Hi everyoneI have a system that uses a STM32F205 to sample on a signal at 2MHz. I wanna generate a signal that indicates the sampling times of the ADC as im battling with some frequency differences in my system. Interrupts are sadly not an option as ...

Hi everyoneI was wondering if it would be possible to implement a DMA setup without interrupts that maintains two circular buffers for the same USART? I would like to save both the SR and DR register values in two separate circular buffers every time...

I dont doubt them per say but i doubt my implementation of them.As seen in the attached picture i get noise at the ends of my signal but not in the middle. This is despite the measured noise being uniform switching noise that persists throughout the ...

I do trigger the adc with a timer but only the start of the sequence. From the initial timer trigger the adc is in free running mode tuned to a sampling time of 2MHz through the clock tree.Havent been able to observe sampling time on the oscilloscope...

Used this thread to reorganize my thoughts about it and git it working. Heres my quick and general cookbook on it.init timer and DMA(Remember to select the correct DMA type in CubeMX)Call HAL_DMA_Start() with your parameters if you arent using captur...

Hey Bach I seem to be running into a similar error when configuring timer2 of an F205RG to update period and multiple pulse values(ARR, CCR1, CCR2). I too run into the issue of the DMA state not being configured correctly and staying at HAL_DMA_STATE...

Thought that might have been the case. Thanks for the help 

Is it possible to generate a signal that indicates sampling time of a ADC externally.

Can dual circular DMA buffer be implemented on a single RX USART?
