hello,

how can i displaye time a 16 x 2 LCD or how to display the value of "value" to the LCD ( i get an error) . Im using a raspberry pi and my code is in python

import time

import sys

import Adafruit_CharLCD as LCD

import Adafruit_GPIO.MCP230xx as MCP

from datetime import datetime

# Define MCP pins connected to the LCD.

lcd_rs = 0

lcd_en = 1

lcd_d4 = 2

lcd_d5 = 3

lcd_d6 = 4

lcd_d7 = 5

lcd_red = 6

lcd_green = 7

lcd_blue = 8

# Define LCD column and row size for 16x2 LCD.

lcd_columns = 16

lcd_rows = 2

# Initialize MCP23017 device using its default 0x20 I2C address.

gpio = MCP.MCP23017()

# Initialize the LCD using the pins

lcd = LCD.Adafruit_RGBCharLCD(lcd_rs, lcd_en, lcd_d4, lcd_d5, lcd_d6, lcd_d7,

lcd_columns, lcd_rows, lcd_red, lcd_green, lcd_blue,

gpio=gpio)

# Print a two line message

lcd.message('Hello!')

# Wait 5 seconds

time.sleep(5.0)

# time and ip address

cmd = "ip addr show eth0 | grep inet | awk '{print $2}' | cut -d/ -f1"

lcd.begin(16,1)

def run_cmd(cmd):

p = Popen(cmd, shell=True, stdout=PIPE)

output = p.communicate()[0]

return output

while 1:

lcd.clear()

ipaddr = run_cmd(cmd)

lcd.message(datetime.now().strftime('%b %d %H:%M:%S '))

lcd.message('IP %s' % ( ipaddr ) )

sleep(2)

# Show some basic colors.

value = float(input("Enter Value : "))

if value < 45:

lcd.set_color(0.0, 0.0, 1.0)

lcd.clear()

lcd.message('Below optimal temperature')

print('COLD'.format(value))

time.sleep(3.0)

if value > 70:

lcd.set_color(1.0, 0.0, 0.0)

lcd.clear()

lcd.message('RED')

time.sleep(3.0)

else:

lcd.set_color(0.0, 1.0, 0.0)

lcd.clear()

lcd.message('GREEN')

time.sleep(3.0)
