EZoFlash форум

I have ezoflash 4v4 and will modify to program PIC, could use some help to make the connection and set the software ezoflash in the PIC, the PIC is 16F877A

inspected the points described, there is no short, is that one of them is burned (IC7 and / or IC4)?

sorry for the english, translated

OE-24 unmark

IC7/10 - 0,01 Volts
IC7/11 - 4,96 Volts
IC5/13 - 4,96Volts
IC5/14 - 4,86 Volts

OE-24 Mark

IC7/10 - 0,90 Volts
IC7/11 - 0,01Volts
IC5/13 - 0,01 Volts
IC5/14 - 0,14 Volts

mode ECP+EPP With programmer not connected in the LPT1 IC7/10 - 0,01 Volts IC7/11 - 4,96 Volts IC5/13 - 4,96 Volts IC5/14 - 4,96 Volts With programmer connected in the LPT1 IC7/10 - 0,01 Volts IC7/11 - 4,96 Volts IC5/13 - 4,96 Volts IC5/14 - 3,38 Volts -----------------------------------------------...

My ezoflash 4v4 this with problems in OE.

OE-24 active in test/HW = 0.90 volts

0E-24 desactive in test/HW = 0

d0..d7 > 0,50 volts with OE desactive in test/HW

I tested with parmon.exe , the pin8 ( D6 ) of LPT1 always get 5 volts ( high level ) , the lpt1 is burned , Thanks to everyone who helped, I will test on another computer in another day , is possible to use an adapter paralel/usb?

all test test / HW passed except the D6, I am using a HP notebook , with programmer disconnect the pin 8 of Lpt1 always gets 5 volts( high level ), impossible use the programmer because of this setup LPT1 , is there any way to change this setting, ja tested EPP, ECP and always 5 volts on pin 8 of LP...

My ezoflash is with some short track or without contact , the D6-20 - BU3-8 , always 5 volts, already tested for short between tracks but apparently there is no short , can anyone help following a right direction .

Sorry this text was translated

following the image buffer to read the chip, the chip is the bios of a motherboard

Possible chip is not supported.

I also believe this because the recorder this ok

with AT29C010 selected returns 0x2F [...] - 0x2F, with SST PH29EE010 returns 0xDF [...] - 0xDF , trying to overwrite ( error - Write sector 0 ) , in test H/W , only the pin 11 - A10-23 the voltage this 4.60 volts on / 0.00 volts off, the rest is the voltage this 4.78 volts on / 0.00 volts off http:/...

the software they use is the SW 0.97g, the chip is generic ( TAIWAN ), the chip does not contain a description of the manufacturer, only the model 29C010D, I can not overwrite, delete, write, read only, the ID does not return any , the D of 29C010 (D) is the type socket of chip ( DIP ) tanks for res...

in my tests I read the chip 29C010D general, I used the configuration of AT29C010A (JUMPER 1,3,5), only read the chip, the recorder is OK with other chips
