Hello...
Does anyone have any good luck using the RFM69 with LCD's? If so, which ones?
I find the standard 16x2 with the "backback" does not compile with the radio library included
The Nokia as well as a few others stay blank.
Anyone know of issues, or have any they had good luck with? Any tricks to make them work, especially the infamous Nokia?
I'd be happy to mention the errors, but I figured someone else had to run across this. I'd like a display on a couple of my nodes, but am having bad luck, and before I spent the time to dig deeper, I wanted some opinions.
Thanks!

Hi Computourist... Yes, I do already have a copy of it, and honestly I was going to look at it, but it really wasn't the LCD I desired - now you probably think I'm picky!  I see now - you hooked yours up in parallel...I was avoiding that because of the use of all the digital pins. (I have a node I wanted to use it on, to recover heat from my dryer vent. This node controls a servo, has a transistor for water leak and DHT11 to sense too much humidity and close it) With all of this, I cant afford to use that many pins, so I used that same display with the backpack. When it didnt compile, I decided to move on to the 5110 display, as it was just as cheap and had more lines. No luck with it either. Also, I have a couple of the larger color models also I intended to use with the projects - I envisioned a mini color control panel to send MQTT commands just like a node... Nevertheless, I'm beginning to wonder if it's not just voltage problems with the others...but the 44780 with the serial "backpack" gives an error compiling. I'll post it and see what you think. But to your point, I did look at your code, and I didnt follow it very far because of the digital pin consumption - It wasnt going to work for what I was trying to do. Thanks, and let me know your thoughts... |

Jim, something like this is a node I want to do also. I have a mega clone and 3.5 tft with the Adafruit board "when they get back in stock" I am going to start on it.
Mega $10 for all of the pins
tft $10
Adafruit board $10
Not to bad for a small touch screen interface.

Hi Greg... I agree on the Mega...its a possibility, but the size of it makes it stick out past the tft, so you'll have a border. I see there is now a mini mega for about $15...But now pricewise, your getting close to $30, and for that, why not just do this: www.homeautomationforgeeks.com/dashboard.shtmlwhich I did. So maybe I'll keep your Mega Idea for the node... I still need to dig into the problems with the displays though, I havent seen one yet that has worked simultaneously with the radio. They cant all have a library or memory conflict- which is why I was wondering if anyone else tried and thought maybe it was a power problem. Right now, as my system is new, and I'm trying to catch up with you all  , I'm taking the plunge to OpenHAB2 anyway. I dont have much together anyway, so I figured I'd start fresh. Right now, I'm concentrating on getting the carport presence node to turn on a GE Lijnk light bulb through a rooted WinkHub. And by the way, the winkhub section of this proboards looks pretty dormant...I have a couple issues, was wondering if anyone else was working with a rooted one as well... |

why not just do this: www.homeautomationforgeeks.com/dashboard.shtmlwhich I did. I did this also, but it stopped updating after some random time 10hrs to 2days. I do not know if it is the server or client also the look did not pass WAF. Later I might go to the dashing dashboard So maybe I'll keep your Mega Idea for the node... I still need to dig into the problems with the displays though, I havent seen one yet that has worked simultaneously with the radio. They cant all have a library or memory conflict- which is why I was wondering if anyone else tried and thought maybe it was a power problem. I think if you do not use a I2C or SPI it will work.

I went with the inseton hub as I still have some X10 stuff. I will wait on OpenHAB2 for now, 1.7 runs fast for me a motion node > gateway > inseton hub > light is so fast I was surprised <1sec |

Wow...I hate the dashboard didn't work out. I'll let you know how I make out with it, but the code looks super simple to debug...but I understand your point about the WAF...for you there wasn't much use to continue! I dont think I want the tacky thing on my wall either...a clear tent shaped stand on my kitchen bar will look pretty though. I'm surprised you dont think it will work with SPI...just needs what would normally been pin 10(SS) moved somewhere else and the code changed appropriately, no? I have a couple of these: www.ebay.com/itm/2-4-TFT-LCD-Shield-Socket-Touch-Panel-Module-for-Arduino-UNO-R3-New-UF-/161858756204?hash=item25af889e6c:g:zmkAAOSwhcJWH3qB It's small, but the whole rig may fit in a light switch box. A safe way I like to do it with mains is bring the wires into the box, right into a cheap cell phone charger, and shrink wrap them onto the prongs. Then the whole thing will be touch safe. For me the safety is as important as looking good. |

I don't know much about using the LCDs though I did recently get the computourist LCD End Node working. When I first started with this project, I had big gaps in my understanding & was trying to use it the wrong way.
I was also concerned about using so many digital pins with the parallel hookup of the LCD & wanted to try something like I2C. Computourist's reply might offer some clues:
I tried some LCD things with I2C, but no luck, especially since I was so newbie at the time. For the moment the LCD is not a high priority for me, but I would welcome progress on this.

Some time cheap boards will load or interfere with the SPI only way is to try. |
