Hello Guys, i've got this new groove led strip driver wich as the name suggests drives an led strip (4pin 12v led strip). I tested it with my Arduino uno and the recomended code of the website and it works fine. Now I want to control my led strip wirelessly so i bought an esp32. When I tried the same code (I changed the pins obviously) with it, the led's don't work anymore and just blink in random colors at random intervalls. I think this has to do with the driver and the esp32 not beeing in sync with one another but I dont now. Thanks for any advice, you can find my code below
DemoLedStrip.ino
#include "RGBdriver.h"
#define CLK 18//pins definitions for the driver
#define DIO 19
RGBdriver Driver(CLK,DIO);
void setup()
{
}
void loop()
{
unsigned int i;
while(1){
for(i = 0;i < 256;i ++)
{
Driver.begin(); // begin
Driver.SetColor(i,i,i); //Green. First node data. SetColor(B,R,G)
Driver.end();
delay(10);
}
delay(10000);
for(i = 255;i > 0;i --)
{
Driver.begin(); // begin
Driver.SetColor(i,i,i); //Green. first node data
Driver.end();
delay(10);
}
}
}
