1/15/2024 0 Comments Arduino uno led datasheetSection “I/O-Ports”, subsection “Register Description”. The address of PORTB can be found in the ATmega328P datasheet, The above code is simply for blinking LED light Does arduino has it that gives memory mapped addresses? there should be a some datasheet for this what its called. What is the values correspond to DDRB and _BV(DDB5) and PORTB and _BV(PORTB5) ? I like to do it with pointers so I need addresses of PORT B all pins I know the macros but I like the actual addresses. Now assume I have a code that uses avr gcc #include //avr/io.h ![]() What if I dont want to use any library and just write to address and I need PORT B pin address how to refer to different pins? Then should I expect that I am writing to some pin so I like to know which data sheet I should refer for pin addresses of port B?Ĭurrently my code is not working because no matter which pin I connect my LED to it blinks. How Port B pins are addressed with corresponding pin numbers like What is the address of digital pin 13?Ĭurrently I am assuming its pin address is 0x05 so my pointer looks like this uint8_t *adr=0x00+0x05 Is there an memory address associated with this pin 13 of Arduino Uno r3? ![]() So Let say I want to access Digital Pin 13.
