Quadrature encoder interface timestamping

Hi,I'm using the STM32G474 in dual BLDC driver application.I'm operation the encoder interface at X4 mode. For RPM calculation I would like to time stamp every transition event i.e. encoder count + timestamp.Timers in use: TIM1/8 - PWM, TIM2/3 - hall...

I am interfacing Spi Flash AT25SF041 with STM32f030RC . while Debugging, i checked that SPI_I2S_FLAG is not able to SET.

 if ((SPIx->SR & SPI_I2S_FLAG) != (uint16_t)RESET) {   /* SPI_I2S_FLAG is set */   bitstatus = SET; } else {   /* SPI_I2S_FLAG is reset */   bitstatus = RESET; } /* Return the SPI_I2S_FLAG status */ return bitstatus;

USART prints junk after initializing the HSE clock (HAL_RCC_ClockConfig)

Hello,I am getting junk printed on the USART after initializing HSE clock. I had USART output at every single line and figured out that up to "HAL_RCC_ClockConfig" everything is ok and junk is printed right after executing this line. Also made sure t...

Why CubeMX use so many memory? I create the blink test from Stepbystep on NUCLEO-L011 with default settings (UART disabled). When I compile the project, it takes 77% of RAM and 33% of Flash.

There is somthings wrong in settings of my CubeMX?There is some optimizzatione that I can do?If I don't use CubeMX ( and so I don't use HAL), there is another libraryes that I can use in order to manage the MCU without managing register ?Thanks.

Stm32g03 series MCU occasionally enter HardFault_Handle() when writing flash

2 Chips with Different i2C Address on same I2c Bus , here how to ensure which i2c data is recieved? If any example for stm32f072 please share . Thanks , Rohit

SMT32_L4 non multiplexed asynchronous RAM IS61WV102416BL addressing issues

Hello everyone,For a university Project we are using a STM32L4 MCU together with the  IS61WV102416BL non multiplexed asynchronous SRAM. I followed the Application note which can be found at:https://www.st.com/resource/en/application_note/dm00228015-u...

STM32 application split up

I'm working on an STM32L432KCU microcontroller. I want to develop two applications on the same MCU:An "OTA" app. This would load first. It uses a cellular modem to check for, and download firmware updates, and overwrite the existing application. Othe...
