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,I recently bought Nucleo F334R8 which is an ARM 32-bit Cortex M4 microcontroller with both ST and Arduino connectors.I would like to ask about the accuracy of any data from sensor interfacing.The microcontroller is said to have 32 bit accuracy ...
I need to use STM32G070 Timer 17 output compare channel as one pulse PWM1 mode to produce delay and pulse duration at GPIO output pin (this is working!) AND also an interrupt/event at the end when ARR value has been reached (this is not working). Is ...
E.g. RM0351 Rev 6 tells for UART/CR2 / ADDR:" This bit field can only be written when reception is disabled (RE = 0) or the USART is disabled (UE=0)"However it seems thaT RE = 0 is not sufficient. Only with UE = 0, a new address may be written.(gdb...
Hi Colleagues,I am just trying STM32F103 using Encoder in TIM3. I am able to count the pulses and direction ; prima facie it looks fine.I am using the STM32 CubeIDE for configuring the parameters. I have a few questions though :1) I need to compute t...
I am learning bare-metal programming on STM32F411RE (Nucleo board). I am trying to implement a SPI driver.Reference manualEven though I have set the Data Frame Format to 8-bit, My SCK consists of 16 clock cycles. Sending 8 bit data on this has weird ...
MCU is STM32H743ZI. When QUADSPI working in AutoPolling mode,Setting the ABORT bit in the QUADSPI_CR, Why SR.BUSY bit stall high? BUSY don't goes low forever!But according to referrence manual,"In automatic-polling mode, BUSY goes low only after the ...
What kind of reason would the DR register read the same on subsequent calls in release build?If I don't add __NOP()'s in there, the registers read the same and the FIFO doesn't get emptied.Micro is STM32F769NIstatic uint32_t drvInit(void) { uint32...

I’m designing a motor control PCB with two STM32G432RBs (situated close to each other on the PCB) driving a boatload of H-Bridges, encoders, servos, and other I/O. I’m planning a dedicated (synchronous) USART connection between the two STM32G4s to ke...
