Petit travail sous Eagle Free, schéma et implantation. La variation de fréquence se fait par . A little quick work with a protoboard and I have a nice working VFO. This page will follow that design and address the Arduino in general.
FOTO: MONTAGEM COM O ARDUINO NANO Resolvemos publicar este DDS usando o Arduino com controle remoto, como estou descrevendo como iniciar no Arduino via radio, ou seja montando coisas par uso em radio, no blogspot arduino4radio. Give new life to an old Codan that is .
The Arduino Uno DDS VFO HF signal generator project is designed as a test equipment project for home construction of test equipment used for ham radio. Designed with a frequency setting range of 20KHz to hopefully 75MHz, but spectral performance may be poor. Audio tones from 1Hz to 20KHz have been provided. Wonderful simple project from AD7C.
An Arduino based VFO using a cheap DDS module from ebay. Frédéric DI MANNO, F1HKJ. I built a simple VFO for a direct conversion receiver I am putting together.
The other reason why I have built the VFO as a standalone device and not using an Arduino is the point above.
My Arduino is only a 5V version. Probing the DDS chip with a scope showed that it . Le signal est carré ou sinusoïdal selon la sortie . Construire un VFO DDS piloté par Arduino. Build a 1-60MHz DDS VFO prototype, breadboard and write. Sketches, with Buffer amps to be designe and PCB Using your own laptop.
Go on to build other useful stuff – RF Meter, Digital mode transmitters, QRP Transceiver, SWR Meter…. Or start at the beginning. Super- Vfo is really a DDS VFO software program for Arduino Uno and Arduino Pro.
VFO without requiring any button more. Mini 16Mhz, with TFT screen 2. Here is the layout: I use clkfor the vfo and clkfor the bfo. Your LCD may have a current limiting resistor already installed . As well as use of the DDS Shiel the new VFO exploits an I2C interface for the LCD display unit to save on the load on Arduino pins, freeing up some pins to use to support input push-buttons. I obtain the code for your Arduino vfo thanks ron hathcock.
