ThanX A LOT stryd_one and piletaylor......Problem is finally resolved............d Cable was too long.... I cut it short ....about one third d original length and voila it was working!!!....thanx a lot again.... cheers Sandy

I changed the timings and it was working........yup its a borderline case.....almost complete......my printer cable is old and a little too long....could this b a problem?...but it is recognizing the PIC type....ne help wud b greatly appreciated!

Well, I managed to get my PIC burner to work........but now it gives too many program ERRORS.. -------------------------------------------------------------------------------------------------- PIC-Typ PIC18F4550 Rev. 5 detected CP-Blocksize : 2000 Panelgröße : 0000 -- HEX-file re-loaded -- HEX-file contains Config-data Chip erased 1 Panel(e) Start write to PROGRAM-Memory --finished Start write ID --finished compare PROGRAM, ID and EEPROM : -->6325 errors in PROGRAM -->0 errors in ID -->0 errors in EEPROM Start write Configuration --finished compare CONFIG : -->6 errors in CONFIG ----------------------------------------------------------------------------------------------------------- Wat to do now gurus??

I guess having an older Desktop gives a upper hand in burning PICs ;) 8) OK I'll try a new cable then By the way Im using a DC adapter 15V,500mA.....could this be a problem? ??? Sandy

I tried the burner on my laptop but the P18 refused to detect a programmer I dont know how to change modes. Its not mentioned in the "testing" section but in the photograph you can clearly see that the multimeter reading without the HC11s. Yes, Its working the way it should. I tried at the slowest setting but It shows an output at this setting only ??? I didnt try that....but i think that cable is not a problem

Ya...This 'could' be the case....I only bought one of these PIC ( very costly!! comparatively )....I'll try my friend's 18F PIC or buy a 16F series PIC..... Any more Ideas are more than welcomed

By the way it does recognize a PIC but the ID is not correct (I changed the Timing ) ---------------------------------------------------------------------------------- Timing: Interface x16 / PIC x3 ## this PIC-ID 0x0000 is not in database CP-Blocksize : 4000 Panelgröße : 0000 ----------------------------------------------------------------------------------- I think 0x0000 means Nothing ??? :-[

1)Yes, it is MBHP_Burner frm this link: http://www.ucapps.de/mbhp_burner.html I am trying to burn the USB bootloader in the PIC through this burner 2) Yes, without the 2 ICs (74HC14) the programming voltage is 12.46V (through LM317) and 5.1V (through LM7805) ???

Hi Everybody, I made this burner and it is passing all the tests i.e. Vpp,Vdd,CLOCK,DATA,DATAin,.....but the Software P18 is not recognizing the PIC(but it shows that the programmer is detected at LPT1) ???! the PIC no. is PIC18F4550....can anyone Please Help me! Thanx in Advance Sandy :)
