Turn on flash every capture

[ricardo-brenner]

How can I enable the front led to each frame that is captured?

You want to turn on the Blinding Disk-Active Light? It's blinding!

In function codeForCameraTask(), line 354 in v89, add the lines below. The do_blink() function blinks it on slightly and briefly -- I'm not sure if that is currently used -- but if you want full power for a flash-photo, you can add these lines.

The picture is taken with the fb_get() -- you might have to delay for a couple milli-seconds for the led to turn on between the digitalwrite and the fb_get ???

pinMode(4, OUTPUT);               // Blinding Disk-Active Light
digitalWrite(4, HIGH);             // turn ON

delay(1);  // delay to turn on the gpio, the transistor, and the LED ???

 bp = millis();
 fb_q[fb_in] = esp_camera_fb_get();
 totalp = totalp - bp + millis();

pinMode(4, OUTPUT);               // Blinding Disk-Active Light
digitalWrite(4, LOW);             // turn OFF

That's exactly what I needed, worked like a charm.
