Resolved! Error with STM32CubeMx 6.11.1

Hi,I'm working on a STM32H755BIT6 with a custom PCB layout, which uses direct SMPS supply hardware configuration.I'm migrating an existing Keil project which was created with STM32CubeMx 6.7.0 to STM32CubeMx 6.11.1 and I discovered that the option PW...

OTP readable by debugger while RDP set to 1

OTP portion of FLASH is a valuable asset in some STM32 families and represents a convenient place to store things like security keys. For this, it is desirable - and, as it's part of FLASH, also quite logically expected - that setting read-out protec...

ADC Input protection

I will be using 16 channels of STM32 ADC and I would like to protect them against overvoltage and ESD (those will be used as device inputs and unwanted situations can happen), my initial thought was to use a Zenner diode array and current limiting re...

STM32H743 pwm interrupts with high frequency

Greetings!I generate periodically a 10MHz PWM signal of 8 pulses. The PWM signal has high polarity so the first edge is falling. I need to generate an interrupt/event on the rising edge that'll signal DMA to move data from a GPIO IDR to a data buffer...

Standby mode and wakeup issues using wakeup pin

Hi i am working with stm32l051c8t6 , i am using wakeup pin 1 to wakeup from standby mode, weather is that possible to make the wakeup pin should act as wakeup pin and also as external interrupt, it should wakeup when an external interrupt is detected...

Resolved! I2C1 problem in STM32F401 with LSM6DSLTR

Hi,I have custom developed board that uses STM32F401RCT6TR as MCU. I have LSM6DSLTR IMU sensor on the board and MCU is communicating with IMU using I2C1 channel (PB6 and PB7). I also have 2.4" screen (ILI9341) that displays IMU values and external EE...
