Hi all
I am trying to communicate using SPI protocol between two arduino uno boards. I have writthen a very simple code to transfer a single character from master. The code is as following#include <SPI.h>
#include "pins_arduino.h"void setup (void)
{
}void loop (void)
{digitalWrite(SS, HIGH); // ensure SS stays high
SPI.begin ();
delay (5000); // 5 seconds delay to start logic analyser.
// enable Slave Select
digitalWrite(SS, LOW); // SS is pin 10// send test string
SPI.transfer ( 'c');// disable Slave Select
digitalWrite(SS, HIGH);// turn SPI hardware off
SPI.end ();while (1); //loop
}Please correct the code if its not right. And I really want to know that how to recieve that character on arduino uno in slave mode. There is a command SPI.transfer() to send data on SPI where as I haven't seen any command to recieve it.
Thanks and regards
Hi, wrong topic...

Hi,anyone who can tell me if i should use the 60° or 40° FOV??
And should i need a Lens?Thanks a lot.
Cu kami
it depends on your intended application, and which one you can find (I was looking for the 40° version but futureelectronics had only the 60° one, so I bought that...)
