how to print data from sensors? #57

Closed Indra-nil closed 3 years ago

Indra-nil commented 3 years ago

hi, recently i'm using lcdgfx library due to low resource consumption. the only problem is that i'm unable to print raw and calculated float data from sensors to LCD. i'm using, display.printFixedN (XX, XX, "XX", STYLE_NORMAL, FONT_SIZE_4X);

but this command only supports string value.

thanx for the suggestion that's working. I also tried #44 example u gave but that didn't work at all only showing "?".

"Due to some performance reasons %f is not included in the Arduino's implementation of sprintf()" instead of sprintf() one should use dtostrf() "dtostrf(temp, 3, 2, str);" some links : [(https://stackoverflow.com/questions/27651012/arduino-sprintf-float-not-formatting)] [(https://arduino.stackexchange.com/questions/26832/how-do-i-convert-a-float-into-char)]

thank you by the way.

Oh, my bad. I'm sorry to mislead. Well, I will prepare the fix soon.
