电机的GPIO口的初始化,通过调用库函数RCC_APB2PeriphClockCmd[1],使能RCC_APB2Periph_GPIOA/RCC_APB2Periph_GPIOB端口时钟,而由于需要重映射,所以使能AFIO时钟RCC_APB2Periph_AFIO,之后通过复用推挽输出GPIO_Mode_Out_PP来将GPIO进行输出,输出到L298N的IN1～IN4,这里有两个电机,所以初始化了8个引脚,分别为PB...

Encoder :编码器 Button :按键 在移植时,不要搞错了输入设备的类型,否则 LVGL 无法对输入作出响应。 LVGL 对输入设备的接口全部存放在lv_port_indev.c及其头文件中。接下来以触摸屏为例介绍输入设备的移植,不同设备的 API 有一定区别,在移植时请以官方文档为主。
• Programmable digital glitch filter • Encoder mode (LPTIM1 only) Infrared interface (IRTIM) The STM32L451xx includes one infrared interface (IRTIM), which can be used with an infrared LED to perform remote control functions. It uses TIM15 and TIM16 output channels to generate output ...
and looking through an example of someone using the driver: https://petoknm.wordpress.com/2015/01/05/rotary-encoder-and-stm32/. Obviously, I do not want to use a HAL sensor, but this is the closest example I can get to someone using the advanced features of the timers. ...
The PWM signal generator exists with either 1 or 2 channels. In the case of 2 channels, it is a synchronous generator that can be used to control motors or to simulate signals from a quadrature encoder. The frequency is set the same for both channels. You can also set the shift separate...
