I want to disable the interrupts completely for the UART stack I have added. I dont want any ISRs to come into the code. I just want to use it in polling mode fully. can you help me with this to remove or disable the following 4 interrupts and their ISRs from the UART configuration?
Hi,
Thank you for reaching out.
In Renesas FSP, UART communication is designed to be non-blocking, and the interrupts shown in your configuration are an integral part of the FSP UART stack. Unfortunately, there is no built-in polling mode available in the FSP UART driver.
If you wish to use UART in a purely polling-based approach, you will need to implement your own application code to manually check the status flags and read/write data accordingly. This involves directly interacting with the hardware registers instead of relying on the provided driver.
Please let us know if you need any guidance on implementing this approach. We’d be happy to assist you further.
Kind regards,
PS
Yes. Help me in this to enable polling mode for the board for establsihing the UART communication while embOS is integrated.
As I mentioned before, Polling mode is not supported in the FSP UART driver. The FSP UART implementation is designed to be non-blocking and relies on interrupts or DMA for efficient communication. Since there is no built-in polling mechanism, the UART driver cannot operate purely in polling mode.
Thank you!
