RE: DIY data logger on HP48GX and Invalid Card Data message
Yes, I have tried the PINIT command but it doesn't fix the problem. I wonder how the HP test the card on port 1. How the calculator knows what type of card it is, 32 or 128kB for instance? Does the calc actually reads the memory on the card at the init stage or is it a matter of setting the appropriate voltage on few pins of the card?
