Using a USB port and compiler It is quite possible to use a mega8 for example to implement a usb slave device which is able to work with low speed usb data rates and can handle one or two endpoints.the main...

Assistance needed If I were you I would have a quick google for multiplexing and the addressing techniques for the i2c bus and i think you will find that your requirement are drastically reduced...

When is it best to use a realtime operating system? Also remember that there are huge differences between REALTIME operating systems and multitasking systems.Most multitasking operating systems are NOT realtime by any definition....

When is it best to use a realtime operating system? The use of an RTOS in an 8 bit application is complete and utter nonsence. it might be used as an easy way to explain the workings of an rtos but the real world applications in an...

Timing solutions This is a good general discussion about Moore and Mealy state machines and how they are used.More from a hardware perspective but still usefull.

Timing solutions I think you need to consider the different state machine models and think in particular about Mealy state machines and how they apply to your problem.In a Mealy state machine the...

Vga -> TTF lcd converter / driver with ATMega Its not really suitable to try to do it with a microprocessor because of the overheads involved.I have however implemented a very similar project using a low end Altera FPGA.Too...

Easy hardware random number generation Well its a pseudo random number generator as any machine generated RNG must be,its a VHDL implementation of the RC4 alogrithm which will fit into any small CPLD.The RC4 algorithm...

rand(); isn't random It doesnt produce truley random numbers because its implmenting a deterministic routine which is producing a sequence of numbers which will always be the same for any given...

Modular Inverse. Not sure if you aware of this method, but ...
I canot do the proper symbols on here but the exponent e can be converted to binary format so that
e= the sum from i=0 to n-1 of A(i...

generating random numbers via eeprom write? The easiest way to generate pseudo random number is using a linear feedback shift register.The lfsr will produce a sequence of numbers which will repeat after 2^n-1 steps if it is...
