Compiling Jeelib for Attiny84 with 16Mhz external clock
When trying to compile for a clock higher than 10Mhz, the lines below from RFM12.cpp is causing “error: ‘SPCR’ was not declared in this scope”.
AFAIK the Tiny84 doesn’t have SPI and the code below is for Arduino etc.
So is it okay to comment it out or do I need to find and include #defind for tiny from somewhere?
// slow down to under 2.5 MHz #if F_CPU > 10000000 bitSet(SPCR, SPR0); #endif
I have the same error message:
/Users/bine/src/Arduino/libraries/jeelib/RF12.cpp: In function 'uint16_t rf12_xferSlow(uint16_t)': /Users/bine/src/Arduino/libraries/jeelib/RF12.cpp:247:12: error: 'SPCR' was not declared in this scope bitSet(SPCR, SPR0); ^ /Users/bine/src/Arduino/hardware/tiny/avr/cores/tiny/wiring.h:152:30: note: in definition of macro 'bitSet' #define bitSet(value, bit) ((value) |= (1UL << (bit))) ^~~~~ /Users/bine/src/Arduino/libraries/jeelib/RF12.cpp:247:18: error: 'SPR0' was not declared in this scope bitSet(SPCR, SPR0); ^ /Users/bine/src/Arduino/hardware/tiny/avr/cores/tiny/wiring.h:152:49: note: in definition of macro 'bitSet' #define bitSet(value, bit) ((value) |= (1UL << (bit))) ^~~
Is there a solution available?
Could you give this branch a spin?
Thank you! With this tree I can compile the sketch!
Great, I haven't tested with ATMega328, if you have time to do this I would welcome your result.
I will ask that this be integrated into the master branch if it works for the 328.
I have no ATMega328 at the moment, therefor I can not test it. Maybe someone else could do this.
BTW I found this https://github.com/SpenceKonde/ATTinyCore useful as Board definitions for the ATTiny's.
I also use the core you found when I do any T84 stuff. I usually use the 328 unit because of the bigger memories. What is your project, are you using Jeelabs hardware or
I will build some Temperature sensors from this site: https://nathan.chantrell.net/tinytx-wireless-sensor/
For this the T84 has enough memory. I ordered yesterday the T84 and the boards, at the moment I can only compile the sketch but not upload it ;-)
