Auxilliary LCD monitor

[jsclownfish]

I've been working on a project to make a 2nd LCD module that I could mount on the tank with no extra wires or probes. I've got it working as I want it to look with a 2nd LCD board and an Arduino. The info for the parameters and relay boxes are sending appropriately. It looks like this.....

I still have a few bugs to work out before I find a little box to mount it in and make a small Arduino board for it to connect. The 2nd LCD needs to be reset if the power turns off on the main controller or if the USB line is disconnected. I actually have to reconnect it so it has power and then remove the 5V line for a couple seconds and reconnect it. If I can't figure it out, I'll have to add a reset switch somewhere on the module. I also haven't figured out if and how to sleep the 2nd LCD and wake it if needed. I don't want to do it from the main, but I'm guessing it's not a good idea to leave it on all the time.

Comments or ideas are always welcome.

Here is the ideas I have for you.
I know you have some goodies under your hood
Why not use the RA+ as the main head unit and your standard RA as remote head unit?
You could use a USB cable and crimp a HDDB15 on the other end.
Something like this:

The sleep in the main head unit is actually not a real sleep. It's only the backlight that goes off.
The backlight is on pin#2 of Arduino board, so if you do digitalWrite(2,LOW); it should turn off the backlight of your remote unit.
Now to the connection lost handling.
Why is that you need to remove power? What is happening when connection is lost?
Are you pushing data from the main unit or pulling from the remote?
I love the work you've done so far!!! Very impressed!!
Good job!

hmmm. That could work. It might be a bit bulkier than I originally planned, but it would have the joystick to turn on the backlight without opening the cabinet and going to the main. I'd need another enclosure though.

On the power issue, I get power appropriately to a LED connected to the power line, but the LCD stays dark. If I disconnect the USB(I2C) from the controller and plug in the board with a wall wart it comes back, or if I just remove the 5V line from the USB(I2C) for a couple seconds and reconnect it comes back. Same thing happens if I use the USB from my PC.

That's pretty sweet. Are you using the web server or serial line to send the data to the slave? Is it done automatically by the slave or is the slave listening for the host to push the data?

[jsclownfish]

I'm pushing the data from the main to the slave Arduino/LCD. It is connected using the same USB line the modules use (redirecting the 4 lines to tx/rx/gnd/5V with a couple 1K resistors) for the I2C communication.

Here is the main (master) controller pde...

I think the dark screen is related to the screen saver and not because there is anything going wrong with the communication, now that I'm looking at the code.
If you go with the idea I gave you with RA+ as master and standard RA as slave, you would be able to get out of screen saver. Otherwise, we can kill the screen saver and leave the LCD constantly on.
What would you prefer?

[jsclownfish]

That could be the issue. Even without the main connected while I was working on the 2nd LCD display, I had to load the code to the Arduino with a dark screen, then disconnect the serial USB and reconnect the wall wart power after a few seconds and the LCD would come back. Is the screen saver part of the Initialization function?

-Jon

[jsclownfish]

BTW, that cable from USB to serial HDDB15 would be nice to have anyway for programming the main control. As it is now I have to keep it connected to the relay to power and make sure everything looks good on the custom main, which means I am usually sitting on the floor with my laptop next to the tank. It would be nice to just take the main unit off and connect to the PC to test code.

-Jon

[rimai]

Yeah, it is initialized on setup, but you can override it.
In the loop(), either this:

Code: Select all

ReefAngel.LCD.BacklightOn();

Or this:

Code: Select all

ReefAngel.Timer[LCD_TIMER].Start();

There is a USB power cable at the webstore that I added about a month or two ago.
http://www.reefangel.com/Products.USB-Power-Cable.ashx

[jsclownfish]

I'll try to turn off the screen saver to see if it works.
Thanks for the link. I hadn't seen it. Doesn't the communication require 4 lines? I'll probably still make a cable for a serial connection. That way I can give your idea a try and I also have trouble with the temp connectors getting them off and on without messing them up.

-Jon

[rimai]

Yes, just 4 lines.
The pinout of the HDDB15 is:
1-Relay1
2-Relay3
3-Relay5
4-Relay7
5-Relay8
6-Relay2
7-Relay4
8-Relay6
9-Not Connected
10-GND
11-Actinic PWM
12-Daylight PWM
13-SDA
14-SCL
15-+5VDC
So, all you need is make a cable and connect the SDA to D- and SCL to D+ and the power lines (VCC and GND)
Check D- and D+ pinout here:
http://pinouts.ru/Slots/USB_pinout.shtml

[jsclownfish]

Thanks Roberto. I used the same USB pinouts on the sound board I made to link as a module, but the HDDB15 pinout is helpful. Thanks. When I was asking about 4 lines, I was thinking you could upload code into the temp port connector, but I think that is just for power you still have to connect the TTL serial cable to load code right?

-Jon

[rimai]

Correct. Just power.
You still need the USB-TTL cable to upload the code.

[jsclownfish]

Roberto,

Your suggestion seems to work great. I made a cable last night and gave it a try. Curiously, the auxillary monitor doesn't seem to sleep, but the main does. I thought it was the Refresh function, but if that is removed the auxillary keeps resetting over and over again.

[Deckoz2302]

I got second screen envy....

[rimai]

That's so cool!!!

