Hello I am trying to make a simple application using emWin library which creates a button on LCD screen and if a button is pressed then turn on a LED diode but touchscreen is not responding to click. Can you tell me where do I make a mistake?
int main(void) { BUTTON_Handle hButton; /* STM32F4xx HAL library initialization: - Configure the Flash prefetch, instruction and Data caches - Configure the Systick to generate an interrupt each 1 msec - Set NVIC Group Priority to 4 - Global MSP (MCU Support Package) initialization */ HAL_Init(); /* Initialize LCD and LEDs */ BSP_Config(); /* Configure the system clock to 180 MHz */ SystemClock_Config(); /***********************************************************/ /* Compute the prescaler value to have TIM3 counter clock equal to 10 KHz */ uwPrescalerValue = (uint32_t) ((SystemCoreClock /2) / 10000) - 1; /* Set TIMx instance */ TimHandle.Instance = TIM3; /* Initialize TIM3 peripheral as follows: + Period = 500 - 1 + Prescaler = ((SystemCoreClock/2)/10000) - 1 + ClockDivision = 0 + Counter direction = Up */ TimHandle.Init.Period = 5000 - 1; TimHandle.Init.Prescaler = uwPrescalerValue; TimHandle.Init.ClockDivision = 0; TimHandle.Init.CounterMode = TIM_COUNTERMODE_UP; if(HAL_TIM_Base_Init(&TimHandle) != HAL_OK) { while(1) { } } /*##-2- Start the TIM Base generation in interrupt mode ####################*/ /* Start Channel1 */ if(HAL_TIM_Base_Start_IT(&TimHandle) != HAL_OK) { while(1) { } } /***********************************************************/ /* Init the STemWin GUI Library */ GUI_Init(); GUI_Initialized = 1; /* Initialize RTC and Backup */ RTC_Init(); /* Activate the use of memory device feature */ WM_SetCreateFlags(WM_CF_MEMDEV); /* Do the calibration if needed */ CALIBRATION_Check(); /* Start Demo */ hButton = BUTTON_CreateEx(20, 50, 219, 30, 0, WM_CF_SHOW, 0, GUI_ID_BUTTON0); BUTTON_SetText(hButton, "XXX"); BUTTON_SetFont(hButton, &GUI_Font8x15B_ASCII); GUI_Exec(); while (1) { if (GUI_GetKey()==GUI_ID_BUTTON0) { /* Led Off */ HAL_GPIO_TogglePin(GPIOG,GPIO_PIN_13); /* Stop while loop */ break; } }
