I use FPGA to configure ADV7181B via I2C, but ADV7181B has no ACK. Its power supply and reset are normal. What is the possible cause? How can I confirm whether it is burned? I had ACK before....
I am going to reload the CButton class and implement a self-drawn CheckBox, which is to use two pictures instead of the system box. Now I find a problem, that is, when I click the CheckBox and then re...
Why is the loop unity gain bandwidth of the DCDC a fraction of the switching frequency? Why can't it be several times? Wouldn't it be faster this way? Please help me, experts...
