I would like to know if it is possible to generate a sweep signal (a sine wave with increasing frequency) using DAC with DIMA transfer and simultaneously sample it by ADC and store these ADC values in memory.To generate the sweep signal, I use TIM2 a...

I use STM32F407 Discovery board to generate analog signals using DAC with DMA transfer. The goal is to use both DAC channels to have two signals generated simultaneously. However, I cannot enable the DMA request for the second channel. After analyzin...

I am generating a sweep signal (a sine wave whose frequency increases over time) on STM32F4 Discovery board by using a look-up table and changing the Prescaler value of TIM2. Unfortunately, the transition from one frequency to another is not smooth a...

Thanks for the reply! Could you please specify which values should I populate into the DAC buffer so that the frequency would increase linearly? If I leave the update time, letting the clock frequency to be 1MHz for example, how it is possible to cha...
