Resolved! Which OCTOSPI pins can be used as MOSI and MISO in single mode?
It is written in the STM32U575/585 reference manual (see below) that the data is sent to the external device over the SO(IO0) signal and that The data received from the external device arrives via SI(IO1). Now, SO is known as Slave Out but here it i...
I2S clock strobing
The stm32u5xx_hal_sai.c sets up the I2S clock strobing like this:static HAL_StatusTypeDef SAI_InitI2S(SAI_HandleTypeDef *hsai, uint32_t protocol, uint32_t datasize, uint32_t nbslot) { HAL_StatusTypeDef status = HAL_OK; hsai->Init.Protocol ...
clock setting, STM32H750
Hello,I have two different clock setting and only one of them works - but I have no idea why?The only difference is the PLLM and PLLN value: RCC_OscInitStruct.PLL.PLLM = 25; // 5 NOT OK RCC_OscInitStruct.PLL.PLLN = 432; // 160 NOT OKWould appreciate ...
Hardware reset need after programming to lower current consumption.
When I program to my stm32 MCU, I need to hard reset to lower the current consumption. I mean, after I programmed the MCU, the board consume 580uA. Then I do a software reset via NRST and still had the same current consumption. Then I do a hard reset...
How to configure RTC to work in wakeup interrupt
Hi, I am new to stm32 controller and trying to do RTC using baremetal. I like to wakeup my rtc in a second interval using wakeup interrupt. How can we configure the registers for the same.

STM32G431 Break input for PWMs
I am generating two PWMs with TIM1 CH1 and CH2 .I want to stop the PWMs when Break input is present. I have configured the STM32 Break input in the STM32cubeIDE and able to stop the PWMs when Break input is HIGH(3.3v).I needed the reverse way now lik...
