Dear Forum,I'm using a STM32F401 and implemented the I2C as Target transmitter (Slave) answering a I2C question. I'm programming the I2C CR2 (FREQ Bits) Register as follows with correct speed (42 MHz)I2C1->CR2 = ((DRV_RCC_GetPCLK1Freq() / 1000000u) &...
Hello, we are seeing a weird symptom in our application in which all LTDC registers are reading back the same seemingly random number. This is during a debugging session via system viewer (we are using Keil 5.40 and compiler 5), OR when reading and ...
Hello!I am using a 32.768 kHz TCXO (TG-3541CE) as the LSE to count the RTC.The MCU is an STM32L452RE.At room temperature, the RTC operates correctly, but at high temperatures (around 50 °C), the RTC stops.Strangely, once it has stopped, touching the ...
Hello everyone, I have a NUCLEO-H755ZIQ board and I am trying to use the HRTIM to output a 50Hz pwm signal. I hook the output to an oscilloscope and I see that the pulse has a period of 19.2ms instead of 20ms, meaning that while I have configured the...
Hi,we are using the internal SMPS for core voltage generation.VDD, VBAT and VDD18AON are on 1.8V. My question is if I can also power up the other 1.8V lines (VDDSMPS, VDDA18USB, VDDA18CSI, VDDCSI,VDDA18ADC and VREF+) simulteanously with VDD, VBAT and...
During the initialization of STM32 UHS-I, it has an IO output of 3.3V. After initialization, it outputs at 1.8V. However, I noticed that the external voltage switch transceiver is powered at 1.8V on the host side. I'm afraid it might burn out the ext...
Hello ST Community,I’m working with the STM32 Nucleo-N657 board and need a way to execute my application after flashing to external memory without manually toggling the BOOT1 jumper on the board.What I’m Doing Now:BOOT1 jumper is set to HIGH for deve...

Hello Team,We are developing custom board using STM32N657X0H3Q MCU. I could not find information regarding GPIO status in datasheet during boot mode, sleep mode, stop mode and standby mode. It will be helpful for us if you can share information with ...
Hello dear community!I've migrated from F7 to H7, everything fine so far.To save CPU time I don't want to use HAL for sending two SPI bytes.My F7 transmit SPI code was very simple and perfectly working :SPI6->DR = byte_0; SPI6->DR = byte_1;But on the...
