hi guys… im a new user of arduino… i just want to ask if i can initialize a port?
int portLED = PORTD;
void setup ()
im trying to compile the code above but i shows some error message :’(… i hope you can help me guys… thank you so much…
There is no arduino command in the form you tried that will write all bits to a port at once. If you need to do this you can use the low level functions for direct port IO. The reference page on port manipulation is a good place to start: http://www.arduino.cc/en/Reference/PortManipulation
ok sir… i’l try it… thank you so much! ;D
Oh, I forgot to mention that there is a link to a good tutorial on bitwise math on that page, its well worth reading this if you need help on working with code that operates on some but not all bits.
