Can anyone point me to a simple code example of bitbanding that works on Teensy 3.2?
I tried this:
Am I missing something about what I need to do to get bitbanding to work, or is the address map different than I thought?
I tried this:
Code:
uint8_t st = 0xAA;
dbgprintf("Address of byte on stack: %x\n", &st); // PRINTS 0x20007FD7
uint8_t* bb = &st + 0x2000000;
dbgprintf("Address of byte in bitband region: %x\n", bb); // PRINTS 0x22007FD7
dbgprintf("%d %x %x %x %x %x %x %x %x\n", st, bb[0], // PRINTS 0 1 0 0 0 1 0 0
bb[1], // (expected 1 0 1 0 1 0 1 0)
bb[2],
bb[3],
bb[4],
bb[5],
bb[6],
bb[7]
);
