I already have one in there to handle the serial-to-parallel decoding. The others are mostly for driving the latch pin every 8 clock ticks, and for syncing the signals.
What do you suggest? I'm open to ideas.
I tried to expand on my #RetroChallenge and build an #RC2014 module that could decode the 8 bits returned from a NES controller using just 74 series logic and a 555 timer.
It didn’t work. I think I have the timing slightly out so some of the logic is triggering too early. I need a dual scope!

RC2025 – Part 9 – Using a SNES controller - Robert Price
Extending the RC2014 NES controller module to use a SNES controller instead, and using Z80 assembly language to read it.

The #RetroChallenge may have finished, but I have a bonus post.
The SNES controller is an extended version of the NES controller.
So, I have reworked my #RC2014 NES controller module and Z80 assembly language example code to use the SNES controller.

Smoke me a kipper!
That’s great! I always wanted one back in day. I’m tempted to make my own now.

Great to see the ZX-RC2014 Bus Interface in use here to use Robert's RC2014 NES Controller module on the ZX Spectrum!
The Bus Interface gives your #ZXSpectrum two #RC2014 expansion slots and with an optional ZX through port too. Info/Purchase at: 2014.samcoupe.com

RC2025 - Part 8 - Playing Manic Miner with an NES controller - Robert Price
Attaching an NES controller module to a Sinclair ZX Spectrum computer and hacking the classic game Manic Miner to use an NES controller.
www.robertprice.co.uk
It's the final day of the #RetroChallenge so I've written about my finished project.
In this post I explain how I was able to connect my RC2014 NES Controller module to a Sinclair ZX Spectrum, and how I hacked the Manic Miner code so I could use my new module.

My most popular cartoon by a long chalk is also oddly niche, in that it mostly appeals to a generation who remember the song it refers to and enjoy the nostalgia for their youth. I can draw one for you if you like.

RC2025 - Part 7 - Moving a pixel with a NES controller - Robert Price
In this article I show how to move a pixel around an 8x8 LED matrix display by using an NES controller on an RC2014 computer.
www.robertprice.co.uk
I teased this a few days ago, but here's the latest part of my #RetroChallenge
I've been able to put together the various parts I've already written up, and I can now move a pixel on a LED matrix using an NES controller on my #RC2014.

RC2025 – Part 6 – Using an 8x8 LED matrix from Z80 assembly language - Robert Price
Looking at how the 8x8 LED matrix module works on an RC2014 computer. Example code is given in both BASIC and Z80 assembly language.
www.robertprice.co.uk
I've been using the 8x8 LED Matrix module on my #RC2014 recently as part of the #RetroChallenge
I've written up how it works, and also added a demo program in Z80 assembly language converted from the original BASIC example.

Creating a reusable Z80 assembly language subroutine to read an NES controller. The subroutine is tested by outputing the received byte to LEDs.

I've written about creating a reusable Z80 subroutine to read the NES controller on my #RC2014 computer as part of this year's #RetroChallenge

Thanks, it’s been really fun, and I’m learning a lot.
More progress on my NES controller module for the #rc2014 #RetroChallenge.
I am now able to move a pixel around on an 8x8 LED module using the NES controller.
Lots to write up over the coming days.

I’ve plugged in the 8x8 LED matrix for my #RC2014 for the first time in ages. The first job was to rewrite Shiela Dixon’s smiley example from BASIC to Z80 assembly language to help me understand how it works. It’s definitely working :-)
All fixed, changed a z80 rl to rr.
More work on my #RetroChallenge today. I was taking the out from the NES controller, reassembling it on the #RC2014, and showing the output in the red LEDs. I then noticed that I’ve accidentally reassembled the byte backwards. Oppps
Yes, I guess that would save a byte.
Happy Friday!
RC2025 - Part 4 - Bit-banging a NES controller using Z80 assembly language - Robert Price
In this article I bit-bang an NES controller from my RC2014 using Z80 assembly language. The results are then sent to the serial terminal.

I've been working a bit more on my #RetroChallenge, getting an #RC2014 to talk to a NES controller.
In my latest post, I explain how I've used Z80 assembly language to work out which buttons are being pressed and to print this back over the serial terminal.

I've soldered up the PCB for my RC2014 NES Controller #RetroChallenge
Thankfully, it all seems to work, so I've written about how to use this from MS-BASIC.
