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 April 30, 2018 at 23:15 Hi, I have a project where I need to communicate with CP2110 via USB (medical device having this interface). I am prototyping the application on STM32F746G-DISCO. I have started by running the Application exam...
target CPU: STM32F427IGI set up STM32F427IG as master receiver via DMA. I wait on "DMA_GetFlagStatus(I2Cx_DMA_STREAM_RX, I2Cx_RX_DMA_TCFLAG" to figure out if I received what was sent.After running for 20 minutes or so, I2Cx_RX_DMA_TCFLAG flag does n...
Hi I want to use the high resolution timer for a 10 bit resolution PWM output. Even the ioc file tells me that it turns on 480 MHz but it doesn't.I tested with a digital storage Oscilloscope the output of the PWMI used the basic configuration so i ha...
Hi, I am new on mcus and STM32 board. Now I am stuck on a test project. I have a STM32F56ZG nucleo board and want to sample values from 4 ADC inputs; process them and then output the result on DAC channel 1. I am using DMA triggered by timer 6. The...
Hi,Master:Platform: STM32F301K8UCPU clock frequency：72MAs shown in the figure, the original analog video signal (PA7 pin) is compared with DAC1_CH1 through a comparator, and a pulse sequence with a slightly changed duty cycle and period is output....

Hello,I've designed a board based on an STM32F091CBU.I needed CAN bus support, one SPI and one I2C and a timer interrupt.When I tested my program, it hanged during the initialization of the IMU (an LSM6DSM) due to HAL_delays I ordinary set between SP...
Hi,1.Wanted to know does the execution time reduces(speed increases). If text segment is brought to SRAM from flash at start up and executed in STM32H743 MCU2.Wanted to know are there any optimization techniques to improve speed like using I cache ...
Hi guys,My code is acting strange, when it seems to intermittently get stuck during the HAL_Init() function at the start of the code. The issue never throws an error ( but the debugger constantly pauses at HAL_TIM_PeriodElapsedCallback() despite ther...
