Actually, once you fix the broken line, the code should work. However, let's make sure the Nano is getting the compiled code. Try this:

Load the Arduino IDE

Plug the USB connector into the Nano

Check to make sure the Arduino Nano is selected (Tools --> Board)

Check to make sure a COM port is assigned to the Nano (Tools --> Port)

??? These last 2 steps must be set to go any further

Load the Blink program (File --> Examples -->01.Basics --> Blink)

Compile/upload Blink sketch

If you can do this and the Nano red LED blinks in a 1 second rhythm, you know your Nano is good. Assuming that all is well, then try:

Load the LCD Hello World program (File --> Examples --> LiquidCrystal --> Hello World). Note that this program may be pretty far down the list.

Compile/upload the Hello World sketch.

If this works, then I don't know why the Bitx code doesn't work. If this does not work, then start looking for some kind of wiring/connection error between the Bitx board and the Raduino board.

Jack,

Have load the software up but can’t see anything on display.

I checked the hardware and found ?a broken line (no voltage 3,3volt on si5361a).

Surely I have to reload the software and see what happens.??

The red LED should not blink any more since you have replaced the Blink program with the Bitx program. Which software are you trying to load? I would suggest using the original Raduino software for the first try, as it requires no modifications to the system.

Doug,

first, I am appreciate your help very much.

now we repeat the procedure on my sons pc (win 10) and the upload was done very well on com 3—

but next problem is that the display shows nothing.

red led on board doesnt blink anymore. Green led is on. Rx/tx led off.

you have any advice .?

Elmar,
None of us were born knowing how to do this.? I will try to explain with more detail to see if we can get you through this.? Let us first see if your computer is recognizing the nano.? This will help determine if you have the correct driver.

First go to your device manager.? In Windows 7 go to control panel, then systems and security, and finally device manager.? Most likely you will have one of the two situations described below.

Find a heading labeled Ports (COM & LPT).? Do you see Arduino Nano listed?? If so, write down the port number shown after it.
If you did find the Nano in that section you have the driver.? Now go to the Arduino IDE (the program you installed to compile and load sketches) and check the following under the Tools tab at the top:? For board make sure it shows Arduino Nano, select it from the list by clicking the arrow.? For port make sure it shows the port number you found in your device manager.? Once you have the board and port selected you should be able to upload the sketch.

If in your device manager the Nano does not show up under ports it is probably under Other Devices.? If that is the case you do need to install the driver.? That is also a relatively easy step but that will be for another post if you need it.

Let us know what you find.
