Smeigtuko apibrėžimas
About SPI, I2C, UART, PWM, QPSI, I2S, PDM, QDEC: Each IO pin is preconfigured with IO_MUX functionality, which means you can use any GPIO as peripheral pins. You just need to define these pins in your code.
However, it’s important to note that once a pin is used, it may affect other functions associated with that pin. For information, please refer to the Schemaic diagram.
