int X12_read_gpio(int CardId);

Parameters

CardId

Card identifier. Must be between 0 and number of cards minus 1.

Return values

State of GPIO

Notes

Reads state of GPIO pins: active input is low (when input is pulled down bit is set to 1).

X12_write_gpio

void X12_write_gpio(int CardId,int state);

Parameters

CardId

Card identifier. Must be between 0 and number of cards minus 1.

state

State of GPIO

Return values

None.

Notes

Sets state of GPIO pins: active output is low (output is pulled down when bit is set to 1).
