Access Layer). РThis is a SW library developed to interface the USB driver and firmware running Рon the evaluation board, containing all the functions required to read/write data Рover the SPI interface between the USB MCU and the Transceiver or the debug Рinterface in case of a System-on-Chip.РFor proper operation of the applications using CEBAL, the board will need to Рpatible firmware running on the USB MCU. If the firmware is out of Рdate, SmartRF Studio 7 will propose that the user updates the firmware. The Рfirmware update can be done directly in SmartRF Studio 7.РSmartRF Studio 7 will send requests to the USB MCU. The USB MCU will handle Рthe request and apply the appropriate read/mands on the SPI or debug Рinterface.РThe USB driver is a licensed driver delivered by Thesycon: РР 10
