Hola, no consigo ejecutar la variable
date = subprocess.getstatusoutput('date')
en mi lcd. Intento ejecutar el comando date y guardarlo en la variable date, pero cuando la pongo en este script de prueba
de esta forma LCD.lcd_string((date),LCD.LINE_1) me da un error, pero creo que es causa del modulo LCDLIB16x2 as LCD ya que cuando ejecuto el script con la variable me da un error en el : File "/home/pi/Desktop/LCDLIB16x2.py", line 103, in lcd_string
message = message.ljust(LCD_WIDTH,)
AttributeError: 'tuple' object has no attribute 'ljust'
Este script es el que intento ejecutar
