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?
