STM32H723 SPI clock issue
In my project I've set the SPI clock to 125MHz; with a SPI prescaler value=4 all works good, when I set it to 2 the SPI stops working and ther is no clock signal.Any helps ? Thank youCarloV

STM3H743VIT6 and LAN8742A Not functioning on 7/10 PCBAs
I have a PCBA design that uses a Molex Picoblade connector instead of RJ45 due to enclosure height restrictions. The PHY IC is a LAN8742A and the MCU is STM32H743VIT6, the ethernet is also POE.I have spliced, a ethernet and 8pin Picoblade connecto...
STM32G4: Wrong description of HRTIM_ADCxR registers in RM0440 Rev 9
If I am correct, the descriptions of - HRTIM_ADC2R - Bit 22 - HRTIM_ADC3R - Bit 19 - Bit 13 - HRTIM_ADC3R - Bit 22 - Bit 13 - Bit 10 - Bit 5 - Bit 4 - Bit 0are not correct in the RM.They all describe trigger event generation but th...
Supported PSRAM and Flash for the STM32N6xx
Hey guys, I'm looking for some suitable HexaSPI PSRAM and also the OctoSPI Flash for the STM32N645 board I am just building.. I cant find the parts used on the DK so do you have a list of supported memories? I need 256Mb PSRAM and will start with a 1...
STM32H7R3 PSSI RDY/DE bug
Hello,I dug deeper into PSSI behavior, and and I observed unwanted behavior. From my point of view it is a bug.PSSI is configured as:OUTEN = 1 (transmit mode)CKPOL = 0 (outputs driven on rising edge, inputs sampled on falling edge)RDYPOL = 0 (0 at in...
Calibrating the STM32's real-time clock (RTC)
I have an STM32L011F4P6 with an RTC. It is running at 3.3V and 16 MHz off the internal HSI RC clock. The RTC is driven by a +/-20ppm 32.768 KHz crystal. It is running at room temperature (23-25C). After calibration, I am losing several seconds pe...
USART + DMA and RTO (receive timeout) together ?
Can i use UART + DMA ( normal ) + RTO ? I try to add RTO but when activate RTOE bit the DMA buffer stops fills .I take interrupt with active RTOF , stop DMA , but nothing in buffer !? I use stm32H7 with hardware implemented RTO. Can some one to give...
Resolved! Power consumption of STM32H5 MCU for VIO Pins
Dear ST Team,I am using an STM32H5 series microcontroller in my design and I am trying to understand the overall power consumption contributed by different MCU interfaces.So far, I have identified the following:The typical maximum current on VDD, in ...
DFU issue after flashing STM32G0B0VET
Hey, I am using the STM32G0B0VET (16MHz HSE) with a virtual com port over USB. The virtual com port is working fine but as a backup I would love to be able to let the user reflash the device. I was thinking of using the DFU for this since then the u...
STM32F733 Internal Temperature Sensor: Large deviation (>10°C) vs. Ambient Temp
Hi everyone,I am currently trying to measure the CPU temperature using the internal temperature sensor of an STM32F733.I am testing the device inside a climate chamber (oven) to verify the readings. I am fully aware that the datasheet states the sens...
