[SOLVED] Pickit3 and 16F648A ?

[bianchi77]

Guys,

I have written into 16F648A using PICKit3, when it's connected to PICKit3 and MPLAB, the chip is running,
but when I plugged it out and put on normal power supply it's not running at all,

Any experiences or ideas will be very appreciated,
thanks

Hi,

Check that your MCLRE and OSC settings in the CONFIG code agree with the hardware you have used.

Hello there,

It may be a loose connection in power supply or Programming pins.. Just check your circuit fully, reset pin too.

Best regards,

I put 20Mhz crystal, reset pin internally connected to Vdd, Vpp is not connected when there's no PICKit3

It said "Programming complete " no error from MPLAB....
I don't understand....

Yesterday was fine and now it's not flashing...same chip same code...
