Trigger SPI using Timer
I'm using STM32H723ZG I want to know if a Timer's update event can trigger SPI transfer without any software interrupts.This is the problem

STM32F303 UART TX with DMA stops after two bytes under high traffic
Hello,I am experiencing an interesting problem on the STM32F303VET:UART1 is used to receive and transmit messages (460800 Baud), DMA1 Channel 4 is used for memory to UART TX buffer transfer, DMA1 Channel 5 for UART RX buffer to memory transfer.Under ...
Resolved! HSE Bypass mode - Possible use of OSC_OUT as GPIO
Hi I am looking into using STM32F446RCTx for my design, which includes 2 x USB FS 2.0 (1 x Host + 1 x Device). Hence need to provide an external HSE. I want to use an Oscillator, meaning I setup the HSE as "Bypass Clock Source" .With this setup I pla...

Resolved! STM32U073 VREFINT wrong calibration value in flash?
Hello community,I am running in an issue with the VREFINT calibration value of the ADC.For calculation I use the __LL_ADC_CALC_VREFANALOG_VOLTAGE function from the stm32u0xx_ll_adc.h file and I'm getting wrong values.The Chip is powered with 3.3V and...
Resolved! STM32 with Cortex-M85
Could it be time for ST to reveal such an MCU at the summit in a few weeks? Or maybe a Cortex-M55 that actually have integrated flash or MRAM or similar? (STM32N6 is interesting, but I would like to see flash/MRAM/something else integrated...
Resolved! STM32CubeMX H7S3 RCC_CCIPR1 incorrect initalization code generation
When using PLL3Q as input with a frequency of 32MHz for USBPHY I have a RCC_CCIPR1 register initialized at value 0x2a00 when entreing USB_CoreReset function that is not correct (should be 0x2b00).
Resolved! STM32H573V UCPD CC2 and PC9 interference
HI,I am working on a board using STM32H573V and have a working solution with UCPD detecting an inserted memory stick and running the MSC class. In an other part of the software I am using PC9 as an GPIO push-pull, low speed output and as soon as I se...
STM32F4: I2S1 DMA receives data from I2S2 when both interfaces run simultaneously
I'm working with an STM32F411 and trying to run two I2S master-receiver interfaces (I2S1 and I2S2) at the same time, each receiving data from a pair of PDM microphones using DMA circular transfers.However, I found a very strange and extremely hard-to...
Resolved! Configuration issue with Combined PWM mode on STM32F303RE
Hello everyone, I’m new to STM32 and I’m currently stuck with using timers.I’m working with an STM32F303RE, and the goal of my project is to generate 6 signals at 100 kHz (high time between 100 and 500 ns), each phase-shifted by 60°. These signals wi...
