(Solved)Again problem with matrix, this time 8x32

dafug? I did try initilazing that addr2 at void where it points at, but those others are mystery
errors:

C:

But, that code showed long bars lit in leftmost matrix, upload shot in a few

Here we go: (got teensy 3.2 today btw )

tiney eh? hows that workin so far? all i have used is the atmega2560 and just recently got it, so far if this is c++ i can't tell, from c#, im happy i havn't had to use the confusing symbols from that lang so far... this conversion is common when switching compilers, btw , what is the chip you are using for this array? if this works....i am going to look at that interrupt setup next, but hard to find proper example.

Teensy is cool, much more power and space in both flash & RAM and all considered better than UNO, coding is also done by arduino IDE when teensyduino is installed....too bad I forgot audio shield, then that would do pretty much all audio stuff, at least it has more than enough power for it. Tested 2.2" TFT and it's way faster than UNO.
What I use currently doggy is pro mini, atmega 328. Your code missed pin declarations, fixed those, screen show 01010101 drawn vertically, taking shot in a few

OK lookin good, almost there!, this time we are going to do a twist, goto Sketch, Add File, and create a new file in project library called FontMap.h, let me kno if any questions.
don t bother building yet.

In the FontMap file add this:

static unsigned char font [1000] = //numbers stored here

Hmm, I made file called FontMap.h, in libraby folder, inside FontMap.h folder, but still gives error saying

Adruino Compiler.....sketch....add file.....""

if it added it will show as a tab across the top, just under the "verify, build, ect..." buttons

no need for fontmap folder, just fontmap.h file, same folder as where the sketch file is

fezder · Jan 21, 2016

Hmm, ok with that same result, I see fontmap file in tab next to main skecth, it adds it ok but gives that error
FontMap.h is at same folder as sketch not

Dr_Doggy · Jan 21, 2016

is case sensitive...(>?)

alt-prtScn key will do a snap shot, or else add your project to zip file and upload.....

is working on my end.....

fezder · Jan 21, 2016

ehh? file types are INO in both skecth and h.file

Dr_Doggy · Jan 21, 2016

k, go to my computer, c , docs, adruino, "project folder, right click , add text file, name "FontMap.h" , ok to change file extention

Dr_Doggy · Jan 21, 2016

or try this:

fezder · Jan 21, 2016

oops, made that h.file wrong it seems, here's from your zip you sent:

Dr_Doggy · Jan 21, 2016

ya, its glitch in software, it just happened to me too when i was reviewing your steps... when it created the file it deleted the old but forgot to save new...

you will notice i expanded the font table, I started to fill it out , you will see in the // that first i show position, then character ,
so to call it you use the charput(position, x,y); <-- so x,y are the start points, then position calls the array at that position, which will display the character, so for example if position=9, then display will output 9.... if position= 65 it will display the letter "A", you will also notice that if position=57, it will also display "9". i did this cause 57 is the ascii text value for number 9

It is being arranged special like this so that it match the ascii value which will help when you want to put in a string with strput()

so now you can easily send a message out like this: strput("9", x,y); which will display 9, but is calling from ascii value, ie position 57.......... or strput("hi",x,y);

or to do a number value out like this charput(9,x,y); --which will display a 9 too! (calling from position9)

also this leaves position 10-31 to display your own character fonts
also i am writing this using the font type from my lcd screen , so if you dont like how character looks, feel free to edit map.

we can hold off on this though for now, i did cheater program to help

but first one last test an then ima go after the interrupt settings,.. so we can start to see results better

Dr_Doggy · Jan 21, 2016

void loop() //just sitting here
{
clr();
pixel(0,0,0);
pixel(31,7,0);
strput("WOOF",1,0);
Blit();
delay(500);
}

Dr_Doggy · Jan 22, 2016

after that ,
there are 2 occurrences happening in your code rite now called TIFR2, change them both to TIFR0,
then change this:

void setup() //setup runs once
{
noInterrupts(); // disable all interrupts during setup
DDRD = DDRD | B11111100; //port registers used to set pin directions

// Set the Timer Mode to CTC
TCCR0A |= (1 << WGM01);

// Set the value that you want to count to
OCR0A = 0xF9;

// start the timer
TCCR0B |= (1 << CS01) | (1 << CS00);
// set prescaler to 64 and start the timer

while ( (TIFR0 & (1 << TOV0) ) > 0) // wait for the overflow event
{
}

TIFR0 &= ~(1 << TOV0);
// reset the overflow flag
interrupts(); // enable all interrupts
} // End main

(Solved)Again problem with matrix, this time 8x32
