Project Information; In the project, digital filtering is required for precise weighing of a weighing system electronics. The thing to be considered here is that the filtering should have a maximum delay of 500ms and should be adaptively effective filtering against mechanical and electrical noises. Here's the problem I'm having. In the filtering I developed, there are 2000 grams on the scale. And I give mechanical vibration. 2006-1994 grams fluctuate between grams. When I increase the filter value, I reduce it to 2002-1998, but this time both the filter response is very heavy and I cannot detect sensitive grams such as 1-2 grams. What needs to be done is a fast filtering that will work in every system and I want to design a filter that provides a change between 1999-2001 when mechanical vibration comes. The filter must be adaptive. Because the vibration does not have a specific character. The frequency and character of vibration is variable. Project Requirements. ->Know Embedded Systems; ->Developed applications related to digital signal processing. ->Used STM32 ->Digital Filter has developed and worked on this. -> C programming language

I've seen this project many times and seems like you are not able to find right person for the job. I need to evaluate the hardware design first to see if the board was designed properly. May be it's not just the filtering part only ? Please connect to discuss further only in case project fee doesn't bother you. Thanks

Hi! I can help you with a precise weighing system electronics project. Being an adept developer in digital signal processing with hands-on experience in STM32 and adaptive filtering, I’m ready to deliver a fast and effective solution that meets your unique requirements. I make sure to comply with ISO, IEEE, and IEC Standards in delivering your algorithm. I have questions to ask: • Could you provide more details about the specific requirements for adaptive filtering in terms of frequency response characteristics? • Can you clarify the desired trade-off between sensitivity and stability in the weighing system? • Is there any existing digital filtering algorithm that you have already implemented in the project? Project Deliverables: • Digital filtering algorithm design & methodology. • Source code • Test results and performance • Design & Documentation on the integration of the filtering algorithm Qualified Experience: • Over 6 years of experience in developing digital filtering algorithms for precision weighing systems, in embedded systems development, specifically with STM32 microcontrollers, in digital signal processing and adaptive filtering techniques, and a strong background in C programming language for embedded applications. My software proficiency: • MATLAB or Mathematica • STM32CubeIDE Looking forward for your positive response! Best Regards, Abubakar

Good morning, I am a highly skilled and experienced EE engineer. You want a filter design that focuses on optimizing noise rejection and response time. I think the correct answer is Kalman Filtering (KF). Beyond EE engineering, I also master aerospace engineering and I am familiar with KF techniques and implementation. Please DM me to discuss further. Greetings, Jean Paul PS: I happen to be also very proficient in C/C++ programming and have a large experience of STM32 MCUs (there are plenty of nucleo boards in my lab)

Having worked extensively with STM32 and completed several projects involving digital signal processing and firmware development, I am confident in my ability to deliver a precision software filter solution for your weighing system. I understand the specific challenges you face with mechanical and electrical noise interference impacting the accuracy of your readings. With my expertise, I will be able to maximize the impact of your filter without sacrificing sensitivity. I have successfully tackled similar problems before by employing adaptive filtering techniques suited to tackling a wide range of mechanical vibrations. My experience has equipped me with the knowledge of how to effectively manage variable frequencies and different characters of vibrations in system designs. On top of that, my familiarity with C programming language makes me well-equipped to handle the software needs of this project. I understand just how crucial it is to maintain a maximum delay time of 500ms and ensure a change between 1999-2001 grams when vibration occurs. In choosing me for this job, you'll be enlisting the services of a skilled professional who values both accuracy and efficiency in their work.

Hi, I have already developed filters of this type on STM32. To be honest, it is not certain that you can reach the required sensitivity in the times indicated, it depends a lot on the type of hardware filter present on the electronic board. If I can help you, it would be a pleasure
