STM32 MCUs Products

Hi everyone I need help understanding what I am doing wrong. I would like my buffers to work properly, but when I run the program my terminal starts sending all sorts of strange characters. I use stm32f411e-Disco

Nucleo-G071 + STM32CubeIDE has I2C working for one project but not others

I have a situation where I'm starting to work with the STM32CubeIDE and STM32 MCUs, and I've followed some tutorials with relatively positive success. However, I ran into an issue where I got I2C working on one project, but I cannot for the life of m...

Do we have to change our code for operation on a version of the STM32 with larger flash memory? We currently use STM32F103RCT7 but may need to use STM32F103RET7 for stock availability. Is this possible with the same firmware or do we need to change it?

In 'F407, bxCAN does not go to Bus-Off

In STM32F407, I have set bxCAN with CAN_MCR.ABOM=0 and CAN_MCR.NART=0. With the bus lines after transceiver (PHY) left open, after trying to transmit, transmitter transmits continuously forever, with CAN_ESR.LEC=0b011 for Acknowledgement Error (which...

Can SRAM1, SRAM2, SRAM3 be treated as one continuous memory region?

(This is regarding STM32H75x)SRAM1, SRAM2, and SRAM3 are separate in the memory map, but they are continuous - there are no gaps between them: Can they be treated as continuous with respect to the linker, for example:RAM_D2 (xrw) : ORIGIN = 0x3...
