STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
We are working with stm32h743 and W25Q128JV We used to have 6 dummy cycles, but when USB is initialized we need to change it to 4.Than we tested another board and it was changed again to 2.Why? What is wrong
Hello I have some problems with an interruption on the STM32H7. I'm working on a project and i implemented a timer with two interrupts (OVF and CC1) and that worked. But after trying to implement HSEM that no working even with an old version. That'...
Hello,I am using STMCUBEMX 5.2.1 to initialize the configurations of my STM32F072RBT6. My application requires the use of i2c1 since i2c2 is already occupied on our board by a pressure sensor. However, it seems to me that i2c1 is not working (i.e. th...

I'm currently trying to setup a STM32F4DISCOVERY Board with the STM32F407VGT6 chip as a I2C slave. Somehow the controller doesn't send any ACK bit after the address was received. I've tried with the General Call function as well.Here is my initialisa...
Hello, I am using STM32F746 Discovery Board and want to write and read data to external flash memory . I gone through example code from STM. There is one function called QSPI_DummyCyclesCfg, I am not able to understand it completely./* Configure Vola...
Hello everyone!I'm want to use the internal reference voltage buffer of the mcu stm32g431kb as input with comparator, but when i checked the reference manual they say VEREFBUF must kept disabled because no VREF+ pin in 32 pin package!!I don't want th...

I am communicating with ad7730 (24bit adc) using atm32f103ZCT6. I try to read one of the registers of the adc but each time I receive a random wrong figure. The strange thing is that while debugging using serial wire (STLINK) everything is perfect an...
Hello,In my application I want to get the ADC voltage - waiting indefinitely until the operation completes. Will this code work ?while ( HAL_ADC_PollForConversion ( & hadc1 , 1000 ) == HAL_TIMEOUT );
