PSoC 4 MCU

I want to integrate the DS18B20 sensor. I was seeking one-wire component and found on the web that earlier there was component available but in CY8CKIT-042 PSoC 4.3 it is not available anymore. Also, I had seen someone has written you can use "Digtal Ouput Pin" for one-wire communication. But I was wondering then from where onewire.h library I will get.

Could you please help me. I may be asking a very basic question but I am a beginner in cypress.

Thanks in advance.

Hello Vasanth,

I had already checked this link. For CYBLE-0220001-00 device it says “onewire is not supported to selected device.”

Hi,

The component needs UDB blocks to funciton. There is bit-banging project available.PSoC4: Bit Banging 1 Wire Protocol (DS18B20 Thermometer) - Hackster.io
