CircuitPython Installation of ESP32SPI
Library
You'll need to install the
Adafruit CircuitPython ESP32SPI
librar
y on your CircuitPython board.
First make sure you are running the
latest version of Adafruit CircuitPython
(https://
adafru.it/Amd)
for your board.
Next you'll need to install the necessary libraries to use the hardware--carefully follow
the steps to find and install these libraries from
Adafruit's CircuitPython library bundle
(https://adafru.it/uap)
. Our CircuitPython starter guide has
(https://adafru.it/ABU)
.
You can manually install the necessary libraries from the bundle:
adafruit_esp32spi
adafruit_requests.mpy
adafruit_bus_device
Before continuing make sure your board's lib folder or root filesystem has the adafrui
t_esp32spi, adafruit_requests.mpy, and adafruit_bus_device files and folders copied
over.
Next
make sure you are set up to connect to the serial console

CircuitPython Usage
Copy the following code to your code.py file on your microcontroller:
import
board
import
busio
from
digitalio
import
DigitalInOut
from
adafruit_esp32spi
import
adafruit_esp32spi
(
"ESP32 SPI hardware test"
)
esp32_cs
=
DigitalInOut(board.D13)
esp32_reset
=
DigitalInOut(board.D12)
esp32_ready
=
DigitalInOut(board.D11)
spi
=
busio.SPI(board.SCK, board.MOSI, board.MISO)
esp
=
adafruit_esp32spi.ESP_SPIcontrol(spi, esp32_cs, esp32_ready, esp32_reset)
