Can I define the CPU speed in the compiler without having to use define statements in each source file?

At first, try at 1Mhz, or 8Mhz.

I made a typo above I meant to say ds18b Are you using avr-gcc as compiler? Try the DS18B20 on other platform, like Arduino, just to make shure the sensor is working. Davide Gironi November 18, at Posted by Davide Gironi at Unluckly, the only way to check it is to scope on that pin.

Rao SiGe July 30, at 7: I have been traveling all summer so I’ve not tested it with negative temperatures yet. Davide Gironi September 9, at 9: Also you can check the bus of the sensor. Hi again, I tried in Arduino and it works.

Un indicazione questa molto lontana da quella che dovrebbe essere la temperatura ambiente o quella corporea. Davide Gironi April 21, at Previously I did check to ensure that the ext clk was 16mhz. Is the setting correct??
