用最新库玩转智林STM32开发板(之九)------在真彩屏上显示方向键的状态 [复制链接]

有智林板的可以把所有文件考到一个目录下边,工程非常简单只包括三个文件
main.C//主文件
TFT018.c//显示有关文件
STM32F10XR.LIB//这个文件在MDK目录下边很好找
智林开发板板载上,下,左,右,方向键,若直接按,就是OK,本程序只是设置好上拉电阻输入就行,
运行时可即时显示用户的按键,本例有HEX可直接下载到芯片里边

以下是主程序:

int main(void)
{
#ifdef DEBUG
  debug();
#endif
  /* System Clocks Configuration */
  RCC_Configuration();
  /* NVIC Configuration */
  NVIC_Configuration();

  /* GPIO Configuration */
  GPIO_Configuration();

  /* Time base configuration */
  TIM_TimeBaseStructure.TIM_Period = 0x5000;
  TIM_TimeBaseStructure.TIM_Prescaler = 0x00;
  TIM_TimeBaseStructure.TIM_ClockDivision = 0x0;
  TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;

  TIM_TimeBaseInit(TIM2, &TIM_TimeBaseStructure);
  /* Output Compare Toggle Mode configuration: Channel1 */
  TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
  TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
  TIM_OCInitStructure.TIM_Pulse =CCR3_Val ;
  TIM_OC3Init(TIM2, &TIM_OCInitStructure);

  /* TIM enable counter */
  TIM_Cmd(TIM2, ENABLE);
  LCD_Init();
  LCD_Clear_Screen(Blue);
