德国EMS Dr. Thomas 公司can卡CPC-USB/ARM7-GTI
CPC-USB/ARM7 是一个用于 USB 端口的 CAN 接口,采用紧凑而坚固的金属外壳。由于易于操作和优惠的价格,CPC-USB/ARM7 适用于 CAN 系统的配置和分析。 CPC-USB/ARM7 配备 Cortex M3 微控制器,提供片上 CAN 和 USB 控制器。通过将强大的 CPU 与内部外围设备相结合,可以实现低延迟。该接口完全通过 USB 供电,无需为 CAN 侧单独供电。它支持 11 位和 29 位标识符。该接口可选用电隔离。此外,还提供带有低速收发器 TJA1054A 的变体。对于无法避免 CAN 总线端子上出现较高故障电压的应用,可以使用 HV 版本。收发器 MAX13052 的使用允许 CAN 总线上的电压高达 ±80 V。还提供带有 RJ45 CAN 连接器的版本。对于 Windows 和 Linux 操作系统,具有相同 API 的软件开发工具包是免费提供的。支持 SocketCAN。
Description
CPC-USB/FD is a CAN FD interface for USB ports in a compact and robust metal housing. Due to easy handling and favorable price CPC-USB/FD is suitable for configuration and analysis of CAN FD systems.
CPC-USB/FD is equipped with a Cortex M4 microcontroller providing onChip CAN FD and USB controller. By combining the powerful CPU with internal peripherals low latencies can be achieved. This is supported by the high speed USB connection. The interface is powered via USB, a separate supply for the CAN side is not needed.
The interface includes galvanic ***lation. The used CAN FD transceiver tolerates DC fault voltages up to ±70 V on the CAN bus lines.
For the operating systems Windows and Linux software development kits with identical API are available free of charge. SocketCAN is supported, the driver is executable with existing application software of the CPC-USB/ARM7 V2.0.
