Hi,Pretty new to STM32 but reasonably comfortable with ESP32, Pico and 40 years of C++. So old enough to expect it to be me.Cannot get blink to work with blue pill 32k using cube ide on ubuntu 23.04 with while (1) { /* USER CODE END WHILE *...
Hello, ST experts It seems that SPI_MOSI on STM32F407 does not show a certain level. So it is vulnerable by other sources. Is that a register bit like SPI_MASTER_KEEP_IO_STATE_ENABLE on STM32U595? So that MOSI can keep a certain level. Best RegardsYa...
I am using a Bluepill Board but it is not functioning as expectedHow do I verify if the chips on my Bluepill Board are genuine or a fake knock off?
Hello STM32 Community, I'm working on an STM32 Nucleo-H503RB board and trying to communicate with a P3T1755 temperature sensor over I3C. According to the P3T1755 datasheet, I need to perform dynamic addressing using the SETDASA CCC. I followed the of...
Hello, I am dealing with difference between real measured frequency and set on my Nucleo H755ZI-Q.the measured real frequency :APB1 76,8 MHzAPB2 76,8 MHzrecalculateddebugging frequencz SWV Core Clock 153,6 MHz I also try printf debuged frequency:HSE ...
Hi All,Is there anyone knows why sample projects do not include a .ioc file ?Are not these project generated with CubeMx ?https://github.com/STMicroelectronics/STM32CubeH7/tree/master/Projects Regards.
Hi everyone I want to program Stm32F103C8t6 via USB and STM32Cube programmer version 2.10.0. I am using "STM32 smart V2." I pulled up the Boot0 pin and disconnected and connected the USB cable to the board (the board's power comes from the USB, so it...
Hello ST Experts, I'm using STM32H747 and I try to run adc calibration at the start of the code, like under lines. HAL_ADCEx_Calibration_Start(&hadc3, ADC_CALIB_OFFSET_LINEARITY, ADC_SINGLE_ENDED); HAL_ADCEx_Calibration_Start(&hadc3, ADC_CALI...
Hi, I designed a board with uC STM32H743 that works with a 480x800 display connected through the LTDC peripheral, I don't quite know how to use the LTDC, I don't have ram for the buffer of the entire display. What I can do is fill the background with...
Hello,This might seem like a silly question but when using the pin names generated by cube IDE for the RMII interface does TXDx connect to TXDx on the PHY or RXDx? On the schematic for the NUCLEO board it seems that the microcontroller pin in named t...
