[!NOTE] I had sent this example to Anton. He created a similar example here.

Minimal Example

Minimalistic example for Lego Spike with Pybricks + LMS-ESP32 board using the onboard neopixel.

Depending on the value of the LEGO force sensor, the led will vary from green to red.

Prerequisites

• Lego Spike with Pybricks firmware
• LMS-ESP32v2 board from [https://www.antonsmindstorms.com/] with MicroPython firmware

Steps

LMS-ESP32

Upload this snippet with Thonny as main.py:

from neopixel import NeoPixel
from pupremote import PUPRemoteSensor

def led(v):
    print(v)
    np[0]=(v, 255-v, 0) # green to red
    np.write()
    
np = NeoPixel(Pin(25), 1) # onboard neopixel
np[0] = (0, 0, 255) # blue
np.write()
rs = PUPRemoteSensor(power=True)
rs.add_command('led', '', 'B')
rs.process()
while True:
    rs.process()

Lego Spike

Insert this snippet into Pybricks Code IDE as main.py:

from pybricks.pupdevices import ForceSensor
from pybricks.parameters import Port
from pybricks.tools import wait
from pupremote_hub import PUPRemoteHub # copy from https://github.com/antonvh/PUPRemote/blob/main/src/pupremote_hub.py

fs = ForceSensor(Port.A)
rh = PUPRemoteHub(Port.B)
rh.add_command('led', '', 'B')
while True:
    v = min(255, int(fs.force()*25.0)) # map from 0-10.xx to 0-255
    print(v)
    rh.call('led', v)
    wait(100)
