A single prime number benchmark sketch.
forked from : https://github.com/RalphBacon/LGT8F328P-Arduino-Clone-Chip-ATMega328P
Modifications :
- runs out of the box on LGT8Fx boards @ 16MHz using default Arduino Nano core.
- runs out of the box on LGT8Fx boards @ 32MHz and 16MHz using Larduino_HSP core.
- runs out of the box on old Arduino boards that does not have GUID
- runs out of the box on non AVR boards
Calculate 10,000 prime numbers :
-
