PIC18F452 and DC motor controller.
March 15, 2009
Becausse the PICAXE kit already ships with all the components (er, most of it) glued, I wanted something more challenging. So, I am trying to build my robotic brains from scratch.
Whilst I have come across quite a few (video) tutorials with circuit diagrams using PIC microcontrollers, I am not able to use a motor controller. One such is here: http://www.seattlerobotics.org/encoder/200001/simplemotor.htm.
As advised in the circuit, I use SN754410 to drive my motor. But, my simulations with ISIS7 isnt working. Could someone tell me what I could be doing wrong?
In my attempt to solve the problem, I googled away and learnt about the PWM way of controlling the motor. Circuits posted there are also failing my simultations with ISIS7.
At the moment, since I am not sure about the components (becasue I am still simulating) I havent bought the hardware.
Any advise, links appreciated.
