Re: CH341a SPI / I²C programmer

Have you used this? Says it has a virus

Yes my virus scan said it was clean

Re: CH341a SPI / I²C programmer

Mine gave me: Suspect!3f217d4dbfec quarantined

[stj]

Re: CH341a SPI / I²C programmer

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?

25 series is SPI, 24 series is i²c
the letter(s) after the number can be ignored for now,
the next set of numbers relates to the size.

Have you used this? Says it has a virus

if it's originally from me, then it's direct from the site of the author.
anything over v18 is risky because they are in virtual containers that emulate a registered machine.

Re: CH341a SPI / I²C programmer

yes im sure it was the one stj uploaded i just never installed it but i have just installed it now on my laptop as my old version was v1.13 so using v1.18 now, i have also just run a full malware bytes scan and nothing found so should be ok to use.

Re: CH341a SPI / I²C programmer

Ok will try. What's the worst that can happen. It was quarantined

Re: CH341a SPI / I²C programmer

stj has his version in post 2 in a zip file so maybe download that and use his version, as i have that many versions on a usb drive it could of come from another source.

Re: CH341a SPI / I²C programmer

It's from China and a lot of AV programs detect it as virus, but it really isn't. I'm running version 1.34 I believe. It's something like 5$ or 10$ USD's and you get free upgrades for life.

One thing to remember, run the program as administrator. Another thing, with my actual programmer, I have the option for 3.3V TTL logic or 5V CMOS logic. My programmer has to be set to pins 1-2 (CMOS 5V logic), even for TTL devices. It doesn't make a difference and hasn't damaged any chip, but 2-3 makes the programmer not work. I use an 8-pin SOIC clip that helps a lot.

Some people have had success reading and writing chips in circuit, but I haven't. I've always had to remove the chips. How are you hooking the chip up to the reader / writer?

When my chips aren't detected, it's almost always because I have a bad connection between the chip and the programmer. If the buffer and the contents are in disagreement, generally that means you have a bad connection somewhere.

If you need help and can't get it working, I can try helping some more. I believe there's a 1.34 or 1.35 version I can upload. Sometimes, the chips aren't directly supported. For example, it might detect it as a similar chip, but I read the datasheet, and if everything that matter matches, it's okay (like file size, manufacturer, etc). They're kinda neat.

Re: CH341a SPI / I²C programmer

Does the latest version provide any noticeable benefit than 1.18?

[stj]

Re: CH341a SPI / I²C programmer

the guy just adds more devices each version.
given the chips use a standardised commandset, you can probably use unlisted chips anyway.
so long as you match the overall, and sector sizes.

Can you send pictures of how you physically have the chip hooked to the programmer?

Yes, you can use unlisted chips if you match them. But there are more things added.

Version 1.23

Simultaneous release of CH341AFree.exe V1.0 free version, only basic functions, free registration, only supports universal 24\25 chips, does not support special chips such as SST

Optimized the write speed of SAT\ESMT's AAI programming mode, improved a lot, but still slow

When the byte programming mode of SST\ESMT is increased, the data that is encountered as FF is directly skipped and the write time can be reduced.

Increase the amount of data that encounters the entire page as FF when the conventional chip is written. Skip directly to reduce the write time.

Increase the display file path at the title

Increase to the corresponding error location after verification fails

Increase the menu buffer -> reset, used to reset the buffer reset to FF

Fixed bug that individual chips cannot be erased

Fix bugs that are easy to "write operation timeout failure"

Correct the device number of the NN chip in the database so that the detection function can be detected

Optimize database chip names in order

Database removes 3 duplicate models of chips

The chip database adds 4 more chips

Fixed BUG that 26 series chips can not read and write, but the writing speed is very slow, similar to SST\ESMT

Added option to use block/sector erase mode, automatic selection of block or sector erase commands when enabled, and use of bulk erase commands when disabled

Fixed BUG error when registering the mouse at the chip select

Other minor changes are optimized

 

Version 1.19

Fix special chip protection problem of KH25L8036D

Fixed delay in the correction option can not save the BUG

 

Version 1.18

When using the automatic operation, when the verification fails, two message dialog boxes pop up.

Adding automatic operation can be delayed for a certain period of time before programming, which can be set in the options. (This function is for unstable chips. This option only works when automatic operation.)

Also, are you running the program as administrator? I always do. I'm assuming it shows that your programmer is successfully detected in the lower right corner of the screen...

Re: CH341a SPI / I²C programmer

Would be nice if they would add the option to add your own chips. I saw a programmer and it had that option. Don't remember which one it was

For the Chinese CH341A Programmer software?

I thought the same. I was thinking of building off some open-source programs that Stj linked to (I got some Linux drivers too for the CH341 chip, serial and parallel).

Thought when I found some time, as a community, we could come together, setup a github page and just write a GUI for Windows / Linux where users could add their own chip parameters and maybe upload them to some database. We'd store the database on the github page and could have the program auto-update the database with the click of a button or have a preference they can click to always check for the latest database.

I dunno if it'd catch on though and it's a bit of work, plus I got a few other projects going on now. It'd have to use something like the GTK Libraries for easier porting from Linux to Windows, and maybe some library that's available on both OSes for USB communication or something. It was just a thought.

How's that working for you? I see it requires .NET Framework, meaning it's a Microsoft Windows program, no Linux version. Is it free and does it support a lot of readers / writers?

I like how you can add your own devices. I thought you was using one of the softwares Stj talked about, the Chinese one or one of the open source ones.
