Core No Voltage @ IC1:Vdd(32) - IC1:Vss(31) = 5V

Hey I have assembled my core board (SmashTV) and am not getting the 5V at IC1:Vdd(32) - IC1:Vss(31) = 5V… The other pins are getting the req’d 5V… When I trace those pins I find that that pin IC1:Vss(31) connects to J15 pin “E” and IC1:Vdd(32) connects to J15 pin “RW”… Upon looking at this it would seem that there will only be a voltage present with the chip installed cos uninstalled it looks like an open thus no 5V…

Is this correct to assume?

Count the pins the right way and it’ll all work out. You measured pins 29+30. Major déjà vu:

I did the exact same thing when I built mine at first. Its because if you go from the image on the contruction guide the dots that indicate where those pins are is in the wrong place, when I counted out the pins I found the right ones and 5v popped on screen.

Which construction guide are you speaking of for future reference

Is it the one on the Ucapps Core module page?

Hehe its good to find out about easily made mistakes like this in advance.  :slight_smile:

Is that some sad attempt of a joke?  :stuck_out_tongue:

Edit: Spotted something mentioned about midibox, but didnt find the guide so maybe not! LOL
