Need help with Adafruit RGB LCD 16x2 for Arduino Uno

hbajwa · June 21, 2021, 1:36am

I wanted to have a fancy interactive display for my Arduino temperature controller. That is proving to be challenge because there's something wrong with jm_LiquidCrystal_I2C.h library. I am sure there's many more problems with the code as it is 5 years old and not my creation. I found it here from Instructables. The triple slash is for the future temperature probes i may add for additional fermenters. Currently i only have one probe attached. The sketch code that i have changed to my needs is this:

/* Multiple DS18B20 Temperature Sensors on 1 wire
   for controlling heating or cooling of muliple fermenters.
*/   
/*-----( Import needed libraries )-----*/
// Get 1-wire Library here: http://www.pjrc.com/teensy/td_libs_OneWire.html
#include <OneWire.h>

//Get DallasTemperature Library here:  http://milesburton.com/Main_Page?title=Dallas_Temperature_Control_Library
#include <DallasTemperature.h>

/*-----( Declare Constants and Pin Numbers )-----*/
// Digital pin 2 for all the DS18B20 data lines.
#define ONE_WIRE_BUS_PIN 2

#include <Adafruit_RGBLCDShield.h>
#include <Wire.h>
//#include <LCD.h>
#include <jm_LiquidCrystal_I2C.h>
#include <jm_Scheduler.h>
#include <jm_Wire.h>



/*-----( Declare objects )-----*/
// Setup a oneWire instance to communicate with any OneWire devices
OneWire oneWire(ONE_WIRE_BUS_PIN);

// Pass our oneWire reference to Dallas Temperature.
DallasTemperature sensors(&oneWire);

/*-----( Declare Variables )-----*/
// Pre-assign the addresses of your 1-Wire temp sensors.
// See the tutorial on how to obtain these addresses:
// http://www.hacktronics.com/Tutorials/arduino-1-wire-address-finder.html
// Uncomment the following lines for preassigning the addresses to the probes variable

DeviceAddress Probe01 = { 0x28, 0xFF, 0xFB, 0x74, 0x44, 0xE0, 0x48, 0x66 }; 
//DeviceAddress Probe02 = {  };
//DeviceAddress Probe03 = {  };
//DeviceAddress Probe04 = {  };
//DeviceAddress Probe05 = {  };

//Relay digital write pins on Arduino

int Relay2 = 6;

I tried to guess what library i should use but there are so many to choose from. Please help however you can!

noiasca · June 21, 2021, 4:26am

I suggest you start from scratch.

test the Adafruit RGB display with Adafruit RGB Library
test the DS18B20 with one of the examples provided with the Dallas examples

Check if both sketches are working separately.
If so - add the Adafruit RGB LCD things to the Dallas sketch.

hbajwa · June 21, 2021, 9:07am

I am beginning to understand what may the problem be. I realized the LCD shield i bought is this one. That claims to be RGB but it is only blue and white! I tried running the code for it called HelloWorld.ino from the folder Adafruit_RGB_LCD_Shield_Library.

When i press the right and left buttons after uploading the code, it goes dark because i suppose it doesn't understand what to make of the colors blue, green, and teal. It only lights up for red, yellow, and violet. My attention to detail failed and i got the wrong thing. I will test the thermometer probe by itself soon.

noiasca · June 21, 2021, 9:42am

I assume the product just shares the PCB with the RGB version - the description is pretty clear saying "blue/white".
The RGB version costs around 5 USD more.

back to your blue/white: "At this time, the library and shield can control the backlight of our character LCDs by turning the LED on or off. "

I suggest you start with the Hello World example and remove all

[url]https://github.com/adafruit/Adafruit-RGB-LCD-Shield-Library/blob/master/examples/HelloWorld/HelloWorld.ino[/url]

and comment or remove all "lcd.setBacklight(xxx);" lines.

I can't see to which pin the LCD-Cathode is connected in case of your single color, but I assume it's the "RED" line GPA6.
So you could try to switch between RED (=might be on) and a single color like BLUE (might switch RED off) .

hbajwa · June 22, 2021, 1:05am

ok so i tested both components individually using the library examples. They work fine. I learned from that and replaced those libraries with the ones i had before. After looking it over again i fixed a few more issues in the code but thats not related to displays. I wished i had a better understanding of how to use lcd.setCursor() and how to declare something in the scope. Still there are two problems with the LCD. The new code is:

If there are problems off topic, please suggest the right tag i need to make another post.

noiasca · June 22, 2021, 1:23am

this is not the way to create a lcd object.

see again the original sketch how to make the lcd instance.

hbajwa · June 22, 2021, 2:19am

After googling it, I got another library that has the bold red color when fully written out called LCD_I2C.h

I changed it to LCD_I2C lcd(0x20,2,1,0,4,5,6,7,3);

Now the error message is not about the first part. It says:

all-seasons-temp-controller:63:33: error: no matching function for call to 'LCD_I2C::LCD_I2C(int, int, int, int, int, int, int, int, int)'
 LCD_I2C lcd(0x20,2,1,0,4,5,6,7,3);
                                 ^

if i try to leave the POSITIVE word in, it says 'POSITIVE' was not declared in this scope and puts the ^~~~~ under it. I got no clue what the POSITIVE does but assume it has something to do with the lcd. I will try to understand what those numbers are after the lcd address.

noiasca · June 22, 2021, 2:34am

it makes no sense to try just another library and to hope for a small wonder that your problem disappears.

You have prooven the Adafruit display to work with the Adafruit library - so use that combination correctly. Read again the error message from the compiler:

expected unqualified-id before numeric constant
 Adafruit_MCP23017(0x20,2,1,0,4,5,6,7,3,POSITIVE);

read again my post #4.

read again in the example sketch from Adafruit:

Adafruit_RGBLCDShield lcd = Adafruit_RGBLCDShield();

this makes an instance of the lcd object.

hbajwa · June 22, 2021, 3:05am

I didnt know what an object was so i didnt know what to look for. This is only my second Arduino thing i am making. I dont have anyone to tell me what is right so I am really confused all the time.

hbajwa · June 22, 2021, 7:47pm

ok i did that and i am left with two errors now. None of them are to do with the display. Thanks for your help
