Testing Assembly without Stimulator

Post by dan.tolan »

I am finally putting my MS(1) V2.2 board together and I am trying to test it. I think I have an issue with my Stimulator V2 board.

I was able to test the power supply by checking the pin-outs (1-2,...) and they all read correct (5v) and I was able to test my serial interface as well -
Testing this was done by putting power to pin28 and ground on pin1.
When I plug in my Stim - I get no power readings on the pins. - So for now I am leaving it (the Stim) alone.

I am at step #35 - Testing the operation of the processor.
Is there anyway to test it without the Stim ?
I know I will need to get the Stim working but would like to continue to work on building the MS(1) to get it completed this week if possible.

Thanks for any help

You are not the "Lone Ranger" as far as getting excited and wanting it all done now! I had the same problem.You need to follow the steps carefully as they are critical. The senior members have things outlined well, and the assembly guide says "fix the stim! before proceeding further". Haste, in this case, will make some high dollar waste.

Thanks, Figured out that it was the confused person behind the soldering iron - I had actually installed the DB37 (and DB9) connector on the wrong side of the board (Step #2 on the installation) - Desoldering tool in hand - got it fixed and assembled the board without any additional issues.

I have run the Stimulator for about 24hours now and everything appears good to go.

This is going to be a fun winter project
