Hello,

Firstly apologies if this is very thick question, pretty new to all this electronic malarkey, had a look on the forums and couldn't find an answer, any help really really really appreciated.

I am wanting to read a voltage value on the RA0 pin on the pic 18f452 using ADCin. However the values I want to read go from 0.0 to 0.5 V.

Am I correct in thinking that because the pic doesn't do floating point values, anything less than 0.5 will be scaled down to 0?

If so, does this mean that your ADC converter can only supply a range of values from 0 to 5?

Thanks very much
Mark
p.s. I come from a software background, embedded hardware programing so much harder than just pure software, don't know how you guys keep your patience
