I too have just received the Hijack unit and cannot get it to work with my iPad2 nor iPhone4. I have tried the Hijack oscilloscope app and techBasic. The oscilloscope only gives random readings and doesnt even progress horizontally with a smooth speed. With Hijack.bas I get largely no reading but occassionally a horizontal reading just above 150.
I have the volumes on both devices set to full and have reprogrammed using with the USB adaptor just in case. The reprogramming works. I have also measured a voltage of 1.5V accross the Hijack GND and VCC pins when the code is running. This drops when I connect a 10K resistor across the supply rails. I have tried shorting the analogue sense pin to GND then VCC but still either get no reading or random waveforms, depending on the application used.
Should I be sending these units back for a refund or is there something that can be done.
