Re: CH341a SPI / I²C programmer

what software version is that?

looking with a hex editor it looks NOTHING like 117 or 118 and has no version strings or anything.
what it does have is words like "encryption" and "login"

btw, can you download this???

should be an "about" box or something.

[stj]

Re: CH341a SPI / I²C programmer

the one on the ebay link is 1.17 btw.

Re: CH341a SPI / I²C programmer

version 1.13

[stj]

Re: CH341a SPI / I²C programmer

well i got that chinese Vdrive file down.
it's passworded: 13579

and contains 1.18 software + drivers + some type of atmel programmer.
also a big load of eeprom dumps and some documents.

Re: CH341a SPI / I²C programmer

soooo.........
now i may have found version 1.26

Re: CH341a SPI / I²C programmer

o.k. for anybody who owns one of these.

there are 2 windows drivers to install.
1: a virtual comport
2: a virtual parallel port and i²c driver

then there are 2 softwares.
1: the memory programmer
2: the AVR microcontroller programmer

now as far as the memory programmer goes, the versions upto 1.18 just work
versions from 1.20 onwards need to be registered.

and i have 1.18 and 1.29 if anybody needs them.
------------------------------------------------------------------

btw, the key to finding this stuff is simply to use a chinese search engine - it's like turning on the lights in a dark room!

Re: CH341a SPI / I²C programmer

Can we change the language in these? like in the one in the youtube link.

[stj]

Re: CH341a SPI / I²C programmer

open the file "Config.ini"
change the language setting to say "language=1033"

the default path to open and save files is in there if you want to change it too.

Re: CH341a SPI / I²C programmer

Thanks for the info stj ive only brought the programmer to try to add the spftware to a eeprom on a technika tv/dvd combi i have a issue with freeview wont tune i have found the bin? file here http://www.tv.quuq.org/forum/index.php?topic=6012.0
stj do i read my old chip save the old file and then unzip the down load and add all the files? its the first time im trying to do this sort of thing anyadvice you can offer?
the set was a freebie so ideal for expermenting with.

Re: CH341a SPI / I²C programmer

firstly, you ALWAYS save a backup of the original data - incase you make things worse.
then you can atleast recover to where you started.

can you upload the file you want to write.

[vinceroger69]

Re: CH341a SPI / I²C programmer

this is the one i have downloaded cheers.

[stj]

Re: CH341a SPI / I²C programmer

read the old chip,
save the file.

unzip that archive and load the .bin file into the programmer.
then erase the chip (you cant program a chip unless it's blank)
then program the chip.

Re: CH341a SPI / I²C programmer

Re: CH341a SPI / I²C programmer

probably not a good idea.
when you use those you have to stop the host system from trying to access the chip at the same time.

the other thing is chip width.
there are 2 sizes, narrow(150mil) and wide(200mil).
those clips are designed for the narrow chips usually like 24' series eeproms.
the 25' series flash chips are usually wide.

this may be more helpfull
