STM32H735 HyperBus speed byte vs word (32bit) vs QSPI

Hello,I got my hands on a H735 Discovery Board which has an external "HyperRAM" (Infineon S70KL1281DABHI023) connected to OCTOSPI2.I need to use it in memory mapped mode, which is quite easily setup via HAL stuff (just switched to register setup to l...

I2C stops working with System Clock 168M on STM32F407

Hello,I'm working on a STM32F407 board, and communicating with 6 I2C sensors which are scattered on the 3 I2C interfaces with 400K clock. Everything is fine if the system clock is set to 40MHZ. When I'm trying to change the sys clock to 168M, all I2C...

Using stop mode with a nucleo-stm32l031

Hi,I would like to use the nucleo-stm32l031 to some low power tests. I'll try the NUCLEO-L011K4->PWR_STOP_RTC and also the NUCLEO-L031K6->PWR_STOP_RTC. Both example don't work on my NUCLEO-L031K board.The problem is that the MCU don't go in STOP mode...
