do you need to do that in asmsembler or you are free to choose the languaje?? you can use PCWH picc to program in c lenguaje! its esasier.. if not... giveme a chance and I will reply this with asm! I am currently busy with my thesis

I think I found something! the problem with normal current to voltage configuration is not due theory or something like that (of course not"!) but, it is related to the op-amp, it gets saturated too fast! even when I put it in a follower configuration, it gets saturation point and dosent follow...

ahh, now a got your cuestion, yes it is conected to 0v, its a dual supply, and yes, I now that I haven't discovered nothing new, but... what is wrong with a theoretical current to voltage circuit that I can't get it to work properly, I know electronics or almost enough to know when a 741 pin is...

Ive already done that, and nothing, iv tried several 741 cofigurations and nothing.. please if anyone can try this http://laser.physics.sunysb.edu/~tanya/report2/" or any configuration of current to voltaje converter to work with a LED letme know which one did u used. I am talkin do it in a...

done. :-)

done. done. done. one week at that. Trying everything

Im measuring between pin 2(-) and 6(+) but when I measure ouput pint relative to ground I have no output

is that what I am traying to say, this schematic is working but I havet documented it jet, I am just starting the measurements, but the schematic is exactly as I have in my protoboar working, the output at sunlight is at about 4v and in dark is 0.250v

Well, maybe I have to say that this configuration is actually running well, and I can't do anithing with that what you are showing to me... that's my problem,, Every standar circuit that I do fails, so I did find this configuration by mistake

Hi, no it is no a LED, I just used that symbol to figure out the diagram, it is a photodiode from inside an old mouse used to capt the movement of the ball, it is infrared, The circuit is totally strange because... , yes, it seems to be a traditional current to voltage but it is not, the output...

Im doing my thesis its about measure haze at ambient, so I found very little information about DIY schematics to work with photodiodes, at last my tutor found something, but when I was doing the circuit I found that this doesn't worked! well I made some mods and for a mistake I found a...
