I am starting a product design tentatively using the STM32F072RBT6.I want to determine how soon the CTS input must go low to prevent the USART from transmitting the next byte.Even informed opinion would be appreciated; but a reference to documentatio...
Hello,I'm trying to work with the ADC of the STM32L433 microcontroller. The Reference manual (RM0394) on page 448 it says : The following formula gives the actual VDDA voltage supplying the device:VDDA = 3.0 V x VREFINT_CAL / VREFINT_DATAWhere can I ...
Hello,I will use stm32g473VC ADC2 working together with DMA.I configure ADC2, Input3 at Pin PA6 and DMA2 Channel1 to read 100 Samples from ADC after Start.At first call after cpu reset I receive the expected result:ADC:Value 4034 for Items 0->99, as ...
Hello,I have designed a PCB with 3 STM32H725VGT6 MCUs, and assembled them according to my schematic:(sorry for this resolution, this is from a converted pdf)All 3 MCUs are the same, from this schematic.R5 and R2 are just 0R jumpers to select the boo...
Looks to me like the FDCAN peripheral has a few registers that are marked 'r' when they are likely 'rw' in the RM. They are the registers that configure the size of the FDCAN messages. This isn't blocking my work; only thought the ST team should know...
Trying to implement a composite HID device on STM32F042 (or maybe STM32F072 as both Flash and RAM usage seem insane), starting from the MX mouse middleware. After much scratching around it's finally working as a mouse and keyboard and I now need to a...
Hi I have Windows 10 with all windows updates . Antivirus is disabled.When i try to install the stm32 st-link utility 4.6.0 it starts to install but before there should be device driver installation wizard i get a msg But i dont know what block this ...
Posted on August 07, 2013 at 21:21 I'm confused about the FIFO error flag (FEIF) when I set up DMA for direct mode transfers. As I understand it, in direct mode the FIFO is disabled. But for some reason, if I enable the FE interrupt in the DMA_S...
Hi!I'm an EE designing a PCB. Referencing the datasheet: https://www.st.com/resource/en/datasheet/stm32l412k8.pdfSection 7.4 on page 178, UFQFPN48, the Exposed Pad (EP) says that it should be connected to GND.Section 7.6 on page 184, UFQFPN32 (the ch...
Hi,i'm trying to upload my firmware with FDCAN system bootloader in STM32H563.As this article(https://community.st.com/t5/stm32cubeprogrammer-mcus/fdcan-programming-support/td-p/199854) says that ST link debugger and STM32 cube programmer don't suppo...
