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...
Hi, I'm using a STM32L100RC discovery board and I'm trying to send/receive two words (string type) to/from another program not related to the MCU. Nevertheless, the Virtual Com Port (VCP) is not available on this device. Is it still possible to use t...
Hi,Are there any restrictions on reading OTP when the Flash LATENCY is configured for 0 wait states, and the AXI clock frequency / VOS are within the required range allowed for such?With an STM32H7A3 with SYSCLK configured to HSIDIV4 (i.e. 16 MHz), V...
I have a transmitter over USART and an STM32H7 receiving data. The transmitter always writes N bytes at a slow repetition rate, i.e. every 1 second or more.Once N data are received by the STM32H7, for example using interrupt, the function HAL_UART_Rx...
To give you an update to the LSE crystal oscillator startup issue with the STM32H743XIH6, we have made some more investigations and this is what we have found.There was a problem with the software, that we found. If we made a Backup Domain reset befo...
I am a new member, I am learning about UART data transmission of MCU STM32F411RE on a nucleon board. I have read and understood the function HAL_UART_Transmit. However, in this function, there is a part I don't understand. I don't understand the mean...
Hello everyone,I am trying to install STM32cubef3 patch v1.11.2 ,the zip file download from st web site, and I already installed STM32f3 v1.11.0, but when I use embedded software packages manager choose the zip file, it always display "Missing depen...
1. It is correct to read and write flash through command function when there is no memory mapping enabled（ flash:MX25R6435F ）2. After memory mapping is enabled, after accessing the address of 0x90000000, the MCU crashes and cannot recognize the chip....

Based on the info in the STM32 reference manual, I would have thought this code to start up the WWDG would work (after processor reset). // sets up the WWDG with a period of about 1 sec, no lower limit inline void StartWwdg() { LL_APB1_GRP1_EnableC...
