Hi I am trying to get a high ADC sample rate "above 10MHz" with the STM32G4 family, I am playing with NucleoG474RE at the moment. I can see there is an example of Triple Multimode Interleaved for CubeF4 :STM32CubeF4/Projects/STM324x9I_EVAL/Examples/A...
Good morning. I want to use my Nucleo to light up the LED of my stm32h747. For this, I first programmed a GPIO output for my nucleo board. I connected a wire and measured 3.4 volts and 120 mA with a multimeter. then, I decided to toggle the wire to p...
I would like to enable write protection via an option byte.However, HAL_FLASH_OB_Launch() hangs, and even if the CPU is reset afterwards, the option byte is not rewritten.This issue occurs with both combinations: my board + J-Link or Nucleo + ST-Link...
Hi,I run the NUCLEO-F303RE eval board. I separated the ST-Link part from the target processor part and connected GND/TCK/TMS/NRST/SWO by wires. I populated the 8MHz xtal with Rs and Cs on the target part. This works fine.I copied the circuitry for th...
Hello,I have an Olimex board with an STM32F107 cpu on it.It start in the bootloader and I can upload firmware to it.For this I use CubeIDE and CubeProgrammer.I need to give USB support to my application so that to communicate with a PC.In CubeIDE, I ...
I'm trying to set the polynomial for the CRC block and having some difficulty. I want to set the CRC block to compute a CRC-32K (Reversed Koopman) over my data.Here are the detailsCRC-32K (reversed Koopman polynomial) - 0xEB31D82EInput data - 0x31, 0...
HiMy name is Jonah and I’m working on STM32L031K4U6 .My device needs to go to standby, wake up via PA2(WKUP3) or RTC wakeupI follow Doc RM0377 page 869 (to update PRER) , page 870(to update CR)If I write : RTC->CR =0x00000404U; ( WUTE=1 b...
Hello, i try to configure a STM32H7S7L8H6H in CubeMX and it seems that, when Ethernet RMII is configured, SDMMC2 is unusable because there are some pins like PC1 which can't be remapped. Can this be true?This chip is designed for external memories an...
Hi, I am having a problem with a unexpected restart.The first time I use the I²C bus by invoking HAL_I2C_Master_Transmit, the MCU restarts after reaching this line:line 7276 of stm32g4xx_hal_i2c.c/* update CR2 register */MODIFY_REG(hi2c->Instance->CR...
Hello STM Comunity, I am making this post because I have reviewed many reference schematics for the use of the STM32F103C8T6, and in most of them, I see that they use 20pF load capacitors for the LSE circuit.The datasheet literally states that the va...
