Working with SW4STM32 Workspaces, what are the RULES, why PROPERTIES won't show the present WORKSPACE?
I am new to STM32F products and SW4STM32 Development Tools including CubeMX. I also own a STM32F303RE Eval Brd. While working with SW4STM32 (IDE) I created a WORKSPACE; part of the initial opening. Also, the INITIAL install of STM32Cube_F3 included t...
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?
Resolved! Cannot debug and download flash on STM32H753 eval board with Keil
Dear experts,Any hints what can be the problem?I have STM32H753I-EVAL2 just out of box, no changes made.https://www.st.com/en/evaluation-tools/stm32h753i-eval.htmlBuilt an example app with Keil MDK. If it matters it is LwIP_HTTP_Server_Raw.Keil sees...
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...
