Hello How do I get my required library for my pico, hopefully using thonny to get the library ?I have two pico's two nrf24l01's and two push switches. I am trying to use this example and download the drivers ( I use thonny ), when I click on the link I to get the library, I get error message: The 'micropython/micropython' repository doesn't contain the 'drivers/nrf24l01' path in 'master'. Here is my system: If I use Thonny [ tools, Mange packages ] and try to install anything with nrf24 in it I get error message: this does not look like a Micropython/circuitpython package, are you sure you want to install it ? ### Here is the code: from machine import Pin, SPI import struct from nrf24l01 import NRF24L01 led = Pin(25, Pin.OUT) # LED btn = Pin(28, Pin.IN, Pin.PULL_DOWN) # button press csn = Pin(15, mode=Pin.OUT, value=1) # chip select not ce = Pin(14, mode=Pin.OUT, value=0) # chip enable Addresses are in little-endian format. They correspond to big-endian 0xf0f0f0f0e1, 0xf0f0f0f0d2 - swap these on the other Pico!pipes = (b"\xe1\xf0\xf0\xf0\xf0", b"\xd2\xf0\xf0\xf0\xf0") def setup(): nrf = NRF24L01(SPI(0), csn, ce, payload_size=4) nrf.open_tx_pipe(pipes[0]) nrf.open_rx_pipe(1, pipes[1]) nrf.start_listening() led.value(0) return nrfdef demo(nrf): state = 0 while True: if state != btn.value(): state = btn.value() led.value(state) print("tx", state) nrf.stop_listening() try: nrf.send(struct.pack("i", state)) except OSError: print('message lost') nrf.start_listening() if nrf.any(): buf = nrf.recv() got = struct.unpack("i", buf)[0] print("rx", got) led.value(got)def auto_ack(nrf): nrf.reg_write(0x01, 0b11111000) # enable auto-ack on all pipes nrf = setup() auto_ack(nrf) demo(nrf) |
