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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Any suggestions as to why power down, then reconnect debugger (JLINK pro) is clearing the TAMP registers to 0?Device is STM32L4P5The clock source seems to be present, it doesn't enter the if statement if (LL_RCC_GetRTCClockSource() != LL_RCC_RTC...
I'm working with the STM32U575 and using all four i2c blocks. My i2c code is interrupt driven.I can't find the right way to check which i2c block trigered the interrupt, suggestions please? void HAL_I2C_AddrCallback(I2C_HandleTypeDef *hi2c, uint8_t d...
Hello,I am fairly new to STM32 (and ARM MCUs in general), and I need a bit of help with DMA/MDMA transfers.I am using an STM32H747 dual core MCU and I intent to do some high-speed data sampling on the ADC (currently ~3 MSPS, going to 7-ish MSPS in th...
I followed this tutorial and I'm able to transmit UDP packets from my nucleo board to my computer. I've configured the code to use lwIP without freeRTOS. I'm trying to receive packets on my board over Ethernet by setting up a callback and it never en...
Dear all,I'm struggeling to get FDCAN2 working on my board. I also use FDCAN1 - which is working pretty good.For FDCAN1 I selected the RxFifo0 and for FDCAN2 I selected RxFifo1.But for some reasons, I dont get the callback for HAL_FDCAN_RxFifo1Callba...
I decided to replace the STM32F105 with the STM32G0B in my project.I have problems setting up FDcan.The STM32F105 had an “automatic bus-off management” setting, but the STM32G0B does not! This feature is enabled by default, how can I disable it? So t...
Hello, I have never used STM before and I am trying to choose a product, but I cannot buy and try each of them due to their prices. I am doing high-frequency work and I need a screen. STM32H735G-DK is a suitable board for me. However, there is a que...
Why the uart stops working on stm32h755 device once the core clock has been modified and code has been generated using cubemx. It comes with a BSP code for serial communication (which i tried seperately) , that is also not working once the core clock...
Hello all, I have to develop an application with a 7 inch screen driver SSD1963,for the choice of cpu. I'm deciding between an STM32H7B3 and STM32F7xx, on the card I need RAM for screen storage,touchscreen management, communication with an FPGA in SP...
Hello, everyone. I'm trying to use an STM32F103C6 to toggle some pins once per second. To this end, I have set up the RTC "seconds" event to fire on the appropriate interval.When busy waiting until the `SECF` bit of `RTC_CRL` is set, it works just fi...
