关闭MU系列时,微控制器串行停止工作

我正在尝试控制一些Neopixel灯,并且由于Raspberry Pi只能在任何给定时间控制一个灯,所以我决定我只能得到一个微控制器来执行此操作,特别是Adafruit Itsybitsy M4 Express,只需通过USB连接两者以控制它们。我可以使用四义性的词,将数据发送给微控制器。但是,在RPI脚本发送数据8次之后,它停止工作,我必须重新加载脚本。添加剂,通过停止工作,我的意思是脚本被卡住了发送数据而永无止境。奇怪的部分是,如果我在脚本开始运行后打开MU序列号,我可以:查看发送的数据,B:它永远不会停止。它已经超越了8期并继续前进。 RPI代码:

import serial
import time
from random import randint
a = time.time() #Unimportant, was looking to see how quickly Serial could be re-defined
try:
    ser = serial.Serial(port='/dev/ttyACM1', baudrate=115200, write_timeout=0.05)
except:
    ser = serial.Serial(port='/dev/ttyACM0', baudrate=115200, write_timeout=0.05) 
print(time.time() - a)
EnterKey = "\x1A\r\n"
e = 0
while True:
    e+=1 
    d = []
    for number in range(0, 30):
        d.append([randint(0, 255), randint(0, 255), randint(0, 255)])
    d = ((str(d)) + EnterKey).encode()
    ser.write(d)
    time.sleep(1)
    print(e)

微控制器代码:

import board
import supervisor
import neopixel
import time
a = neopixel.NeoPixel(board.D5, 30, auto_write=False)
supervisor.diable_autoreload()
while True:
    b = input("automated")
    RST = []
    c = ""
    R3T = []
    started = False
    for value in b:
        if started == True:
            if value == '[':
                started2 = True
                ending = False
            elif value == ']':
                if ending == True:
                    started=False
                else:
                    RST.append(int(c))
                    c = ""
                    ending = True
                    started2 = False
                    R3T.append(RST)
                    RST = []
            elif started2 == True:
                if value.isdigit():
                    c += value
                elif value == ",":
                    RST.append(int(c))
                    c = ""
        elif value == '[':
            started = True
    for value in range(0, 30):
        a[value] = R3T[value]
    a.show()
    print(a)

我尝试懒惰,只是在写入超时后重新定义串行对象,但这不起作用。 (ERRNO 16]设备或资源忙)。然后,我四处寻找Raspberry Pi设置,看看是否有任何妨碍我的路,但什么也没发现。我最终放弃了,来到这里。如果您有任何想法,请告诉我!

I am trying to control some NeoPixel lights, and because the Raspberry Pi can only control one light at any given time, I decided I would just get a microcontroller to do it, specifically the Adafruit ItsyBitsy M4 Express, and just send serial data through the USB connecting the two to control them. I got that working, using PySerial to send data to the microcontroller. However, after the RPi script sends data 8 times, it stops working and I have to reload the script. Additonally, by stop working, I mean that the script gets stuck sending data and never ends. The strange part is that if I open the MU serial after my script has started running, I can A: see the data being sent in, and B: it never stops. It goes past the 8 issue and keeps going.
RPi Code:

import serial
import time
from random import randint
a = time.time() #Unimportant, was looking to see how quickly Serial could be re-defined
try:
    ser = serial.Serial(port='/dev/ttyACM1', baudrate=115200, write_timeout=0.05)
except:
    ser = serial.Serial(port='/dev/ttyACM0', baudrate=115200, write_timeout=0.05) 
print(time.time() - a)
EnterKey = "\x1A\r\n"
e = 0
while True:
    e+=1 
    d = []
    for number in range(0, 30):
        d.append([randint(0, 255), randint(0, 255), randint(0, 255)])
    d = ((str(d)) + EnterKey).encode()
    ser.write(d)
    time.sleep(1)
    print(e)

Microcontroller code:

import board
import supervisor
import neopixel
import time
a = neopixel.NeoPixel(board.D5, 30, auto_write=False)
supervisor.diable_autoreload()
while True:
    b = input("automated")
    RST = []
    c = ""
    R3T = []
    started = False
    for value in b:
        if started == True:
            if value == '[':
                started2 = True
                ending = False
            elif value == ']':
                if ending == True:
                    started=False
                else:
                    RST.append(int(c))
                    c = ""
                    ending = True
                    started2 = False
                    R3T.append(RST)
                    RST = []
            elif started2 == True:
                if value.isdigit():
                    c += value
                elif value == ",":
                    RST.append(int(c))
                    c = ""
        elif value == '[':
            started = True
    for value in range(0, 30):
        a[value] = R3T[value]
    a.show()
    print(a)

I tried being lazy and just re-defining the serial object after a write timeout, but that does not work. (Errno 16] Device or resource busy). I then went around looking for Raspberry Pi settings seeing if anything was getting in my way, but found nothing. I ultimately gave up and came here. If you have any ideas, please tell me!
