I URGENTLY need someone who can quickly respond and work in 1-2 days to make my DDS work. I'm giving you all the information you need in this description. Additionally, you can send me a message if you have any doubts. And please bid on it as soon as possible, since I will make a decision within hours. And I want the code in 1-2 days max. (And yes, it is possible to do in 2 days)
*****PLEASE DON'T BID IF YOU ARE NOT CONFIDENT****
***** A FREELANCER HAS ALREADY WASTED MY 15 DAYS AND GIVEN ME NOTHING*****
***** PLEASE, I CAN'T AFFORD TO MAKE THE SAME MISTAKE AGAIN****
>> Software: KeiluV (mandatory), STM32CubeMX (optional)
>> Hardware used: STM32F4-Discovery, connected to DDS AD9832 (Connections can be found in uploaded files)
>> Important information related to the device and its programming : Can be found in uploaded files
****** IMPORTANT INFORMATION ******
1) For anyone who wants to know the basics of DDS, please refer : [login to view URL]
2) Requirement: 500mV sinusoidal wave: As far as I have understood from the datasheet, the amplitude is not programmable, so it is set using a resistor (RSET : please see datasheet pin description for details). So I am using a 9.1kOhm resistor to set the output to 500mV.
****** YOUR JOB IS TO GENERATE A SINEWAVE *********
3) There are two ways of programming the DDS : Using SPI and GPIO (Both of these connections are possible). If you see the connection diagram, we will just remove the resistors R47, R48 and R49 if you are using the SPI. Or opposite if you plan on using GPIO. Please also find the microcontroller pins in the diagram.
******* I WILL PREFER SPI, BUT YOU CAN DO GPIO IF ITS BETTER FOR YOU*****
You can either use STM32CUBEMX to do all settings and generate code for MDK-ARM V5 and then add the necessary extra code or you can use a library or you can do it on your own. Its completely up to you.
*********** THE CODE HAS TO WORK ON KEIL uV 5**********
********** THE CODE SEQUENCE AND ITS MEANING CAN BE FOUND IN ATTACHED PROGRAMMING EXAMPLES ************
********** FOLLOW THAT TO SEND DATA TO THE DDS **********
********** ITS AS SIMPLE AS THAT IF YOU ARE EXPERIENCED WITH STM32*********
********** I USE WINDOWS 10 AND NOT LINUX ***********
FEEL FREE TO MESSAGE ME FOR ANY FURTHER QUERIES. AND MAKE YOU BID WITH THE BUDGET AND SELECT A CODE DELIVERY DATE FOR <2 DAYS TO GET A REPLY.
Hello sir,
I have experience in designing electronics circuits and can develop hardware compatible smartphone and PC based apps.
I also have done a lot of IoT projects and can transform your idea into a fully working product.
If you wish we can discuss details in chat.
And i can show you another project which i recently done on AD9837 chip with STM32F microcontroller and Keil 5.
Thanks
For more details inbox me so that we can discuss in detail. For more details inbox me so that we can discuss in detail. For more details inbox me so that we can discuss in detail.
I DO NOT OUTSOURCE I have been a freelancer for the past 8 years, I believe that my experience and skill in this background will prove to be of great help to you. Contact me to discuss more on the details
