Hi,I'm using a STM32L031. When I'm entering the low power sleep mode und an interrupt occurs i'm getting a hard fault. The programm counter from the stack frame has ether the value 0x00000000 or is pointing at the __ISB after the __WFI - depending on...
Hi I'm using STM32F411RET6 MCU. I tried to connect using the programmer to download the firmware, but there was an error as shown below, and the data cannot be read. 13:18:34 : UR connection mode is defined with the HWrst reset mode13:18:34 : ST-LINK...
Hello. I am looking for an example or help, how i can receive data from stm32 at 100kHz with Python via com port ? ADC samples at around 100Khz and streams the data i am not sure how to receive it correctly at this high speed. Thanks a lot
Dear all,I am facing very poor performance with the STM32N657.I have some benchmarks that manipulate arrays of data in different ways.I ran these benchmarks onNucleo_H753 @ 480 MHz, with caches ONNucleo_N657 @ 600 MHz, with caches ONFor the STM32N657...
I have NUCLEO - N657X0-Q board and it has an external flash.. Whenever i upload a code it gets uploaded and runs but when i restart it, it runs on the default code it came in. Can anyone guide me how can i upload the code to external flash. I have tr...
Hi, I´m trying to implement ESD protection to a custom board, I found recommendations for this part number (USBLC6-2SC6), which clamping voltage is as follows Look at VCL Clamping Voltage there are 12V and 17 V Then the USB pins of my MCU accept a ...
Split from this thread. i've had the same issue. Set the internal pull-up on Rx pin and pull-down on Tx pin.
Hi everyone! I designed the board shown in the attached picture. It’s built around an STM32H745 microcontroller, along with crystal oscillators, a DAC, an EEPROM, and an NE555 that generates a reset signal when a button is pressed long enough. Afte...
Hello,I am designing a board with a STM32F446 connected to an IS42S16160H SDRAM through the FMC interface.Could you please provide ST’s official recommendations regarding the use of series resistors on FMC lines?Typical values (22–33 Ω)?Any ST guidel...
