esp32c3 > gpio > mapping spi2 pins

[BugSimpson]

Hello community, I'm trying in vain to get the pins from the SPI2 interface to the pins specified in the source code.

What have I forgotten?

Code: Untitled.c Select all

  gpio_pin_map_to_peripheral(6, 64);

  gpio_pin_map_to_peripheral(12, 63);

  gpio_pin_map_to_peripheral(13, 65);

  gpio_pin_map_to_peripheral(16, 68);



  gpio_set_io_mux(6, 2, 0); // gpio2 / miso (fspiq)   

  gpio_set_io_mux(12, 2, 0); // gpio6 / clock (fspiclk)

  gpio_set_io_mux(13, 2, 0); // gpio7 / mosi (fspid)

  gpio_set_io_mux(16, 2, 0); // gpio10 / chip select (fspics0)



void gpio_pin_map_to_peripheral( uint8_t _pin, uint8_t _periphSignal )

{

    REG_WRITE( GPIO_FUNCx_OUT_SEL_CNFG_REG( _pin ), _periphSignal );

}



void gpio_set_io_mux(uint8_t _pin, uint8_t _func, uint8_t _inv )

{

  REG_SET_BIT( IO_MUX_GPIOn_REG(_pin), (_func<12) | (_inv<<8));  

}

Code: Select all

(_func<12)

Missing one "<"?

And MISO needs to be input.

ohh sh** yes! thank you. its work!
