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'm trying to do a periodic ADC capture on 2 channels, triggered by TIM5. ADC should output to memory via DMA, with a DMA interrupt upon each completion to read the data from each scan.So far, the DMA interrupts aren't hitting, and the ADC doesn't ev...

I am trying to receive messages in DMA mode, on a STM32L432KCU. The pins PA2 and PA3 are configured as DMA pins. The baudrate is 115200 and the global interrupt for USART2 is turned on. In the main function, I have the initialization of the periphera...
In STM32U575/585 RM0456 Rev 2 from September 2021, I see the following:"11.4.7 LSE clock...External source (LSE bypass)In this mode, an external clock source must be provided. It can have a frequency of up to 1 MHz."However, in STM32U585xx DS13086 R...
Hi.I init global array DMABuf[33] = {0}; According C++ standard it must be filled zeros.DMABuf placed into SRAM1(2) i.e. SRAM D2. Immediately after reset the buffer contain zeros. After initialisation DMA, buffer and all SRAM D2 contain random number...
Hello,for a switched capacitor ADC with differential inputs, I would expect no limits on common mode voltage as long as input voltage is in the GND/VDDA range. However STM32 ADCs only allow a small range of common mode voltage around (Vref- VDDa) /2....
STM32L412KBUx on NUCLEO-L412KB, STM32CubeIDE, Version: 1.8.0.I'm trying to use TIM1 to measure frequency of an external input signal connected to PA8. I'm confused by the choices in CubeIDE. In Pinout & Configuration, TIM1, Channel 1, I selected Inpu...
I have set up an SPI interface between Nucleo-STM32L476RG and TI CC1200. Working in STMCube IDE and mostly using MX to generate drivers for SPI2. The SPI interface works and I am able to send comands and receive regster values to/from CC1200 however,...
I started a new project using an STM32G473CB in the QFN48 package. I've used this and other G4 chips for many other projects and never encountered this issue. This issue occurs with all 3 flash size variants (CB, CC, and CE).I've replicated this issu...
I create a custom board to use PT4115 to control LED. This PT4115 can be control with PWM or external DC on DIM pin. According to spec, the DIM range is 0.3-2.5V.I tested the board by I short the DIM pin to GND and the LED turn off.So it show the boa...
