The best formula I think is to calculate with the steinhart-hart equation. Perfect for unlinear Temperature Sensors.
You only have to use more Calibration Points that the accuracy is good. |

We are interested to implement a Firmwareloader like a Bootloader into our
Project with a PIC 18F2550, but we don't have any experience with this.
We use the PICWinUSB Example from Hobbypic.

Hi together!
I need to change the fuses during my program between HSPLL and INTHS with a PIC 18F2550, because of the power consumption.
In HSPLL mode I need the USB in FullSpeed with a 20MHz Osc (P ... |

No this is not the project I'm working on. It's for a Miniature Scientific Temperature Datalogger.
But it works now, also with cold temperatures (up to -40°C). I had a really stupid error.

We created a temperature datalogger with a PIC 18LF2550.
My problem is that they don't work with cold temperatures.
Now I put a external rectangular clock (0 to 3.6V / 32.768kHz) into the RC0/T ... |
