It directly removes everything from display. (10:00)

First it will look if there is a button pressed. If there is no button pressed it will be 00 and then it will be just refresh the last one.
When pressed it will directly remove the previous text. Because at the beginning it wil if not 00 is pressed with !=. So, it will directly remove the previous text when pressed.


Then it will start the while loop. ( while true; do)

Push menu

1. Temperature  (From blog 05)
2. Time with load averages (From blog 04)
3. CPU + GPU (From blog 08)
4. Temperature at weather station (From blog 09) 
5. Wind a weather station (From blog 09) 
6. Defining Temperature ( not visible on display! ) (From blog 05)

I used previous codes, but I copied them in a new version. Example:

cp timer > time_load 

You have to make the script get to the basic, so that it only prints. So things like this has to be removed:

while true
done
echo 
10:00/11:00

Note! You shouldn't delete 11:20, because the script from pushmenu isn't made to to also remove the second line. It only cleans first row with 11:00.

Example from the 'Time with load averages':

#!/bin/bash

DISPL="bw_tool -I -D /dev/i2c-1 -a 94"

       load=`cut -d' ' -f-3 /proc/loadavg`
       $DISPL -t `date +%H:%M:%S`
       $DISPL -W 11:20:b
       $DISPL -t $load
#!/bin/bash 

#Print=showtemp2
#Print=time_load
#Print=DIAMoscow2
#Print=cgpu2
#Print=DIAMWind
Print=ui
bw_tool -I -D /dev/i2c-1 -a 94 -w 10:00 

while true; do
  Button=`bw_tool -I -D /dev/i2c-1 -a 94 -R 30:b`
  
  if [ $Button  != "00" ]; then 
    bw_tool -I -D /dev/i2c-1 -a 94 -w 10:00
  fi

  if [ $Button  = "20" ]; then 
    Print=showtemp2
  fi  

  if [ $Button  = "10" ]; then 
    Print=time_load
  fi 

  if [ $Button  = "08" ]; then 
    Print=cgpu2
  fi

  if [ $Button  = "04" ]; then 
    Print=DIAMoscow
  fi

  if [ $Button  = "02" ]; then 
    Print=DIAMWind
  fi

  if [ $Button  = "01" ]; then 
    Print=ui
  fi

  bw_tool -I -D /dev/i2c-1 -a 94 -w 11:00
  ./$Print

  sleep 1
done

All the 6 buttons reference to 6 scripts:

1. Temperature
2. Time 
3. CPU +GPU
4. Temperature at weather station
5. Wind at weather station 
6. ui

The first list can delete the and only turn on 1 of them. If you remove it, it wouldn't be a problem on the display but a error. I found out this later, but left the others there because I thought maybe some people would like to start with an other one. It directly removes everything from display. (10:00)

First it will look if there is a button pressed. If there is no button pressed it will be 00 and then it will be just refresh the last one. When pressed it will directly remove the previous text. Because at the beginning it wil if not 00 is pressed with !=. So, it will directly remove the previous text when pressed.

Then it will start the while loop. ( while true; do) When started it will first look if it detects which button is pressed.

After that I made 6 if statements to check of that button is pressed. ( to detect which button gives which number:

bw_tool -I -D /dev/i2c-1 -a 94 -R 30:b
01

) Press the number you want to know and press the button.

At the end it says it has to place on the line 11:00 and with ./$print he that finally print the every second the one information from the button pressed.

Thanks to the sleep you now have to wait a second to recognize the different button you pressed. Because it has to go trough that list again in that 1 sec.


I hope this can also be useful for your own use.
