2008-12-02T00:30:13-08:00Connecting to MPLAB ICD 2...ConnectedSetting Vdd source to MPLAB ICD 2Target Device PIC12F629 found, revision = Rev 0x10ICDWarn0044: Target has an invalid calibration memory value (0x3FFF). Continue?ICD0200: Operation Aborted (Warning 43).MPLAB ICD 2 Ready Having this problem when trying to program the piC12F629 !Help... i successfully programmed 1 of my same pic, but later on i used another pic, when i wan to program it it pops up """"ICDWarn0044: Target has an invalid calibration memory value (0x3FFF). Continue?"""""then i put back my another pic, its still the same although i tried it with my 1st pic which was successful, its now also have this warning...any help is very much appreaciated.Re: Help on ICDWarn0044: Target has an invalid calibration memory value (0x3FFF)

2008-12-02T00:30:13-08:00nicholastychi Ajay, i already have the most updated firmware. I did nothing wrong , and why when i trying to programme the chip its will pop up this warning!I am trying to program it for the LED dimmer i made the programme for...now wanted to test on it...but cant programme... =(Re: Help on ICDWarn0044: Target has an invalid calibration memory value (0x3FFF)

2008-12-02T00:30:13-08:00Ajaytry updating the firmware of ICD2.Re: Help on ICDWarn0044: Target has an invalid calibration memory value (0x3FFF)

2008-12-02T00:30:13-08:00AjayPIC12F629 is not supported by the ICD2. Also most of the 12-bit instruction targets are not supported by ICD2. So you are getting this error. try replacing it with some other 16F IC and see if problem presist.Re: Help on ICDWarn0044: Target has an invalid calibration memory value (0x3FFF)

2008-12-02T00:30:13-08:00nicholastyci will try to update you for the result later..if i got time! thanksRe: Help on ICDWarn0044: Target has an invalid calibration memory value (0x3FFF)

2008-12-02T00:30:13-08:00nicholastychi Ajay, i programmed my pic12f629 with pickit2 , but the programme doesnot work at all...i tried to make a simple blinking program..it still doesnot work...i will post the normal turn on led program, i simulated it in mplab sim, it does work to turn on the output!Re: Help on ICDWarn0044: Target has an invalid calibration memory value (0x3FFF)

2008-12-02T00:30:13-08:00nicholastychi Ajay, i am really scratching my head, i already programmed my code above to my pic...i tested my code on MPLAB SIM, it worked totally fine with what i expected.But it dont work after i programmed the code into pic...wat;s the problem with setting??????thanks!Re: Help on ICDWarn0044: Target has an invalid calibration memory value (0x3FFF)
