Hi,
Have a Great Day. Iam Electronics Engineer having more than 10 years of R&D experience. I worked with high speed image captuering hardware like Atmel AVR and camera+ SD card, Unipolar and bipolar stepper motors driver circuitary with variable RPMs, Servo Motors etc.
I will suggest to use Proteus so that a complete Project can be built from Simulation to PCB design.
Please feel free to contact.
Best Regards,
Shahbaz.
