Function Sets pullup value when Port A, B, C are all in input mode.
Format void ioctl(int fd, SETGPIOVAL_LM, int *value[3]);
Parameter fd Handle to GPIO device(‚/dev/eddy_gpio‛)
mode Pointer to the buffer that stores the ‚pullup‛ value
of Port A, B, C.
Bit value 0 means Pulldown, 1 means Pullup.
Returns None
Notice Any value is ok for bits that are not set to be used GPIO
GETGPIOPUL_LM
Function Reads Read/Write status value for Port A, B, C
Format void ioctl(int fd, GETGPIOVAL_LM, int *mode[3]);
Parameter fd Handle to GPIO device(‚/dev/eddy_gpio‛)
mode Pointer to the buffer that will store the ‚pullup‛
value of Port A, B, C
Returns None
Notice
SETGPIOMOD_LA
SETGPIOMOD_LB
SETGPIOMOD_LC
Function Sets Read/Write direction for one of Port A, B, C
Format void ioctl(int fd, SETGPIOMOD_L?, int *mode[3]);
Parameter fd Handle to GPIO device(‚/dev/eddy_gpio‛)
mode Pointer to the buffer that stores ‚mode‛ value.
Bit value 0 means input, 1 means output.
Returns None
Notice Any value is ok for bits that are not set to be used GPIO
GETGPIOMOD_LA
GETGPIOMOD_LB
GETGPIOMOD_LC
Function Reads Read/Write direction for one of Port A, B, C
Format void ioctl(int fd, GETGPIOMOD_L?, int *mode[3]);
Parameter fd Handle to GPIO device(‚/dev/eddy_gpio‛)
