Hardware Timer didnt work https://github.com/khoih-prog/ESP8266TimerInterrupt#why-using-isr-based-hardware-timer-interrupt-is-better

=> Software Timer https://ullisroboterseite.de/esp8266-timing.html#timer

Zum aktivieren von GDBStub:

#include <GDBStub.h>

...

void setup() {
  Serial.begin(460800);
  gdbstub_init();

Achtung !

GDB muss dafür compiled werden GDB-Version aus Arduino Toolchain hat Support

$ ./start_xtensa_gdb_stub.sh

Achtung !

Don`t forget \r

ESP-OTA wird von ufw oder Defender geblockt.

• Windows -> Python needs to be granted with rights
• Linux -> open udp port in ufw ->

platform.ini 
upload_flags =
  --host-port <PORT>
...
$ sudo ufw allow tcp/<PORT>

server.streamFile(f, mime::getContentType(SRH::_path), requestMethod);

=====>

const String& p = SRH::_path;
if(p.endsWith(".gzip")) {
    server.sendHeader("Content-Encoding", "gzip");
    server.streamFile(f, mime::getContentType(p.substring(0, p.length()-5)), requestMethod);
}
else
    server.streamFile(f, mime::getContentType(SRH::_path), requestMethod);

HW issues

• GPIO2 used as input -> must be high during startup
• PCB Solution: cut trace to GPIO2, solder bridge to GPIO16
• -> disadvantage: GPIO16 is not interrupt capable

FSM 2 - to do

• stairway light switches off after timeout
• switches concurrently on again if sensor is still high
• desired behavior? Defective Sensor would cause continuos animation
• edge detection / interrupts as solution ?

LED_sequence_v1:

TODO:

• disable led stripes after defined time (webserver paramter?)
• define what to do if people enter stairs from different directions
• CAUTION: Sensor-Deadtime at LEAST 8 seconds
• --> switch off with person leaving stairs might not be possible

Webserver on v0.3.0 now working with LittleFS

TODO:

• check dir for files automatic
• move handleNotFound to httpserver.h
• maybe compress files ?

LED Flickering issue

https://github.com/NachtRaveVL/PCA9685-Arduino/issues/15 PlatformIO Library veraltet !!

TIMER in OTA unterbrechen !!!!!

further improvments

with streamFile gzip encoded Files can be sent this reduces space on fs ! new easier script needed to just convert to .gz maybe measure timings on ESP

=> use serveStatic because way simpler ! => serverStatic(“/”) works wonders

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAARHRRHRGH Two implementations of FSM are not that good, linker puts them together ?!? :):):):):):):) => maybe investigate for doc

TODO Treppe

• dynamic lighting with ldr
• http control over active pwm … => set_active_pwm() -> is implemntiert, kann mit % oder abs eingestellt werden
• testing if dimming crashes when two animations -> ldr does not interrupt animation, animation get’s finished and stairs fade out -> FSM works without collisions
• interrupt to pending from sensors -> rising edge trigger implemented, via pending input
• settings struct -> implemented with EEPROM -> adapted to only change on ruhezustand
• script for gdb on windows -> implemented
• welcome animation ? -> wird hochgedimmt beim einschalten von 0
• on/off switch http

• use logging to serial http monitor with httpserver.logt() -> is used for some status updates

• behavior when someone enters stairway from opposite direction while animation is running? -> currently ignored, second persons walks in darkness -> animation from both sides? -> problem: person 1 leaving stairway might pass the sensor right after person 2 -> person 1 leaving not detected

• behavior when someone enters stairway from opposite direction after animation finished but person 1 is still on stairway? -> currently stairs fade off from direction 1 -> additional wait-state between “warten hoch/runter” and “abdimmen hoch/runter” after sensor detected person?

• active brightness can be lower than idle in the moment

• change idle to precentage of active !!!
