Sending and Receiving Data via UART using interrupts in NIOS

Question

Hello,I am trying to send and receive data from UART using interrupts in NIOS soft-core processor. I have registered the "Interrupt Handler function", and registered it using "alt_irq_register()" function. But my program gets stuck in an infinite loop while trying to close the UART File handler. Can anybody please  help me resolve the issueThanks and RegardsPrince

Hi,

This is been done so many times before. I am sharing with you now a design example that will teach you how to create a UART and use the interrupts with it.

If you need more help please let me know.

Regards,
