New product (hardware+firmware) based on an existing product

Deliverable: functional prototype with design files (Kicad schematics, Kicad PCB file, Gerber files, BOM, source code, binary) Scope: inclusion of current sensor to a load control device Description: We have an old product that uses a relay to connect/disconnect an external load. It receives commands from a bus using a proprietary protocol. We need to add a current sensor to this product. Architecture: the existing product is based on a PIC12F1840 programmed with Assembly language. We would like to update the microcontroller to STM32F070F6 and the programming language to ANSI C. So the job consists of replacing the MCU and adapting the code to the new platform while adding the ACS712 current sensor and the code needed for it to deliver an accurate measurement. We already have an enclosure for the product, so board dimensions should not change: 40x50x25 mm. The code for the proprietary protocol will be supplied in ANSI C.

I can do this nicely for you. Have been working dedicatedly on STM32Fxxx series since last 4 years beside having programming skills in C for over 25 years. Very good understanding of both Analog and Digital designs. Let's have a discussion so that I can share more details about my skills and plan. I have been working on industrial designs from concept to final product realization. Thanks for your time and I look forward to hearing from you. Best Regards ... Roy

Hi Lets get directly into details I have worries about board size if the current you sense is too high you will need large pads or connectors which will consume large area or your already small PCB. Everything else is ok for me for now. About me I’m an embedded hardware engineer with over 18 years in Micro-controllers firmware development and PCB design. Proficient at all stages of design from prototyping till DFM / DFA / DFT production cycle. I can easily reverse the pic12F1840 code and rewrite it for STM32f070 along with analog ADC interface for ACS712 I invite you to chat to discuss further details.
