    Hi Nidhi,

    Thanks for posting your question online.

    In setup to perform floating point operations with library calls, you should add-mfloat-abi = soft. Please refer to-mfloat-abi = name on https//gcc.gnu.org/onlinedocs/gcc-4.4.7/gcc/ARM-Options.html

    In setup to apply functions printf and scanf functions, you should add these 2 linker options

    Hope it helps

    Regards

Hi,

Configured IRQ Control Register (IRQCRi) rising and falling edge discovery (IRQMD{10}).
When the interrupt of the edge discovery is raised, where to find out which edge falling or rising is detected, I need to know what’s the pin position of the GPIO input pin when an edge is detected.

The used CPU is RA2E1.

    Thanks for posting your question!

    You could check your IRQ- pin’s level when entering your interrupt message function in order to check if a rising or falling edge is detected. In case your pin’s level was initially low and when entering your message function it became high then a rising edge was detected. If your pin was initially high and also became low then a falling edge was detected. You could read your pin level by accessing the register shown in the picture below.

    For example, if your IRQ pin is P110, you could check its level in the interrupt message function like this:
    R_PORT1->PIDR_b. PIDR10 and check if it’s 1 (HIGH) or 0 (LOW).

    Another way is by using the already given API
    1.fsp_err_tR_IOPORT_PinRead(ioport_ctrl_t * constp_ctrl,bsp_io_port_pin_t pin,bsp_io_level_t *p_pin_value);

    Kind Regards,
    Alex
