@@ -2,7 +2,42 @@ This page lists possible blink codes of the red LED located on the ESP32-CAM boa
The effective error codes can be found [here](https://github.com/jomjol/AI-on-the-edge-device/blob/rolling/code/components/jomjol_helper/statusled.h).
TODO!!!
# General design approach:
* 250ms blink code to identify source
* 500ms defined LED off
* 250ms blink code to identify error / status code
* 1,5s LED off to signal repetition
* e.g. 3x blinks | 500ms LED off | 2x blinks --> error: SD card not found
| **source** | source blink count| error / status | status blink count| repeat infinite |

# Error
Those errors make the normal operation of the device impossible.
