// For ESP32, the remaining five pins are at least somewhat configurable.
|
|
// eth_address is in range [0..31], indicates which PHY (MAC?) address should be allocated to the interface
|
|
// eth_power is an output GPIO pin used to enable/disable the ethernet port (and/or external oscillator)
|
|
// eth_mdc is an output GPIO pin used to provide the clock for the management data
|
|
// eth_mdio is an input/output GPIO pin used to transfer management data
|
|
// eth_type is the physical ethernet module's type (ETH_PHY_LAN8720, ETH_PHY_TLK110)
|
|
// eth_clk_mode defines the GPIO pin and GPIO mode for the clock signal
|
|
// However, there are really only four configurable options on ESP32:
|
|
// ETH_CLOCK_GPIO0_IN == External oscillator, clock input via GPIO0
|
|
// ETH_CLOCK_GPIO0_OUT == ESP32 provides 50MHz clock output via GPIO0
|
|
// ETH_CLOCK_GPIO16_OUT == ESP32 provides 50MHz clock output via GPIO16
|
|
// ETH_CLOCK_GPIO17_OUT == ESP32 provides 50MHz clock output via GPIO17
