Problems with axe 08m and l293n
September 25, 2011
I have a teeny problem - I'm playing with stepper motors for my next robot, the plan is to have an 18M2 sending serial packets to a pair of 08M2s which each will control one stepper, to save outputs on the 18.
My problem is this, when I have the 18 running into the L293 driver the motor runs perfectly, but when I use an 08 nothing happens and it gets hot (I fear the magic smoke)...
As far as a setup goes, I've coils 1,2,3,4 running (via the L293) from outs 0,1,2,4 on the chip in that order, both Vccs and the picaxe running from the same 5v supply, a unipolar stepper motor, I think that's everything...
Here's a photo of the board in the state it is when things get hot:
Any and all help gratefully recieved :)