[Deckoz2302]

indeed....so roberto how much for that prototype hahaha

[rimai]

He actually has one of the RA+ boards
RA+ has an ATMega2560 chip, which has 256K of flash memory and 8K of RAM.
Plenty of memory to load all features and not have to worry about code size.
I have 2 more. PM me if you are interested

[Deckoz2302]

Oh I know that's a ra & ra+ ...I'm talking about your project on hold prototype hahaha...really though jsclownfish this is an awesome breakthrough using a 2nd arduino board(ra)

[jsclownfish]

Thanks! It doesn't really require an RA+ but it will require either a second main board or a second LCD connected to an Arduino controller.

I had an idea today. Since the joystick is there and the auxLCD is only for display purposes, I might be able to toggle between two screen formats to show more data. My hope was to use the joystick to trigger it, but a simple delay between screens would be OK. The problem is that using any delay or this code...

Code: Select all

bool bDone = false;
do
{
// wait indefinitely for a button press
delay(200);
if ( ReefAngel.Joystick.IsButtonPressed() )
{
bDone = true;
}
} while ( ! bDone );
  // Tell the controller to cleanup and return to the main screen
  //ReefAngel.DisplayedMenu = RETURN_MAIN_MODE;
// To return to the menu instead, comment out the above line and use
// this line instead
Soundsend (11,100);
ReefAngel.DisplayedMenu = ALT_SCREEN_MODE;

causes the screen to reset and the alert light to blink. At best I could change a little bit temporarily on the joystick button press function alone. Any ideas why it is resetting? I tried the clearscreen function and the refresh function as well. Same issue.

Thanks for your help,
Jon

[rimai]

It's the WDT that is kicking in.
You need this:

Code: Select all

wdt_reset();

The WDT needs to receive a reset within 1 second. If it doesn't receive the signal, it will assume that something is wrong and will reset to prevent lockup.

[jsclownfish]

yep, that did the trick. (I just removed that from the features file) The screens switch over nicely now on the press of the button. I still however can't get the data to refresh once I've entered the loop. I have a similar issue with the custom data screens. http://forum.reefangel.com/viewtopic.php?f=12&t=645 I tried to simply copy the void receiveEvent function in the loop, but couldn't get that to work.

I think you are entering into a loop that doesn't do anything:

Code: Select all

while ( ! bDone );

This will do nothing until you press the joystick.
My suggestion is instead of use the button press, use the navigation up and down or left and right to increment or decrement a global variable.
Then all you have to do is draw the screen for whatever value this variable is holding. This way you can have as many screen as you want.
Something like this:

Code: Select all

#define NumScreens 2
int ScreenID=0;

void setup()
{
}

void loop()
{
  if (ReefAngel.Joystick.IsLeft() || ReefAngel.Joystick.IsDown()) ScreenID--;
  if (ReefAngel.Joystick.IsRight() || ReefAngel.Joystick.IsUp()) ScreenID++;
  if (ScreenID<0) ScreenID=NumScreens;
  if (ScreenID>=NumScreens) ScreenID=0;
  switch (ScreenID)
  {
    case 0:
    {
      // Draw Screen 0
      break;
    }
    case 1:
    {
      // Draw Screen 1
      break;
    }
  }
}

[jsclownfish]

Thanks, I'll given that a try. The loop was something I borrowed from the custom menus so I push the button to switch screens and it stays there until I push it again to go back. The problem then is that it waits on the second screen but isn't receiving data until it exits back to the first screen once the button is pushed again. I was trying to find a way to keep receiving data while in the loop. I was thinking that switch case functions with the wire receive in each case (screen) could work.

I'll let you know how it goes.

-Jon

[jsclownfish]

Wow, that works great! I can switch data screens and the data keeps updating nicely. Now I'm dreaming about all the different screens I could display. I need to work out how to update between screens though. As long as the format is the same and writes over the last screen it works. But if it is a different format and I try to clear the screen, the loop causes the screen to look like it is flashing.

-Jon

[rimai]

Use this instead:

Code: Select all

  if (ReefAngel.Joystick.IsLeft() || ReefAngel.Joystick.IsDown())
  {
    ReefAngel.LCD.ClearScreen(DefaultBGColor);
    ScreenID--;
  }
  if (ReefAngel.Joystick.IsRight() || ReefAngel.Joystick.IsUp())
  {
    ReefAngel.LCD.ClearScreen(DefaultBGColor);
    ScreenID--;
  }

That will only clear the screen when you move the joystick .

[jsclownfish]

Outstanding!

This is so cool! I hadn't really envisioned this aspect of having an auxillary monitor that doesn't bear the weight of the other controller functions. I was messing around with it today and put this group of screens together. It easily moves from one to the next and keeps the data updating. (since I don't have all the sensors hooked up on these there are some of the 0's or Errors on the display)
Check it out....

Screens.jpg

Now I'm looking forward to really thinking about what each screen should look like and how to display the data. That should keep me busy for awhile.

Thanks for all the help!

[psyrob]

I am assuming that you can only do this with an second aurdino board and second lcd screen? Or can you use the multiple screens if you only have one controller?

[jsclownfish]

Yep, you are correct. The second LCD needs another processor to receive and display the information.

I also have trouble with the temp connectors getting them off and on without messing them up. -Jon

I do as well. I killed a temp extension cable this weekend doing this. Roberto, is there some secret to this problem? Thx in advance.
