以编程方式将UART TX转换为GPIO？

请参阅此线程：在运行时将SWD引脚更改为GPIO
但是，总结一下：
“可以使用适当的PixStReDeVelDead（）API在任何时候设置PIN的驱动模式。”@ USER13138899。



     以下为原文
  See this thread: Change SWD pins to GPIO at runtime
But, to summarize it here:
"You may set the drive mode of a pin at any time using the appropriate Pin_SetDriveMode() API." @user_1377889

谢谢，我不清楚如何处理我的问题。我读了UM RE PixStReDeValMeDe（），仍然不理解如何以实际的方式使用它。
Pi11yDm强驱动
Pix1MyOdOHYI开漏，驱动高
Low的开沟排水
Posi11DMSRESUPUP电阻拔出
Posi11MdReSydWNN电阻下拉
Posi11MdReSyxUPDN电阻拉/升
Pix1MyDig-Digi-Hiz高阻抗数字
Pij11MdAlGaZnHiZ高阻抗模拟
我假设Pix11dMyStand参数实际上是Pix5IsHistor，但是如何通过/选择端口？一旦更改为GPIO如何将端口/引脚返回到UART？
你能给出一个代码例子吗？
-将P3.5设置为GPIO
-驱动P3.5低
-等待1秒
-将P3.5设置为UART TX
谢谢你的帮助

  Thanks, the link was not clear to me how to address my issue. I read the UM re Pin_SetDriveMode() and still not understanding how to use this in a practical manner
Pin_1_DM_STRONG Strong Drive
Pin_1_DM_OD_HI Open Drain, Drives High
Pin_1_DM_OD_LO Open Drain, Drives Low
Pin_1_DM_RES_UP Resistive Pull Up
Pin_1_DM_RES_DWN Resistive Pull Down
Pin_1_DM_RES_UPDWN Resistive Pull Up/Down
Pin_1_DM_DIG_HIZ High Impedance Digital
Pin_1_DM_ALG_HIZ High Impedance Analog
I assume the parameter PIN_1_DM_STRONG would actually be PIN_5_STRONG, but how do pass/select the port? Once changed to GPIO how to return the port/pin back to uart?
 
Can you give a code example;
-Set P3.5 to GPIO
-Drive P3.5 low
-Wait 1sec
-Set P3.5 to UART TX
 
Thanks for your help

由于E.PrATT指向正确的方向，我发现了与我同样要求的重新配置线程。我能成功；
-将P3.5（Tx）设置为GPIO=
//重置所需的位来制作GPIO，请注意将RX引脚更改为GPIO。
CyrgStIrgRe32（CyReGythHsiMouthPosier-Sel3，CythGETYRG32）（CyrGrGyHsiMouthPurtHel-Sel3）和0xFF0FFFF；
/下一个设定的期望模式
UARTHTXXSEDRIVEVMODED（UARTHARTXXDMSYORM）；
-驱动器P3.5低=
/按需要设置驱动器级别
UARTHARTXX写（0）；
-将P3.5设置为UART TX=
//设置需要的比特来恢复GPIO返回UART
//在GPIO改变之前，CyrGrxHsiMoxPurtHel-Sel3每单位容量为0x90099万h。
CyrGeStIrgRe32（CyReGythHsiMouthPurth-Sel3，CygGeTyGeR32（CyrgsiHsioMyPurth-SEL3）0x0.99万）；

  Thanks to e.pratt pointing me in the right direction I found reconfigure thread that has the same requirement as myself. I'm able to successfully;
-Set P3.5 (TX) to GPIO =
//reset required bits to make GPIO, note this changes RX pin to GPIO as well
CY_SET_REG32(CYREG_HSIOM_PORT_SEL3,CY_GET_REG32(CYREG_HSIOM_PORT_SEL3) & 0xFF00FFFF);
//next set desired mode
UART_tx_SetDriveMode(UART_tx_DM_STRONG);
-Drive P3.5 low =
//set drive level as desired
UART_tx_Write(0);
-Set P3.5 to UART TX =
//set required bits to revert GPIO back to UART
//prior to GPIO change CYREG_HSIOM_PORT_SEL3 was 0x00990000 per cyfitter.h
CY_SET_REG32(CYREG_HSIOM_PORT_SEL3,CY_GET_REG32(CYREG_HSIOM_PORT_SEL3) | 0x00990000);
