In this circuit, I have paired my Home-Brew Arduino Uno with AD9850 module purchased online from on EBay, a 16X2 LCD display, Rotary encoder, and a few other small parts put together making a very descent DDS VFO capable of any frequency between 1Mhz and 30Mhz. Remember, your operating frequency will be the VFO frequency or an integer multiple thereof , so the VFO may not show your actual operating frequency. The VFO uses an AD9850 DDS chip to synthesis a nice 1Vp-p sinusoidal wave. Programov za tak VFO je na spletu ogromno, zato jih tukaj nimam namena opisovati. This count is used to recalculate the 25 MHz. Remember: This is a DDS. The kit supports the full output range of the Si5351A, which is 3. DDS VFO Assembly Manual. AD9850 ARDUINO PDF - Im newbie. New listing AD9850 DDS Signal Generator 0-55MHz Test Equipment VFO SSB Accessories DIY Parts. Дело в том,что мой дисплей не работает с другими библиотеками кроме Adafruit_ILI9341 пробовал разные TFT TFT2 UTFT UTFT-master с разными вариантами подключений,есть много. DDS VFO demo Using AD9850 and Atmega328P Amogh Desai 25/12/2014 3 I put together this breadboard version of an AD7C designed DDS VFO demo with a little help from pen friend AB9XC Pravin Kumar Anandan. I still lack some basic test equipment (frequency counter, RF probes, etc. ad7c_dds_vfo_schematic. This little VFO just looked too small to be stable. VFO na Si5351A; GPSDO – GPS Disciplined Oscillator; Analizator antenowy EU1KY; Genarator DDS na AD9833; DDS AD9850 i Arduino – wyśw. I modified this code from ak2b to use the ad9850 instead of the si5351. To je ultra prost IDE koji je nastao iz Arduino serije programskih okruzenja. The Arduino Nano is available on Ebay for around $4. Този проект използва PIC16F628A и AD9850 или AD9851. Arduino Forum > Using Arduino > Programming Questions > ad9850 // int to hold the arduino miilis since startup. El ad9850 realmente es un convertidor digital a analogico y el vfo debe ser un oscilador sinuidal de verdad. VFO with AD9850 Because I had no spare LCD display available, I amended the Arduino sketch of Richard, AD7C in order to use an 8 digit seven segment LED display. Using digital pins 8 through 11, proto shield installed. Responder Eliminar.
