[SOLVED] Only TX led is blinking, ERR and RX led are alway on



  • I am using v2.0.0 in Arduino ide 1.6.5 and RFM69 radios.
    I am running MockMySensors example on the node and have the following defines:

    #define MY_LEDS_BLINKING_FEATURE
    #define MY_DEFAULT_ERR_LED_PIN 5  
    #define MY_DEFAULT_RX_LED_PIN    6  
    #define MY_DEFAULT_TX_LED_PIN    7 
    
    #include <MySensors.h>  
    

    In the terminal of the node I see these ok messages:

    #########################
    RandomNumber:58

    TSP:MSG:SEND 254-254-0-0 s=255,c=3,t=0,pt=1,l=1,sg=0,ft=0,st=ok:58

    #########################
    

    MY_DEFAULT_ERR_LED_PIN and MY_DEFAULT_RX_LED_PIN are always on and only MY_DEFAULT_TX_LED_PIN is blinking.

    Is this normal behaviour?

    @gvorster could it be that the leds that are always on are connected inverted wrt the one that's working?
    What hardware are you using and how are the leds connected?

    I tested a blink sketch on all 3 pins and they are working.
    Also when I switch the pins to:

    #define MY_DEFAULT_ERR_LED_PIN 6 
    #define MY_DEFAULT_RX_LED_PIN    7 
    #define MY_DEFAULT_TX_LED_PIN    5
    
    or
    
    #define MY_DEFAULT_ERR_LED_PIN 5  
    #define MY_DEFAULT_RX_LED_PIN    7  
    #define MY_DEFAULT_TX_LED_PIN    6
    

    still only TX is blinking and other leds are always on.

    However I'm using a bare ATMEGA328P in QFP package running on the Arduino Pro Mini 3.3v 8mhz bootloader on a diy pcb board.

    I will try it later today on a Nano on breadboard.



  • How are the leds connected to the arduino? Are the LEDs connected to ground or 5V?

    Ah, sorry my bad. That's it. I had it turned around.
    Should have rtfm:

    "Each LED is connected by its anode (long leg) to +5V. The cathode (short leg) is connected through a resistor to one of the following digital pins of the Arduino:"

    Yes that's it I had it turned around.

    @gvorster That's why I asked 😉
    Well, good to hear you solved it 👍
