RGB Light Patterns about python-keyboard HOT 7 OPEN

We can add a blacklight update function after matrix.wait(), and add a timeout to matrix.wait

matrix.wait(10)
# change backlight
backlight.update()

Another way is moving backlight into circuitpython firmware. Use timer's callback to update the backlight. It will be better, but will take more time to implement.

I have been doing some initial playing around with this. Initially just playing around with adding the lines

self.backlight.pixel(key, 0xFF, 0x00, 0x00)
self.backlight.update()

at this line

I'm having some weird behavior depending on where I put something like self.backlight.update(). If I put it right after the wait like you said, I get some nasty errors that I don't quite understand yet and cause the keyboard not to run. Do you have any idea why putting the update function or pixel setting in different locations in that function causes it to error out?

The 7th bit of key is 1 when the key is released. Should change self.backlight.pixel(key, 0xFF, 0x00, 0x00) to self.backlight.pixel(key & 0x7F, 0xFF, 0x00, 0x00)

Do you mean what was happening in this line? Or should I be doing it again?

from python-keyboard.

Oh, not need to do it again. I don't see any difference when putting self.backlight.update() in different locations.

I tried to replace the get function to:

    def get(self):
        key = self.matrix.get()
        if key & 0x80 == 0:
            self.heatmap[key] += 1
            self.backlight.pixel(key, 0, 0x80, 0)
        else:
            self.backlight.pixel(key & 0x7F, 0, 0, 0)
        self.backlight.update()
        return key

Do you mind to create a branch to share your code? So I can check it.

It turned out to be another issue. I was able to fix it. I am currently using something similar to what you put except a check to see if it's the spacebar and in that case light up all 3 LEDs (56, 61, 62) and it's working great and the latency while it went up isn't noticeable during use (7 nanoseconds)

I just opened up a PR with the current state of this development (#10)
