5 Hardware Tools and Development

The ATA8352 UWB device is connected to a host MCU using an SPI communication link with additional control lines for interrupt and reset functions. In addition, the device has 5 GPOx lines, which are optionally used in test and debug modes to measure and observe the internal device operation.

The SAM C21 MCU can be debugged and programmed with the help of a debugger (ATATMEL-ICE) or direct USB connection between the MCU host controller debug USB port and a computer. For more information, refer to the Microchip Debugger Atmel-ICE (ATATMEL-ICE) User Guide.
