Cheaper than Teensy

[Ivoah]

I didn't read the entire thread, so this may have been suggested, but you actually don't need a separate chip to handle the inputs at all. The Pi can use its GPIO pins as keyboard keys. I made a more detailed post about it here: http://www.sudomod.com/forum/viewtopic.php?f=8&t=458

Sorry for the dumb question.
What are the advantage of using this solution rather the GPIO pins from RPi3? Isn't cheaper and faster? Also supports multiple press.
(unless we need the GPIO pins for other stuffs).

Thanks.

Same deal, lots of wires, it takes more space. Plus the RPi3 has a quite bad power consumption for a portable console..
And we are lazy, this is nearly plug and play once you've done the hardware part. Your solution require some kind of virtual joystick and such, if you need for any reason to format your SD card, you need to do everything again. Here it is handled as a controller, it works instantly

First, what does a Pi3 have to do with this? Also, it wouldn't take any more wires than using the teensy. You're remark about the SD card is true, but I think the price and complexity reduction is well worth a minor inconvenience if you need to replace the SD card.

I would buy one obviously, since I'm making the code that would be nice to be able to test this, PM me as soon you have what's needed, want to be #1 tester :p

By the way, have you programmed them with Arduino bootloader or do you make a header to do this ?

I have a USB plug and also a the 6pin ISP header on the board so it can be programmed both ways. I haven't decided on what to program it with yet, maybe leave that up to the end user or maybe you can give me a suggestion

I'll definitely send you one of the 5 so no need to worry.

The RPi3 is because the author of the post you did not read that contains the awnser was using a RPi3.
The finnancial cost is indeed a factor though here we deals with ATMega32u4 which costs less than 10$ which worth it

Yeah my best guess would be to buy pre-programmed atmega with arduino bootloader so that the user can update it through Arduino program, but if the chip are not pre-programmed ISP would be my second guess

Here is the image of the board in Eagle just o give you guys a heads up on it's look. I tightened some of the post holes as I didn't like some being too big for the tiny posts, added the audio buffer added, have 2 usb connection methods with a cable or wire method, ISP header, L1/L2 and R1/R2.





EDIT: To anyone who has successfully installed a stereo amp with volume control could you PM me the way you set it up? Not interested in USB audio as I have space for an amp on this and would like to add it in there.

This is insane. So much work, you rock!

Because of the nature of the board once the tests prove to be functional (it should!), these will be a limited run since I have to hand solder these bad boys and that can take time although I have a plan to streamline the process a bit.

Wouldn't it be faster to reflow oven it ? If so you could do a DIY one (That would be a nice project to do)

[Helder]

That is what I plan to do but even that takes times but will be much faster than hand soldering. Either way it depends on demand how many I'll get once tests are good.
