Issues with runnning TEA5767 and nixies at same time

hi guys!

just have brief overview of project, i'm making retro-style radio using tea5767 fm radio chip connected arduino via i2c. using arduinix shield power 4 in-17 nixie tubes. right now, arduino running program uses nixie tubes display time. i'll able use nixie tubes display station tea5767 tuned to. each part (the radio , nixie tubes) works fine itself, when combine 2 codes, nixie tubes flash on , off rapidly, , radio chip no longer tunes properly.

i used code fm radio chip: http://www.instructables.com/id/tea5767-fm-radio-breakout-board-for-arduino/step5/conclusion/

the original code driving nixie tubes can found here: http://arduinix.com/main/code/anx-4tube-clock-crossfade.txt


and finally, combined code:

thanks! appreciated!

any appreciated!

some links hardware using good.

code: [select]

int ledpin_0_a = 2;               
int ledpin_0_b = 3;
int ledpin_0_c = 4;
int ledpin_0_d = 5;

int ledpin_1_a = 6;               
int ledpin_1_b = 7;
int ledpin_1_c = 8;
int ledpin_1_d = 9;

int ledpin_a_1 = 10;
int ledpin_a_2 = 11;
int ledpin_a_3 = 12;
i thought said have nixie tubes. why don't these names reflect that?

this code:

code: [select]

  // note:
  // grounding on virtual pins 14 , 15 (analog pins 0 , 1) set hour , mins.
  pinmode( 14, input ); // set vertual pin 14 (pin 0 on analog inputs )
  digitalwrite(14, high); // set pin 14 pull resistor.

  pinmode( 15, input ); // set vertual pin 15 (pin 1 on analog inputs )
  digitalwrite(15, high); // set pin 15 pull resistor.
is not compatible code:

code: [select]

   int reading = analogread(0);

analog pin 1 , digital pin 14 same pin, on 328-based arduinos. 1 purpose want use for?
