DS18B20_OneWire

One Wire Temperature Sensor Breakout Board on Arduino Shield Format and STM32 Nucleo-F446 Based Software

Features

• four channels 1-Wire Interface with onboard driver stage
• designed for DS18B20 Temperature Sensor but any 1-Wire Sensor / Actor would do (minor software adjustments required)
• Industrial ready CAN-Bus interface
  • works with standard (11-Bit) and extended (29-Bit) CAN identifier
• Industrial ready Modbus interface will come soon
• Arduino-Shield layout will fit on several Dev-Boards including all Nucleo-64 boards and Arduino-UNO boards

The 1-Wire Search Algorithm and Driver Stage are basically taken from MAXIM Datasheet and Microship App-Notes.

To study some of my testing done so far please have a look here.

Quattro Formaggi vs. Quattro Stagioni

ToDo

• add User-LED on Arduino Shield (Nucleo LED is covered) [HW]
• add Temperature Results to CAN Message [SW]
• use bigger terminal blocks for 1-Wire Interface [HW]
• use bigger terminal blocks for Power Supply and CAN [HW]
