@zilators (il te faudra un programmateur d'avr ICSP pour changer les "fuses")

Fuse-wise, you need to make sure the primary one has Full-Swing Crystal Oscillator enabled[1] (not the Low-Power one you typically find enabled by default when you burn an arduino bootloader via the IDE), the ClockOut fuse bit is enabled, then PORTB0 (aka digital pin 8 on an arduino) has to go into XTAL1 on the 2nd one and that one needs its fuses set to External Oscillator. Likewise, digital pin 8 on the first processor can't be used for I/O. For the 328P, example fuse settings... Master (with the crystal across XTAL1/XTAL2 and 22pF ceramic caps between each XTAL line and GND)- Extended fuse: 0x05 (BOD enabled) High fuse: 0xDE (Self-Programming enabled, Reset Vector=Bootloader) Low fuse: 0x97 (CLKO, SUT=01, CKSEL=Full Swing Oscillator) **note that the exact fuses may differ depending on what kind of crystal/resonator you have: A quartz crystal with BOD enabled, as we have...
