gpio_partialremap1_tim3 是在某些微控制器(如STM32系列)中用于配置GPIO(通用输入输出)引脚的一种特定映射功能。STM32微控制器支持多种GPIO复用功能,允许GPIO引脚被重新配置为其他外设的输入/输出端口,比如定时器(TIM)、串行通信接口(USART)、SPI等。gpio_partialremap1_tim3特指对TIM3定时器进行部分重映射的功能...
A smart fan controller use a STM32 MCU to cooling a LED light . The controller have 3 main function. 1.A GPIO generate a 25KHz PWM signal to control the fan speed. 2.The fan speed increase with temperature increasing. 3.When the temperature over 80 degre
