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). 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 PORTB |= 0x01 //1 word, 2 clocks on ATmega2560. 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).

Just search for Arduino CH340 driver and you will find a number of sources for drivers depending on what Windows or Mac operating system you are using.

If you have any issues with connecting to the board, you may need to download a driver. The board uses the CH340 chip for USB communications. These are nice compatible assemblies with very good build quality. Refer the the Arduino documentation for all possible functions for the pins. The attached Mega 2560 board pin-out shows the most commonly used functions for the pins, but some pins can support other functions. Our 7.5V AC adapter works extremely well for powering these boards. Higher input voltages will cause the on-board regulator to work harder and may cause it to overheat. If an external supply is used, it is recommended to use a supply between 7-12V. The power source is selected automatically if both are available. The Mega 2560 operates at 5V which can be supplied via an external power supply or through the USB port connection.

16 Analog inputs that can also be used as digital I/O for a total of up to 70 digital I/O.
