Hi,
im going to make an energy meter using ADE7756 with AT90S8515 microcontroller. i have a big problem in the /irq pin of 7756. i am trying to read waveform samples however the /irq pin does not go active low. i set the update rate in the mode register, then enable the WSMP in the interrupt register. i connected /irq pin to a negatively edged triggered interrupt pin (pull up resistor enable). i've been working on this problem for almost 2 weeks. somebody please help me. tnx.
