could you help  for this? I cant find it

Colleagues,Can STM32WL or WB be programmed to function as a baseband chip (with an external mixer) ?I’m looking for ICs which would help me build an HF radio link. My bands of interest are 14 MHz and 28 MHz amateur bands. I like the STM32WL33, because it has a lot of modulation options.Best regards,- Nick

Hello,I am reading the documentation of the STEVAL-PTOOL4A, I have noticed that it is equipped with a TRIG_X  to enable/disable the DC/DC booster. I don't know if I understood well its functionality, but It will mainly turn on/off all the board including the MCU. So each time, we trigger, the MCU will execute from the reset_handler right? But maybe I want to keep the MCU on always, and I want to scan an input and when it is On, it will turn on or off the motor depending on its status. How it could be done by TRIG_X? Or I should use in this case another GPIO and I configure it manually? For example could I use the one of the potentiometer instead? Thank you

What is the default value of the DBANK bit in STM32G4 MCUs. According to the reference manual, flash memory address 0x1FFF 7800 has that option bit, and the ST production value is 0xFFEF F8AA, which would make DBANK default to 1. Does this mean STM32G4 MCUs have DBANK flash enabled by default, and do I need to do anything further to set it to DBANK? Or will it always be enabled out of the factory?

Hi,I am using STM32C071CBT6 chip on my custom board. From datasheet, i could see that there are two versions available - GP and N version. Part number section of datasheet mention about 3 more characters after this part no. to identify if it is N version. Does above description means that there will be letter 'N' at the end of part no. to identify it as N version? And if no letters are present after part no. (i.e. blank ) means it is GP version? My chip on board is as below:Am i right that this is GP version chip and not N version?Thanks,Pradeep

Hii, I want to update the firmware of my STM32H723ZGT6 microcontroller. Here, I want to send firmware file from server to W5500 Wiznet IC then I want that this firmware should load in to the microcontroller flash and it should update the program so can anyone help me with this??

Hello, I am working on the development of a bootloader for the STM32L4S5ZIT6, and I need help to implement a feature where the bootloader is triggered after receiving a user request in the main application (the main app saves a marker in memory). Here is what I am trying to achieve: The main application saves a marker (a magic number) in memory. After jumping to the bootloader, the bootloader checks for the presence of this marker. If the marker is found, the bootloader proceeds to execute (e.g., triggering a firmware update). If the marker is not found, the bootloader jumps back to the main application. My question     Is SRAM backup (BKPSRAM) the best place to store the marker? If so, could anyone provide me with the exact address of BKPSRAM for the STM32L4S5ZIT6 (I couldn't find it in the user manual)? If BKPSRAM isn't suitable, can you propose another solution for saving the marker in a persistent memory region that survives resets? I tried using SRAM to store a marke

Hi there, I'm under mass production with yours STM32L051x8 device. I use the internal EEPROM to keep some data. Note that is not en emulation eeprom on flash, is just 512bytes on internal EEPROM. In addition, I protect my code with ReadOutProtection Level =1. Seems that when I update the version of customer firmware, the EEPROM data is erased. Seems that jumping from Level1 to Level0 produce a mass erase, and in consequence, the EEPROM is erased as well. I would like to know if I'm right. Jumping from Level1 to Level0 produce a mass erase, that produce erase the internal EEPROM as well?   Thanks a lot.

Hi everyone,I want to use my evaluation board's RTC Backup Registers to store some info when not powered. In order to do that i want to connect an CR2032 battery to the Vbat pin of the controller. Below is the part of the schematics of the board showing Vbat connections. Do i need to dismount R52 and connect the battery positive directly to Vbat there and battery negative to GND? Is this operation sufficient for my purpose? Thanks in advance...   

Hardware SetupI am using an ESP32S3 as an I2C master and an STM32G0 as an I2C slave. The STM32G0 is performing two tasks:I2C Slave Communication – Receiving periodic requests (every second) from the ESP32S3 to read dimmer register updates.AC Fan Control via RobotDyn Dimmer – Handling a Zero-Cross Detection (ZCD) interrupt and generating a PWM signal for the TRIAC to achieve smooth dimming. Interrupt DetailsThe ZCD interrupt is triggered every 95 microseconds to ensure precise dimming. Increasing this value results in noticeable flicker.The I2C interrupt occurs every second to update the slave dimmer registers (which also get updated via push button inputs on the dimmer).I have set the timer interrupt (ZCD) with a higher priority than the I2C interrupt to maintain dimming precision.DMA Issue FacedWhenever the STM32G0 processes an I2C interrupt, it misses a ZCD interrupt, causing a visible jerk in the dimming process. This likely happens because the I2C interrupt temporarily bl

