Hi,
I have a feeling that making buff1, buff0 ON, it makes ADC work in Unipolar,
I am using internal temp on ADC1 and one input on ADC0 on ADuc845, I would like to use ADC0 in bipolar, buff, but when I do buff on with 0V on input I got from ADC 0x00 which in bipolar is -full scale, when buff is Offf, I got around 0x800000 which is OK, I think could please advise what I did wrong. Thanks in advance. Slawek
ADC1CON = 0x0E; ADC0CON1=0x07; //buff on is 0x87 ADC0CON2=0x05; ADCMODE = 0x24; ADCMODE = 0x25; ADCMODE = 0x3A; SF = 0x03;
my heart goes out to you, erik.
why?
you of all people should know that I post on weekdays.

OP: In this business brother, and I _know_ just about anybody here agrees with me, nerve of steel and a supreme amount of patience are of the highest importance you can imagine.
That is because quite a few problem are exotic; To demonstrate how exotic, you should know that I have created a "war stories" file for the last 2 projects I designed and later (partially) coded which contains details of interesting failure encountered during development for the sake of future problem solvers/maintenance. Sometimes it is really hard to find problems - sometimes questions remain lingering until the end of life of the product.
