hi masters..
i got a project with this: 12v 5a actuator to be control by a PIC16f877a..
the actuator works like a motor..when i apply 12v source to it..it pushes and when i invert the source it moves backward..
so it works like a punching arm..
i got an h bridge circuit between the PIC and...
oh i got the problem or in our language..the problema!
i bought new PIC and it got worked.
thanks to you all of my masters and for the ideas..
i dont know why my old 877a is deffective in a way that it s readable and programmable but nevermind..i got my project working!
1. how to reduce clock pulses?
my clock frequencly wd my program is 4mHz and i used 4mHz xtal wd the 877a.
2. scope? im workn at home and i got no scope..
3. connections are checked..many times..
4. code? it is correct when i simulate it in the PIC Simulator
hi masters..
b4 i got a program with a pic16f628a with a 4x20 LCD and it did work..
but when i switch to an pic16f877a..all i have are dark squares..
my program is in pic basic..
changes i added wd the pic includes having a 4mHz xtal, pull up resistor in MCLR to +5v and nothn more..
now..i ask...
hi newbie here..
i need to control an actuator with a PIC16F628A and the program should be in PICBASIC..
but i need a circuit between the PIC and the motor of the actuator..
the actuator's motor is clockwise and then counterclockwise..
can any1 help.
:cry:
tnx for the sharing mr FvM..
actually i am a novice here about those kinds of motor..
it is from a printer motor..the one that rolls the paper..
it rotates by step..so it must be a bipolar stepper motor..
the problem is it has 4 leads and when i search some circuits on the internet..
i got...
can anyone help me..i got 12 days to make my machine.
the machine involves driving a bipolar motor of a printer.
the problem is i need to drive the motor is such a way that it feeds in and feeds out the paper in the printer.. like the maintenance part of a printer..rolling out of paper.
pls...
