PCE 6 buttons pad issue #9

Open sk8er000 opened 4 years ago

sk8er000 commented 4 years ago

I've made 2 cable adapters for PC-Engine following the schemes. If I use a regular 2 buttons pad they work with no issues but if I try to use a 6 buttons pad (I've tested the one that came with the PC-Duo RX) it detects the UP and LEFT directions always pressed. If I use the pad on the PC-Duo RX, PCE or Supergrafx it works

Could you please test with the attached firmware and let me know the results? LLAMA.hex.zip

sk8er000 commented 4 years ago

Is there a suggested update procedure?

bootsector commented 4 years ago

Are you using the DIY version with the Arduino Leonardo?

sk8er000 commented 4 years ago

I'm using the version assembled by Bruno Freitas

bootsector commented 4 years ago

That would be me! :)

What operating system are you using so I can give you the right steps?

sk8er000 commented 4 years ago

Didn't know that :D I mainly use Windows 10 but I can use other OS if needed

bootsector commented 4 years ago

1 - Install the DFU driver by right clicking the dpinst64.exe installer in the drivers directory of the attached zip and running as admin (assuming you have a 64bit Windows OS).

2 - Connect the P1 DFU jumper and connect the P1 USB to your PC via USB

3 - Double click the flash.bat file for updating the firmware.

4 - Repeat 2 and 3 for updating the second port

Let me know how it goes!

Thank you for the guide. I've flashed the new fw! Now the up direction works fine but the left direction is still pressed. If I press the right direction on the test pad ROM the left direction is not pressed anymore but neither the right direction. The 2 buttons pad is still working with no issues

bootsector commented 4 years ago

Aside of the left direction being pressed, all the other buttons work correctly?

sk8er000 commented 4 years ago

Yes they're working fine but I've discovered a strange behaviour: -Actually I have the P1 with new fw and P2 with the old one

Tested with 2 different pads and 2 different adapters

bootsector commented 4 years ago

Hmm... That's a really odd behavior. It's leaning to a bad connection somewhere. Only change from original fw to the new one I've sent you for testing is decreasing the frequency we talk to the controller. I'm attaching here a new hex so you can flash and test (now with an even slower frequency) LLAMA.hex.zip

sk8er000 commented 4 years ago

It's still working in the same way. The strange thing is that there are no issues with the regular pad on the directions and that the UP direction was fixed by the firmware. Otherwise the issue was obviously related to the wiring. Since on the github there is only the scheme for the TG16 port adapter I've used a second scheme to traspose the TG16 signal to the PCE ones: pce

the other strange thing if it's a connection problem is the same on both adapter and using 2 different pads (same model)

bootsector commented 4 years ago

Could you please give it a try with this one and let me know? LLAMA.hex.zip

sk8er000 commented 4 years ago

Now both models (2 and 6 buttons) are working with no issues!

sk8er000 commented 4 years ago

Edit Sometimes the left button is detected even if not pressed but is mainly working

bootsector commented 4 years ago

Just pushed this commig: https://github.com/bootsector/LLAMA/commit/6a01088b381b4b94614d69b81a3c75c0e6b575ef

I think there's something odd with the pullup resistor connected to your 6 button controller's left button.

bootsector commented 4 years ago

This is the latest commit but I've increased the delay from 20us to 40us. Could you please check if left button is still flaky? LLAMA.hex.zip

sk8er000 commented 4 years ago

It seems to work, I'm sorry for all the trouble, unfortunately I've got only 2 6 buttons pad that were bundled with my pc duo Rx and I don't have other 6 buttons pad to test. This models are considered to have a clunky dpad, I'll try to open and inspect them but now it's much better than before! Thank you

bootsector commented 4 years ago

No problem. Let's keep this issue opened until we get this 100% figured out. Does it work better with latest zip or same thing as the previous one?

sk8er000 commented 4 years ago

Now it's working a lot better sometimes if I hold firmly right it's been detected like if it's an autofire button (it's repeatedly pressed very fast instead of being firmly pressed). But it seems a pad issue rather than a fw issue (I'll check it soon). Tested other 4 original pce 2 buttons pad (various models) and everyone is working properly.

bootsector commented 4 years ago

I think that it could be a good idea to check if the VCC on your DIN/mini-DIN connectors are really giving out 5V too.
