UCOSIII支持STM32F302吗？

请问stm32f302和stm32f103的ADC除了stm32f103有2个ADC（ADC1和ADC2），stm32f302只有1个ADC外，在使用ADC+DMA采样

我们正在对 STM32F302 芯片进行编程并遇到“无法获取核心 ID”故障。

stm32F302的标准库里面没有扫描模式，也没有看见哪里可以使能多通道啊？

我在调试stm32f302时，能够用软件触发AD转换，但是改用TIM4的TIM4_CC4 event就是不能触发AD转换，请问stm32f10x中的触发ADC

2018-10-31 09:56

在调试stm32f302时，由于要用到TIM1的CH2（PA9）和CH2N产生互补的PWM，但是Usart1(用的PB6和PB7)、Usart3(用的PB10和PB11)影响TIM_CH2引脚的输出，为什么会出现这样，求高手帮忙解答，谢谢

因为采样多个通道的AD转换，所以我用了ADC+DMA的方式进行的，定时器TIM4的上升沿触发AD转换（定时50us转换一次），但是始终无法进入AD转换完成中断中，求各位高手帮忙分析是什么原因导致的，谢谢。程序如下：void NVIC_Configuration(void){ NVIC_InitTypeDef NVIC_InitStructure; /* EnableADC1 DMA1_Channel1 Interrupt */ NVIC_InitStructure.NVIC_IRQChannel = ADC1_IRQn;

STM32F302的PB8作为UART3的RXD连接串口模块。现在问题是： 1、DEBUG模式下，UART3能正常接收。 2、正常运行模式下，UART3无法接收。 3、上电后手动复位，UART3可以正常接收。 这是什么原因啊，请指教
