Examples and demos
Various examples are provided for fast library evaluation on embedded systems. These are prepared and maintained for 2 platforms, but could be easily extended to more platforms:
WIN32 examples, prepared as Visual Studio Community projects
ARM Cortex-M examples for STM32, prepared as STM32CubeIDE GCC projects
Warning
Library is platform independent and can be used on any platform.
Example architectures
There are many platforms available today on a market, however supporting them all would be tough task for single person.
Therefore it has been decided to support (for purpose of examples) 2 platforms only, WIN32 and STM32.
WIN32
Examples for WIN32 are prepared as Visual Studio Community projects. You can directly open project in the IDE, compile & debug.
To run examples on this architecture, external USB to UART converted would be necessary. Application opens COM port and sends/receives data directly to there.
Tip
Push-pull to open-drain external converter might be necessary. Check Hardware UART connection with sensor for more information.
STM32
Embedded market is supported by many vendors and STMicroelectronics is, with their STM32 series of microcontrollers, one of the most important players. There are numerous amount of examples and topics related to this architecture.
Examples for STM32 are natively supported with STM32CubeIDE, an official development IDE from STMicroelectronics.
You can run examples on one of official development boards, available in repository examples.

Pins to connect to 1-Wire sensor:
MTX: MCU TX pin, connected to 1-Wire network data pin (together with MCU RX pin)
MRX: MCU RX pin, connected to 1-Wire network data pin (together with MCU TX pin)
TX pin is configured as open-drain and can be safely connected directly with RX pin
Other pins are for your information and are used for debugging purposes on board.
MDTX: MCU Debug TX pin, connected via on-board ST-Link to PC
MDRX: MCU Debug RX pin, connected via on-board ST-Link to PC
Baudrate is always set to
921600bauds

LwOW bare-metal
Simple example, not using operating system, showing basic configuration of the library. It can be also called bare-metal implementation for simple applications.
