以编程方式在 WinCE 5 PCMCIA 插座上循环上电?
WinCE 5 驱动程序如何在其控制下循环 PCMCIA 插座上的电源?
我已经尝试过 pcmcia.dll 中的 CardPowerOff() ,但它没有实际上并没有切断电源。任何建议都会有帮助,但我对机制并不挑剔。
How can a WinCE 5 driver cycle the power on a PCMCIA socket under its control?
I have tried CardPowerOff() in pcmcia.dll, but it doesn't actually remove power. Any advice there would be helpful, but I'm not picky about the mechanism.

如果可能,实现它的机制取决于硬件/OEM。您必须去找您的设备 OEM,询问他们是否/如何在他们的硬件上完成此操作。我的猜测是,如果 CardPowerOff 实际上没有切断卡电源,那么 OEM 就没有提供完全关闭它的方法(我以前见过它们硬连线到电源)。
If possible, the mechanism to achieve it is hardware/OEM dependant. You're going to have to go to your device OEM and ask them if/how it might be done on their hardware. My guess is that if CardPowerOff isn't actually removing card power, the OEM didn't provide a way to fully shut it down (I've seen them hard wired to power before).
