Hello!
I have a PCB that uses STM32U575 MCU and it has 3 sensors shown in the image connected to it through I2C bus. Using internal ADC of the MCU I want to also read the analog data that is coming from the bus. Is there a way to do it? Maybe there is a example or a reference project which I...
Hello everyone! I have a task to choose ADC that will have at least 10 MSPS sampling rate and will be able to connect to STM32U575 directly. I very new with this topic, was searching through and found several ones that look like they might work.
Wanted to ask if someone can provide a feedback...
Hi dear all,
I'm looking for dual ethernet examples to implement with my stm32mp157d MPU , but I couldn't find anything on the internet.
I've seen that there is no STM32 with dual ethernet interface but i want to add dual ethernet and fiber ports to my stm32mp157d but i can not find any...
Hello,
I have a question about STM32F407.
I was wondering how to software trigger (not external trigger) a "one pulse" timer, using HAL library?
Thanks for the help.
I want to use the thread function and the system throws an error

hi
I'm using stm32 F103RBT8 i want to set my watchdog time out to 15 seconds. in IWDG i have no problem to configure 15 sec time out but the problem is i cant turn off IWDG once i turned it on and in my code i can't reset each time before stop mode.
in WWDG it's clock source stops in stop mode...
HI,
I have written the below code for my STM32F446RE Nucleo board. All I am trying to do is turn on Pin PA3, Pin PA2 and onboard LED Pin PA5. The code compiled and flashed successfully. But no success in turning on LED pins except onboard LED Pin PA5. I don't know why Pin PA3 and Pin PA2 is...
hi
I'm using stm32 by keil5 compiler and This is my printf function

To fast prototype interconnection PCBs using direct ink on copper, with a cost of 0$ using all needed material from my surplus collection, I made a simple pen plotter using some old printers part, a STM bluepill board and few electronic components. The x axis is a carriage of a dot matrix...
Hi everyone,
Could someone please let me know if ST MC Workbench implements SVPWM ? I have been looking at all features in the workbench but I haven't found any settings which allow tuning of the PWM algorithm. Thanks in advance.
I'm trying to make an IoT based project that works on Real-Time data accumulation, for that, I need to know whether the STMF0 series controller are efficient or not.
I have a 4MB NOR Flash. i want to show this memory as Mass storage on a PC when connected as a USB device.
I have some confusions regarding the need of Filesystems on a NOR flash. I have a reference device (a data logger which mounts its NOR FLASH as USB storage when connected to PC. It uses...
Connecting a 512K*16bit SRAM (IS62WV51216BLL-55TLI) to a 144-Pin package STM32 microcontroller, using the FSMC bus
In some projects, such as using a graphical LCD by the StemWin (EmWin) library, the embedded STM32’s SRAM capacity might not be sufficient. For the 100-pin and 144-pin STM32...
Hi,
I designed a kind of SWD & JTAG Isolater for Jlink & STLINK, for online debugging.
This may keep person and PC USB port from PCB board burning.
Can be used in Motor Control, Digital Power and some high-voltage applications.
IDE: Keil, IAR, Jflash, STM32 ST-LINK Utility；

Hi,
I'm using ST7565R lcd with STM32F3 board but failed to initialize the lcd properly, I added the 1uf capacitors as per datasheet . I have observed 1.358V at the V0 pin and 1.359V at V1,V2,V3,V4 pins . And I have attached my code here, please help me someone to resolve my problem.
Hello
I am sooo excited!! I have recently purchased my first ARM board. It is the STM32F4 discovery kit with the STM32F407 chip.
I have downloaded Keil for development purposes. I wanted to know if there is any simulator for this (Proteus like). I have Proteus 8.0 in my university but I...
Hello everybody and thanks always.
This time I would like to ask if someone has tried mbed to program a STM32 Nucleo board.
I have one (STM32F091RC) and I have used mbed to program a couple of examples (LED switching, using a button, etc- basic stuff)
Now the programs seem quite simple...
