Were changed to be able to test the PlatformIO feature to compile only files that are actually used.
Apparently the Arduino IDE cannot find the files anymore because that IDE needs the parent directory to be named as the main project file, not "src"
* [SDS011] Add send commands to sensor
In the library used to communicate to the SDS011 sensor was only support to receive data from the sensor and not query the sensor or set another mode.
This is needed for #499 , to let the sensor sleep.
N.B. code is not yet tested, only implemented while reading the datasheet "Laser Dust Sensor Control Protocol V1.3"
* [SDS011] Lessen load on ESP by polling less frequent and use SoftSerial
The default setting were to set the delay to 0 and use an own software serial implementation.
This caused frequent timeouts on the web interface, WiFi reconnects, etc.
Now the already present SoftSerial is being used. This will gather all the data from the serial port and thus there is no need to poll 50 times a second.
Now the ESP is much more responsive.
* [SDS011] Allow the sensor to sleep to extend sensor lifetime
The internal laser of the SDS011 only will last for about 1 year when ran continuously.
When the RX of the sensor is connected, it can be set to sleep for N minutes between measurements. This will extend the lifetime of the sensor and reduce power consumption.
This sleep time is stored inside the flash of the sensor, so it can be set once and then the RX on the sensor could be disconnected again to be used for other purposes.
* [addLib] Added SoftwareSerial library
Added latest version from: https://github.com/plerup/espsoftwareserial
* [renLib] Renamed files to avoid conflicts with existing code
* [renLib] Changed include according to rename
* [renLib] Renamed all occurences and includes and removed unused pins
Renamed to make sure all plugins use the 'new' ESPeasySoftwareSerial.
Also added pinToIndex function to reduce memory footprint with about 150 Bytes, as described in issue #630
* [unused pins] Adjust indices in object list
Forgot to change the indices in the object list of SoftwareSerial
* Simple patch for timeouts
As mentioned in this issue: https://github.com/plerup/espsoftwareserial/issues/54
* [SoftSerial] Set ObjList static
Set the object list static to share all SoftwareSerial iRAM used as described in #630
* [revertLib] Revert to old version lib, since new version uses more iram
Just to test with old version, originally available in 2.3.0 library, to see if memory usage improves.
* [test] Reduce number of ports to 1 and lower buffer size to 18 for MHZ19
Just as a test, to see what happens to the iRAM usage, lower the number of concurrent softserial ports to 1.
Also the default buffer size = 64 Bytes. The MH-Z19 sensor can do with less, since a response will be up to 9 bytes, a 18-byte buffer allows for 2 messages to be stored.
* Enable usage of up to 10 concurrent softserial and reduce variable sizes
Re-enable use of up to 10 concurrent software serials.
Also reduce the variable sizes to smaller ranges. (e.g. uint8 instead of int)
* [test] Limit number of concurrent software serial devices
Earlier tests show the amount of iRAM used is somewhat related to the maximum number of allowed software serial ports.
In this test it is set to 3 and they are assigned through first come first served a slot.
