Can't turn on/off the led light in program change?

Can't turn on/off the led light in program change?
It turns on but doesn't turn off.
It works fine in control change, but in program change I can't turn the led on or off.
please tell me how

Please try with the attached firmware - there was one issue with that. But normally, if the LED is configured to be controlled with Program change 0 for instance, you turn it off by switching to any other program change. Note: when you send program change to the board, the board switches preset first.

By the way, I was testing my own controller with a touchscreen set to 38400 and didn't experience any slowdowns. Weird.

maybe i'm doing something wrong
But there is no problem in using it.
After downgrading to 38400, it seems to be more stable.
thanks

Can you send me a video showing the slow response?

When the first video is 115200
The second video is 38400

Send me your configuration again please, with the current settings in slow version.

Can I also check your touchscreen design? I haven't found anything so far...
What happens when you press the buttons on the touchscreen - are you sending them to PC? Is the board receiving any kind of messages from PC?

I'm also sending you two firmware binaries from latest commit on master - just to confirm that this is (or isn't) baudrate issue. One is compiled for 38400 and the other for 115200. Once you load the one with 115200 you need to change it on the screen again.

yes

I see in your design that you are using page <n> command to switch between pages. You can't use that since then firmware doesn't know which page is active. Also because of this, the icon changing cannot work due to this check in firmware:

 if ((_activeScreenID != icon.onScreen) && (_activeScreenID != icon.offScreen))
        return;    //don't allow setting icon on wrong screen

_activeScreenID is set to 1 the entire time since as far as the firmware is concerned, the page is never actually "switched" since there is no information on that. You need to assign printh 65... command for Touch Press event and then mark that button in the interface as page switching button (and also set the correct index of the page that is being switched to).

---

There is another, simpler alternative in that you can have only three pages in total:

0: logo
1: all icons in off state
2: all icons in on state

This requires you to redesign slightly.

Set the page 1 as the initial state, get rid of all "Button" objects and replace them all with "Hotspot" objects.

Actually second option won't work since you need 64 buttons, ignore this then.

Let's redesign
thank you ^^
