Temperature measurement with DS18B20 sensor.
Budget: $30 – $250 USD
Hello,
I need a code to read the temperature from the DS18B20 sensor. It stores the measured value in 2 char variables and converts it to a string.
Processor : PI32MX120F032B
Compiler : C32 v2.02
MPLAB X IDE v5.20
PIC32 crystal : 8 MHz
Input/output pin : RB2
Temperature measurement - resolution : 12 bit
To Do:
1. software for PIC32MX120, which reads the temperature and stores the result in 2 char variables (low_value, hign_value).
2. It then creates the resulting temperature value as a float variable and converts it to a string.
3. The software measures both positive and negative values.
4. The resulting code will be based on a 1-wire library from Microchip.
Use the Delay1us (xx) and DelayMs (unsigned t) functions for the delay function. Attached is my application. You add code to the GetTemperature() function.
Thank you.
