Has anybody worked with MAX31865 PT100 sensor chip. I have a module with that chip on a STM32F746 board and SPI bus gives me only zeros. Local loop MOSI->MISO works. The chip doesn't look very complicated but I get nothing out off it. The module has ...
In our product we will be placing one of 3 different processors. I have developed code to determine this by evaluating the registers for the peripherals, but I'm wondering if there is another way.I've been looking at the DBGMCU_IDCODE register. And o...
Hi!I'm working in a project that uses flash memory to store calibration data. At the first power on (before writing data in flash) everything works fine. After calibration, if I turn off the board and turn on again, my USART2 stops working (only send...
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 ...
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...
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...

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...
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
