I have problem interfacing BS2px24 with LM629 for 2 weeks.
1) Does LM629 actually accepts TTL or must it be CMOS or other logic levels?
Is there a logic level mismatch between BS2px24 and LM629?
2) Is the clock a must for proper operation? The BS2px24 does not have a pins which can output a clock. Does connecting an external clocks help?
3) I could not get a proper response after set low to PS, CS and RD. I used a direct connection from the stamp pins to the LM629 pins.
Is it not possible to build something out from BS2px24 and LM629 together?
Can someone shed some light on me?
Thanks in advance
