Re: Stable Adc Reading Routine

Hi ! Me, again :)
Please, how to addapt Melanie's great pice of code (post#^6) for only 5 readed values, not 10 ?
Thanks !

Re: ADC input signal filter selection

I prefer the inductor on the +Vdd side.

Anyway, I'd suggest get 10 or more samples in an array, then sort them in order and keep the middle 5 values.

Then add them together and divide by 5.

Re: It is Y2K19 but DS18B20PAR+ Returns either 127 or 85 depending on resistor value.

Yes, the LATD.1 = 1 has to be set as there is no telling what state it was left in after the preceding OWOUT command.

Re: Need to drive 40 pins on variable change, is there a way to do it in elegant way?

won't statement HIGH DIGIT1(2) set HIGH the port number, stored in DIGIT1(2) ?

Re: It is Y2K19 but DS18B20PAR+ Returns either 127 or 85 depending on resistor value.

Excellent!
now it works!

so it was latd/trisd issue as I guess...

Re: Serin2 data bits

Within PBP you can manually manipulate SFRs, read and write to UART registers, etc. If the PIC you are using has EEPROM, you can set up an array of sequential EEPROM addresses with SFR settings. It...

Re: It is Y2K19 but DS18B20PAR+ Returns either 127 or 85 depending on resistor value.

Try this routine:

OWOUT DQD, 1, [$CC, $44] ' Start temperature conversion
LATD.1=1 SET PIN STATE TO HIGH
TRISD.1 = 0 'MAKE PIN AN OUTPUT WITH DEFAULT STATE HIGH
pause 760 'ADD AN EXTRA 10...

Re: It is Y2K19 but DS18B20PAR+ Returns either 127 or 85 depending on resistor value.

CuriousOne, How many times are you letting the program cycle? Here is the output from my terminal after I reset the processor power. Notice the "85" as the first reading from the DS18B20-PAR. This...

Re: PORTA.5 not responding on 16F18346??

YUP it wasn't OSCCONx per se, but you got me thinking and it WAS the Configuration Word Settings. I had (erroneously) assumed that by setting INTOSC at 32MHz, no other config word settings would be...

Re: It is Y2K19 but DS18B20PAR+ Returns either 127 or 85 depending on resistor value.

Yes tried another one, same "85". There is no cables, sensor directly hooked on breadboard.
