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...
I am trying to create a voltage divider to read a battery voltage of 2.5 - 3.8 V using a STM32L082KZ with a Vref of 1.8V. While calculating the required division to measure the range i wanted to include the influence the ADC measurement/loading has o...
The datasheet says that power must be supplied on this pin if USB is to be used. It must also be the last power supply to be energized and the first to be removed.If my design does *not* use USB. Can I tie this pin to VSS and call it a day?I want to ...
Hello All,I have implemented a simple Web server using https://github.com/STMicroelectronics/STM32CubeF7/tree/master/Projects/STM32756G_EVAL/Applications/LwIP/LwIP_HTTP_Server_Socket_RTOS example. The Get method works fine but as soon as I use the PO...
I have an STM32-L4P5DK connected to an external ADC, with SPI2 configured to read ADC samples on every falling edge of the DRDY signal. The DMA1 configuration is as follows:DMA1 CHANNEL1: DMA_GENERATOR0DMA1 CHANNEL2: SPI2_TXDMA1 CHANNEL3: SPI2_RXThe...
Hi Everyone, I have a project utilizing a STM32G030F6P6 with a 32.768kHz crystal and the LSE to source the RTC clock. It is exhibiting 2% clock error (which is huge!) over a 10 minute period despite using a 20ppm crystal. I am measuring this error by...
I need to generate a pulse which is activated high immediately by rising/falling input signal around 100Hz with varied width. I have tried One Pulse Mode and Gated Mode on STM32f334R8T6 so far but none of them were successful. Even I tried on HRTIM,...
Hii, I am trying to interface ADC module cs5532 using SPI communication with STM32H563ZIT6 on NucleoH563zi board. I have also completed pin configuration on .ioc file and successfully generated a code. But SPI communication is not initializing. I h...
Hi, I'm working on ADC1, on a STM32U5 (on a Nucleo board). In reference manual (RM0456) § 33.4.13 "Channel-wise programmable sampling time" we can read how to compute the total conversion time Tconv. The example is given for SMP = 5 ADC clock, at 55...
I'm using stm32h5-nucleo144-board to develop USB (HID or CDC_ACM) application, I start with STM32Cube_FW_H5_V1.3.0 code by directory STM32Cube_FW_H5_V1.3.0\Projects\NUCLEO-H563ZI\Applications\USBX\Ux_Device_HID_Standalone.firstly, when I download th...
