Hi, I just soldered together my yadro finally, and installed dos on a old dead laptop.
I connected to the int4 interface fine, see the "welcome to yadro land" etc, and do a v for version number.
Then I connected it up to a cheap vernier caliper I had for the purposes.
However when I did a da or d0, the first (and only) scale reports :-
Checking device #0...
Clock : Signal
Data : Signal
And thats it. No Device: entry. If I repeat the tests about 5 or 6 times I get the error "Device: unknown type" added to the end. The int4 hasn't locked up as it will do a v or a d0 straight away, it just isn't reporting back the status from interrogating the scale.
I tried flipping data and clock lines, and its made no difference. If I pull either of them to gnd, I get a error saying they have gone L, and disconnect them and the int4 reports theyre H for high (open circuit).
With a DA, the rest of the scales report Clock and Data as H, without a noticeable delay.
Is this just the scale not compatible with yadro? New protocol? Or something amiss with the int4 in some way? It looks like the same pcb as on the yadro site but the voltage and gnd lines on the connector are in different positions too (I connected directly to the battery pads instead).
I can order some of allendale's replacement caliper heads if its a protocol error because I've read on the net that their caliper heads work, this is just a cheapie I picked up at the local diy chain.
