Subject: AVR code part 01

AVR code I/O part 01:
This code use AVRStudio and WinAVR (third party), ATmega8535.

Originally posted by kyrios #include <avr/io.h> //standard library #include <stdint.h> //  old version use #include <inttypes.h> #ifndef F_CPU #define F_CPU 4000000UL // define frequency #endif #include <util/delay.h> int main(void){   DDRA = 0x00; /*   set portA as input   */   PORTA = 0xFF;  /*  pull-up active   */   DDRC = 0xff; /*   set portC as output   */   PORTC = 0x00; /*   no pull-up active   */   while(1){     /*   Testing I/O   */     PORTC = 0x00; //  you can use it as 1 byte     loop_until_bit_is_set(PINA,PA1);     PORTC = 0xff;     loop_until_bit_is_set(PINA,PA1);     PORTC &= ~(1<<PC0); //  you can use it as a bit     loop_until_bit_is_set(PINA,PA1);     PORTC |= (1<<PC0);     loop_until_bit_is_set(PINA,PA1);   } }

explanation :
at AVR we can set the direction port using DDRx i.e. DDRA for PORTA, DDRB for PORTB, DDRC for PORTC and DDRD for PORTD.
If bit DDRx is set, it is define that you are using PORTx as output, and if bit DDRx is clear, it is define that you are using PORTx as input.

In AVR, to check the input pin, it is use PINx in the code. to give an output ,it is use PORTx in the code.
In WinAVR, you can't set or clear a PORT directly as a bit, you must use "bit manipulation".

In the code above,
PORTC |= (1<<PC0) and PORTC &= (1<<PC0), it's mean that PORTC at bit 0 is set and PORTC at bit 0 is clear.

so can I use bit manipulation for checking input?
of course you can.
In the code above:
loop_until_bit_is_set(PINA,PA1);, it's mean that the code will keep looping at the same line until PINA at bit 1 is set. This code as the same as:
while(!(PINA&(1<<PA1)).

loop_until_bit_is_clear(%WaitingPIN%, %WaitingBit%), it's mean that the code will kepp looping at the same line until %WaitingPIN% at bit %WaitingBit% is clear. This code as the same as :
While(%WaitingPIN%&(1<<%WaitingBit%)).
