hi all,
i am using PART_TM4C1237H6PZ controller, i build code on ccs it is working fine,but when i tried the same code on keil it is not working. I am not getting interrupt on USB. my USB configuration is as bellow.
USBStackModeSet(0, eUSBModeForceHost, 0);
SysCtlPeripheralEnable(SYSCTL_PERIPH_USB0);
// // Configure the required pins for USB operation. // GPIOPinConfigure(GPIO_PF4_USB0EPEN); // GPIOPinConfigure(GPIO_PF5_USB0PFLT); // GPIOPinTypeUSBAnalog(GPIO_PORTB_BASE, GPIO_PIN_0 | GPIO_PIN_1); //id vbs GPIOPinTypeUSBDigital(GPIO_PORTF_BASE, GPIO_PIN_4 | GPIO_PIN_5); //- GPIOPinTypeUSBAnalog(GPIO_PORTJ_BASE, GPIO_PIN_0 | GPIO_PIN_1); //dp dm
// // Configure SysTick for a 100Hz interrupt. // SysTickPeriodSet(SysCtlClockGet() / TICKS_PER_SECOND); SysTickEnable(); SysTickIntEnable();
// // Enable Interrupts // IntMasterEnable(); // // Initialize the USB stack mode and pass in a mode callback. // USBStackModeSet(0, eUSBModeHost, ModeCallback);
// // Register the host keyboard drivers. // USBHCDRegisterDrivers(0, g_ppHostClassDrivers, g_ui32NumHostClassDrivers); USBHCDInit(0, g_pui8HCDPool, HCD_MEMORY_SIZE); USBHCDPowerConfigInit(0, USBHCD_VBUS_AUTO_HIGH );
// // Open an instance of the keyboard driver. The keyboard does not need // to be present at this time, this just save a place for it and allows // the applications to be notified when a keyboard is present. // g_psKeyboardInstance = USBHKeyboardOpen(KeyboardCallback, g_pui8Buffer, KEYBOARD_MEMORY_SIZE);
