string set selection

Just got two readerboard kits (thanks!) and set one up on a proto board to play with. All seems to work well except for one thing: selecting string sets to display. When I pull pin 8 to ground - either by tying it to pint 10 or to the ground rail - the readerboard alternates between the two string sets on each power-on. I've tried new jumpers, etc. - everything but switching to a new proto board. Looking at the code, I don't see any provisions for alternating string sets... Smile Note: it increments each string set on power-on; the issue is alternating between sets.

Suggestions welcomed!

If you look in the code at the definition of StringSet2, it does alternate between the "holiday" strings and the "regular" strings:

PHP Formatted Code

const char String0[] PROGMEM = "I AM SHOWING OFF MY PROGRAMS    ";  //String0 will rotate through all strings.

const char String1[] PROGMEM = "PLEASE CHANGE MY BATTERIES    JUST KIDDING   HAVE A NICE DAY    ";

const char String2[] PROGMEM = "HELLO WORLD     ";

const char String3[] PROGMEM = "I SOLDERED THIS MYSELF     ";

const char String4[] PROGMEM = "MAKE   TECHNOLOGY ON YOUR TIME     MAKEZINE DOT COM     ";

const char String5[] PROGMEM = "HELLO   I AM AN OPEN SOURCE MICRO READERBOARD     ";

const char String6[] PROGMEM  = "MAKE    ";

const char String7[] PROGMEM  = "MAKE IT    ";

const char String8[] PROGMEM = "THIS DISPLAY USES ONE HUNDRED PERCENT RECYCLED ELECTRONS     ";

const char String9[] PROGMEM  = "MAKE DONT TAKE    ";

const char String10[] PROGMEM = "MAKER    ";

const char String11[] PROGMEM = "MAKE STUFF     "; 

const char String12[] PROGMEM = "EVIL MAD SCIENTIST DOT COM    ";

const char String13[] PROGMEM = "I HEART ELECTRONICS    ";

const char String14[] PROGMEM = "DUDE    NICE BLINKYLIGHTS      ";

const char String15[] PROGMEM = "JOIN THE RESISTANCE      USE KIRCHHOFFS RULES AND OHMS LAW       ";

const char String16[] PROGMEM = "A SUBSCRIPTION TO MAKE MAGAZINE MAKES A GREAT GIFT     ";

const char String17[] PROGMEM = "THESE ARE NOT THE PRESENTS YOU ARE LOOKING FOR   MOVE ALONG     "; 

const char String18[] PROGMEM = "WARNING  WARNING   THIS TREE WILL SELF DESTRUCT    ";

const char String19[] PROGMEM  = "I AM IN UR TREE BLINKIN UR LITEZ      ";      

const char String20[] PROGMEM = "ORNAMENT     ";

const char String21[] PROGMEM = "LET IT SNOW  LET IT SNOW  LET IT SNOW    "; 

const char String22[] PROGMEM  = "I HOPE YOU SAVED SOME PRESENTS FOR US ORNAMENTS    "; 

const char String23[] PROGMEM = "HAPPY NEW YEAR     ";

const char String24[] PROGMEM = "ALL I WANT FOR XMAS IS A MICROCONTROLLER PROGRAMMER    ";

const char String25[] PROGMEM = "I AM THE VERY BEST ORNAMENT ON THIS TREE     ";

const char String26[] PROGMEM = "SANTA CLAUS IS COMING TO TOWN    LOOK BUSY      ";

const char String27[] PROGMEM = "BAH  HUMBUG      ";

const char String28[] PROGMEM  = "ALL YOUR GIFT ARE BELONG TO US      ";

const char String29[] PROGMEM  = "HAPPY HANUKKAH   ";

#define NoOfStrings1 16U                        //16U  //Number of strings. (String0 - String15 is 16 strings, total)

#define NoOfStrings2 30U                        //29U  //Number of strings. (String0 - String28 is 29 strings, total)

PGM_P StringSet1[] PROGMEM = 

{String0,  String1,  String2,  String3,  String4, 

 String5,  String6,  String7,  String8,  String9, 

 String10, String11, String12, String13, String14, String15

 }; 

PGM_P StringSet2[] PROGMEM = 

{String0,  String1,  String2,  

String3,  String17,  

String4,  String18,

String5,  String19,

String6,  String20,

String7,  String21,

String8,  String22,

String9,  String23,

String10, String24,

String11, String25,

String12, String26,

String13, String27,

String14, String28,

String15, String29,

String16

 };

StringSet2 is the one activated when you ground that one pin. Are you *sure* that it's not just following the order defined here for StringSet2?

OK. Darn it, as a decades-long software slinger and QA hack, you'd think by now that I would read code for what's there - not what I want it to be. Oops!

If only my wife would sit still for my "read the code to someone and explain it, and you'll see what's *really* there", I wouldn't feel so foolish!

Now: once my tinyusb programmer arrives, I'll fix that little behavior "quirk".

Thanks!
