Compilation seems to fail when using the wonderful CapSense library.
Is there any port available for Arduino Zero?
Maybe you're using ancient code. Long ago, it was renamed to CapacitiveSensor.
I know CapacitiveSensor compiles, but (probably) doesn't work on Zero, because I'm the maintainer of that library. See this in the code.
#elif defined(__SAMD21G18A__)
// runs extremely slow/unreliable on Arduino Zero - help wanted....
#define PIN_TO_BASEREG(pin) portModeRegister(digitalPinToPort(pin))
#define PIN_TO_BITMASK(pin) (digitalPinToBitMask(pin))
#define IO_REG_TYPE uint32_t
#define IO_REG_ASM
#define DIRECT_READ(base, mask) (((*((base)+8)) & (mask)) ? 1 : 0)
#define DIRECT_MODE_INPUT(base, mask) ((*((base)+1)) = (mask))
#define DIRECT_MODE_OUTPUT(base, mask) ((*((base)+2)) = (mask))
#define DIRECT_WRITE_LOW(base, mask) ((*((base)+5)) = (mask))
#define DIRECT_WRITE_HIGH(base, mask) ((*((base)+6)) = (mask))
If anyone can figure out (and solve) why this isn't working on Zero, please submit a pull request on github.
Hi,
I know this is an old thread but I have found a library made by Adafruit which is compatible with ARM
devices (I tried it on a feather m0 express and responded well). it's called Adafruit_FreeTouch.
Is there any way to mix both? I kinda like the CapacitiveSensor library better.
