Hello,
Please use the HID class to implement keypad application. Kindly, refer to the hid_examples firmware that comes with the FX3 SDK as a reference.

Hello,
So the IO(53:56) should be configured for a keypad? by connecting it to the spi gpio pins?
The GpioClock & GpioConfig should be edited in the CyFxHidApplnGpioInit to intialize the spi gpio?
Thanks,

Hello,
Any GPIO pin of FX3 can be used as keypad button. The example shows only a reference implementation.

Hello,
- Please let me know if your application requires to send debug messages or the keypad inputs.
- Are you using the SPI pins in its normal SPI mode or as GPIO pins. If you would want to use the SPI pins as GPIOs, please use the CyU3PDeviceGpioOverride() API.
- Kindly, attach the firmware project if possible.
Best regards,
