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...
Went through examples of Nucleo -L073RZ eval board for PWM outputIt generates four PWM waves using Timer 2 channel 1 ,channel2 ,channel 3,channel 4at 50%,25%,12.5.37.5% duty cycle . So the pwm duty cycle is fixed.but i have a fan pwm connected to T...

I am trying to use asynchronous USART on stm32L4R5ZI nucleo board for sending and receiving data. Following is related part of code.while (1) { HAL_GPIO_TogglePin(LD2_GPIO_Port,LD2_Pin); //Toggle LED HAL_Delay(1000); //Delay 1 Seconds for(...
Need to verify a STM32 firmware for DSP use. Message me for more details.
I need two quadrature encoder input pairs. The standard ST selection matrix only includes the number of 16-bit and 32-bit timers.
Hi,I have to configure a STM32F373 as a LIN Master. The problem is that the function USART_SendBreak is not available.The reference manual says that I have to set the SBKRQ bit to send the break frame, but this bit is only available for a break reque...
I use the STM32L4R9I-EVAL Board and try to configure the ospi on nor-flash for readonly in memory mapped mode. there is an example projekt in Hal-Lib L4 V1.14.0. If i skip the erase and write steps, it read out wrong values (with out hal error)!Do an...
MCU: STM32F777Cube: 4.25.0FW: v1.11.0I'm seeing cases where the F7's SDMMC isn't setting any of the required Status Register bits as the result ofan R1 response to a READ_SINGLE_BLOCK command after having previously handled up to tens of thousands of...
Hi AllCan anyone suggest the example code for Spi interfacing between STM32L151QD and External flash memory.,Through my STM32L151QD I want to read and write from External flash memory , The both STM32 and Flash memory is connected with SPI interface
I saw the web https://community.st.com/s/article/FAQ-DMA-is-not-working-on-STM32H7-devices,and I change the ram address.uart can transmit with DMA but can`t receive.and the spi can`t transmit with dma.
