my problem is the microcontroller does not operate and I do not know the problem and tried to make 12f675 drive a led high but did not operate also. I want to know the solution. Thanks

driver circuit for stepper motor with 12f675
Hello, first try to find the correct programmer. Internal oscillator of 12F675 starts to run during programming and this stops programming.For this Vpp must be applied before Vdd. This puts the IC in proggramming mode before Vdd applied.I have found a good programmer at the site Ham Radio India. I tested it and it worked.
For 16F84A and 16F877 there is no such problem because they don't have internal oscillators.
Also carefully check the ports and registers from the data sheet.
Good Luck.
