I have a simple circuit, but it's not working as expected.
LM358 is used as simple comparator for slow input signal, it should detect when Vin goes above 2V (trimmed by POT). It works, but not as expected, ie when Vin is above Vref, Vout is only 0.8 V instead close to 5V. Tried new LM358...
Re: pic programming language
Try www.mikroelektronika.co.yu and look in mikroBasic and mikroPascal.
Nice compilers, demo can compile up two 2K of code (more than enough for education) and cheap too.
Same problem here. I've made measuring system with ATMEL's ATMEGA8515 and 12 DS18s20 and on room temperature 8 of them show difference of less than 0.3 celsius but 4 are way off. One actually shows 4 degrees lesser temperature (instead of 23 it is 19). Have no solution for this except to throw...
