Hi All,My STM32F0 happily makes multiple channel ADC conversions and transfers them using DMA. However, when I flick the I2C into Fast Mode Plus mode (1Mb/s), there's no ADC conversions or transfers. It actually generates a DMA overrun, but there a...
ADC_CommonInstructure.ADC_Mode = DC_DualMode_RegSimult-----what #iclude should point to?
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...
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...
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...
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?
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...
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...
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...
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...
