Hello, after I upgraded my ubuntu STM32CubeIDE from 1.14.0 to 1.16.0 I am getting the IDE menus messed up, menu fonts messed up and some portions of the screen are black. Previous version 1.14.0 (and respective toolchain) did not have any problem.My...

Hello,my goal here to understand the TIM channel output behavior in different situations between generating one-pulse. Ultimately I need to make sure that I have a predictable output "0" level output at all times if not generating pulse.I am using ST...

I am using STM32H7 General Purpose Timers TIM2, TIM3, TIM4, TIM5 and their respective external trigger ETR using combined RESET and TRIGGER modes and I am configuring and starting Channel4 for each to generate One-Pulse output . All the configuration...

Hi, What are the revisions of the STM32F411CEU6 chip?The ERRATA doc from STM mentions only revision "A" . Are there other revisions?I received board with revision "1" .

I am coding STM32H743 MCU with CubeMX generated library.I have 1 SPI Master and 1 Slave. Both configured for a full SPI with both lines of Tx and Rx.Master is calling blocking HAL_SPI_Transmit() or HAL_SPI_Receive() but never simultaneous HAL_SPI_Tra...

Jan, please confirm (or deny) the following detail: If pin designated as a channel output for GP timer is disabled and GPIO setting for that pin is neither pull-up or pull-down, then is that pin configured as a default GPIO input ? High impedance?

Thank you Jan, although you did not explicitly state that my last suggested solution will indeed guarantee "0" level at the output channel pin whenever channel is disabled but if I understood correctly all your information , you proved this will work...

Thank you Bob, that will do but too many reconfigurations of the same pin... Wouldn't this give the same result if simply choose the channel output GPIO pin "pull-down" in configuration CubeMX for that timer ?My understanding is that this option is s...

I just realized that I can help myself to find of fix the problem if I pull-down the TIM13 channel output in the channel setup. I guess probably if TIM abandons the control of the output pin (switches from alternate TIM function to GPIO...input or ou...

Hi Bob, I am in the process of re-designing our board after the not-fully-understood circuits burn . It is important to fully understand the designed behavior of the output channel pin otherwise it's even hard to catch or understand the oscilloscope ...

After upgrade of STM32CubeIDE to 1.16.0 IDE screen messed up

What is the TIM13 channel pin output state in PWM mode when Counter=0 ?

General Purpose Timers: what are the options for One-Pulse slave mode trigger?

STM32F411CEU chip Revision Codes ?

HAL SPI library: Does Master's single call to HAL_SPI_Transmit() always trigger Slave's both HAL_SPI_RxCpltCallback() and also HAL_SPI_TxCpltCallback() ?
