## Detailed Description

Renesas communication board HAL.

The ComBoard HAL is used to provide access to Renesas Environmental Sensors through a communication board that is connected to the users PC. The ComBoard HAL supports both, the new ESCom board and the old HiCom board. Some sensors might not be working with the HiCom board, as this board does not support clock stretching.

The ComBoard HAL is implemented in file src/hal/comboard/comboard.c. The HAL functions use the ESCom Board API and HiCom Board API to discover connected communication boards and initialize the Interface_t hal object function pointers appropriately to operate the sensor.
