Info

Embedded CE 6.0 standard application program interface definition, DevKit8500D/A only expands interface definition of GPIO based on standard API. Please refer to the CD\wince_6\app for the application program representatives that control the status of LED through GPIO pin. Please check relative Help documents of MSDN Windows Embedded CE 6.0 API for Windows Embedded CE 6.0 standard application program interface definition. There are some use routines of standard API in the chapter GPIO Application Program Development Case for reference of users. Some interfaces exported by drivers can only be used by drivers; the application programs have no permission to call them. 4.7.2 GPIO application program interfaces and examples GPIO device name is L"GIO1:", corresponding device IOCTL code includes: IOCTL Code Description IOCTL_GPIO_SETBIT Set GPIO pin as 1 IOCTL_GPIO_CLRBIT Set GPIO pin as 0 IOCTL_GPIO_GETBIT IOCTL_GPIO_SETMODE IOCTL_GPIO_GETMODE IOCTL_GPIO_GETIRQ Operation example is showed below: 1) Open GPIO device pin Read GPIO pin Set the working mode of GPIO pin Read the working mode of GPIO pin Read the corresponding IRQ of GPIO HANDLE hFile = CreateFile(_T("GIO1:”), (GENERIC_READ|GENERIC_WRITE), (FILE_SHARE_READ|FILE_SHARE_WRITE), 0, OPEN_EXISTING, 0, 0); 2) Set read the working mode of GPIO DWORD id = 0, mode = 0; 3) Set the working mode of GPIO: DWORD pInBuffer[2]; pInBuffer[0] = id; pInBuffer[1] = mode; 92
DeviceIoControl(hFile, IOCTL_GPIO_SETMODE, pInBuffer, sizeof(pInBuffer), NULL, 0, NULL, NULL); 4) Read the working mode of GPIO: DeviceIoControl(hFile, IOCTL_GPIO_GETMODE, &id, sizeof(DWORD), &mode, sizeof(DWORD), NULL, NULL); "id" is GPIO Pin number, "mode" is GPIO mode, including: Mode definition GPIO_DIR_OUTPUT GPIO_DIR_INPUT GPIO_INT_LOW_HIGH GPIO_INT_HIGH_LOW GPIO_INT_LOW GPIO_INT_HIGH GPIO_DEBOUNCE_ENABLE Description Output mode Input mode Rising edge trigger mode Falling edge trigger mode low level trigger mode high level trigger mode Jumping trigger enable 5) The operation of GPIO Pin DWORD id = 0, pin = 0; 6) Output high level: DeviceIoControl(hFile, IOCTL_GPIO_SETBIT, &id, sizeof(DWORD), NULL, 0, NULL, NULL); 7) Output low level: DeviceIoControl(hFile, IOCTL_GPIO_CLRBIT, &id, sizeof(DWORD), NULL, 0, NULL, NULL); 8) Read the pin state DeviceIoControl(hFile, IOCTL_GPIO_GETBIT, &id, sizeof(DWORD), &pin, sizeof(DWORD), NULL, NULL); "id" is GPIO pin number, "pin" returns to pin state 9) Other optional operation Read the corresponding IRQ number of GPIO pin DWORD id = 0, irq = 0; DeviceIoControl(hFile, IOCTL_GPIO_GETIRQ, &id, sizeof(DWORD), &irq, sizeof(DWORD), NULL, NULL); "id" is GPIO pin number, "irq" returns IRQ number 10) Close GPIO device CloseHandle(hFile); 93
