Ad9833dela
To program the pic32 to generates voltage signals sine waves for AD630 and calculating sine waves(frequency ,reactance, resistance, amplitude ,phase) using SPI interface for AD9833 Dds function generator And also to display the oled screen with code using pic32 micro controller with SPI interface . I need a code .
Hello, I have a frequency generator made with a arduino UNO + AD9833 + TIP31+ step up converter (DC) I can set the frequency via the serial monitor in the arduino software Then the circuit can be unplugged from the computer and powered by a 12V power source and will work independantly The circuit produces an electric signal with a min voltage of 0V, max voltage between 12V to 48V (with 1V precision) (set with a step up converter), frequency between 1hz to 100000hz (with 1hz precision) (set with serial monitor), square waveform, 50% duty cycle, the device works well but there was a problem (bug / error) that the designer of the circuit did not manage to fix : sometimes the frequency which is uploaded to the device results in an appropriate signal, but sometimes, for some reason, t...
Project for a turntable motor driver needs SW modification to control an AD9833 DDS. The uC will switch between two speeds (33 1/3 and 45 RMP) in a 30 sec interval. The output frequency will be derived from a 4 MHz crystal.
I have the AD9833 wavefom generator module like in the below: The datasheet for the AD9833: I need to use STM32F4 Discovery board and control the AD9833 chip via SPI. The user should be available to select sine, square or triangular
Features of DDS Function Generator 1. Compact uC based system with 2 Line LCD interface & keypad (4 keys) and two potentiometers. 2. Settable frequency from 0-1MHz with a resolution of 1Hz in all ranges. 3. Potentiometer-1 used for Coarse Tuning & Potentiometer-2 used for Fine Tuning of the frequency setting. 4. Four Keys – UP Key, DOWN key for Range Selection, Waveform Select key & Enter key. 5. The following table consist the range selection, with accuracy & resolution: Range Selection Potentiometer-1 Range – Coarse Tuning Potentiometer-2 Range – Fine Tuning Accuracy Display Resolution 1. 0-10Hz 0-10Hz - +/- 1Hz +/- 1Hz 2. 10-100Hz 10-100Hz - +/- 1Hz +/- 1Hz 3. 100-1000Hz 100 – 990Hz 0-10Hz +/- 1Hz +/- 1Hz 4. 1KHz-10KHz 1KHz &nd...
...variable time and waveforms. For example: Channel 1 outputs a 100KHz square waveform for 20 seconds then a 6MHz sine wave for 15 seconds. While channel 2 outputs 300KHz sine wave for 5 seconds then 450KHz sine wave for 5 seconds then 3MHz for 10 seconds then 185KHz square wave for 20 seconds. Each channel will continuously loop. Microprocessor - Atmel AVR (preferred) but will consider others AD9833 Programmable Waveform Generator AD603 Variable Gain Amplifier Specifications: Frequency range: 100Hz – 6MHz (Sine), 100Hz-1KHz (Square) Voltage Input: 9-12VDC Wave Amplitude: 0.5V Vpp~9V Vpp (software adjustable) Bias voltage: -4.5V~4.5V (software adjustable) General Notes: • All code needs to be well annotated. • Price needs to inc...
I need to do a hardware that can read an input from a PC via RS232 to produce a sine wave at a specific frequency. The hardware must use a 16F877 PIC microcontroller and AD9833 (signal generator). I need someone to provide me with the programs, both in high level language (preferably Matlab) for sending out input; and the assembler program for the PIC. The programs must be fully commented. I also need a simple sketch of the circuit diagram. For your bid to be selected, send me an assembler program that can produce a 5MHz output using just the PIC and the chip, i.e. turn on the PIC and produce a 5MHz sine wave. I'm not expecting to pay more than $100 for this job. The full payment will only be made once all programs have been sent and tested. Thanks for reading a...
