其中需要理解的是APB1 和 APB2 的 区别, APB1 上面连接的是低速外设,包括电源接口、备份接口、 CAN 、 USB 、 I2C1 、 I2C2 、 UART2 、 UART3 等等, APB2 上面连接的是高速外设包括 UART1 、 SPI1 、 Timer1 、 ADC1 、 ADC2 、所有普通 IO 口 (PA~ PE)、第二功能 IO 口等。 端口复用和重...
In Single Conversion mode, the ADC does one conversion. This mode is started either by setting the ADON bit in the ADC_CR2 register (for a regular channel only) or by an external trigger (for a regular or injected channel), while the CONT bit is 0. Once the conversion of the selected...

The ADC is then stopped.连续转换模式 In continuous conversion mode, ADC starts another conversion as soon as it finishes one. This mode is started either by an external trigger or by setting the ADON bit in the ADC_CR2 register, while the CONT bit is 1. After each conversion:If a ...

The events generated by the general-purpose timers (TIMx) and the advanced-control timers (TIM1 and TIM8) can be internally connected to the ADC start trigger and injection trigger, respectively, to allow the application to synchronize A/D conversion and timers. 2.3.27 DAC (digital-to-...
