As I can see ATM128 is not powered, at least I don't have 3,3V between pin 1 and 2 (in fact, there is no voltage)
Here is how pin are connected now:
- to battery -
- EC36-pin5
- EC36-pin21
- EC36-pin26
- EC36-pin32
- connected to battery +
- EC36-pin25
I'm not sure I have the good pin layout as I'm using the v3.1 board. Could someone confirm that? (especially for the EC36, as I don't have any power on the atmel processor).
Q. I would really appreciate to know if I'm right with the battery + connected to EC36-pin25. As I can see, this pin doesn't go further on the board. I mean, there is no track from where I soldered the cable.
A. Yes, battery + (12V) should be connected to EC36-pin25, but see also the following link to see how to mount the power on board..Hans .. http://vems.hu/www.vems.co.uk/VEMS/ConnectingPower.html
Thanks a lot, I'll try this. Bus as I can see on the picture on the page from phattransmission, my board has not the same components. Of the inductor between 1 and 2 and the fuse link between A and B are missing, but other components are not on my board. Do I have more components than the 2 to solder? (I'm not talking about coil/injector drivers)
The inductor from Rescue kit1 marked 1R5 must be soldered Between A&B, and just a wire (short) betwen 1 and 2 if a fuse is mounted external. The inline diode and the voltageregulator (top-left corner of first pic) should bee mounted when you got the board. I think that is it, hope it helps. Hans
using information from Hans (thanks again), I was able to get power to the atmel.
- I can measure 4.5V between pin 1 and 2 of the atmel processor
- that's a bit low
- In fact this 4,95V, I simply forgot one number...
- what is supply voltage and current at the 12V supply ?
- It is 11,78V
- that's a bit low
- voltage regulator is heating.
Battery is ok
