About …”Xhorse EEPROM Clip Adapter for VVDI PROG
Depends on PCB whether need to use PROBE !
1. What PCB need to use probe ?
2. There are two wire to probe (red & brown). Do I use both of this or one ?

Explanation:

  1. If you cannot read with clip alone then you need to use PROBE wires.
  2. Both. One to GND other to PCB’s MCU’s XTAL pin if there is one.

Question:

Both wires have mark “GND” !! I made picture 1.
On my picture 2 – one of “GND” (brown) I connect to probe and…to PCB’s MCU’s XTAL pin if there is one.
Another wire “GND” (red) – where ??

Answer:

Professional solution:

Second wire to GND!!! ALL PCB’s have GND.

Question:

Ops ! We connect PCB-s GND with “MCU’s XTAL pin” through probe !! is it correct ? Like picture ?

Answer:

Yes and also the programmers adapter!

BTW, I not need use connected any other wires then clip only…and work very well….24c02, c04,c16, 5P08 and others…
