ATA8350 Demo and Evaluation Kit
Introduction
This user's guide describes the use of the ATA8350 Demo and Evaluation kit for the ATA8350 Ultra-Wideband (UWB) transceiver device. This kit includes at least two different UWB nodes, each using a SAM Cortex®-M0 MCU to control the ATA8350 device. The Prover and Verifier nodes are set up as follows:
- Prover node – Must start before the Verifier node, and responds with a telegram once the verifier telegram is received. The measurement cycle finishes when the verifier receives the response telegram or when a timeout occurs.
- Verifier node – Shows the distance measurement data for distance-bounding measurements (single shot measurement) or localization (averaged measurement).
Demo software for distance measurements and data telegram transfer is available for this demo kit. In addition, this kit has an evaluation and a test software package.
The ATA8350 Demo and Evaluation kit comes in two variants:
- Variant A – Comes with one Prover node
- Variant B – Comes with a maximum of five Prover nodes
It also includes software applications for demo, testing and evaluation.

Figure 2-2. Demo Kit – Variant B
2.3 ATA8350 Demo Kit Components
The ATAUWB-EK1 board allows an addition to supply the board with 12V instead of 5V from the USB connection. With jumper J8, the 5V supply can be selected from the 12V DC/DC converter or from the 5V USB connector. The connector J1 provides the connections for the CAN and LIN drivers. For the CAN driver, the load resistors R15 and R18 are mounted and must be removed when they are not used as an end node of the CAN network.
The following figure shows details about the connector and buttons of the demo boards. The shutdown button is used to stop the application of the node and to power-down the ATA8350 UWB device. It is recommended the application be shut down before switching off the power supply. The reset button restarts the software application. The following figure explains how to mount the SMA antenna, and how to connect the USB cable.
The Verifier node has an additional jumper J4 to select the distance measurement mode, as described in 3.1 Demo VRPR Software Application.
Figure 2-3. Demo Kit – Details
3. ATA8350 Demo Kit – Software Application
The Demo and Evaluation Kit variant A uses ATSAMC21-XPRO boards with an embedded debugger and a USB COM port. This USB COM port is used in software applications to stream measurement data and for laboratory testing purposes together with a PC terminal application software.
The demo kit variant B uses an ATSAMC21-XPRO board with an embedded debugger and USB COM port and the ATAUWB-EK1 board with SAMC21 MCU and CAN/LIN connectivity. It is supplied either by 12V or by 5V using the USB port. This board is intended for testing in car environments.
The demo software application uses a layer architecture for easy porting between different MCUs. The adaptation to a specific MCU is supported with different Hardware Abstraction Layer (HAL) functions, specific for the MCU and its peripherals. For more details, refer to the Impulse-Radio Ultra-Wideband (IR-UWB) Transceiver User's Guide (DS50003127A).
The ATA8350_VRPR_Demo.zip folder has the following folder structure and files after unpacking:
- Application_Notes\ includes application notes and demo user guide
- Documentation\ includes ATA8350 documentation
- Hardware\ includes documentation for the ATA8350 Xplained Pro Extension board, the ATA8350-EB1 module and the ATAUWB-EK1 module
- Software\ includes application software for: ATA8350 demo for demo kit variant A (Microchip Studio 7 project including source code), ATA8350 demo for demo kit for variant B (Microchip Studio 7 project including source code), ATA8350 test software - ATA8350 evaluation software
Note: To program the SAMC21 devices, Microchip Studio 7 is required; it can be downloaded from www.microchip.com/.
3.1 Demo VRPR Software Application
The demo software application uses a separate software project and implementation for the Verifier node and the Prover node. These two software projects differ only at the application level and use the same driver for the UWB device and MCU peripherals. The verifier software controls the ATOLED1 display, and the UWB device operation initiates the distance measurement and performs the result calculation and display. The prover software initializes the UWB device in the Prover node and responds to the incoming verifier data telegrams. The following figure shows the measurement result on the ATOLED1 for the distance between the nodes in cm, the number of lost data packets since the start of the application and the clock offset between the Verifier node and the Prover node in ppm. The default mode is the VRo and PRo mode at the default channel A, which is 6.52 GHz.
Figure 3-1. ATOLED1 Measurement Data
In addition, a graphical view shows the leading edge position (small bar) and the position of the pulse maximum (larger bar). The position of the two bars gives an indication about the multipath reflections of the RF path between the Verifier and Prover nodes. If both bars are close together, a strong first path is detected (which might be a direct path or a multipath).
The measurement accuracy of ±45 cm is for one single measurement and can be improved by averaging, in other words, when performing measurements at different frequencies or at the same frequency or by evaluating
the le_shift parameter at the Prover and the Verifier node. This is useful in localization applications where a higher accuracy is required. Performing averaging with several measurements improves accuracy but requires more measurement time and power consumption.
The clock offset measurement is required to compensate for clock differences between the Verifier and Prover nodes, which may result in distance errors of up to 300 cm if not compensated.
To evaluate this behavior, the kit may operate in two different distance measurement modes:
- Distance-Bounding mode: The distance measurements are performed as single measurements, in other words, the distance differences up to ±45 cm are observed between each measurement, but with optimal power consumption and measurement time.
- Localization mode: The distance is an average value of 10 measurements, yielding measurement precision within ± 10 cm, but with higher power consumption and measurement time.
After restarting the Verifier node, the selected mode displays on the start-up screen on the ATOLED1. The Prover node is not modified.
The software projects for the demo application are available with the following directory structure:
• Demo Kit – Variant A:
- Demo_Kit/SAMC21-XPRO/UWB_Demo7_VRPR/UWB_Demo7_Verifier.cpro
- Demo_Kit/SAMC21-XPRO/UWB_Demo7_VRPR/UWB_Demo7_Prover1.cpro

3.2 Demo TXRX Software Application
The demo software application uses a separate software project and implementation for the Transmitter node and the Receiver node. These two projects differ only at the application level; they use the same driver for the UWB device and MCU peripherals. The transmitter software controls the ATOLED1 display and the UWB device operation and initiates the data transfer and performs the display of the received response. The receiver software initializes the UWB device in the Receiver node and responds to the incoming transmitter data telegrams. The following figure shows the data transfer result on the ATOLED1 for the number of lost packets since the application started and the clock offset between the transmitter node and the receiver node for the last transfer.
Figure 3-2. ATOLED1 Transmitted Data
3.3 Evaluation Software Application
The evaluation software application is available for the ATSAMC21-XPRO boards. This software application uses the USB COM port with a menu (shown in the following figure) to control the application. This requires a typical PC terminal application, which can be connected to the USB COM port using the following settings:
- Baud rate: 115200, 8 data bits, 1 stop bit, no parity, no flow control
