- * @{
- *
- * As of version 2.0 you can now use more than just one one-wire "port" on STM32F4. This allows you to group devices to separate ports.
- *
- * Because if you have a loot devices on one port, if one device fail, everything is failed. You can prevent this by use more than just one port.
- *
- * To set your port and pin for OneWire protocol, you can do this when calling @ref TM_OneWire_Init function.
