For GPIOB in output state function will set output driver to drive "1"-high, "0"-low. ForGPIO in input state function will "1"-enable, "0"-disable weak pull-up on corresponding GPIOB pin.Parameters· set - Bits 0..7 of set parameter correspond to GPIOB0..GPIOB7 output statuses.· *get - Pointer to store current GPIOB output status read from SUB-20.· mask - Bit in set parameter will take effect only if corresponding mask bit is "1". With mask=0 function willonly read current GPIOB output status.Return valueOn success function returns 0. Otherwise error code.See alsoError CodesCompatibilityFW versionLibrary version0.2.7 or grater0.1.12.17 or grater3.7.7 Edge DetectorEdge Detector descriptionSUB-20 Edge detector module (EDGE) is capable to detect falling, rising or "any change" edge on the GPIOpins listed below.GPIO Header Pin GPIO Edge Number1 GPIO8 EDG02 GPIO9 EDG13 GPIO10 EDG24 GPIO11 EDG313 GPIO28 EDG414 GPIO29 EDG515 GPIO30 EDG616 GPIO31 EDG7Pulses on EDG7:0 pins wider than the minimum pulse width of 50ns will trigger edge detection. If enabled, theedge detection will trigger even if the corresponding GPIO are configured as outputs.Functionssub_edge_configsub_edge_read© 2013 xdimax.com rev 2.17
