OPENRPNCALC CUSTOM SCIENTIFIC RPN CALCULATOR BASED ON STM32 1

OPENRPNCALC: CUSTOM SCIENTIFIC RPN CALCULATOR BASED ON STM32

Reverse Polish Notation (RPN) is a popular method for representing mathematical expressions. In this notation, the operator symbol comes after the operands in contrast to the Polish notation, where the operators are placed preceding the operands. For example, the Polish notation for the addition of 2 and 5 is 2+5, while in reverse Polish notation, it

VFD Display for the TI83 Calculator

VFD Display for the TI83+ Calculator

This project builds upon the PIC/TI83+ interface developed by ThomasHenry (see Nuts & Volts August 2013 – A Mathematics Engine for Microcontrollers). Acknowledgment, appreciation, and kudos to him for writing the TI-library for Great Cow Basic that made this project possible. When I recently re-discovered that article, I imagined re-creating the only calculator that was

CHIP HALL OF FAME INTEL 4004 MICROPROCESSOR

CHIP HALL OF FAME: INTEL 4004 MICROPROCESSOR

The Intel 4004 was the world’s first microprocessor—a complete general-purpose CPU on a single chip. Released in March 1971, and using cutting-edge silicon-gate technology, the 4004 marked the beginning of Intel’s rise to global dominance in the processor industry. So you might imagine that the full resources of Intel—still a fledgling company at the time—were devoted

Prime Calculator is Complete using ATMega8 Microcontroller

My microcontroller-powered prime number generator/calculator is virtually complete! Although I’m planning on improving the software (better menus, the addition of sound, and implementation of a more efficient algorithm) and hardware (a better enclosure would be nice, battery/DC wall power, and a few LEDs on the bottom row are incorrectly wired), this device is currently functional
