Works in BIOS, not ingame

[sirjeannot]

Hello,

first thanks for your library, it's really a saver.

Based on your lib and usbhost, I've connected a ps3 controller to the gamecube. Everything works inside the gamecube bios, but ingame (fzero) no input are registered.

Code is here : https://github.com/sirjeannot/GamecubeBT/blob/main/GamecubeBT/GamecubeBT.ino The only thing I've changed from the templates:

• the gcwrite is called only when necessary, otherwise I have continuous gcwrite errors (loop probably too slow, based on your previous messages in other issue discussions, but the usb operations are slow :( ) > possible disconnect? I'm trying to get mario football to verify. For the record I managed to send only one keypress right after the controller is connected...
• (PS3BT / USB HOST v2) rather than using getButtonClick (single event) I'm using getButtonPress (trigger event as long as a button is pressed, I don't want to be mashing direction buttons to move around) > should not have any impact

I was wondering if the behavior of the console with the controllers is different within the BIOS and ingame. I was wondering also if the gcwrite should be called on every loop. If yes, my only way out is to use an arduino for BT, one for the Gamecube and send keypresses on different pins.

Thanks!

1. Every Game handles the controller on its own. So polling times are different
2. Mostly you need to answer EVERY call from the console, so the loop needs to be fast
3. USB Host is expensive

I'd recommend using 1 arduino for gamecube communication and use a serial connection with a lot of (custom) error connection to transfer the data from a 2nd arduino. For example:

Arduino with USB:

1. Poll usb data
2. Send Data to 2nd arduino with a start/stop mark + checksum
3. Repeat

Arduino with gamecube connection:

1. Discard serial buffer (read until nothing is available)
2. Read serial data until a valid package was received
3. Talk with the gamecube
4. Repeat

You can use up to 2M for serial speed, you must experiment with that. You have to be fast!
