    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???

        it's the blue button one from the left, but the download is so slow it never completes for me!

                  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.

                      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!

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

                          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.

                              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.

                                  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

                                      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
