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...

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...

I am using stm32 nucleo-L552ZE-Q. The ADC reading with the DMA doesn't work

I am trying to read an analog signal from a sensor with the ADC of my board. I set the pins correctly I think ( DMA_continuous_requests enable, circular mode, etc. ) and I started the DMA with HAL_ADC_Start_DMA outside the while(1) loop and I put a b...

How to store user input in a variable?

I am working with a Nucleo-L476RG and I am using PuTTY as an interface using UART. I am trying to use PuTTY to read a numerical value from the user and then store that entered value in a variable. Below is how I am initializing UART to receive user ...
