Hello,
We have a MCB2300 Arm development kit. We want to use external interrupts and SD Card together. We have noticed that external interrupt pins are shared with SD/MMC interface. We futher noticed that when we try to use external interrupts and SD/MMC interface together we are unable to write any data to SD memory card.
Is yhere a way of overcoing this problem. Can we use external interrupts and SD/MMC module symultaneosly?
Thanks for your time Best regards.
/EINT0 isn't shared.
/EINT1 .. /EINT3 are shared pins so you get a collision.
But note that you also have access to pin-change interrupts for P0 and P2 giving you some alternatives to /EINT1../EINT3.
