Vial Matrix Tester seems cannot be used
It seems Vial Matrix Tester is cannot be used. It doesn't respond to any input.
Pro Micro RP2040 (16M flash) rmk v0.4.1
@HaoboGu any idea what pieces of the protocol need to be implemented in order for this to work? I'm not that familiar with Vial's protocol, and so far I haven't found the specific command(s) related to this feature.

It's SwitchMatrixState event, the qmk implement this way. However, it's hard to do it in Rust. I don't know if there's a easy way to implement this 🥲
Is there a plan to support "NKRO"? Because that (if I know right) NKRO also needs the state storage of every keys, not only 6 + modifiers. But of course there is a difference: vial needs the phisical keys, while NKRO needs the "after mapped to FullSize" keys pressed state...
Also, I was wondering why register_keycode() has this strange code inside:
// First, find the key event slot according to the position
let slot = self.registered_keys.iter().enumerate().find_map(|(i, k)| {
if let Some((row, col)) = k {
if key_event.row == *row && key_event.col == *col {
return Some(i);
}
}
return None;
});
Why is that dealing with row/col positions??? Maybe to use it for VIAL matrix tester?
Adding a note here. Before we add support for vial matrix tester we need to implement the vial security feature, otherwise a malicious program can use the vial protocol to implement a keylogger
