I Mr. Ezo I do really appreciate the useful info that you place on the site that helped me a lot, now after like 3 years of use of my programmer version 4.4, i need to replace it ,because due the hard use and the poor building of my pcb skills finally died ( i mean need a new one). But the programme...

Hi Mr.Ezo first of all I want to apologize for making you work extra time for my mistakes._You was right and I was wrong (feel silly about it).As you mention in your guide the Lpt cable is 1to 1,my mistake was i wired from 1 to 13 (12 and 13 are useless),then i wired from 15 to 25 and left pin14 unc...

Tnx for answer Mr.Ezo ok I isolated BU1/14 from pcb and checked OE-24 and no changes,but I want to mention I have 5v on BU1/14 isolated and I have 5V on the other side, the one which is connected to pcb that goes to IC5/14 and R15 10K. Let me tell you if i pull out R15 10K i have always 5V on BU3/12...

Mr.Ezo i checked BU1/14 R15 was opened now I have these readings A22 to a18-31 are ok now CE-22 to A11-25 are ok now A10-23 BU3/11 is ok now too but OE-24 is not switching the 5V are not longer in BU3/12 now is 0V IC7/10 0V,IC5/13 5V no switching at all ,BU1/14 5V no switching too OE D7-21 to 13-DO ...

Mr.Ezo I continue checking the programer i found these readings Vcc32 1Vpp 12.15 3.7v ok A22 to A19 no changes 0v 12-A0 to A18-31 no changes 0v Vcc32 Bu3/20 5V 0V ok CE-22 5V 0V ok A17-30 to A11-25 0V no changes at all 0E-24 no changes i have 5V all the time no switching IC7/10 5V all the time IC5/1...

Mr.Ezo i was testing the programmer sw).97ja Jp1,jp2,jp3 (5vmode) Vcc32 1vpp Bu4/37 12.15v 3.7v red nad yellow Led A22 BU4/36 no change 12-0A to A18-31 no changes Vcc32 BU3/20 ok 5v 0v an all others dont work but I got a weird reading on BU3/12 i have 4 v all the time no switch or some I rechecked a...

Ok Mr. Ezo now I am running SW version 0.97ja select chip AT49F001 set jumper JP2(+3.6V), Jp4 Check valid get ID reply 0x1F Atmel, 0x05 AT49F001(N) I got this reading: Manufacture 0x00 [....] Device code 0x11 Nothing (clear) The programmer seems to read ok and gives me that message screenshot1.PNG S...

Hi Mr.Ezo now I'm asking for your help to read and write Flash AT49LV001N , I built the ezoflash version 4.4,the software recognize the programer but i cant set the software, I checked the chip database and 3.3V tsop 32D adapter,but dunno how to configurate the software ,i cant find the AT49LV001N,o...

Hi again Mr.Ezo " Btw what is exact your IC2 chip type , 74LS06 or different ? " ok ,the IC2 chip that i'm using is SN7406 ,its from a fake brand dunno if meets all the specification but now works. I read and write differents 25128-25256-25512 already ,I havent tried with 24CXXX but I guess its gonn...

Yeahhhhhhhhhhhhhh succed many thanks Mr.Ezo the changes made the difference : Replace R12 22k to 2.2k and R13 2K to 100 now IC2/8 (0/5) ,and software "Hardware Present" every thing you pointed was right ,so its means the schematic must be corrected to those changes right. Now just have question abou...

Ok Mr.Ezo I check again and these are the results: See schematic. D0 is running from D00 (BU1/2) through 4 logic elements back to BU1/11. Now changes stops at IC2/8 . Last checked controlpoint IC2/10. Run same test and check again IC2/10 (5/0), IC2/9 (5/0), IC2/8 (0/5), IC2/3 (0/5), IC2/4 (5/0), BU1...

Tnx for anwser Mr.Ezo I checked all the info you posted and those are the results: 1) check used LPT port (LPT1) Ok 2) check parallel port cable (extension 1:1) Ok 3) go in SW Test H/W (frame in SW below), set Jp1, Jp3 (5V) Ok a) activate 32-Vcc , it should turn green LED on having a multimeter and ...

imagen arreglada1.jpg Hi Mr.Ezo i built the ezoser programer ,i finished but when i tried to use it the red led stays on ,i followed the sequence : Connect LPT cable to PC and programmer. Run Willem software. Connect power supply to programmer.red led stays on (no flash just steady) Run Willem SW c...
