The Firmware package contains all the HAL Driver and CMSIS modules covering the STM32L05xx, L06xx, L07xx, L08xx devices and provides project Examples on the four proposed boards (262 Examples - 42 Applications - 4 Demos) It is recommended to carefully read the readme.txt of each Example or Application, especially for the STM32L073Z_EVAL board, because some specific position of Jumpers are mentionned. And to follow the two required positions of the LCD Glass (in IO mode by default and in LCD mode for the LCD Application project). It is also recommended to set back the LCD in IO position afterwards.
