Other Parts Discussed in Thread: DAC80502, , DAC80502-01EVM
After I unpacked DAC80508 EVM board, I directly used the USB cable sent with the circuit board to power up, the voltage is 5V, 3.3V, 1.8V, and the reference 2.5V, both have voltage, I downloaded the latest software matching the DAC80508 on the TI official website, after opening, connect green light, but whether it is switching the reference voltage or changing the output code, the 8 output ports are not responding, always 0V, the reference is always 2.5V, when the oscilloscope detection is found that the GUI sends instructions, there is no clock signal in the DUT_SCLK, and the judgment signal fails to be sent, I reinstalled the system, The system I use is always windows10 education version 64-bit, in a very rare time, the communication is successful, and it can be controlled normally, but after powering off and re-powering on, it can't be commanded through the GUI, and now it is in an unusable state, including DAC80502-01, I purchased two kinds of EVM and can't use it
