Port status LEDs

[dberlin80]

Hello,
I made myself a blueretro adapter for each my PS2 and Dreamcast which work fine with my bluetooth controllers. Great project, thanks :)

Now I wanted to get a step further and add the port status LEDs.
The issue:
The LED on IO2 works fine, pulses and gets solid when paired. But the LEDs on the other IO ports don‘t pulse or light up. They remain OFF. I tested all other LEDs on IO2 so they’re good.
Any hint?
Thanks much.

I noticed they'll stay off (with the exception of port 1) unless you manually put it in pairing mode - but if you connect a 2nd controller that IO should light up solid.

Ok, so I tested everything out and it was the just as you described thx :)

@dberlin80 when you wired what MOSFET did you use? Do you have a part number?
thanks

Darthcloud mentioned somewhere that you don’t necessarily need one to have it working. By now I made two- one with and one without and he‘s right. If you want to make it properly however, then you can use any standard nmosfet- I used this:

Yeah I saw that post but had trouble getting it to work. How did you wire it up without?

[dberlin80]

I‘m honest… I forgot which wiring I exactly used as I closed both systems(built it inside the consoles) but it was either step 7 here:

Or the actual way intended with a mosfet but where I just left it out.

if you skip the mosfet wire like this

3.3v is the esp32 pins

0v is GND

Ok I got this to work for all 4 now. I'm just using a 100 ohm resistor and I swear my LED is the other way around but it's working.

I was also doing something stupid where I had the firmware set to universal but it wasn't plugged into a system (I'm still waiting on some parts) this was causing the P1 LED to just be always on. I found if I went int the config and selected Dreamcast or If I programmed it with the Dreamcast firmware all lights worked as expected.

Thanks for the help everyone!

I stand corrected the LED was oriented the way you said. Here is the diagram of how I have it connected
