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 read some data by ADC using DMA transfer method I configured the ADC attached the code belowI cannot getting the ADC value in all buffer only read the 3rd buffer 1st and second buffer shows grabage value please help me i tried out ...
Hello everybody,Actually I'm working on a temperature sensor. This project works on battery (2 x 1.5 V alkaline).I would like to read the temperature in the room with an external analog sensor.But I don't understand how VrefIN works. Because my Vcc s...
NOTE: I have edited this post after some of the replies, to fix some typos in the code and to use "insert code" instead of "Preformated" to get syntax highlighting. Hello,I would like to understand what is the recommended approach when working with i...
Hi,i want to store information about the bootloader into the FLASH. Since the size will vary during development, i wonder if its possible to put it before the bootloader.If anyone knows about a good tutorial or video, i would be happy. I dont know wh...
In the RM it says the above, but the only information i can find in the chapter that is referenced to is: "force boot from FLASH".Is there a way to define a "unique" entry point, or ist this just wrong in the manual?
Hello, I would like to ask you to know how it is that the PA5 pin in OUTPUT (non-pullup and non-pulldown) delivers a voltage of only 2.6 V instead of 3.3 V like the others? Thanks in advance
Hello Everyone ;we are new to STM32H7 ; we used before stm32f4 in many projects but STM32H7 we still new; so I am sorry to ask simple questions. We have designed our board based on STM32H743BI and SDRAM IS42R32160F-7. After a couple of weeks of tryi...
I downloaded Seeed-Studio LoRaWan-E5-Node, and all works fine till I use the MX component to set up microcontroller configuration (for example, set up LoraWAN or I2C). When I use the MX component and decide to generate code after changes to LoraWAN o...
I am using the Nucleo-H743ZI2 board I wanted to know, how to recover I2C after an error or a locked state which can come due to a glitch or spike on the SDA or SCL line.There is no bit I could find to reset the i2c peripheral in the control register.
Hello All !I am a Mechanical Engineer and totally new to STM32; but the assortment of attractive features on these boards tempted me to get one and start my Project. I need to interface a DAQ for IEPE Sensors. I found found one on AliExpress, similar...
