Question: ReSpeakerLED.c file modification for more LESs #16

jabulonboaz · 2018-05-05T16:07:25Z

Hello Dimeiza

For the respeker 2 mic hat, where in your code can i change the number of LEDs from 3 to 9 please?
I am using a Respeaker 2 mic hat and I have added a strip of 9 additional APA102 LEDs but only 3 of them light up (3 on the Respeaker board and 3 on my LED strip). I tested the LED strip it works for sure.

I tried to modify your code like this but i cant make all 9 LEDs to light up.
Please refer to the line bellow uint8_t led_rgb_data_2Mic[8][12] = {

I don't know about additional LEDs, but maybe it is caused LED control data haven't been transmitted completely because an array size is small.

If you modify "led_rgb_data_2Mic[8][12]" to "led_rgb_data_2Mic[8][36], it may work well.

jabulonboaz · 2018-05-19T18:09:30Z

I tried it did not work. Any other suggestions please?

Dimeiza · 2018-05-20T00:07:56Z

Unfortunately, I can't give any advice for your customized device.

Why don't you ask Seeed?

jabulonboaz · 2018-05-20T13:14:22Z

Sure i can ask them but i though to ask you first as the code has your copyright. "Copyright 2018 dimeiza. All Rights Reserved." So since you wrote the code i thought you would know which variable to change to increase the LED number.
So far i have only found seed's code for Google Assistant LED patern and i am using that "pixel.py" and it has a variable LEDNUM so i change that and it works. But to create Alexa LED patern i am using your code.
