This is a sketch to control an AD9850 oem board with an Arduino Nano or Uno. It uses an OLED 128x64 monochrome display and has very simple functions such as Frequency Change, Frequency Step Control and predefined Frequency Limits.

Jun 3, 2017 · Arduino with OLED – simulated DDS. The U8X8 driver produces those double-size bitmap characters; the default 8×8 matrix seem pretty much unreadable on a 0.96 inch OLED at any practical distance from a benchtop instrument. They might be workable on a 1.3 inch white OLED, minus the attractive yellow highlight for the frequency in the top line.

May 3, 2023 · If you power the Arduino module, The OLED Display will show the increasing Frequency. If you have an Oscilloscope you can connect it to the AD9850 SQ Wave 1 pin (see wiring schematic) or AD9850 Sine Wave 1 pin (see wiring schematic). Congratulations! You have completed your project with Visuino.

AD9850 DDS Signal Generator Module is one of the small, low-cost boards to generate analog signals. This integrated board can be controlled through a microcontroller and can be digitally programmed using Direct Digital Synthesis Technology (DSS).

This is my implementation of a VFO based on an AD9850 which is controlled by an Arduino Nano v3. The VFO is used to pimp my T20P QRP transceiver. The hardware desgin of the VFO is based on Richard/AD7C's AD9850 DDS VFO .

In this tutorial we will learn how to make a Pulse Generator with a Frequency Sweep using DDS Frequency Signal Generator AD9850. Pulse generator will start with 1Hz and increase its frequency for 0.5Hz every second. Once it reaches 10Hz it wil stop increasing the frequency.

22.3.2016 UPDATE – if you are looking to build a radio VFO, there is a newer version of this code available, with more radio-oriented features. I have started to play with amateur radio again and wanted to have a decent VFO/signal generator that could cover most of HF without complicated part switching required.

OLED Display Option for the Bitx40 project! Below is a "paint by the numbers" wiring schedule of how to wire up your Arduino to the OLED, the Si5351 and the Encoder. An alternate is provided for those who want to have the line "Bitx40" change to read "On the Air" during transmit.

Jun 6, 2017 · A white 1.3 inch I²C OLED turns out to be much more readable than the yellow-blue 0.96 inch version: Arduino with OLED – white 1.3 inch. Of course, after you make it readable, you immediately make room to cram more data on it: White 1.3 inch OLED on crystal tester

I build sinus wave signal generator with AD9850 using Arduino UNO, SSD1306 OLED display and AD9850 generator and rotary encoder.
