I received my MOD54415 today and was running the factory demo. When I go to the LED Example page it shows the switches as being on, but they are in the off position. Below you can see each time I click the Refresh Switches link the serial port reports Switch register 0x00. Then I flip switch 5 to on and I get the trap information and it is locked up. I am using Uart0 on JP4 with external power and JP1, JP2 and JP3 in the 2-3 position. The reset won't return it to operation, only a power cycle.

Is this the dev 70 or dev 100 board?

Well, not saying that it's not a problem, but with the latest internal build I can't reproduce the bug.

It doesn't appear that there's been any fix in the FactoryApp code. Can you tell me what version of the NNDK you're running if you're still having the problem?

The carrier PCB is "MOD-Dev-70", "Rev 1.7". I have not loaded any code to the unit. The only thing I have done so far is set the IP address to a fixed address at 192.168.1.202, using IPSetup V2.1.

The NNDK version would be "NNDK 2.6", but again I have not even put a project into it yet.

I do have another module on the network a MOD5234, at address 192.168.1.201.

I just received MOD54415 and demo works fine.

Mod-Dev79 Rev1.7, MOD54415 Rev 1.5.

Gary, can you try building the app with the NNDK, load it, and try again? If it still fails could you open a support ticket?

In DoSwitches, the code for on and off is reversed. So switches that are off show up as on and vice versa.
The comments are correct, but the siprintf's are wrong:

if ( sw & ( 0x80 >> ( i - 1 ) ) )
{
// Switch is on
siprintf( buffer, "<tr><td>Sw%d</td><td>OFF</td></tr>", i );
}
else
{
// Switch is off
siprintf( buffer, "<tr><td>Sw%d</td><td>ON</td></tr>", i );
}


On my board, the A/D behavior is erratic. With only switch 8 on (enabling the iprintf in ReadSwitch) I see for two runs:
ADC[7] = 7FF8, BitPos: 01, BitMask: 01
ADC[6] = 3DA8, BitPos: 02, BitMask: 01
ADC[5] = 0000, BitPos: 04, BitMask: 01
ADC[3] = 0120, BitPos: 08, BitMask: 01
ADC[4] = 0000, BitPos: 10, BitMask: 01
ADC[1] = 01E8, BitPos: 20, BitMask: 01
ADC[0] = 00C0, BitPos: 40, BitMask: 01
ADC[2] = 0130, BitPos: 80, BitMask: 01
Switch Register: 0x01
ADC[7] = 7FF8, BitPos: 01, BitMask: 01
ADC[6] = 7FF8, BitPos: 02, BitMask: 03
ADC[5] = 0000, BitPos: 04, BitMask: 03
ADC[3] = 0190, BitPos: 08, BitMask: 03
ADC[4] = 0000, BitPos: 10, BitMask: 03
ADC[1] = 01D0, BitPos: 20, BitMask: 03
ADC[0] = 00C8, BitPos: 40, BitMask: 03
ADC[2] = 0200, BitPos: 80, BitMask: 03
Switch Register: 0x03

You are correct about the switches being reversed.

The support guys got my problem corrected. The fix for my lockups was to connect the A/D reference input, you need to connect J2 pin 5 (ADREF) to 3.3V. The closest pin is J2 pin 2. The switches then function correctly.

Ah. Adding the jumper you mention fixed my wandering A/D problem. The switch readout is now solid. Thanks.
