I am using u8glib
I am trying to display battery voltage. Right now, i simplified to try to just display random integers
char bVoltStr; itoa(random(0,10),bVoltStr,10); u8g.drawStr(0,12,bVoltStr);
is in a loop
What i get on the screen is (each line is an update)
3 4 9 some wierd upsidedown 3 some strange diagonal usidedown question mark looking thing 5 Z .....
I should only ever be getting integers. HELP please :)
