Code Example

The following code example uses the SetPinDir function.

The SMK900.evi file used for this example can be downloaded at the bottom of this page.
/* Example Code
* GetPinDir/SetPinDir
*
* get pinId, val
* get valInit
*
* return valInit and
* if useParams
*	new dir of PIN
* else
* 	0x01 (new dir == val) or 0x00 (new dir != val)
* on 16 bits
*
* example VMExecuteCmd:
* cmd: 															   |pinId    |val
*		0xfb 0x0e 0x00 0x0c 0x00 0x0e [0x?? 0x?? 0x?? = macAdress] 0x00 0x00 0x01
* rsp: 	0xfb 0x0a 0x00 0x2d 0x00 0xe1 0x1e 0x01
