I'm new to microcontrollers and I am trying to figure out how to send a command from a master uC in order to output a logical '1' at the slave's port pin through ethernet interface.
This kind of MicroController (PIC18F97J60) has an internal ethernet interface and doesn't need an external interface.
I need some guidance as I am new to it.
Is there a simple ethernet tcp/ip code so I can learn from? Or maybe a book that covers that subject?
The following code depicts my general idea , The IF condition should perform only if it gets a data with logical '1' through ethernet TCP IP interface from the master and then it should turn high the RA0 pin.
<pre class="brush: lang">
//The slave MicroController//
#include <xc.h>
#include <stdio.h>
//Initialize variables funcion:
void init (){
TRISA = 0b00000000; //All A pins are outputs
PORTAbits.RA0 =0; //initializing RA0 to 0
}
//main function:
void main (){
init ();
while(1){
if(...){ //If a logcal '1' received from the master through Ethernet TCP/IP then do this:
PORTAbits.RA0 = 1;//Turn the output pin RA0 on
}
else{ //in any other case , turn the output pin RA0 off
PORTAbits.RA0 =0;
}
}
}
</pre>
