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.

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

Have you tried a different sensor. It could be that the current sensor is faulty as the code looks to be correct.
What's the cable length between the chip and the sensor. I have 18B20's in a...

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

I tried all values from 2.2k to 10k, same "85".

Here is complete code

AMICUS

What is Amicus18?

Amicus is a multifunction development system inspired by the popular Arduino board, however, the Amicus board uses a Microchip PIC^® microcontroller instead of an Atmel AVR^tm type.

Comprehensive documentation and a helpful and friendly support environment, make using Amicus18 an easy and enjoyable experience for beginners and seasoned programmers.

Forum Moderator Mackrakit (Dave) very kindly ported the Proton BASIC Compiler code over to PBP3 and modified the original AMicus18 docuemts for PBP3 users.

Companion Sheild

The entry level shield is labelled The Companion Shield. This is a PCB laid out in the pattern of a solderless breadboard. The holes are single sided, which means that components can easily be removed using solder mop braid, or a solder vacuum tool, if a mistake is made, or components need to be re-used.

The (PBP3) Companion Shield Manual iCan be downloaded from here

GPS Shield

The Amicus GPS shield contains a multi channel GPS receiver, as well as a 16k byte (128 kbit) serial (I2C) eeprom, and a 3 Volt, 12mm battery socket in order to maintain the receiver's built-in RTC (Real Time Clock).

Available in our on-line store
