And, so finally, I've done something that at least hints of being musical with my Atari Paddles.

This shows how to use them as a MIDI CC controller.

Arduino MIDI Atari Paddles

Finally, I get to the point where I can do something vaguely musical with my Atari 2600 Controller Shield PCB. This turns it into a simple MIDI CC controller using the Atari paddles. Warning! I str…

With all the comments about Arduino Opta, and an integrator from Slovakia telling me about his experience with industrial shields PLCs, I must admit I'm curious about this brand and it's capabilities.

And immediately followed by a simpler version, thanks to the observation by @bytex64 that the originals wouldn't have used ADCs at all! :)

Just goes to show that sometimes we can't "see the wood for the trees" in some of these things! And we are spoiled by our modern tools.

Was this a #MakerFail ? Not sure. Certainly some learning going on there though :)

Atari 2600 Controller Shield PCB Revisited – Part 3

Following on from Atari 2600 Controller Shield PCB Revisited – Part 2 someone on Mastodon made the point that the reason they tended to use RC circuits to read paddles “back in the day”…

My 6yo son and I made a “Cricket in a Can” with bits and bobs we had laying around. A simple gadget and not too pretty, but it chirps like a cricket when you tap the can. His 2yo brother thinks it’s hilarious!

I think this will be a fun little platform for the #kids to learn & play with software to make simple piezo music. 🦗🎼

And now I can properly "properly" read all four paddles.

But that was a lot more complicated than I thought it would be. Even by the standards of my previous "that was a lot more complicated" statement!

Maybe I'm just a bit slow with this one! (or getting old) :)

Anyway, I finally have something I'm happy with. Now to actually do something with it!

(the things one does to avoid cracking open some vintage gear and changing it...)

Programmed on a single Arduino Mega 2560 using timer interrupts.

The source code can be found in "examples" directory in the my book repository:
https://github.com/artyom-poptsov/SPARC

I'm working on a chapter in the book that is dedicated to low-level MCU programming. The current goal is to cover enough material to properly explain how to do such projects.

I am ALL for #AI and #Claude and #GPT, etc. I do however, in my free time outside of work, school and creating STEM tutorials to help the next generation, believe that spending time in pure #Assembler in a bare-metal #Embedded #microcontroller will help you understand #Computer #Science in a way that can help you drive the future in #technology. I have and will continue to post pure Assembler drivers to help others achieve this utilizing #Arduino and #STM32 products.

Lucky that this header just happens to have CLK on it.
Show threadgloriouscow3d ago
Conspicuously absent on the 386 is an ALE pin. I guess timings are now tight enough that you only concern yourself with the address when a read or write signal is asserted.
Show threadgloriouscow3d ago
No bus status, no ALE pin... I guess I know the CPU has reset if it just reads something.
Show threadgloriouscow2d ago

And I thought the 286 took a long time to reset.

450 cycles!

Show threadgloriouscow2d ago

So far no response from the 386EX.

Time to do a sanity check to determine whether the RESET and CLK signals are really reaching the CPU.

Show threadgloriouscow2d ago
The header provides a tie to /RST, that is an inverted RESET signal. This is one of the signals that passes through the inverter IC, a 74HC14D. I should check that the inverter is still receiving power after my board surgery, and that a positive RESET signal is coming out the other end of it.
Show threadgloriouscow2d ago
Well, this is unfortunate. The holes in the board i assumed were for mounting posts actually seem to be connected to each plane and by putting screws in I have shorted the board.
Show threadgloriouscow2d ago

The EX datasheet doesn't mention the particulars, but the SX datasheet has this to say:

I'm not sure how this board ties the busy pin. If it isn't low we're gonna be waiting a million cycles for it to reset.

BUSY is multiplexed with TMRGATE2 on Pin 92. It looks like this runs through a resistor network with a pulldown to ground (figures) but does go to a header pin curiously claled TMRCLK2. Typo perhaps? I hope so.

@gloriouscow Maybe they replaced it with a BEER pin?
