Hey guys,
I gues i have an simple question ,
Is it normal that RS485 on Hardware Serial only works with MY_DEBUG enabled?
If i exclude the MY_DEBUG, communication stops to the gateway
Here an example sketch:
#define MY_DEBUG
#define MY_RS485
#define MY_RS485_DE_PIN 2
#define MY_RS485_BAUD_RATE 19200
#define MY_RS485_HWSERIAL Serial
#define MY_NODE_ID 5
#include <MySensors.h>
#include <DallasTemperature.h>
#include <OneWire.h>
#define COMPARE_TEMP 0 // Send temperature only if changed? 1 = Yes 0 = No
#define ONE_WIRE_BUS A1 // Pin where dallase sensor is connected
#define MAX_ATTACHED_DS18B20 2
unsigned long SLEEP_TIME = 30000; // Sleep time between reads (in milliseconds)
OneWire oneWire(ONE_WIRE_BUS); // Setup a oneWire instance to communicate with any OneWire devices (not just Maxim/Dallas temperature ICs)
DallasTemperature sensors(&oneWire); // Pass the oneWire reference to Dallas Temperature.
float lastTemperature[MAX_ATTACHED_DS18B20];
int numSensors=0;
bool receivedConfig = false;
bool metric = true;
// Initialize temperature message
MyMessage msga(0,V_TEMP);
#define CHILD_ID_LIGHT 25
#define LIGHT_SENSOR_ANALOG_PIN 0
MyMessage msg(CHILD_ID_LIGHT, V_TEXT);
int lastLightLevel;
void before()
{
// Startup up the OneWire library
sensors.begin();
}
void setup()
{
// requestTemperatures() will not block current thread
sensors.setWaitForConversion(false);
}
void presentation()
{
// Send the sketch version information to the gateway and Controller
sendSketchInfo("Node 5", "1.0");
// Register all sensors to gateway (they will be created as child devices)
present(CHILD_ID_LIGHT, S_BINARY);
numSensors = sensors.getDeviceCount();
// Present all sensors to controller
for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {
present(i, S_TEMP);
}
}
void loop()
{
sensors.requestTemperatures();
// query conversion time and sleep until conversion completed
int16_t conversionTime = sensors.millisToWaitForConversion(sensors.getResolution());
// sleep() call can be replaced by wait() call if node need to process incoming messages (or if node is repeater)
wait(conversionTime);
// Read temperatures and send them to controller
for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {
// Fetch and round temperature to one decimal
float temperature = static_cast<float>(static_cast<int>((getControllerConfig().isMetric?sensors.getTempCByIndex(i):sensors.getTempFByIndex(i)) * 10.)) / 10.;
// Only send data if temperature has changed and no error
#if COMPARE_TEMP == 1
if (lastTemperature[i] != temperature && temperature != -127.00 && temperature != 85.00) {
#else
if (temperature != -127.00 && temperature != 85.00) {
#endif
int16_t lightLevel = (1023-analogRead(LIGHT_SENSOR_ANALOG_PIN))/10.23;
send(msg.set(lightLevel));
// Send in the new temperature
send(msga.setSensor(i).set(temperature,1));
// Save new temperatures for next compare
lastTemperature[i]=temperature;
}
}
wait(SLEEP_TIME);
}
Finnaly it is working as it should do!
. The sketch was working after i have deleted the Serial.begin in the void setup.
