Re: How do you know you made static damage?

in fact under the heading "Static-Handling Precautions" of the logic-families page of the primer, you'll see that I say I myself don't use a wrist strap
Oops I might have added that thing about the wrist strap in my head :oops: seeing the "getting away with an antistatic mat" portion triggered in ...

Re: How do you know you made static damage?

Pfeww seems I'm safe then I didn't notice any effet that you said and it's pretty moist where I live and I have laminate at home.
Never had electric shocks while working either.

Thanks for the information :)

How do you know you made static damage?

Hello everyone

I'm currently reading the 6502 primer and on the part where it says "work on an antistatic mat and wear an antistatic wrist-band", I told myself "welp, never did that" :(

How do you know you made damage to your components? Do they simply stop working? Or do they behave unexpectedly ...

Re: [WDC65C02] STA writing when it feels like it?

Want to give the chap a moment to breath
That's amazing :D would never have thought such an old CPU had still a so active community

I just made myself a 5v power supply from a USB cable like suggested by BigEd and ThisWayUp and well, things are looking much better! I'm having a really consistent ...

Re: [WDC65C02] STA writing when it feels like it?

How does the Arduino know when the clock transitions will happen?
The clock is plugged to the Arduino and an interrupt method is called on the rising edge of the clock cycle to read the addresses and data pins

Welcome, Doko. You seem to have several problems that I think will be solved if you go ...

Re: [WDC65C02] STA writing when it feels like it?

You're probably right! Only problem is I only have a 9v power supply on which I can plug a 9v battery, what should I get to generate a 5v supply?

Re: [WDC65C02] STA writing when it feels like it?

Thanks for the welcome guys :)

I don't notice any clock source.
I'm using a hand made clock made out of 555 in astable for a 1Hz clock and monostable mode to single-step the clock

And you've not included a schematic for us
I'm kind of beginning electronics and don't know a good website to make ...

[WDC65C02] STA writing when it feels like it?

Hello everyone

I'm currently following Ben Eater's tutorial on 6502 Hello world programming and I'm facing an issue with the STA instruction :(

It seems that sometimes, the STA doesn't execute itself and I don't know why!

This is the kind of output I get:
