Created and assembled board, connected to ST Link V2

[Mmma2345]

Hi @dekuNukem,

so, firstly a massive thanks for the project; this is exactly what I’m looking for !

I’m also a beginner in electronics. But am a very quick learner. Before starting this I have done research and practiced using various boards etc. so I believe my soldering job is half decent.

I’ve had the boards printed (Exixe-14) I’ve assembled 1 board so far using the BOM provided and attached a working (and tested) IN-14 Nixie Tube.

I’ve soldered pins to pads : 3.3v GND DIO CLK

from here I’ve attached the four pins via jumper wires to a ST LINK V2 as suggested. With the suggested software.

I click the button to link to the STM32 via the software but an error appears showing : no st link found ( I’m writing this from memory so will double check the wording of this when next at the pc! )

I also checked the voltage across the GND and 3.3v pins when connected to the ST LINK V2 with a multimeter; this only showed around 0.1volts. but once disconnected the ST LINK V2 showed 3,3volts again. Seems odd ?

Any helps would be great!!
