I2C Man-in-the-Middle
Sorry for not reading too much of the thread the first time, but your last post #9 paints clear picture. (Even though I'm not 100% sure it's the right picture). And you...

I2C Man-in-the-Middle
First tool you need is of course a Logic Analyser. Follow my signature for a EUR 7 version.   2nd tool you need are devices that are capable of "Multi Master Mode". ...

Help me to understand subroutines(RET)
If you really want to learn asm, then I very stronly suggest to get decent development tools for it. Learning ASM without a debug environment in which you can single step through...

Crimper search - Classified Unobtanium
Pliers like those are not much more than a few pieces of stamped sheet metal and some sintered metal parts. Such a plier costs a few EUR to make, but in this world there simply is...

tinyAVR DAC Tone Generator on Slow Clock Speed
 Triangles are very easy to do in software. Just take a variable, and add a constant to it, and then output the variable to the DAC. At some time (depending on the constant)...

tinyAVR DAC Tone Generator on Slow Clock Speed
What would ever be a good use of using an 8kHz clock speed for an AVR? Just run the thing at a few MHz and put it to sleep when it has nothing to do.

Different working speeds at the same baud rate
USB data is packetized, and generally an USB node is serviced only once every ms. That may mean that if your RS232 device sends a byte and then waits for a response such a...

Different working speeds at the same baud rate
May I yet again recommend a simple logic analyser? (See my signature).   It shows if your baudrate is 0.1% off. It shows the distance between bytes. It changes guesswork into...
