FAQ
What platforms do you support?
I specialize in STM32 family (F0, F1, F4, F7, H7), Nordic nRF52/nRF91 series, ESP32/ESP8266, Raspberry Pi, RISC-V processors, and other ARM Cortex-M based microcontrollers. If you have a different platform, feel free to ask!
What programming languages do you use?
I primarily use C/C++ for firmware development, which is the industry standard for embedded systems. I also use Python for testing frameworks and automation scripts when needed.
Do you provide source code?
Yes! All packages include well-commented source code. You'll receive complete project files that you can compile, modify, and use in your products without any restrictions.
Can you work with existing code?
Absolutely! I can debug, optimize, add features to, or refactor existing firmware. Just provide me with your current codebase and requirements.
What if I don't have hardware yet?
No problem! I can recommend suitable hardware based on your requirements, or work with simulation/emulation tools. I can also help with hardware selection and even provide PCB design services.
Do you provide debugging support?
Yes, debugging is included in all packages. I use professional tools like J-Link, ST-Link, and various oscilloscopes/logic analyzers to ensure your firmware works reliably.
How long does development typically take?
Timeline depends on complexity: - Basic projects: 3-7 days - Standard projects: 1-2 weeks - Premium projects: 2-4 weeks Rush delivery available for urgent projects (+50% fee).
Do you provide documentation?
Yes! All deliverables include: - Code documentation and comments - User guide/API documentation - Hardware setup instructions - Testing procedures
What about intellectual property?
You own all the code I develop for you. I can sign NDAs if required. Your project details remain completely confidential.
Can you integrate with cloud services?
Yes! I have experience with AWS IoT, Azure IoT, Google Cloud IoT, and custom REST APIs. Cloud integration is available in Standard and Premium packages.
