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...
Posted on December 04, 2015 at 19:22Hi, In a goal of a personal project, i am trying to profile energy consumption of an ARM MCU board, so i take the ''stm32F407 discovery kit'' as an experiment example.In my power measurement experiment i always ge...
Posted on December 04, 2015 at 16:46I am working on a Nucleo152RE using EmBitz. The code generates a PWM signal (200Hz 50% duty-cycle) on PB8 (TIM4 channel 3) (It works, I tested with an oscilloscope), then gives this signal as input to PC6 (TIM3 ch...
Posted on December 04, 2015 at 15:06Hello,I am working on in-application programming of STM32F427, 1MB flash. I have set the DB1M bit in the flash option control register, so the flash memory is organized as two banks of 512 Kbytes each. I am trying...
Posted on December 05, 2015 at 09:10Hi I'm trying to get the RTC work on STM32F746G-DISCO Board. The problem I'm facing is the calendar counter except SubSeconds stop counting after calling the function HAL_RTC_GetTime() since the first time. I've t...
Posted on December 01, 2015 at 10:50We want to migrates our platform from STR710 to Stm32F4x ,Can Usart of STM32F4X(Smartcard mode ) connectes the Smartcard Pin without the ST8024 ? #smartcard
Posted on December 04, 2015 at 09:47Today I've updated CubeMX to 4.11.0 version and library for L0 series to 1.3.0 version. I wrote a Project include USB Custom HID, ADC , DAC ... everything work fine except USB Custom HID. It work but speed is too ...
Posted on December 03, 2015 at 10:19Hello. I use ltdc interface to communicate with 800*480 tft screen. I need to rotate the image by -90 degress. Is it possible to do it by hardware? Software do it too slow.
Posted on December 04, 2015 at 00:15Hi, I'm new to using both STM32Cube and the FreeRTOS it provides support for, and I am trying to follow the tutorials and the FreeRTOS manuals online to create 2 separate tasks to manage the two I2C busses on our...
Posted on December 04, 2015 at 07:07for the SAI example in cubeL4, it looks like running 22050 sample rate, and the input clock is 11.294M. I measure the frame len is about 45us which is 1/22050. Now I develop an audio app runs 44100, I have checke...
Posted on December 04, 2015 at 15:33Hi. I have to do some calculation, where I need to be precise and have to use sine function. I do that calculation only once and speed of execution here is not so critical. So I dccided to use floats (before I had...
