    Re: CH341a SPI / I²C programmer

    Can someone please confirm that their device can read/write to 24 EEPROM chips (any 24Cxx chip)?

    I've tried several different chips now, none have worked. I'm beginning to suspect my device or the software.

      Nevermind, it was my fault...

      I was laying the chip on the pads meant for 25 serial chips...

        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!
        sir can i have a copy of your version 1.29? thanks

            If you need the registered version I can put you in contact with the author. He will probably sell you a license for $5 or so.

                The developer of the software is pretty nice. It was 10$ USD for me for the latest version, v1.31, with free upgrades he says. I had trouble tracking him down, even though his e-mail address is in the program. I didn't realize it was an e-mail address because the font was a little funky. It's SkyGz@QQ.com

                Just tell him you're looking to purchase a copy of the CH341A Programmer. He'll ask some questions, send you an e-mail with the new version, have you tell him the Hardware ID, and then send you a registration code. For 10$, you can't really go wrong.

                Although his website is in Simplified Chinese, he understands English very well.

                Just thought you guys would like to know.

                  Re: CH341a SPI / I²C programmer

                  I just got one of these CH341A Programmers for TV eeproms.

                  Version I found is 1.13. Where can I get 1.18? Reading that it works well for people

                  Also does it have an auto detect feature? If not how do I figure out what type of eeprom it is to select in the program?

                    This should be version 1.18

                      Great thanks. What I’m confused about is when using an eeprom from a tv, it doesn’t give a detect option unless I use the 25 SPI BIOS slot, but this wouldn’t be for an eeprom correct?

                          Ok so my problem is the eeprom chips I bought aren’t detectable. They’re a Winbond W25Q32FVSIG

                            Is there a way to add them to the list somehow or I need to get a different brand?

                              try flashrom

                              btw, are you sure they are connected right?
                              any 25 series should be detectable, even if it's not supported.

                                Flashrom a program?

                                And they’re connected right it doesn’t detect just shows all values as 0

                                And if I try to program it will sometimes complete but when verifying says “chip with the contents are in disagreement”

                                Btw how do you know if it’s a 24 or 25 series? I’m not too familiar with eeproms

                                  Ah actually it finally detected one. After trying 4 from a strip of 10. So they must just be a junk batch

                                    given the bs i went through last week, they probably got stolen from a production line for DELL motherboards!

                                      What happened?

                                      Also I’m new to this eeprom thing, for future reference how would you know what size memory and whether it uses SPI or I2C when shopping for blank ones? Or is there one common type used in TVs that differs from a PC?
