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...
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...
Hello,We are struggling for a while with bank2 access in continuous clock.We are using FPGA connected to bank2 in FMC bus.We work with FIFO access in FPGA (a single address for the FIFO)Single register access works fine, but with burst access there a...
i am using stm32L072I am using uart1 in the code I found that code doesn't works ,if i don't connect a usb to uart converter between PC and the microcontroller .When i connect usb to uart connector and reset microcontroller ,it starts working :wear...
