CCS DS18B20 DRIVER

Can anyone tell me how can I correct this? I found a few good 1-wire drivers for CCS C especially for these devices: The value of the pullup resistor is not critical. This code will not work with 2 or more DS sharing the same 1-wire bus. Thu Jun 18, 7: CCS does not monitor this forum on a regular basis.

PIC C, CCS, Interfacing with a Dallas DS Thermometer

Hi ds1b820, I’m using the original code posted by Han Solo on the first page, and I can’t get a temperature other than 85 C, which I think I read was the startup temperature. I tried your codes but the 18B20 returned very high temperatures – 85 degrees for example.

As far as I can remember, the If I use the updated code from http: Comentario por Astri Andrada — 29 agosto This code will not work with 2 or more DS sharing the same 1-wire bus.

Julio Castillo – Comunicaciones March 1, at 6: And if your problem is not ccw simulation, remember to attach the pull-up resistor to the 1-wire bus. The value of the pullup resistor is not critical.

I am using compiler 4. The microcontroller is connected to 4 temperature sensors. Comentario por HPantoja — 8 enero OneWire bus port pin: An almost unlimited number of 1-WireTM devices can be connected to the bus because each device has a unique bit ROM code ds18g20 which is used to address each sensor.

Has anyone else met this problem?
