ATtiny84+nRF24 worked fine, now errors

Projects Programming
1

Hello,

About 3-4 years ago I was tinkering with some small remote environment sensors. They had been in steady use until about a year ago. Wanting to pick up the project again, jumped right in and became vexed with a slew of new errors when compiling and uploading.

If someone might take the time to review this code and output, perhaps offer some leads for me to resolve this? That be much appreciated.

Thank you, Mark

@bambuino
According to the error output, you are using a standard AVR core.
Isn't it should be a special attiny core for Attiny84? Did you installed it?

Yeah, so pretty much fixed by moving over to ATTinyCore from the ancient attiny (damellis) core, and its need for editing pin mapping and stuffs. My notes were not so great after all, couldn't just pick right up. Built a new programmer, and smooth as butter. With the ATTinyCore I lose about 640 bytes program space, so need to go through and optimize the code on the transmitters, maybe try a new temp sensor without the huge code overhead of a thermistor, like these MCP9700 sensors got from Mouser today.

Reason I got excited the other day was anticipated arrival of an Uno R4, to handle my oversized code for the receiver/data logger. However, there has yet been AVR-style libraries devised to substitute for avr/sleep.h on this Cortex M4. So, when compiling the code for the receiver, a fatal error is thrown from the RF24Network library.

c:\Users\mkapo\Arduino\libraries\RF24Network\RF24Network.cpp:42:14: fatal error: avr/sleep.h: No such file or directory
     #include <avr/sleep.h>

Thinking my next question is something regarding editing the RF24Network.cpp with regard to the Uno R4 so that certain aspects of incompatible AVR stuff is not compiled onto the Uno R4 with the Cortex M-4. I don't need to sleep the receiver base node, but all the other nodes do need be put to sleep, so one library for all would be great.

I am not very good at most of this stuff. But below is what I been working with, photo.
