Re: Question about Nextion display and firmware
Hello Bo, Many thanks for your responds, and yes, the proc is 2560, I will be very happy if you send me Hex file, I have just some questions about input/output pins for identify differents functions. vY¡¯s 73s de Jacques ¨C F1APY

Subject: Re: [BITX20] Question about Nextion display and firmware? I don't think the source files for the latest CEC firmware have been released yet. I may still have an earlier version.
I think the chip you mentioned is a mega2560. If so I could send a hex file of the previous version compiled for the 2560.

Re: ND6T AGC and Click kit wiring notes
Quick questions... to add rf gain I just wire the VR to the AGC board? And how do I wire an AGC fast and slow switch?
Thanks,

Re: uBitx Version 3 and my homebrewed enclosure complete - Well Almost!!

As you have the AVC kit installed, you canuse it for the S-meter and forget about using another chip and such .
Just hook the ubitx? s-meter wire to the AVC board.? It goes to the first pin where the jumper is on the board that sets the delay.? I forget the capacitor number, but it goes on that junction and the resistors for the time delay .
Works fine after you set up the values using the memory manager.

Looks nice!? What case are you using?? May I ask the current draw on receive?

Jack and rest if bit20 group I was 1/2 wrong!
Pull-up resistorsThe analog pins also have pull-up resistors, which work identically to pull-up resistors on the digital pins. They are enabled by issuing a command such as:
pinMode(A0, INPUT_PULLUP); // set pull-up on analog pin 0
Be aware however that turning on a pull-up will affect the values reported by analogRead().
***? It is the last line that may cause issues.? Guess if you define a "iINPUT_PULLUP" then you should not use analogRead().

I didn't know that. Since all of the Nano pins, including the analog pins, can be used as digital pins, I thought they, too, would have pullups that could be turned on. Is that not the case?
