We are looking for an embedded firmware engineer with experience with the ARM Cortex M processors to write DSP filters in C code using Matlab as the input for the filter design and coefficients. We are using the STM32F4 family of processors and one of the filters that we want is a 42 tap bandpass filter with a center frequency of 200 Hz. We can provide the filter design along with the header file from Matlab and we would want working C code. We are using the Keil MDK Version 5 and it would be best if you use the same. We have a few other filters that we will want coded, and there will be several reiterations of the 200 Hz notch filter, so this should result in some ongoing work. We also could always use the skills of someone experienced with the ARM Cortex M processor.

Hello I can design you the filter for ARM (STM32F). The filter can use fixed of floating arithmetic. There are several libraries available as well. These libraries are optimized for ARM architecture. I can use GCC or Keil. Regards Ondrej

Hello! I am an electrical and electronics design engineer. I have three years of experience in design of electronic products, PCB layout and analog/RF designer. I am experienced in the following fields: 1) Embedded systems: Years of experience with most popular architectures and MCUs, always up to date with every new innovation. Worked on Microchip PIC and ARM Cortex-M4 (C language). I have good experience with RTOS as well like FREERTOS and TI RTOS. Worked using Keil, TI CCS, Eclipse. 2) PCB Design and manufacturing: 2 years experience in using Altium software for designing PCBs including RF circuits. 3) Analog desinger. I have 2 years experience in and Analog Video Transmission. 4) RF designer: I also have experience in RF Power Amplifier, Low Noise Amplifier( at and ), designing Vivaldi antenna/RFID antenna, RF filter and Impedance matching. 5)Good use of the ADS and CST simulation software for analyzing Microwave RF circuits and Matlab software. I did work on band pass filter with different central frequency, High pass , etc I would love to work on your project, Lets discus it further via chat Thanks Kind regards Robin

Hello, I have over 3 years of professional experience related to embedded software development for STM32F4 microcontrollers. My past projects include an IMU and autopilot modules for a small UAV, a PMSM sensorless FOC motor controller, and various communication modules. I have worked on STM32F407, STM32F439 and STM32F446. Could you provide me with more information about the requirements of the project? Is it simply an implementation of a FIR filter, or is there more to it (e.g. some sort of interface, parameters storage mechanism etc.)? I am looking forward to hearing more from you. Best regards, Piotr Juda
