I am using TWR K60N512 with mqx 4.0 .I need to create an ISR function for uart3 interrupt that trigger whenever a character is received .I tried to create an ISR function, but it never gets triggered.
These are my initialization steps
#define RS232CHANNEL "ittyd:"
rs232_dev = fopen( RS232CHANNEL, BSP_DEFAULT_IO_OPEN_MODE );
_nvic_int_init(INT_UART3_RX_TX, 2, TRUE);
_int_install_isr(INT_UART3_RX_TX, uart3_rx_tx_isr, rs232_dev);
I have enabled the ITTYD in userconfig.h
The following is the ISR function that i created.
if (fstatus( rs232_dev ))
ubUDR = fgetc( rs232_dev );
Can anybody provide me a sample code for the same or help me to create an ISR that trigger whenever a character is received?.
