Hi All,

i am now playing with SHT75 humidity and temperature sensor and got the temperature and RH reading in float number format. However, how can i show the result on the text LCD?

Thanks in advanced.

kit,
if you are using C (which I assume) you can use the fprintf function (sometimes this function differs slightly from the ANSI C standard, but your compiler doc should clarify this). Normally it is included in stdio.h. Using the fprintf function you can use modifiers or type specifiers to automatically convert the datatype. this would then look something like

fprintf(*Buffer, %f, float_value)

where *Buffer is a memory location that you simply swap to the LCD screen.

Hope this helps,
Cheers
