Problem interfacing ADC

[moses]

Hi... actually i tried to interface ADC AD7842KN... after connecting all wire... i tured the nmix-0332 on... then... on the screen... somehow only max-forth debugger poped up... actually i removed the resistance since i use only cpu32 debugger.... and i can not get onto the cpu32 debugger.... do you know what the problem is ???

With the resistor R9 removed and Max-FORTH is still running, it sounds to me the data line, D3 is driven hard by the peripheral, AD7842KN. Maybe your connection is not correct. If you don't intend to use Max-FORTH, email me nmitech@newmicros.com I will email you the Srecord of the BUG32 monitor, so you can burn a new set of eproms and it will ignore the D3 condition on power up so you can run the Bug32 Monitor alone.
