primes

Counts prime numbers in a microcontroller.

V1.0

• Uses 8 LEDs to display the number.
• Counter goes from 0 to 255. After that the counter resets.

V2:

• LEDs were changed for a 4-digit 7-segment display.
• Numbers go from 0 to 7000 (Max). After that the counter resets.
• the last number displayed is stored in EEPROM.
• The numbers from the EEPROM are retrieved when the uC is powered on.

Hardware connections (using the hapkit board) for V2

• A 4-digit 7-segment display (D2-D13)
• A push button connected to port A0.
• A buzzer connected to port A1.
