RE: Multiple interuppts: One Arduino with two door sensors?
@hek The TP4056 is the charger module. I didn't know you meant the fuel gauge. They are two separate boards which I solder together to one part.

RE: Multiple interuppts: One Arduino with two door sensors?
@hek They are great and very cheap. Just make sure you get the latest version of the board (the one with the micro-usb). 10pcs for $7 on Ebay.

RE: Multiple interuppts: One Arduino with two door sensors?
I found this example file to work much better. The battery drained a lot slower.

RE: Raspberry Pi Ethernet Gateway
Tried EasyIoT server @ericvdb? Not my project, but I'm using it now. Simple to set up and use. Just make sure that you use the correct channel for your server and your nodes. Default is set to 95.

RE: Multiple interuppts: One Arduino with two door sensors?
@BulldogLowell Thank you! It finally works! I'll make a sketch with comments so other people can use it later for reference.

RE: Multiple interuppts: One Arduino with two door sensors?
@BulldogLowell said:
MyMessage msg(0,V_TRIPPED);
So I need to call MyMessage twice. one for each sensor ID? How do I do that without making two instances? That is kind of what I have been trying to do, but I'm having trouble with the syntax.
-
RE: Multiple interuppts: One Arduino with two door sensors?
The problem remains @BulldogLowell . It's like the arduino is treating the two interrupts as one.
The sensors react when trigger them, but it's only N2S1 (door) that shows up in my gateway (EasyIoT), and it always displays the same value (closed). I'm going to go over the wiring and the code again.
Reading one sensor connected to one interrupt is simple... reading two seems impossible
Here's the current state of the sketch:
// Simple binary switch example //USING TWO INTERRUPTS // #include <MySensor.h> #include <SPI.h> #include <Bounce2.h> // For lipo gauge #include "Arduino.h" #include "Wire.h" #include "MAX1704.h" // #define DOOR_PIN 3 // Arduino Digital I/O pin for button/reed switch #define MAILBOX_PIN 2 // MAX1704 fuelGauge; int oldBatteryPcnt = 0; // MySensor gw; Bounce debouncer[2]; byte oldValue[2] = { -1, -1}; // unsigned long sleepTime = 86400000UL; // 1 day // Change to V_LIGHT if you use S_LIGHT in presentation below MyMessage msg(0,V_TRIPPED); // void setup() { // Fuel gauge fuelGauge.reset(); // GW gw.begin(); debouncer[0] = Bounce(); debouncer[1] = Bounce(); // Setup the buttons and Activate internal pull-ups pinMode(DOOR_PIN,INPUT_PULLUP); pinMode(MAILBOX_PIN, INPUT_PULLUP); // debouncer[0].attach(DOOR_PIN); debouncer[1].attach(MAILBOX_PIN); debouncer[0].interval(5); debouncer[1].interval(5); // gw.present(DOOR_PIN - 2, S_DOOR); delay(250); gw.present(MAILBOX_PIN - 2, S_DOOR); } // void loop() { // Fuel gauge int batteryPcnt = fuelGauge.stateOfCharge(); if (oldBatteryPcnt != batteryPcnt) { gw.sendBatteryLevel(batteryPcnt); oldBatteryPcnt = batteryPcnt; } // for (byte i = 0; i < 2; i++) { debouncer[i].update(); int value = debouncer[i].read(); if (value != oldValue[i]); gw.send(msg.setSensor(i).set(value == HIGH? 1 : 0), false); oldValue[i] = value; } gw.sleep(DOOR_PIN - 2, CHANGE, MAILBOX_PIN - 2, CHANGE, sleepTime); }

RE: Multiple interuppts: One Arduino with two door sensors?
Thanks again @BulldogLowell
I think I'm going a bit crazy over this. The problem remains. Only the data for the door is being sent (it only sends closed), but not for the mailbox. Is it because I am defining only the door in the code below?
MyMessage msg(DOOR_PIN,V_TRIPPED);
-
RE: Multiple interuppts: One Arduino with two door sensors?
Thanks @BulldogLowell for all your help! The interrupts are working now, but there is something wrong with the MyMessage function.
MyMessage msg(DOOR_PIN,V_TRIPPED);
Correct me if I am wrong, but it seems like we only instantiate it for the DOOR_PIN, but not for the MAILBOX_PIN. I tried a solution similar to how you instantiate the the bounce functions, but for some reason it does not work.
What happens now is only one message gets sent (for the door). And it's also saying that it is always closed.
gw.send(msg.setSensor(i).set(value == HIGH? 1 : 0), false);
I can see here that you use the setSensor method to the pin numbers 0 and 1 (interrupt pins?). But shouldn't it use the pins that we declare at the top?
#define DOOR_PIN 3 // Arduino Digital I/O pin for button/reed switch #define MAILBOX_PIN 2

Thank you @hek! I will try and solve it now, and then show my sketch here later.

