Total Phase推出一种低成本分析仪,可以非侵入地监视高速I2C (4MHz)spi (24MHz)。嵌入式系统工程师利用Beagle I2C/SPI协定分析仪可实时监视总线活动情况,分析率达20ns

Beagle I2C/SPI协议分析仪特别适合嵌入式系统工程师,是Aardvark I2C/SPI主机配接器的完美补充。Beagle分析仪给现场应用工程师带来的最大好处是占位面积小,便于现场除错。由于Beagle分析仪从USB取电,因此不需要电源配接器。只需将Beagle分析仪插入高速USB 2.0埠即可使用。

此一协议分析仪的无版税API适合自动测试环境。测试夹具可使用Beagle API以充分利用Beagle分析仪的全部特色,是适合生产线的快速有效的方案。该款协议分析仪提供完整的分析软件和免版税API,没有额外的支持合约和软件升级费用。

The AardvarkTM I2C/SPI Host Adapter is a fast and powerful I2C bus and SPI bus host adapter through USB. It allows a developer to interface a Linux or Windows PC to a downstream embedded system environment and transfer serial messages using the I2C and SPI protocols.

Detailed technical information about the Aardvark I2C/SPI Host Adapter can be found in the Technical Specifications section of our web site and in the datasheet.
