Hi, I need help to make it work for ATmega328PB in Atmel Studio, pure C code.
I get alots of error and don't really know how to solve them, thanks!

Im using PB1 as Interrupt, PB2 SS, PB3 Mosi, PB4 Miso and PB5 Sck.

if(ACKRequested())
sendACK();

In example gives compilation error.

Error : too few arguments to function 'sendACK'

Hello @nayem-cosmic

I am trying to use your library in the Arduino IDE in the hope to use it with the Attiny84, I did the following:

• Change *.c files to *.cpp
• also renamed to avoid conflicts.
• testing a basic sketch just including the libraries.

when I compile I get this errors when compile for atmega328

sketch\src\RFM69-AVR-C\RFM69avr.cpp.o:(.bss.DATA+0x0): multiple definition of `DATA'
sketch\Test_RFM_AVR-C.ino.cpp.o:(.bss.DATA+0x0): first defined here
collect2.exe: error: ld returned 1 exit status
exit status 1
Error compiling for board ATmega328

I read it can be something related to the millis() function or timer, but I do not really understand that much. I hope you can point in the right direction where to look.

Thank you in advance.

Hi,

I have ported it to Attiny84. Initially the receiver which was using the LowPowerLab library wasn't receiving anything. I've have made some changes to your code to make it work.
Apparently there was an off-by-one error. LowPowerLab has changed the library a bit and I updated your code accordingly (only the sending part).

Attached the unified diff.

Encryption is not working. I checked source from LowPowerLab and found one difference:

RFM69.c, void encrypt(const char* key), line 286-287:

else
  writeReg(REG_PACKETCONFIG2, (readReg(REG_PACKETCONFIG2) & 0xFE) | 0x00); 

must be:

//else - no else, enable or disable on key
  writeReg(REG_PACKETCONFIG2, (readReg(REG_PACKETCONFIG2) & 0xFE) | (key?1:0));

...now it's working fine.
