Hi All,
i used PIC microcontroller to control a stepper motor with support of TIP120 ....... on the same circuit i'm using a another PIC microcontroller to opearte GLCD and based on selections on this GLCD i send only one signal from the second microcontroller to the first one to start turining the stepper motor.
my problem is , when i opearte the circuit i found either the GLCD or the motor doesn't work or the circuit keep flashing . but if i disconnect the GLCD i found the stepper motor works well , the same when i reverse.
i guess the problem is with the power supply . i'm using 6 volt 3A power supply ... but it seem it's not enough .
is it possible for me to use 2 power supplies ? in this case the first micro will send a signal to the seond micro so do you think it will work ?
please advice
this is the link for the first micro controller circuit.

also attached the schematic for the first micro with the GLCD
Thanks
