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...
Hello,we are having an issue on the STM32H730 ; we would like to have a Timer Capture triggered by the USB OTG SOF signal. This should be straightforward since the USB1_OTG_HS_SOF signal is connected to TIM2 ITR5. However, we never managed to have th...
Hi everyone,I'm currently working on an STM32 project where I want to communicate with an SMBus-compliant battery (address 0x0B) using I2C. I'm using an STM32F105 microcontroller and I'm setting up I2C on GPIO pins B6 (SCL) and B7 (SDA). I've encount...
Hi I am trying to generate interrupt every 100uSec using Timer-2 using stm32f103c8t6 blue pill. I have simply set the system clock to 72 MHz pre scaled the timer two by 72 time using 72-1 and setting counter period to 100. I have also enabled TIM2 Gl...
STM32G071R8 & M95160-WMN6TP EEPROMWe have the DMA SPI TX direction working but are having issues with the data that is being returned. Technically this is a read from the EEPROM but the command and read address are sent first. The EEPROM responds wit...
I have a project where VREFBUF outputs 2.0xxV correctly without intervention. I created a new project and I see VREFBUF output stuck at 0V, and I'm not sure what's causing the changed behavior. I inspected the VREFBUF_CSR register and I see ENVR=1 a...
I tried everything to send a simple wave through the DAC pin using HAL and STM32CubeIDE to configure the project. What I've checked that works: - Clock source- Trigger source- Output pin configuration- Built-in triangle and noise wave generation. I t...

Dear ForumIm using STM32 H755 ZI in the starter kit. I set the Timer 4 for generate a Interrupt each 1ms.At begin of INT: -I toggle a PIN, -and, send a SPI data (8 byte or 16..not important)What I noted is a delay of almost 10uS beetwen pin ...
I'm trying to update the duty cycle of 3 channels of timer 1 simultaneously with just one DMA event.
Hi,I have scoured the web for a solution to this problem, but I cannot find one, typically the replies are the same, but the solution is never found. I have tried every other solution you will find.I was playing around with the cube mx trying to solv...
