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:__
|
|
```c
|
|
#include <GDBStub.h>
|
|
|
|
...
|
|
|
|
void setup() {
|
|
Serial.begin(460800);
|
|
gdbstub_init();
|
|
```
|
|
|
|
### __Achtung !__
|
|
GDB muss dafür compiled werden
|
|
GDB-Version aus Arduino Toolchain hat Support
|
|
|
|
```sh
|
|
$ ./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 ->
|
|
|
|
```sh
|
|
platform.ini
|
|
upload_flags =
|
|
--host-port <PORT>
|
|
...
|
|
$ sudo ufw allow tcp/<PORT>
|
|
```
|
|
|
|
|
|
```c++
|
|
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 !__
