KD8CEC and S-Meter

V Zecchinelli
 

Good Morning,

I am having difficulty activating the S Meter.  I have it checked in Memory Manager V1.11 and have tried several different number configurations along with S Meter box checked and nothing shows on S Meter.
Memory Manager = V1.11
KD6CEC = V1.2
UbitX = V5

Am I missing something anywhere?  UbitX.h shows "//Select betwen Analog S-Meter and DSP (I2C) Meter
#define USE_I2CSMETER"

Thanks,
Vince

If you're not on I2C, you need to comment this line because you want to use A7 to work with it.

Just to confirm that you did connect the diode, cap and resistor per the KD8CEC directions to measure the audio output at the high connection of the volume control?

FWIW

Thanks Evan.  No, I had not seen this.  I think I found it here http://www.nd6t.com/bitx/S%20meter.htm.  A2 is A2 on the Nano or Pin 2 on the Analog Raduino connector which seems to be Pin 3 for A2 on the Nano?

I am using Nextion so using I2C.  I should have mentioned Nextion in original email.
Thanks,
Vince

Another idea is to install the extra nano (with s meter firmware) and install the _s firmware on the randiuno. The S meter also works a bit faster then.

Vince,

There are 2 versions of the CEC software for each of the display types.  The difference is one uses a seperate I2C connected Nano to add functionality.  The other uses the spare input pin on the Nano to connect the S-Meter. Read the FileNameInfo.txt file to insure that you use the correct one.

The added hardware sensor for the direct connected S-Meter is in this article on the HamsKey web page:

If you add a second Nano then this is the article on how to connect it:

If you go the rout of adding the I2C connected Nano, then there are other functions that can be added beyond the S-Meter.  As Werner suggested.

So the choice is yours.  That is the beauty of the uBitx and the great additions that Dr. Lee (KD8CEC) have provided.

I saw the S meter firmware but wasn't sure what it was about.  Got it.  Thanks.
