A while ago, MySensors changed to use int32_t instead of long int (and similar for other data types). This change was not applied to all examples, causing some examples to fail compilation for ESP8266 with the following message: call of overloaded 'set(long int)' is ambiguous This update changes the casts to match the new style. This fixes https://github.com/mysensors/MySensors/issues/1129 Thanks to https://github.com/henfri for reporting.

* The MySensors Arduino library handles the wireless radio link and protocol

|
* between your home built sensors/actuators and HA controller of choice.
|
|
* The sensors forms a self healing radio network with optional repeaters. Each
|
|
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
|
|
* network topology allowing messages to be routed to nodes.

* DESCRIPTION
|
|
*
|
|
* Dust Sensor for SamYoung DSM501
|
|
* connect the sensor as follows :
|
|
* Pin 2 of dust sensor PM1 -> Digital 3 (PMW)
|
|
* Pin 3 of dust sensor -> +5V
|
|
* Pin 4 of dust sensor PM2.5 -> Digital 6 (PWM)
|
|
* Pin 5 of dust sensor -> Ground
|
