tkl_pinmux | PINMUX Driver

Brief Description​

Pinmux is used for mapping and multiplexing peripheral pins.

API Description​

tkl_io_pinmux_config​

OPERATE_RET tkl_io_pinmux_config(TUYA_PIN_NAME_E pin, TUYA_PIN_FUNC_E pin_func);
  • Function Description:
    • Configure the function of an IO pin.
  • Parameters:
    • pin: Pin number.
    • pin_func: Pin function.
  • Return Value:
    • Error code, refer to the file tuya_error_code.h.

tkl_multi_io_pinmux_config​

OPERATE_RET tkl_multi_io_pinmux_config(TUYA_MUL_PIN_CFG_T *cfg, uint16_t num);

  • Function Description:

    • Multiplexed configuration of multiple IO pin functions using pinmux.

  • Parameters:

    • cfg: Pointer to the configuration structure.

      TUYA_MUL_PIN_CFG_T

      typedef  struct {
          TUYA_PIN_NAME_E pin;           // Pin number
          TUYA_PIN_FUNC_E pin_func;       // Pin function
      } TUYA_MUL_PIN_CFG_T;

    • num: Number of configurations.

  • Return Value:

    • Error code, refer to the file tuya_error_code.h.

tkl_io_pin_to_func​

int32_t tkl_io_pin_to_func(uint32_t pin, TUYA_PIN_TYPE_E pin_type);
  • Function Description:
    • Query the port and channel numbers from an IO pin.
  • Parameters:
    • pin: Pin number.
    • pin_type: Query type.
  • Return Value:
    • The port and channel numbers corresponding to the pin.
    • Bits 0-7 correspond to the channel, and bits 8-15 correspond to the port.
    • < 0 indicates not found.

Examples​

tkl_io_pinmux_config(TUYA_IO_PIN_0, TUYA_IIC0_SCL);
tkl_io_pinmux_config(TUYA_IO_PIN_1, TUYA_IIC0_SDA);
TUYA_MUL_PIN_CFG_T cfg[2];
cfg[0].pin = TUYA_IO_PIN_0;
cfg[0].pin_func = TUYA_IIC0_SCL;

cfg[1].pin = TUYA_IO_PIN_1;
cfg[1].pin_func = TUYA_IIC0_SDA;

tkl_multi_io_pinmux_config(cfg, 2);
