    Hi again, I have 40x2 3V and would I use it with LCD117 Serial LCD from modern device. That lcd works with 5v and picaxe 3.3v. So would I send data to that lcd? Would it work? Or should both be 5v-versions? Thanks, Jani

    X2 3V download cable

    I'll tried search. There is notice that I have to use AXE027 cable on X2 3V-version piacaxes. But is it safe to use usb-serial-adapter for downloading (USB010)? I have that adapter now.

    Interfacing sensor problem

    I have a pressure sensor, VDO-style. The ohms are 1.5 to ~160 ohm and 0-150 psi range. How I connect that to 40X1? I had read voltage dividers topics, but I don't understand that how big resistor should be. The supply voltage would be +5V and the sensor end is in ground and one signal wire.
