Hi ST team,I'm implementing DShot protocol with Timer + DMA. I use 4 PWM channels to generate control signals for ESC. Timer and DMA's parameters are same for all PWM channel. But PA3 (TIM2_CH4) does not work the same as other PWM channels. It only t...
Hi Everybody! I confronts a very interesting problem at my project. Details above:Hardware: NUCLEOG071RBAttached the IOC configuration. Control the SPI CS pin by software. I got small 4-8us signal spikes all GPIO, SPI, I2S pins. SPI and I2S powered ...
Hi, I want to go to sleep/stop mode with STM32 and wake on interrupt. After last interrupt it should wait for 10sec and go back to sleep. But I see an edge case where interrupt could occur just before going to sleep/stop mode.How do I handle interrup...
I have a custom board with an STM32G473 running at 170MHz. I have the QSPI peripheral running correctly in indirect mode when the pre-scaler has a value of 5 (so ~23MHz) but when I decrease the pre-scaler any further all HAL_QSPI_Receive calls end up...
I have a question regarding voltage level I/O compatibility for STM32 MCUs. The sensors providing analog output within a 0–5V range, while those with digital output at either 0V or 12V. Although some GPIO pins on the MCU are 5V tolerant, they are sca...
I conducted some test in case the option bytes in the STM32L474 (Nucleo 64 board) are set incorrectly for my application. Note HAL is not used (it's a strict bare metal application since this is a home experiment to reduce power consumption to the ba...

We have tested the STL package in 2 scenarios for Flash test on STM32L452: CASE 1: Linker settings:FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 512K Pre-Post build settings:0x08000000 0x08080000 0x400 STL user template settings:/* FLASH configur...
As the subject states I am trying to get Ethernet work on the VET6 Microcontroller. I have tried to configure my microcontroller like the Ethernet example project provided on Github for the STM32H723GT. I have tried the exact code on the H723GT Nucle...
Hi,I have made my own board using STM32F103RBT. I am trying to run a demo code on it using ST Link V2. When I first connected the board I was able to connect to the controller after downloading ST Link Server 2.1.1 and dump a code, but when I am tr...
