SPI

API

spi2 = machine.SPI(1, 500000, sck=machine.Pin(-1), miso=machine.Pin(-1), mosi=machine.Pin(-1), firstbit=machine.SPI.MSB, polarity=0, phase=0)

• Initialize the SPI interface, set the baud rate, pins, and other communication parameters.

spi2.deinit()

• Deinitialize the SPI interface, stop its operation, and release related resources.

spi2.write(buf)

• Send data from the buffer buf through the SPI interface.

spi2.write_readinto(write_buf, read_buf)

• Send data from write_buf through the SPI interface and simultaneously receive data into read_buf.

str(spi2.read(0))

• Read the specified number of bytes from the SPI interface and convert the result to a string.

spi2.readinto(buf)

• Read data from the SPI interface and store it into the buffer buf.
