Hi together,

I got stuck at an actual project at home. Besides some sensors and actors (which all are working fine), I have some trouble with the display. Hardware wiring was no problem at all, programming is a problem. Here my setup:

Microview on a breadboard, resistors, wires, bubble display.

According to the Sparkfun Learnpage (here: https://learn.sparkfun.com/tutorials/bu ... okup-guide) we have to pinout the HP Bubble Display:
Code: Select all
  //This pinout is for a bubble dispaly
   //Declare what pins are connected to the GND pins (cathodes)
   int digit1 = 8; //Pin 1
   int digit2 = 5; //Pin 10
   int digit3 = 11; //Pin 4
   int digit4 = 13; //Pin 6

   //Declare what pins are connected to the segments (anodes)
   int segA = 7; //Pin 12
   int segB = 6; //Pin 11
   int segC = 10; //Pin 3
   int segD = 3; //Pin 8
   int segE = 9; //Pin 2
   int segF = 4; //Pin 9
   int segG = 2; //Pin 7
   int segDP= 12; //Pin 5
But now comes the problem, as the Microview uses the Pins 0-6 and A0-A5. According to this page here http://learn.microview.io/intro/general ... oview.html. So after wiring and including the library in my Arduino project, I just adjust the pin declaration:
Code: Select all
  //This pinout is for a bubble dispaly
   //Declare what pins are connected to the GND pins (cathodes)
   int digit1 = A0; //Pin 1
   int digit2 = 0; //Pin 10
   int digit3 = A1; //Pin 4
   int digit4 = A2; //Pin 6

   //Declare what pins are connected to the segments (anodes)
   int segA = 1; //Pin 12
   int segB = 2; //Pin 11
   int segC = A4; //Pin 3
   int segD = 5; //Pin 8
   int segE = A3; //Pin 2
   int segF = 3; //Pin 9
   int segG = 6; //Pin 7
   int segDP= A5; //Pin 5
But when I now try to compile my project, I get a lot of errors. And they all result from the fact, that the "SevSeg.h" library can't handle the variables filled with A0-A5.

Does anyone know how this can be fixed? Can this be fixed by changing the "SevSeg.h" library?

Thanks and regards,
Robert

It compiled fine for me with your changes.

Here's the complete sketch that I used:

 This sketch provides a simple counter example for the HP Bubble display from SparkFun.

Hi together!

First of all: IT WORKS! Perfect!

But it wasn’t actually the code that was wrong because the scratch from scotta didn’t compile ether. So I had to look somewhere else and finally found the problem. My Arduino IDE was set to Adafruit Trinket / USBtinyUSP and not to Arduino UNO / Com1. And that was the problem. Two weeks ago, I tested something on the Trinket and changed those settings.

With correct settings, everything worked. Even my old scratch.

Regards,
Robert
