New possibilities for the ultra-low power segment!

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...

STM32H7R/S lines: 1st STM32 with bootflash and on-the-fly encryption

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...

HAL_UART_Transmit_DMA

i'veA question related to transmission using DMA. i'm facing a strange situation.it works perfectly when i use "HAL_UART_Transmit_DMA(&huart1, TxBuf, 5);" in the main program.However in my project i've crated a separate file for my application progra...

ST.com website does not allow new registrations

I have been trying to register an account on st.com for two weeks now, with no success.When clicking on the register button, on the page where you fill in your details, nothing happens.In the javascript console in my browser it gives an error: Uncaug...

How to improve the speed of SPI-DMA operation. Basically I want to avoid waiting in while() after transfer of data.

I have a working code for SPI with DMA support added. Now I want to improve the speed of operation.I am using an STM32F427 controller.#define SPIx_Mode SPI_MODE_MASTER #define SPIx_Direction SPI_DIRECTION_1LINE #define SPIx_Dat...

Where can I find the STM32100B-EVAL demonstration firmware?

Posted on October 01, 2011 at 01:15I found AN3126, which refers to ''STM32100B-EVAL demonstration firmware'', saying I ''can download this firmware and the associated user manual (UM0891) from the STMicroelectronics website www.st.com.'' I found UM...

Resolved! Is there an image file to program the STM32100B-EVAL board (MB871 Rev.B)? I have the board but a blank display is all that happens on power-up. Also, is there any User Manual and other Documentation for this old but attractive board. Thanks in advance.

Is ST still making the STM32H7 series parts? Every time I look for availability the lead times keep going out further and further. Those parts that had short lead times suddenly changed to more than a year out with no explanation.

Can I use the SAI block to trigger ADC on STM32H7?

I am using the STM32H743 on STM32H743I-EVAL board.Is it possible to synchronize ADC acquisitions with the SAI block? The goal here is to acquire audio ADC samples using DMA, block process, and transmit out to a DAC over SAI using DMA. The STM32 is th...

Assymetric Timer output [STM32G031]

Hi,I am playing around with Timers on Nucleo-G031 at 64MHz clocked from HSI and PLL.I use TIM1 with AutoReload of 6 and Capture/Compare Value of 3 to create an 9.17MHz 50% duty-cycle signal.The signals turns out to have 46.4ns high-pulse and 62.8ns l...

Resolved! Can't get max frequency out of STM32H7

Hi everyone,I am having a hard time trying to get the max clock frequency out of the STM32H753ZIT6U.This is the revision V model and is capable of hitting 480MHz unlike its Y revision. This is my code to get to 480MHz:LL_PWR_ConfigSupply(LL_PWR_LDO_S...

Resolved! Hi, I am losing data when sending longer as 8 Bytes messages over HAL_UART_Transmit_IT. Only when adding a Hal_delay of 40 ms the correct data will appear. The buffer is and TX/RX are not used in the meantime.

I'm using FDCAN and UART (9bits) on a custom board STM32G0B1RBT6. The longer messages from FDCAN are split up in 8 bytes max and combined on the board, which works. I can see the correct array of data until the transmit function, but on the bus not a...
