    OpenTR6260 - does this support PWM?

    Have purchased a cheap RGB strip - Status is the manufacturer but it appeared to work with Tuya.
    I flashed it with OpenTR6260 however LED control only appears to work using relays/LED at full brightness.

    Here are some images of the controller itself whilst flashing it earlier today.

    I have also found this module does not let me save any configs down now it appears to return to an earlier one I created a few hours ago each time. Very odd, probably looking at a reflash unless there is an ota update?

    I tried PWM on GPIO22, and it works. While "Toggle light" isn't working, changing brightness works ok.

    Regarding config save, what partition file are you using? The most recent one is https://github.com/NonPIayerCharacter/OpenTR6260/blob/master/new_partition_0x6000.bin

    No OTA, since we have no tool to generate one. Updates can only be flashed via UART.

    A quick fix: https://github.com/openshwprojects/OpenBK7231T_App/pull/1838
    With that fix, "Toggle light" works, but leds will still glow a little.
    Plus expanded available PWM pins to include GPIO0-4 and GPIO14-15
