sometimes LED does not turn off when i click turn off

[hans2356]

i am using ambilight kit from alliexpress. the led works fine, but when i click turn off button, the leds changes dim white, and does not response to screen. also, if i shutdown my computer without turn off the leds, they left tuned on.

try setting this to 0

[hans2356]

that fixes dim white problem, but i want to keep eye care setting. and they did not fix the turn off problem when my computer shuted down.

i've got source code from seller, and it seems very similar to https://github.com/dmadison/Adalight-FastLED/blob/master/Arduino/LEDstream_FastLED/LEDstream_FastLED.ino#L221 i think there is timeout option for controller, but i can not upload it to my board somehow..

my sketch says avrdude: Version 6.3-20190619 Copyright (c) 2000-2005 Brian Dean, http://www.bdmicro.com/ Copyright (c) 2007-2014 Joerg Wunsch

avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xf8

and this is code from seller LEDstream_FastLED.ino.txt.txt

Is there possible to make plugin that automatically turn off the leds when program off or computer shutted down?

hi, could you try this one: https://github.com/dmadison/Adalight-FastLED it's an updated version of the one you linked and have a timeout in case of no communication. by default it's 60s but you can change it:

const uint16_t
    SerialTimeout  = 60;      // time before LEDs are shut off if no data (in seconds), 0 to disable

[hans2356]

unfortunately, my uno can't reprograming. it seems not reprogramable. so, i made some macro using autohotkey which automatically change the profile that turn off all led when i shut down.

[Ekristoffe]

Weird, never saw a Uno which can't be reprogrammed. What does the error say ? Have you exit the ambilight software before trying to reprogram it ?

i am using arduino ide 2.0.0 and using same useb port the product use(ch340) when i click upload button, they says avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x13 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x13 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x13 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x13 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x13 Problem uploading to board. See https://support.arduino.cc/hc/en-us/sections/360003198300 for suggestions.

and the seller says, this product can't be rewritten. so i made some macro using #306 they let profile changed (luminosity threshold 0, overall brightness 0%) before the system shutdown.

[Ekristoffe]

Interesting. Do you have a brand / model name ? Maybe this is why arduino chip can be found online for cheap.

[hans2356]

i don't have it right now, but i will ask to seller, and after they answer, I'll post here

could be SPIEN fuse bit

SPIEN: 0 value (programmed) means serial programming of ATmega32/32A enabled. Don’t change this unless you have parallel programmer! Because once disabled ATmega32A can’t be programmed using serial programmer.
