Hey, I've been trying to build a system based on your flasher, but I cannot understand your explanation for the pin connections. Can you provide a schematic of some sort, or at least explicitly specify which pin from the Arduino connects to the shift registers and which - to the flash chip.
Thanks!

Check out the new table in README.md. It should make things much more clear. The old instructions were not clear at all.

I also merged your changes to the computer program and made further enhancements to the computer program.

Thank you, that's exactly what I meant. I'll try to make an actual schematic for this when I finish the build, just for completions' sake.

Excellent, I will close this issue once I receive confirmation that you were able to build the programmer and it works correctly for you.

Hi.

Because labels you used here:
github

are far away from the datasheet labels:
datasheet

Could you please confirm if my circuit diagram is OK?

I thank you for making the nice looking schematic diagram. I looked at it and it seems right however actually I'm not entirely confident in if I have everything right in the code regarding the bit order in which everything is sent to the shift register. The problem is I think it's been over seven years since I've built this.

I would recommend trying what you have and if it works with your permission I'll adopt that as the official schematic.

If it doesn't work try reversing the way shift24 works. If that works I'll adopt that change along with your schematic.

If that still doesn't work then I apologize. Try looking at the way the code works.
