Here is the code:
#includeYou need the UART library from Peter Fleury (http://jump.to/fleury).
#define F_CPU 11059200
#define UART_BAUD_RATE 115200
uart_init( UART_BAUD_SELECT(UART_BAUD_RATE,F_CPU) );
uart_puts("Starting low cost logic analyzer.\n");
uart_putc( PINB + '0' );
uart_putc( '\r' );
Unfortunatly i have no software for the data analysis. I saved the data with HTERM as text file so far.
Next project was the modification of my good old LEGO Technic truck.
He needs a huge amount of AA batteries - more than i had. But i wanted to make it work
And it worked. With my old self made power supply it was a joy to play with the truck. ; )
And finally if finished the case for my thermometer. I found some transparent plasic in the cellar. Now only a calibration function for the clock is left.
