I've been working on a digital display project for a month, but I don't have a solution yet. We bought a display in series with the French company ACI Display that we communicate in serial port (COM4) with the simplex protocol in ASCII code I used the Java language. I manage to open the port but when I send the data on the port nothing is displayed.
import serial
def print_hi(name):
ser = serial.Serial("COM4")
print(ser.name)
ser.write(b'00')
ser.close()
if __name__ == '__main__':
print_hi('PyCharm')
Display the ticket number on my LED display in USB serial port from my Python program.
