In order, the example code...

Initializes the ESP32 over SPI using the SPI port and 3 control pins:

Tells our requests library the type of socket we're using (socket type varies by connectivity type - we'll be using the

adafruit_esp32spi_socket for this example). We'll also set the interface to an esp object. This is a little bit of a hack,

but it lets us use requests like CPython does.

Verifies an ESP32 is found, checks the firmware and MAC address

esp32_cs = DigitalInOut(board.ESP_CS)

esp32_ready = DigitalInOut(board.ESP_BUSY)

esp32_reset = DigitalInOut(board.ESP_RESET)

spi = busio.SPI(board.SCK, board.MOSI, board.MISO)

esp = adafruit_esp32spi.ESP_SPIcontrol(spi, esp32_cs, esp32_ready, esp32_reset)

requests.set_socket(socket, esp)

if esp.status == adafruit_esp32spi.WL_IDLE_STATUS:

print("ESP32 found and in idle mode")

print("Firmware vers.", esp.firmware_version)

print("MAC addr:", [hex(i) for i in esp.MAC_address])
