Oh sorry, the first .ino i posted, the line would be 483!!
on the later .zip file with libraries its line 632 the function “m2_service()” starts, thats the function that causes the problem, since the serial Print “Service Cycle Nr:” gets executed a few times before bricking.
For trying i removed the switch’s case 1 (line 645) content, but this DID NOT solve the problem
About DOG.string. I use this in other parts of the code way much and faster - no problem.
Here is the fucntion from the library that executes DOG.String
void dog_7565R::string(byte column, byte page, const byte *font_adress, const char *str)
{
unsigned int pos_array; //Postion of character data in memory array
byte x, y, column_cnt, width_max; //temporary column and page adress, couloumn_cnt tand width_max are used to stay inside display area
byte start_code, last_code, width, page_height, bytes_p_char; //font information, needed for calculation
const char *string;
start_code = pgm_read_byte(&font_adress[2]); //get first defined character
last_code = pgm_read_byte(&font_adress[3]); //get last defined character
width = pgm_read_byte(&font_adress[4]); //width in pixel of one char
page_height = pgm_read_byte(&font_adress[6]); //page count per char
bytes_p_char = pgm_read_byte(&font_adress[7]); //bytes per char
if(type != DOGM132 && page_height + page > 8) //stay inside display area
page_height = 8 - page;
else if(type == DOGM132 && page_height + page > 4)
page_height = 4 - page;
//The string is displayed character after character. If the font has more then one page,
//the top page is printed first, then the next page and so on
for(y = 0; y < page_height; y++)
{
position(column, page+y); //set startpositon and page
column_cnt = column; //store column for display last column check
string = str; //temporary pointer to the beginning of the string to print
digitalWrite(p_a0, HIGH);
digitalWrite(p_cs, LOW);
while(*string != 0)
{
if((byte)*string < start_code || (byte)*string > last_code) //make sure data is valid
string++;
else
{
//calculate positon of ascii character in font array
//bytes for header + (ascii - startcode) * bytes per char)
pos_array = 8 + (unsigned int)(*string++ - start_code) * bytes_p_char;
pos_array += y*width; //get the dot pattern for the part of the char to print
if(type != DOGM132 && column_cnt + width > 128) //stay inside display area
width_max = 128-column_cnt;
else if(type == DOGM132 && column_cnt + width > 132)
width_max = 132-column_cnt;
else
width_max = width;
for(x=0; x < width_max; x++) //print the whole string
{
spi_out(pgm_read_byte(&font_adress[pos_array+x]));
//spi_out(pgm_read_byte(&font_adress[pos_array+x])); //double width font (bold)
}
}
}
digitalWrite(p_cs, HIGH);
}
}
Sorry, i know the code is a mess, but i’m developing. Sorry for missing libraries…
