The CH341A doesn't read anything, but maybe that's because I'm a noob :D

[Jérémy Vanbaelinghem]

Hello,

I'm desperately trying to get my CH341A to work, but it seems that all my attempts have failed. Despite everything, I want to check that it works, the aim being to read at least one chip and “screenshot” the configuration for me to use as a reference.

Here are the steps (software part):
- I'm running Windows 11 Pro 64-bit (10.0 build 26100)
- Drivers are installed (no error messages) and there are no problems in the Device Manager.
- Set the language to English (to avoid the CH341A's basic software bug)
- Does not work on AsProgrammer 2.1.2, CH341A_134, CH241A_V2.1 and NeoProgrammer 2.2

Here are the steps (hardware part):
- See the 2 photos to understand pin positioning (on programmer and clamp)

Is everything normally connected correctly?
I'll keep investigating

Thanks for your help,

i cant see if you have the jumper on pins 1&2,
also you have the adapter/ribbon in the wrong way around.
pin1 of the chip/adapter faces AWAY from the usb connector

And how do you want to count, record a dump with a clothespin from 8 pin from a 16 pin chip....

Yes, there is a jumper on pins 1 and 2. I can't figure out the orientation of the wires. If possible, can you draw me a diagram (even on paint ^^) describing exactly which wires go in which direction? I've tried it with your images attached, is it any good?

Interestingly, when I put the green adapter on the right-hand side and connect the clamp. The run led (bottom left of the programmer) lights up (depending on the connection, it dims or increases in intensity) but if the green adapter is on the left of the key, the run led doesn't light up.

On the other hand, my clamp doesn't stay in place and jumps out every time I try to fit it onto the winbond chip. If you undo and redo the clamp a million times, could this have an effect on the grip?

Ah ok the ch3741a can't reprogram this chip ^^'
Otherwise the connections are good?

For spi flash (25 series) the connection is indicated on the programmer itself. You need to unsolder the chip and program it through an adapter. Or an adapter SOP16 to DIP8.

You are mess arround with pin connection of adapter, and wire and clip (soic-16 ic...), it is no strange that did not work. On ch341 ziff socket, there is only two position: very top 8 pins, and very botton 8 pins. There is no any "middle" position for valid connection. Orijentation of adapter is that pin#1 is toward lever of ziff socket, for both position, and red wire is as close to pin#1 of adapter. On other side, 8 pin clamp, claw... red wire must be on pin#1 of 8-legged ic, either 24xx or 25xx or other... if you using that clamp.
