Temperature reading from DS18B20 on PSoC 5LP

[NaAh_4673366]

Hi everyone,

I want to read the temperature from a 1-Wire based digital thermometer DS18B20 and show it using UART communication. Can you tell me

how to do it as PSoC Creator 4.2 has no 1-Wire component?

I am using CY8CKIT-059PSoC5LP

Someone actually created a custom component to interface with that sensor:

Component to read DS18B20 digital temperature sensors

Without this though, you'd have to write the read/write functions in the firmware.

Hi,

I just write code but when I run it, it always shows 127° celcius. Can't find out the reason. can you help?

Hi,

Another bit banging example you can have a look at
