LCD problem

[skyseb]

hello,

 

i have a problem with the IDE arduino, because, i can't print a float on the LCD.

i use Arduino -102, for ZPUINO.

 

when i want to print a float in the lcd, the value stay frozen at "0. ".

 

have you any idea about this problem?

 

thanks

hmmm, can you post your code? It might give us some more information to go from.

We don't quite support floating point.... but should work. What was the binary sketch size ?

 

If you do a Serial.println() of the floating point, does it work ?

[skyseb]

for example when i write:

 

float Val;

lcd.print(Val); 

 

the program doesn't launch and the lcd stay frozen at "0."

Ok let me do some tests over here.

okay thanks alvie

There seems to be some issue with floating point indeed. Looking at it right now.

[skyseb]

yes the point seems crash the arduino programm, because when i define a float, the program about the arduino crash and the lcd print "0.".

Let me know if it works.

if you can, locate the temporary build folder and zip it and send it to me. Are you using Windows, Mac or Linux?
