Dear Sir or Madam,
This is to advise You about a free offer of the goods to the following effect:

• 32-bit Arithmetic Routines with Macrolibrary for the AVR family of microcontrollers

  This package of assembler subprograms is developed for integer arithmetic with tracing of sign bit in 32 bits calculations and data reloads. It is based on microcontroller register file to the maximum. In real users projects available abundant digit capacity allows to avoid overflow and reduces inaccuracy of rounding errors in chain calculations. Included macro definitions will increase readability of assembler source at bit by bit and multibyte data operations inside software model of Atmel AVR devices

• Multibyte Arithmetic Routines for the AVR family of microcontrollers

  This is the fixed point package, which provides many digits of accuracy in assembler computations with an operandes in the memory. It is based on the features of AVR software model and optimized for code size

• Two-wire synchronous serial interface inclusion

  It is my compact transformation of AVR300: Software TWI Master Interface, which was corrected and tested for Sequential Read also

Yours faithfully,
Andre Birua, programmer
