    hi,

    i was curious with your idea letting a 555 be a ramp generator, and have look at the innards of the 555 it it is really possible. maybe my knowledge with the inner working of the 555 might be lacking, but i can't seem to imagine how a totem pole transistor configuration can be made to do such. maybe i'm wrong?

    why not use rather a dual supply quad op-amp to produce the wave you want. 1st op-amp to produce the positive ramp, the 2nd to produce the negative ramp and the 3rd to come up with a square wave.

    where are gonna use it, are you try to making a transistor curve tracer?
