<p>Created page with &quot;Set appointed pin as output pin. ==== Prototype ==== int32_t WINAPI VGI_SetOutput(int32_t DevType,int32_t DevIndex,uint16_t PinMask); ==== Parameter ==== &#039;&#039;&#039;DevType&#039;&#039;&#039;:Device...&quot;</p> <p><b>New page</b></p><div>Set appointed pin as output pin.<br /> <br /> ==== Prototype ====<br /> int32_t WINAPI VGI_SetOutput(int32_t DevType,int32_t DevIndex,uint16_t PinMask);<br /> ==== Parameter ====<br /> '''DevType''':Device type code. For detail, please refer to Device Type Definition Table.&lt;br&gt;<br /> '''DevIndex''':Device index number. Index number 0 indicates only one device is connected with computer. In case multiple devices are connected, set index number corresponding to the devices required to be openeded.&lt;br&gt;<br /> '''PinMask''':Pins need setting as output mode. In case the corresponding bit is 1, then the relative GPIO pin is set as output pin. E.g. when PinMask is 0x0001, set GPIO_0 as output pin. When PinMask is 0x0102, set both GPIO_1 and GPIO_8 as output pins. And other pins are not influenced by such settings.<br /> ==== Return code ====<br /> Program execution state. Parameter 0 indicates related function executes successfully. For other return codes' definition, please refer to Error Code Definition Table.<br /> ==== Example ====<br /> #include &lt;stdio.h&gt;<br /> #include &quot;ControGPIO.h&quot;<br /> int ret;<br /> ret = VGI_SetOutput(VGI_USBGPIO, 0, VGI_GPIO_PIN1 | VGI_GPIO_PIN8);if (ret != ERR_SUCCESS){<br /> printf(&quot;Set pin output error!\n&quot;);<br /> return ret;<br /> }</div>
