stm32l452re two ADC with DMA to capture 512 samples of each channel in parallel mode how to.
ADC_CommonInstructure.ADC_Mode = DC_DualMode_RegSimult-----what #iclude should point to?

Can NAND flash be used with STM32L475VGT6
I want to used NAND Flash with QSPI interface in STM32L475VGT6. Its not clear in the datasheet if NAND can be used on one page NAND driver shows up on block diagram and another one under the revisions of the part it says NAND has been removed.Can you...
STM32 Confusing users with description of Vref and VDDA
Hi,in my opinion there is some confusion in description of VREFINT_CAL and VREFINT_DATA to determine VDDA.My opinion: One determines VREF, not VDDA. One does not need to know VDDA in respect to measured values by ADC. One must know VREF (no matter if...
ADC Sampling Without Any Delay For 1 Minutes
I need to save adc data for 1 minutes. I am using ADC interrupt for 2651 sample per second. I have 2 buffer on adc interrupt. In main, in the while section if flag is 1 i am writing adc1 buffer values to sd card with dma. If flag is 2 i am writing ad...
Why does the STM32F413 Discovery kit not have a CAN bus interface?
The processor has three CAN ports and is the main reason I would want to use the discovery kit. Is there a different one available that uses the STM32F413ZHx processor I should be trying to use?
How to handle SPI DMA (50Mbits/s) and While() loop?
Hello!I use SPI DMA (NSS always down) communication between 2pcs H743ZI.Everything work fine, till I don't change SPI speed to higher frequency (6MBits/s)It seems like, the DMA interrupts don't let enough time for While() to run.EXAMPLE:... uint8_t p...
STM32F334 & SPI Modes
Hi,The ILI9341 display https://cdn-shop.adafruit.com/datasheets/ILI9341.pdfas on Page #35/233, is it using SPI MODE:3 ? Can someone clarify ?Slightly confused with the timing diagram for the 4 line Serial interface and hence my question.I am trying t...
With MDMA, do you have to follow AXI/AHB 4/1k cross-boundary limit with bursts ?
I understand AXI and AHB have limitation that burst transfers cannot cross 4k/1k boundary.I can see this explained with DMA1/DMA2, but not with MDMA. Are you still required tofollow this rule with MDMA ?The other question that puzzles me: is it requi...
Hi I would like to use a COMP to do the following: 1) clear the output of a PWM (TIM2) 2) keep the original off time .
ie: due to 1st request: dont finish a full PWM cycle, but make the PWM think that the cycle will end at the time that OUT was forced to low+ duty low time (shortening the cycle time).1st request was easy: I've connected COMP to TIM2_ETR.2nd request...
STM32F407VET USART example
Hi community, I'm searching a USART example , STM32F407VETFirst, I create code by using STM32CubeMX. I has try it but it is too hard to use that. I felt 'HAL UART' example of length of the array that receive and send , has limited. (or need more b...
