pySerial在Arduino和SRAM芯片之间将数据发送到Arduino和SPI之间的冲突

Question

我正在通过pySerial将阵列发送到Arduino Nano的过程中，一旦接收到，Nano就会使用SPI直接发送到SRAM芯片。但是，当执行与SPI相关的代码（例如设置用于发送单个字节的传输模式）时，将阻止从Python传输数据。

我知道问题并非出自同时使用两个引脚，因为它们使用不同的引脚，因此我认为函数定义存在问题。我觉得不得不说我在python和arduino方面的专业知识很少。对于长代码的道歉以及对此的任何帮助，将不胜感激！

# Python code
import serial      
import time                                    #To use delay functions   
ArduinoNano = serial.Serial('com6',9600)       #Create Serial port object called ArduinoNano
x = ArduinoNano.readline()                     #Read the serial data and print it
print(x)

gImage_1 = bytes([
0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,
0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XC0,
0X00,0X00,0X00,0X00,0X00,0X00]);

t = 0
for t in gImage_1:
    ArduinoNano.write(bytes([t]))
    y = ArduinoNano.readline()
    print(y)
