personally , I never use sockets , unless it's a reprogrammable part .
Like an mcu or an pld .
If you do use sockets , make sure you get the high-q ones with tulip
contacts .

Al ,

Tested it yesterday
The Celsius code is working fine .


Also , a tip for lcd users .
Many LCD's like a little negative voltage
on the contrast pin .
This can be achieved by tieing the ground pin of the contrast
potmeter to the V- ( pin6) of the max 232 instead of ground .
This allows ...

It wasn't me that asked for it , but I'll test it tomorrow .

A Celsius version of the MegaView download ...

I left it out because i needed space to implement the active flyback mod
on my pcb .
But it's true , there is a chance of 12V on the circuit .
Didn't think of that .

Oh well , let's be extra carefull now and nothing

Thx for the replys guys

Well , I am an EE .
That is why I posted this question .

If the other four adc inputs need no protection , then this one probably
won't need it either .

Pat

D1 , D2, D3, D4 are not needed , because the processor has internal
protection diodes .
What about D11 .
Can it be left away also ?
It looks like it has thesame function as the other four .