在本文的第 32 页，图 38 显示了双电机控制应用的概述。 其中 OPAMP2 通过内部多路复用器连接到 ADC2IN16， 它还输出到外部引脚 PA6，该引脚通过附加线路连接到 ADC1IN1/PA0。 Translation: "On page 32 of this article, Figure 38 shows an overview of a dual motor control application. Where OPAMP2 is connected to ADC2IN16 via an internal multiplexer, it also outputs to external pin PA6, which is connected to ADC1IN1/PA0 via additional lines." 但是，我无法理解这是如何完成的，我也无法在 CUBEMX 中配置它。 第 10 页的图 12 描述了多路复用器的功能， 它不能同时向 ADC 和外部引脚输出信号。 谢谢。 Translation: "However, I cannot understand how this is done, and I cannot configure it in CUBEMX. Figure 12 on page 10 describes the function of the multiplexer, It cannot output a signal to both the ADC and an external pin at the same time. Thank you."

Hi ! We are using an SR5E1E7 with StellarStudio. But we are struggling with CAN filters. How to setup the CAN device so it can accept any CAN-ID? Or better, how mask work for the CAN Filters ? We are using CanOpen and we can't really set every ID we want by hand.Any info is welcome, whether from StellarStudio configuration or C code using `can_set_filter`.  Currently we only made it to work with one ID: Could you give an example on how to setup filters for:- Allowing all ID's - Allowing all ID's from a mask   Thanks in advance !

Hi I'm doing a new design using an STM32H563 and would like to use LPTIM2 to measure elapsed time. Ideally I'd like its clock source to be PLL2P, which means RCC->CCIPR2.LPTIM2SEL = 0b001 according to RM0481 page 545. However, if I select this clock source then LPTIM2 appears not to be clocked at all. In my code snippet below, ARROK is never set and the code hangs waiting for it. If I set LPTIM2SEL = 0b000 (rcc_pclk1) then it works fine, and so does 0b101 (per_ck). If I then break into the code using a debugger, and manually set LPTIM2SEL back to 0b001, then LPTIM2 stops counting. I've confirmed that PLL2P is definitely enabled and running at the expected frequency, which in this case happens to be 4 MHz. I have MCO2 set to output PLL2P on a physical pin and I can see it on my scope, so PLL2P is definitely OK. It just appears not to actually connect to LPTIM2 through its kernel clock multiplexer. I know I can work around the problem by using rcc_pclk1 or per_ck as my clock source in

Hi,Please add buttons at the top of a profile that jumps to a forum. And/Or a menu item with list of user selected forums.It takes too many clicks to switch/access forums.Thank you.

Is there any example will guide about ADC being triggered with timer and being transferred to RAM with DMA for STM32H5 series?

Hello ST team, I've encountered some serious issues after updating NanoEdge from version 4.6.0 to the latest 5.0.0 version.All my training results from version 4.6.0 have disappeared after updating to version 5.0.0. These old training results are important for my paper. How can I recover them? I only performed an update operation, why was all the data lost?When using NanoEdge version 5.0.0, clicking "create" on any training project doesn't produce any response or pop-up window. I've tried this on two different computers with the same issue. How can I solve this problem? I want to create a new project and start training.Is there a way to keep old versions of NanoEdge or get an upgrade notification? Yesterday during my group meeting presentation, NanoEdge suddenly prompted me to upgrade, and it would exit if I didn't upgrade. However, the upgrade process was extremely slow - I waited for tens of minutes when it should have only taken a few minutes with my internet speed. 

prefer using a package manager to install and update toolchains

Hi,I am implementing USB CDC ACM on my custom board using STM32C071x series of microcontroller. It is currently not working and looking at other post on community I observed that one of the problem is of missing call to function - HAL_PWREx_EnableVddUSB(). is this function call necessary for all series of STM32 microcontrollers? If that is the case then it is missing in my auto generated code from CubeMX. I also tried manually adding it but it is giving me compilation error - 'undefined reference to `HAL_PWREx_EnableVddUSB'Thanks,Pradeep
