# SDC-ACQ_DAC 板卡测试上位机
发布程序位于 `output/pc-test/SDC-ACQ_DAC-TestTool.exe`，目标为 Windows x86 和 ZLG USBCAN-II。
## 使用前准备
1. 将匹配的 ZLG x86 运行时复制到程序目录：`ControlCAN.dll`，以及 `kerneldlls/usbcan.dll` 和 `kerneldlls/kerneldll.ini`。
2. 将 USB-CAN 与板卡 CAN1 或 CAN2 接在同一条 500 kbit/s 总线上，确认 CANH、CANL 和公共地正确连接。
3. 关闭其他占用同一 USB-CAN 的软件后，启动程序，选择设备索引与 CAN 通道并点击“连接”。
## 测试能力
- 显示并记录 `0x6A0` 至 `0x6A6` 的实时报文；解码心跳、电压、轮速、GPIO 和 DAC 应答。
- DAC1/DAC2 一次发送，或每 50 ms 持续发送。持续发送用于满足板卡每路 100 ms 的 DAC CAN 超时要求；停止后板卡将自行归零。
- 一键发送 5 种 ASSI RGB 状态，以及标准帧手工发送。
CAN 适配器以正常模式打开，因此会为板卡的 CAN 上报帧提供 ACK。

- `kerneldlls\\usbcan.dll`
- `kerneldlls\\kerneldll.ini`
Do not run another CAN application against the same adapter at the same time.
