The following photographs show an Arduino Uno, the Arduino shield kit, 30m LPF kit, and the three different synthesiser kits plugged in: from left to right: Si5351A Synth kit, AD9850 DDS module, OCXO/Si5351A Synth kit.ĬLICK HERE for Demo CW/QRSS/DFCW/FSKCW beacon transmitter sketch, designed to be used with an Si5351A module (standard Synth kit or OCXO version) and LPF kit appropriate to the band being used. Right: Kit contents (note, FT37-43 toroid is included in the kit but missing in the photo!) Middle: Arduino shield kit bag as delivered Left: top row, left to right: LPF kit, OCXO/Si5351A kit, Si5351A Synth kit, AD9850 DDS module. The photographs below (click for larger size gallery) show: The reason for this, is to provide space to optionally accomodate the Relay-switched LPF kit if required.ĬLICK HERE for French Translation of the assembly instructions, by Gilles F1BFU - many thanks Gilles! Kit photographs Note that this Adruino shield kit PCB is slightly larger than a standard Arduino Uno PCB.

Assembly instructionsĬLICK HERE to download the assembly instructions for the kit. People requiring a complete ready-made solution for WSPR or other modes should consider purchasing the Ultimate3S kit instead. If you have written a sketch for Arduino then please email us with details, and it can be added to this page! Many of these have been submitted by constructors. Some example Arduino sketches are provided below. QRP Labs does not provide any complete working sketch for any particular project requirement.
#ARDUINO SIMPLESYNTH SKETCH CODE#
This Arduino shield kit is intended for constructors who wish to experiment with writing their own code to control QRP Labs kits and modules. A GPS receiver module such as the QLG1 is connected to provide precise timing, and location information for WSPR. Si5351A Synthesiser module and LPF kits are plugged into the Arduino shield. In this example, the "Ultimate Arduino shield" is plugged onto the Arduino Uno.
All green-shaded modules are QRP Labs kits. This diagram (RIGHT) shows a typical application, a QRP WSPR transmitter. It can also be used with the QLG1 GPS receiver module kit (or others), and popular AD9850 DDS modules. It is compatible with the QRP Labs LPF kit, QRP Labs Si5351A module kit, QRP Labs OCXO/Si5351A module kit, and QRP Labs relay-switched LPF kit. The kit contains PCB, Arduino headers for connection to an Arduino Uno, Reset button, 4-way headers for plugging in an LPF module, two 10-way headers for plugging in a frequency synthesiser module, necessary components for a QRP power amplifier (around 1/4 Watt on 30m band varies depending on band), and BNC connector for RF output.Īn Arduino board and additional plug-in modules should be purchased as required for your intended application. This kit is an Arduino shield kit only (additional items are shown in some of the photographs, to illustrate possible applications).
#ARDUINO SIMPLESYNTH SKETCH GENERATOR#
Clock generator (3 independent outputs, using Si5351A module kit) Signal generator (using Si5351A module or AD9850 DDS module) As an example, we will create a simple function to multiply two numbers.This is a versatile Arduino shield kit, which could be used in a variety of ways, for example: Other functions must be created outside the brackets of those two functions. There are two required functions in an Arduino sketch, setup() and loop().
They make it easier to reuse code in other programs by making it more modular, and as a nice side effect, using functions also often makes the code more readable. This also reduces chances for errors in modification, if the code needs to be changed.įunctions make the whole sketch smaller and more compact because sections of code are reused many times. Often this helps to conceptualize the program.įunctions codify one action in one place so that the function only has to be thought out and debugged once. Standardizing code fragments into functions has several advantages:įunctions help the programmer stay organized. The typical case for creating a function is when one needs to perform the same action multiple times in a program.įor programmers accustomed to using BASIC, functions in Arduino provide (and extend) the utility of using subroutines (GOSUB in BASIC). Segmenting code into functions allows a programmer to create modular pieces of code that perform a defined task and then return to the area of code from which the function was "called".
