ATMEL AVR ATMEGA DS18x20 library in C Download

Beschreibung:

The driver routines have the following features:

1. Temperature range: -55°C to 125°C
2. For positive temperature values one can have 1 decimal place step size i. e. 0.1°C (however only 0.5°C measurement accuracy is guaranteed)
3. For negative temperature values the step size is 0.5°C
4. The return value of the ds1820_read_temp(uint8_t DS1820_pin) is float. This is not the most efficient way on a 8bit MCU but I think this is an easy way to get started.
5. Only one sensor per ATMEGA Pin can be used
6. For short wire length (less than one meter) from DS18x20 to ATMEGA MCU the internal pullup resistors work. For longer wires you need an external 4.7k pullup resistor
