Re: about ATWINC3400 module的GPIO pin的使用

1. We don’t recommend using the GPIOs on WINC3400 because it is slow and could messed up some WINC3400 functions. We recommend only using nm_bsp to control GPIO on MCU.
2. It is possible to program WINC3400 firmware from I2C or debug UART. However, the easiest way to update firmware with Microchip development board is to burn it from a SAMD21 or SAMG55 MCU.

Let me know if you need further help.
