PGA900开发遇到问题,求大神帮助

Other Parts Discussed in Thread: USB2ANY, PGA900

PGA900GUI USER‘GUI DE 的第28页激活OWI有这么一段话

For OWI Activation
• Through I2C:
– The digital interface is enabled by writing 3 to MICRO_INTERFACE_CONTROL.
– The I2C communication parameters (speed, address length, and pullup speed) are set.
– The 3.3-V and 5.0-V power outputs are enabled.
– GPIO_OWI_ACT is set to LOW.
– GPIO_OWI_TX is set to HIGH.

但是如何设置GPIO_OWI_ACT 和GPIO_OWI_TX,是在评估板强行拉高/拉低?应该怎么操作?

  • GPIO_OWI_ACT 和GPIO_OWI_TX

    没有玩过这个评估板

    评估板上的两个信号, 看看有没有简单巧妙的办法, 不破坏评估板设置这个信号.

  • 一楼的工程师你好!

    1. 现有评估板上控制OWI激活,是通过外接的USB2ANY板实现的。你处提到的连两个管脚与USB2ANY对应控制线相连接口实现。

    2. OWI激活电平要求以及时间要求,请查收手册中描述。

    3.OWI的通信需要软件支持,PGA900收到有效OWI激活命令后可以进入到对应的服务入口
