Supporting Evaluation Tools
The ET-UARTSWD adapter is the preferred adapter for evaluation of PAC devices/firmware and combines a USB to UART adapter with SWD debugger connector adaptation into a single board with isolation. The ET-UARTISO-1 adapter provides only the USB to UART adapter with isolation for Qorvo application GUI communications.
ET-UARTSWD公司
The ET-UARTSWD isolated communications and debugging interface unifies two modules into one. Previously, interfacing a PC Computer to any of Qorvo's PAC5xxx Evaluation Modules required one module to enable UART based serial communications and a second module to allow for in-system debugging and FLASH memory programing.
ET-UARTISO-1型
The ET-UARTISO-1 adapter is a USB to UART adapter for Qorvo application GUI communications with the PAC device UART, and can be used for evaluation and debugging of PAC applications.
PAC5xxx闪存编程工具
Qorvo与闪存编程解决方案提供商合作，支持我们的智能电机控制PAC产品系列。这些经验证的工具适用于新兴和大批量产品制造。包级（插接）和板级闪存编程解决方案都可用。
Qorvo将支持熟悉Arm®串行线调试（SWD）协议的其他供应商在其现有的Flash程序员平台上添加PAC产品兼容性。详情请联系Qorvo销售。
PAC52xx软件
| PAC52xx BLDC应用程序固件 版本：v2.3.0 |
Installer for the PAC52xx BLDC application firmware, which implements sensored BLDC and sensorless BEMF motor control on all members of the PAC52xx family. The installer contains example application source code, Windows graphical user interface (GUI), and documentation to allow the user to configure the system to work with their target motor. Project files for IAR Systems Embedded Workbench for Arm (EWARM) and Keil uVision are included. |
| PAC FOC应用程序固件 版本：v4.3 |
Installer for the PAC FOC application firmware designed to show case motor control using sensorless Field Oriented Control (FOC) on all PAC devices.