RE: Multiple interuppts: One Arduino with two door sensors?
Thanks for the help @BulldogLowell!
I read your code, and I can see that you are setting the variables smarter than I. However, I can't seem to understand where you put the interrupts. Is the sensor going to sleep?
The actual button/triggers were not the problem. It was how to set up the interrupts.

RE: Multiple interuppts: One Arduino with two door sensors?
@ericvdb It's a USB charger board (TP4056). The battery is connected to it via a MAX17043 LiPo Fuel Gauge which is soldered directoly onto the usb charger board.

Multiple interuppts: One Arduino with two door sensors?
I've been looking around the forum for a solution, but haven't found one. I have one arduino and two door/window sensors. One sensor will be on my apartments front door, while the other sensor will sit on the mailbox-slot.
The problem is that I don't know how to get two interrupts running at the same time. So if the door opens, one interrupt should trigger. And if I get mail (and the slot opens) the second interrupt should trigger.
I'm using an arduino pro mini 328p.
Here's my code:
#include <MySensor.h> #include <SPI.h> #include <Bounce2.h> #define CHILD_ID_DOOR 0 #define CHILD_ID_MAIL 1 #define DOOR_PIN 2 // Arduino Digital I/O pin for button/reed switch #define MAIL_PIN 3 // Arduino Digital I/O pin for button/reed switch #define INTERRUPT DOOR_PIN-2 #define INTERRUPTMAIL_PIN-3 // For lipo gauge #include "Arduino.h" #include "Wire.h" #include "MAX1704.h" MAX1704 fuelGauge; int oldBatteryPcnt = 0; unsigned long SLEEP_TIME = 86400000; // 1 day MySensor gw; Bounce debouncer_door = Bounce(); Bounce debouncer_mail = Bounce(); int oldValue_door = -1; int oldValue_mail = -1; // Change to V_LIGHT if you use S_LIGHT in presentation below MyMessage msgDoor(CHILD_ID_DOOR,V_TRIPPED); MyMessage msgMail(CHILD_ID_MAIL,V_TRIPPED); void setup() { // Fuel gague fuelGauge.reset(); fuelGauge.quickStart(); fuelGauge.showConfig(); gw.begin(); // Setup the button pinMode(DOOR_PIN,INPUT); // Activate internal pull-up digitalWrite(DOOR_PIN,HIGH); pinMode(MAIL_PIN,INPUT); // Activate internal pull-up digitalWrite(MAIL_PIN,HIGH); // After setting up the button, setup debouncer debouncer_door.attach(DOOR_PIN); debouncer_door.interval(5); debouncer_mail.attach(DOOR_PIN); debouncer_mail.interval(5); // Register binary input sensor to gw (they will be created as child devices) // You can use S_DOOR, S_MOTION or S_LIGHT here depending on your usage. // If S_LIGHT is used, remember to update variable type you send in. See "msg" above. gw.present(CHILD_ID_DOOR, S_DOOR); gw.present(CHILD_ID_MAIL, S_DOOR); } // Check if digital input has changed and send in new value void loop() { // Fuel gauge int batteryPcnt = fuelGauge.stateOfCharge(); if (oldBatteryPcnt != batteryPcnt) { // Power up radio after sleep gw.sendBatteryLevel(batteryPcnt); oldBatteryPcnt = batteryPcnt; } // Door debouncer_door.update(); // Get the update value int value_door = debouncer_door.read(); if (value_door != oldValue_door) { // Send in the new value gw.send(msgDoor.set(value_door==HIGH ? 1 : 0)); oldValue_door = value_door; } // Mail debouncer_mail.update(); // Get the update value int value_mail = debouncer_mail.read(); if (value_mail != oldValue_mail) { // Send in the new value gw.send(msgMail.set(value_mail==HIGH ? 1 : 0)); oldValue_mail = value_mail; } gw.sleep(INTERRUPT,CHANGE, SLEEP_TIME); }
