hi scott.

first of all thanks for the tips.

i will be happy to get some nios ii ide code example for same scenario.

i want to understand how to use uart interrupts and to apply it in my application.

regards .

Altera provide a driver for the UART, you don&#39;t need to worry about handling the interrupts from the UART. I suggest you either look at the hello world example or read the Nios II Software Developers Handbook.

I have the same question of how to receive and transmit data using UART interrupt .I have read the Nios II Software Developers Handbook and driver for the UART, but I don&#39;t know how to use the API function of HAL,

for example:

1,how to declare the "fd" parameter of alt_avalon_uart_read (alt_fd* fd, char* ptr, int len)?

2,Can I use the alt_avalon_uart_read (alt_fd* fd, char* ptr, int len) directly or use it throuth some other system function sush as read()?

can you give me some example about it ?
