My own GBZ project

Post by correia5022 » Mon Dec 05, 2016 3:15 am

Hey guys!

(please be advised that i'm a noob)

I'm starting my gameboy zero project, and i've searched some LCD's, and come up with this one:
LCD module Pi TFT 3.5 inch (320*480) Touchscreen Display Module TFT for Raspberry Pi 3

https://pt.aliexpress.com/item/Free-Shi ... Title=true

The LCD has higher resolution than the ones on projects. Can i use it on the raspb zero?
Or it must be LCD's with 320*240.


My other question is, can raspberry zero handle a LCD directly with its 40pin?

Thanks in advance!

Hi people.

Although no replies so far, i have other question:

Can i replace the "TEENSY" for a "Arduino Pro Mini 328 - 5V/16MHz"?
Can anybody help with programing?

No. The 328 Does not support USB HID.

Look for an Pro Micro clone with an atmega 32u4 controller.

Check the guides, there are a couple of examples there.

Hmm, ok, so an "Leonardo Pro Micro ATmega32U4 Arduino IDE Bootloader replace Pro Mini 328P" can do it?
It's a lot cheaper

Yes.

For example, take a look at the guide by sota:
http://www.sudomod.com/forum/viewtopic.php?f=22&t=1766


Concerning the screen.

It will have better picture quality compared to composite, but it is using SPI, so the refresh rate will be low (probably to low). Also it will not fit, because it is to width...and.....last....it's screensize is not 4:3.

Thanks a lot.
The tutorial by sota is excellent! This controller keeps the project "low-budget"

well, another dumb question.

In the wiki page, http://sudomod.com/wiki/index.php?title ... c_Hardware, it refers to capacitors 10nF , and a 33nF capacitor.

i fond two versions:

OR

https://pt.aliexpress.com/item/High-Pre ... Title=true

Which is the best?

well... the second link has a higher voltage rating of 3KV but the first link is already 1KV which is waaaaaaaaay over the voltage you'll be seeing already so neither is really 'better' for this (based on specs. one could be made better, you just never know with aliexpress. probably both are lying about their rating, but both will be more than good enough for this audio filter.)
