Resolved! CAN-XL controller on STM32 MCUs
Hello,are we going to see CAN-XL controllers on a STM32 MCU anytime soon, or will ST only feature them in automotive MCUs for the foreseeable future?I would really need CAN-XL on a general purpose MCU for an upcoming project, where CAN-FD bandwidth w...
Resolved! STM32F407 I2C Addressing Problem
Hello!I have a new project with a STM32F407VET6 and a STM32F103xxx over a RJ45 Jack with I2C.i worked a lot of time with I2C EEPROMs and it works fine, but my communication between the 2 STM's are horrible, or i am too confused.i found the tutorial o...

Hello friends, i have the following setup:STM32H725ZGT6 on a selfmade board. STM32 CubeMX (default program with HSI clock and without any other peripherals). Keil µVision 5.23ULINK2 Debugger problem:I can program the controller ("verify successfull" ...
STM32U5 wakeup from stop mode with LPUART
Hello.I'm trying to wakeup the STM32U5 controller (U575ZI Nucleo board) when a byte is received using the LPUART.I'm using the LSE clock for the LPUART. Without entering the stop mode, the LPUART interrupt is triggered whenever a byte is received. Th...
If the bootloader will enter system ROM bootstrap first when using flash mode to boot in stm32f103
When I downloaded applicaton into flash, I found that it will respond my cmd code if I send cmd code immediately after NRST changing from 0 to 1.If although I choose 'Boot0(pin) = 1和Boot1(pin) = 0' to flash mode, the stm32f103 will also enter system...
