I will try it. Thank you

Dear friends,

I want to read several DS18B20 and want to use the 1wire library.
I want to be flexible in the code and want to run the 1wire library more times.
So i need to declare a Port AND a Pin.

But how todo this?
This doesn't work:

Thank you

Hello,

For an application, i must know, how long take a 1 wire command,like:

Ow_Reset()
Ow_Write()
Ow_Read()

Also i must know, how fast ist the datarate. 16 kbit/s ?

Someone know this?

Found it myself:
OSC must be more then 500khz.
Set it to 16 Mhz and it work fine.

Hey guys (and girls), I have following problem: I want to read out the temperature of a DS18B20 But the DS18B20m always return "255". What I have tried: Another DS18B20 DS18B20 at the ext. Sensor clamps Pull up value changed. (1k,1k2,1k8,2k2,3k3,4k7) Another PIC12F1572 What is running: 5V on DS18B20...

Könnte dir da meine Hilfe anbieten.

Now all is working thank you

A little feedback: I tried following code, before sleep: PWM2CON.6 = 0 'Disable PWM output PWM2CON.7 = 0 'Disable PWM module TRISA.0 = 1 'Select RA.0 as input ANSELA.0 = 1 'Select RA.0 as analogue input (save energy) But it was not working. I move the PWM start/Init,.. to the hardware init procedure...

Ok. I understand. I will try to set the Tris Bits all to input, to save more power. After sleep loop, i will reinitialize the whole hardware. I run the sleep loop 6 times with WDT time from 16 seconds, because i will need ~96seconds. I could also do it with 3 X 32seconds WDT time. Would this the bet...

I don't need the PWM at sleep.
So thought, if i set the PWM clock to Fosc.
When it goes in sleep mode, PWM stop.

But you see it on the oscilloscope, that the PWM starts with highest duty cycle
This is the problem.
In sleep mode, the PWM should be low.

Hello Guys, I have a program with have following sequences: After startup: Analyse 30 sec. Sleep 96 sec. Analyse 30 sec. Sleep 96 sec. ... ... Now i have following problem: If the sleep command is executed, the PWM output increase/decrease randomly. (See attached files) Every time the sleep loop is ...

OK. It doesn't work

It hangs here: Somebody knows a solution for this?

Hello other users, I want to measurement the VDD voltage of a PIC12F1572 and send it via uart to the pc. I am not sure, if this code is working. I never have programmes PIC µC before. Can somebody take a look on it? 'Used Processor: PIC12F1572 'Internal oscillator with 500khz 'Measure VDD and send i...
