial_ptr);
while()
{ }
}
