#20515

Hi All,

I am having ANOTHER senior moment :-((.? I finished my Arduino Shield Rev.2, but I can not for the life of me figure out how to interface with it to be sure that everything is setup correctly (like the LCD screen on the U3/U3S).? There are no directions or programming setup (that I can find), as there are in the U3/U3S ops manual.

I am using Hans Summer's sketch "demonstration, a simple QRSS/DFCW/CW/FSKCW beacon QRP transmitter using Si5351a synthesiser".? Not being that? familiar with Arduino, I am assuming that some of the values will be set in the program depending on what freq, mode, etc.?

Anybody using the Arduino Shield give me a hand to get up and running, or a reference to get some direction?

Thanks,

Kent, KC9LIF

I $do not$ have that shield but am considered by many to be dangerous around Arduini.?

The shield instructions say that it is $not$ a complete solution for anything.?

If you have not already, download the IDE??. I have never had success using the web version and I’m sure others have had no success using the downloaded IDE. Close cover before striking.?

You will need to connect your computer — the IDE supports Windows, Linux, and Mac — to the shield with a USB cable.?

If you need further tutelage, in the event nobody else with better info chimes in, reply here and we can probably work it out on the phone.?

That demo program does not seem to write to a display.? You change the parameters where it says "Edit ......" and it will run whatever mode you have set.? To change modes, you would edit the section again, recompile and reload the program.

That said,? if you want to add a display you would look at the schematic for the arduino shield and pick some pins that are not used or pins that could be shared.?? Since the arduino I/O is passed straight through the shield, if you can get a display to work with just the arduino and display, it will work with the shield in between.?

I am currently working on a project and plan to hook my display up with the 4 data lines on pins 10,11,12,13 and use pins 7 and 8 for the control lines.? I am not using the relay switched low pass filter board, so the I/O lines labeled band0 to band5 are free for my project.

So I think your first step is to get your display to work with arduino.? Then add the shield.

Kent,

I've used that sketch recently, but not with an Arduino Shield. It's a straightforward demo that works, though.

As far as required software changes, you'll find them in this section of the code:

#define Message "CALLSIGN "              // Your callsign (or message) here! Remember to put a space at the end!
#define Frequency 10000000               // Transmission frequency, in Hz
#define Fsk 5                            // FSK amount for FKSCW and DFCW, in Hz
#define Mode MODE_QRSS                   // Transmission mode: MODE_QRSS is used for QRSS or CW
#define Speed 0                          // Dit speed: 0, 1, 2, 3 index into the speeds[] array, see below. 0 is 12wpm CW
#define XTAL_FREQ 27000000               // Crystal frequency for Si5351A board - needs to be adjusted specific to your board's crystal

Edit the first two lines to set your callsign and transmit frequency.? For an initial test, leave everything else as is, as long as your crystal is 27MHz.? The program will send standard 12wpm cw at the assigned frequency -- or at least it did so for me. Monitor on an external receiver.

At this point, I don't have an assembled shield, so I can't help much with the hardware.? There are some jumpers required on the shield.? Be sure to place a dummy load (47-51 ohm resistor) across the RF output.? You might consider leaving the final amp (BS170) unpowered for initial testing.

72,
Michael? KD4SGN

Thanks to Jim, Ron, and Michael,? for your very helpful suggestions.?? I am going to get my display going as you suggest, Ron, and then attach the Shield, and make the software changes as suggested by all.? I have a dummy load on the antenna, so I will be able to monitor to one of my radios, when I activate the shield.? That? should get me going into the right direction.? Very FB, Guys!
