Fusion digital power designer 使用时找不到设备(ucd3138)

Other Parts Discussed in Thread: UCD3138我用ucd3138搭了一个三环路的电源,两路硬开关全桥一路双端正激。 把ucd3138的9脚(时钟)接到了适配器的9脚 芯片的10脚(数据)接到了适配器的10脚 地线接到了适配器的6脚 测量芯片的复位端有5v电压,3.3A,3.3D都有电,但是GUI一直显示找不到设备。 不知道为啥 用的不是JTAG口的话也有阻抗匹配的要求么? 我的连线不等长 适配器型号:USB转i2c/gpio适配器 usb interface adapter
