So the only thing I do not remember is control, I know I tried both options (high and low) cw/ccw - same as half/full - tie to high or low, do not let float half/full - whatever you like but you have to tie it high/low, do not let it float control - this one is important but I don't remember if it should be high or low, but you have to connect it high or low, check both options you cannot kill anything sync left floating (not connected to anything) not used RS1, RS2 (tied 1,15 of 298 and 13,15 of 297 to gnd - but you should use RS1,RS2 0.5R) I have not used the 297 298 combo for stepper for some time now but from what I remember I doubt anyone can help me since I don't even know what to write, but I need to vent!!!!!ĮDIT: Damn, my 1000th post is about my defeat! Talk about insult to injury. The L298 in that "multiwatt" package dosn't fit in protoboard very well and its alot harder to tell the pins apart then the DIP package ICs.ĪAAARRRRGGGGGGGGGGG. Its really kind of a mess to try on protoboard. I have pulled all the wires out and redone it several times figuring I wired somthing wrong. I really don't know what else to say or try. I have an LED on it so I know that part is working. I have ENABLE and VREF pulled high and CONTROL pulled low.ĬLOCK is hooked to a 555 timer running very slow. 2 on page 8 of the 297 datasheet.Įxcept I don't have the OSC, SENSE or INH pins used. I don't think I have killed it with reverse polarity or anything. Is there anyone here real familiar with the 297/298? I have spent 3 hours trying to get it to work on protoboard.
