SPI (serial peripheral interface) using AVR microcontroller (ATmega16) Missing Code2

[Dimitrios Mitsas]

Greetings all.

 

I found this brilliand example that you have about spi comunication between two avrs. The only problem is that when i am not logged in i can see code and code2 tabs. But when i login i can only see code tab and not the code2. Where can i find that code?

Thanks.

The code available seems to be of the receiver (slave) microcontroller and as you said the transmitter code is missing. But they have given the steps of the programme for the transmitter also. Here it is

 

1. Set SS, MOSI and SCK pin as output pins.

2. Enable MSTR bit to make it master device.

3. Program SPR [1:0] bits to select SCK frequency.

4. Set SPE bit to enable SPI.

5. Copy data in SPDR register to send.

6. Wait until SPI interrupt flag get set.
