    1-wire DS2450 AD converter problem

    Hi, I have some experience with MC34063. However, this step-up converter is too "hangry" for my application. It's power consumption is too high. I would prefer inductorless design. There are few charge pumps from MAXIM (e.g MAX768, MAX1686, etc ) however the ripple volatge is too high. Any...

    need driven motor by 8051

    Sorry, drawwing by chars does not work as I expected. Transistors T1 and T2 have to switched on at the same time for one direction. To change direction in oposit way T3 and T$ have to be switched on at the same time. Do not forget to use PWM if u want to control speed Lm

    How to work with FPGA cores?

    It's very simple. Take the core, instantiate it as many times as you want and download it into FPGA. This way u can create pretty complex systems on FPGA. Would be nice to have A/D on FPGAs, would not be :-). Lm
