Yes. Presumably the recalibrate command would have the same format as the get origin command. The "long status" command would happen to be this format as well: all analog values get a full byte. If his implementation is correct, the output would effectively be the same, but interpretation the...

Yeah, I figured the polling mode was game dependent. I noticed the 0x43 command in this project, which seems to be the most accurate controller emulator I've found thus far: https://github.com/extremscorner/gba-as-controller/blob/gc/controller/source/main.iwram.c His implementation of the...

Seem to have sorted out the stability issues, my breadboard setup connection to the controller cable was janky. Analog functionality is working well. I also hooked up a logic analyzer to a stock controller to learn about the behavior. Some notes and a couple interesting points to notice when...

Update: implemented analog readings with ADC + DMA, works well. Encountering some stability issues though that I'll have to debug on the scope. But I think I'm getting close to something functional.

For awhile now I've been interesting in implementing something like GC+ to the STM32 platform. I was bored over the school break so I decided to get cracking on this using a NUCLEO-G431KB development board I was using for my Wii Pocket firmware (I will get back to that soon, I promise..). I...

It is an open-source project for hardware emulation. People recreate (or in some cases reverse-engineer) the hardware for a retro system in HDL (a MiSTER core). HDL is essentially a "programming language" to describe hardware logic, which is used to program an FPGA to implement the circuit. The...

The speed and number of channels you should get depends on your application, but I would suggest not buying one until you actually need it. Then you can buy one based on your needs.

Short answer: no Long answer: If you plan to be an engineer, then you will probably want one at some point. For making a project like a portable? Not at all necessary. They are useful for debugging hardware that involves time-varying signals (such as digital protocols, analog waveforms etc)...

Not me, but here's the info https://bitbuilt.net/forums/index.php?threads/what-exactly-is-the-u10-chip.3223/post-39168

Awesome!! But as a clarification, the optimal clone hero setup is a Wii guitar hero controller + the Raphnet wired adapter, as it can achieve a 1000Hz polling rate.

Looks amazing! So great to see how far you've come. Can't wait to see what comes next!

Amazing work!

6 layer Wiis produce a lot more heat, so achieving the form factor you want will be significantly more challenging unless you switch to a 4 layer, highly suggest you do that.

You can cut off the extra components

Should be fine

No problem, I understand this can be a frustrating process. But with your level of detail I'm sure you're going to finish with a great end product!

One immediate thought is that perhaps the U10 via soldering is not reliable. Some boards (like this one) don't expose the copper on the vias very well. You might try desoldering it, and manually scraping some soldermask off. Typically, I test my U10 relocation before the trim to rule this sort...

It sounds like you've been very careful and thorough. Can you post an image of the back of the board? A picture showing the entire area of the back side of the board is sufficient for now.

So the information I've gathered so far is that you've checked all the voltage rails and they are acceptable when powered on, you've gone through the U10 trouble shooting guide and there's no problems there, you currently have reset shorted to ground, and the display is recognizing some sort of...

Those seem reasonable to me. Did you make sure that the MODE pin is not connected to 3.3v when testing composite? Do you get a "no signal" screen or a black screen when powering on?
