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...
Greetings!I am using the STM32U031 with STM32CubeMX HAL as an SPI Slave and would like to receive data that has variable length (max 50 bytes). I am using software NSS and my current approach is to start a DMA Rx/Tx transfer (using HAL_SPI_TransmitRe...
Hi,uc: stm32f446 I have a question regarding non standard word length over RS485.I need to receive next frame over RS4851 start bit, 16-bit data word, 2 stop bits, in total 19 bits.UART implementation allows to receive 8 or 9-bit data words.Could you...
Hello ST Community,I am seeking guidance on how to properly configure the VDD50USB and VDD33USB pins on our STM32 device when we are not utilizing the USB functionality. The explanations provided in the datasheet and application notes are somewhat am...
Issue Description: My code is divided into two parts, namely the APP area and the TRIM area. When I merge the code of these two areas together, there is no problem with programming through Keil. However, when I separate the code for these t...
I have made a custom pcb with STM32767ZIT6. To program it I use VCC, SWDIO, SWCLK, GND, NRST pins to plug in ST-LINKv2. I also have LED to check if code works. I use STM32CudeIDE to write code and configure the chip. I set one GPIO to be an output pi...
I'm applying ID masking for filtering in the FDCAN protocol, but it's not working. The sensor I'm using has an ID of 315. In the code, I've set it to only receive messages with an ID of 320, but it's also receiving messages with an ID of 315, which i...
Hello, I'm trying to use the RTC of my NUCLEO-L476RG including the sub-seconds feature. I've activated the RTC clock source in the .ioc and configured LSE as clock source (32.768KHz). I've set up an initial value to the RTC and I'm reading it out eve...
I am using a NUCLEO board with a STM32H7A3 MCU for lab classes in engineering. I am giving basic notions for the inner workings of most digital peripherals, so I am avoiding using HAL functions. Using basic CMSIS macros, we can use register names and...
Hi everyone,Help please,Im using CubeMX 5.0 with STM32F407 Disco board, I had activated the HSE clock to be the clock system with 168 MHz (HCLK on the clock tree of CubeMX).Im tryning then to get the CPU clock, ( to introduce it in the Basic systik m...
Good afternoon! Our university bought approximatively 9 or 10 B-L4S5I-IOT01A Discovery kits for lab/projects at Embedded Systems course. I found that for this board I have no examples. I installed 30 GB of software/support package on my laptop. On ST...
