I did not show the accelerations on my serial screen whenever I move the accelerometer. So, I purchased an accelerometer MPU 6050 (GY 521) and Arduino Mega 2560. The Arduino Uno pinout consists of 14 digital pins, 6 analog inputs, a power jack, USB connection and ICSP header. The ATmega2560 however a problem - they ran out of registers in the low I/O space (the bit set clear test instructions only work on the first 32 addresses).I am doing a project in which it requires the accelerations of hand. If(VPORTB.OUT & 0x01) // 1 word 1 clock for the test, and 1 word for an rjmp (2 if it for some reason needs a jump, but the linker rarely does), just like beforeĤ. VPORTB.OUT |= 3 //3 word, 3 clocks, and not atomic. VPORTB.OUT = 1 // 2 word 2 clock *and not atomic* VPORTB.OUT |= 1 // 1 word and 1 clock (sbi/cbi got faster!) Those are in the low I/O space, and can be accessed like the old PORTx/DDRx/INx registers: The modern AVRs also have "VPORTx.DIR/OUT/IN/INTFLAGS registers. Luckily, DIR and OUT have set/clear/toggle versions - these still take 3 words and 3 clocks to do say, PORTB.OUTCLR = 3 (which would clear the two low bits) but at least it's atomic. These are in extended I/O space, so writes will generally take 2 clocks and reads three, plus the time to prepare the value you want to write (so PORTB.OUT |= 1 would be 5 words and 6 clocks, and is not atomic). arduino mega pinout v2 : Pinout search. On post 2016 AVRs, the register layout is different, PORTB/DDRB/PINB is replaced with PORTB.OUT, PORTB.DIR, PORTB.IN.PORTB |= 0x03 // 3 word, 3 clocks, and not atomic. PORTB = 0x01 // 2 word 2 clocks, *and not atomic* If (PORTB & 0x03) // 2 word 2 clocks for the test then 1 word for a breq/brne - and potentially an extra 1 and 2 ontop of that for an rjmp since conditional branches can only go 64 words in either direction. If(PORTB & 0x01) // 1 word 1 clock for the test, and 1 word for an rjmp (2 if it for some reason needs a jump, but the linker rarely does) - the test instructions are sbic/sbis (Skip if Bit in Io register Clear/Set), that is, they test the bit (taking 1 clock to do so, and depending on the value of the bit either skip (takes 1 clock) or don't skip (takes however long it normally takes) the next instruction, which is almost always a jump of some sort rjmp takes 2 clocks, jmp 3 clocks) Either way, this is atomic, and you don't have to worry about an interrupt firing in the middle The Arduino MEGA 2560 is designed for projects that require more I/O lines, more sketch memory and more RAM.

PORTB |= 0x01 //1 word, 2 clocks on ATmega2560. Find out topics and tips or connect with users from the Arduino Forum. PORTx (and DDRx (Data Direction Register) and PIN (PortINput) are "magic" registers because they are located in the "low I/O space", which makes it possible to set, clear, or test them with a single instruction work that executes in 2 clocks on a pre-2016 AVR.Since according to notifications people are still reading this, there are a few things also worth noting: Note that you can also toggle the pin in a single operation by writing a 1 to the PINx register, ex: They typically show the port pin as P, followed by the letter of the port, then the bit within the port (for example PB0 for the pin you referred to). See a pinout chart (google image search will find nice pinout diagrams - just search the board and the word pinout).
