Is there any brother who has done hooking in evc? I downloaded the example and studied it for a long time, but I still can't figure it out. I used the source code to modify it and made a dll. It can b...
There are two main issues here:
1) How are the 2Ω of R150 and the 300Ω of R151 calculated? Or is it an empirical value? Is the 300Ω just used for current limiting of the voltage regulator BZX84-B13?
2...
