Problem with Wi-node 2.0 and digital Pin 4

[Philomenale]

Hello,

 

I have a Wi-Node 2 with a strange behavior. It's seems to be impossible to use RFM12 and motor driver at same times.

 

When digital pin 4 is configured as output, the "rf12_recvDone()" don't work.

 

For example with the "timedsend" from jeelib available at following adress

https://github.com/jcw/jeelib/tree/master/examples/RF12/timedSend

 

When I had the line pinMode( 4 , OUTPUT); in the setup function, the test rf12_recvDone() always fail.

 

/// @dir timedSend

/// Experiment with time-controlled periodic transmission.

#include "../../LibRF12/JeeLib.h"

 

MilliTimer sendTimer;

byte pending;

word seqnum;

 

void setup () {

  Serial.begin(57600);

  Serial.println("\n[timedSend]");

  rf12_initialize(25, RF12_868MHZ, 4);

  pinMode( 4 , OUTPUT); // <-- This line causes the failure

}

 

void loop () {

  if (rf12_recvDone() && rf12_crc == 0 && rf12_len == 2) {

    sendTimer.set(0);

    Serial.print(" #");

    Serial.print(seqnum);

    Serial.print(" start: ");

    Serial.print(rf12_data[0], DEC);

    Serial.print(" recvd: ");

    Serial.println(rf12_data[1], DEC);

  }

 

  if (sendTimer.poll(2096))

    pending = 1;

 

  if (pending && rf12_canSend()) {

    pending = 0;

    rf12_sendStart(RF12_HDR_ACK, "hello!", 6);

    ++seqnum;

  }

}

 

 

I didn't see anything in the solders...

Have you got any idea ?

Thanks for your help !

Yeah, the pins are messed up and you have to jumper a couple of places. I'll have to check on the one I did just to see. it also depends on which board you have. One will work, the other not.

Hello,

After studying the eagle schematic and board of Winode2 and made several tests with the ohmmetre, I identified the problem:

There is a connection between 2 pins of SD socket !

To solve this:

First I tryed to remove the weld with a solder pump without success.

Then I scratch between the two pins with sharpened blade and that solve the problem.

RFM12 and motor driver could now be used at same times :).

The eagle schematic and board of Winode 2 where vey usefull (linked files).

I didn't found the ones of Winode 4, are they available sommewhere ?
