I2C_frequency configuration

Hi,I would like to configure the I2C frequency based on the input clock frequency. Is there a specific formula to calculate the I2C timing values? Also, I would like to know whether this formula is applicable to all STM32 microcontrollers, or if it v...

Issues with interrupt priority handling

Hello,i have configured a timer interrupt an it seems like that interrupt preempt another adc interrupt. I configured the timer interrupt like that: NVIC_SetPriority(TIM1_BRK_IRQn, 2U); NVIC_SetPriority(TIM1_UP_IRQn, 2U); and the adc interrupt like t...

Resolved! STM32L011 bootloader cannot read SRAM

硬件不变的情况下,SPI+DMA 循环模式主机接收 采集电压异常,Normal模式却正常

用SPI+DMA驱动AD4001,用片选信号代替 CONV,采集一个正弦信号。Normalnormal正常,循环模式却不对,求大佬解答!!Normal模式下,每次在 HAL_SPI_RxCpltCallback 函数里面重新启动数据正常,能看到正弦变化规律                                 循环模式下数据就不对了,采集的同样一个交流信号,我在半传输完成回调里面查看,按道理后半部分的数据应该是正常的正弦变化才对,实际却不是,但是去采集直流时又是正常的。        ...
