STM32H735 SDMMC Error FR_NO_FILESYS
I'm having trouble getting the on board SD card reader working properly. The board is the STM32H735G discovery kit. When attempting to mount the disc it comes back with error FR_NO_FILESYSTEM. A closer investigation shows that when reading the first ...
How to configure the Standard Peripherals Library for a STM32F098
Hi all:I have firmware for a STM32F072RBT6 that uses the Standard Peripherals Library.I am now considering porting the firmware to a different microcontroller from the family STM32F098. There are 3 of them: STM32F098CC, STM32F098RC and STM32F098VC, b...
CAN programming question
Hi !I'm new in the STM32 world ! So, sorry if my questions are stupid. I work on CAN with the example : FDCAN Classic Frame Networking.I want to know if in this example that I modified slightly, HAL_FDCAN_AddMessageToTxFifoQ(&hfdcan1, &TxHeader, TxDa...

STM32F7 How to design external oscillator
Hello,I have been trying for a while now to properly design the external oscillator for the STM32F722RE MCU.Until now, I don't find a clear answer with detail calcul.To design the oscillator, I use 3 documentations:stm32f722re.pdfcd00221665.pdf (AN28...
Resolved! How many PWM effective outputs does STM32G474RE have???
Hi all,Thanks in advance for your timeregarding the specific microcontroller STM32G474RE which has a total of 64 pins. How can I know how many of them can be used as PWM outputs???Thank you
Resolved! STM32F373 SDADC Analog input range
Hi, I have 50Hz sinewave with 660mVp-pk, should i connect this to SDADC analog input? It can measure negative cycle of the sinewave? i.e. If i configure SDADC as single ended zero reference mode then it can measure negative cycle of the sinewave?Na...
16 Bit SDADC is only giving 15 Bit value
I am running both SDADCs on a STM32373C-EVAL evaluation board. One of them is giving me the correct values from 0-65.535 but the second one is giving me 0-32.767 on the same voltage.I have configured them using the Cube IDE and Hal. They are set up e...
Correct settings for FDCAN in CAN2.0 Mode using a ST G431KB Microcontroller
Dear ST Community,I am trying to use the FDCAN peripheral of the G431KB STMicroelectronics Microcontroller.It is a project requirement that the FDCAN is used in CAN 2.0 mode (FDCAN_CLASSIC_CAN). FDCAN is backwards-compatible so thus far there's no is...
