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...
In RM0351 Reference manual Figure 420. USART block diagram, the positions of shift registers and data registers (of both Transmit and Receive) are wrong; their positions should be swapped.
Hi Guys.I want to send data to UART using DMA. Every 3transfers I want to generate another DMA request to transfer data from the timer CNT register to memory. The documention of the DMAMUX is basically impossible to understand. They have lines and si...
Hello,I have 10 devices STM32L496VG in Dual-Bank-Boot mode with the identical firmware in BANK1 and BANK2.In 5 devices is booting from BANK1 enabled (BFB reset) and in the other 5 devices is booting from BANK2 enabled (BFB set).I would expect the sam...
Hi All, I just got NUCLEO-H503RB for I3C. And tried to download the image that I built. (just followed the link's instruction)https://wiki.st.com/stm32mcu/wiki/Getting_started_with_I3C and I just realized it needs ST-link to run and debug my codes. B...
Hi ST!I am writing to ask if any ST MCU's will be released with 2x independent FMAC units?At the moment, doing stereo audio processing with a single FMAC is problematic (and ST MCU's ONLY have a single FMAC unit), especially being unable to load the ...
Hello,i have custom made board assembled by STM32F767BIT6 and external SDRAM IS42S16400 for video buffers.The MCU runs at maximum speed 216MHz. LTDC seems to work fine bud when i use dual layer, the second layer seems that reading from external SDRAM...
I am running USB in Mass Storage host mode. On connecting the device, USB FLASH stick, it takes around 20 seconds to change the Appli_Sate from APPLICATION_START to APPLICATION_READY in usb_host.c file. It is normal ? Can the time be reduced ? Than...
Hi I m using SPI to transmit and receive data from a sensor, the sensor return 3 bytes of data, SensorRXBuff[0], SensorRXBuff[1], and SensorRXBuff[2], i m gona use these 3 byte for indivual computation, i enclosed the function below, could anyone ad...
Hello folks,I've been having a weird issue and haven't found anyone else with the same problem, so I figured I'd post here.I have a project for the STM32H735 BLANK. The PCB has an 25 MHz external oscillator (ABM8W-25.0000MHZ-8-D1X-T3) used as the HSE...
I have a custom designed board using a single WS2812B RGB LED.I use the DMA to control, just as "all" examples and drivers use it.Fairly simple, and it works as a charm.99% of the time...Symptom:Once in while, it starts to show a wrong color.Fx. if I...
