Hey,
has anybody made custom characters which are more descriptive than "LK" example?
I somewhere saw pictures, where somebody had made custom characters for example "L/100km" - it was made with 2 chars - first char was showing "L\n/1" and second "km\n00" - "\n" means newline - so imagine it as
"L/ km"
" 100"
Would be nice to know how to make them or link where I can get info.
One good hack/optimisation for code also:
I put clear screen commands before every screen change - now that half second when it shows screen name, it is only name - second line is clear. Now you can delete all trailing spaces in screen names and other strings. As a result you should save some bytes (did not count but it was less than before and screen names are clear to read)
inside setup()
Code:
LCD::LcdCommandWrite(B00000001); // clear display, set cursor position to zero
LCD::LcdCommandWrite(B10000); // set dram to zero
//LCD::gotoXY(0,0); //no need for it, clear display already made gotoxy(0,0)
//LCD::print(getStr(PSTR("OpenGauge ")));
LCD::print(getStr(PSTR("OpenGauge")));
//LCD::gotoXY(0,1);
//LCD::print(getStr(PSTR(" MPGuino v0.75")));
LCD::gotoXY(2,1);
LCD::print(getStr(PSTR("MPGuino v0.75")));
inside loop()
Code:
//LCD::gotoXY(0,0); //no need for it, clear display sets it gotoxy(0,0)
//is any of three buttons is pressed, clear display
if( !(buttonState&lbuttonBit) || !(buttonState&mbuttonBit) || !(buttonState&rbuttonBit) ){
LCD::LcdCommandWrite(B00000001); // clear display, set cursor position to zero
}
//see if any buttons were pressed, display a brief message if so
if(!(buttonState&lbuttonBit) && !(buttonState&rbuttonBit)){
LCD::print(getStr(PSTR("Setup"))); //remove trailing spaces "Setup " -> "Setup"
initGuino();
}
//....code continues
