Hi,I want to use STME32L152 with LSE for RTC.I set the bit LSEON in the register RCC_CSR but the bit remains always 0. I proceeded the same with LSION and it is working well.I disable also the bit LSECSS and behavior is the same.The LSE oscilator didn't start.There is another condition to starting LSE?Thank youConstantin

Hello,I have been having problems with my debugger losing connection when i set the CM7 of my STM32H745 into CSleep mode. I have the DBGMCU flags set to enable debugging in low power, but I assumed I was still doing something incorrect with the domain low power modes or the flash memory.However, I made a minimal example without the STM HAL and low power debugging worked as expected. The debugger did not lose the connection after the CPU entered CSleep mode.I tracked it down to line 137 in file "STM32Cube_FW_H7_V1.5.0\Projects\NUCLEO-H745ZI-Q\Templates\BootCM4_CM7\Common\Src\system_stm32h7xx.c":SCB->SCR |= SCB_SCR_SEVONPEND_Pos;Based on the comment immediately before and the seeming intention of the line this should probably be: SCB->SCR |= SCB_SCR_SEVONPEND_Msk;And indeed making the change allows the low power debugging to behave as intended with the debugger not losing the connection.That line of code is all over the example and template sources as per the attached file, bu

When I change the name of a screen or container, I get compile errors. I believe this is because TouchGFX won't delete code under the "gui" directory to keep from wiping out user changes. I can deleted these manually and build under Visual Studio, but as soon as I generate code in TouchGFX, it recreates these files and the compilation fails again.How can I delete or change these names in a way that doesn't break TouchGFX?

I need to display a filled graph, where some portions of the graph needs to be displayed in different colour than the basic colour of the graph. The graph is displayed using a canvas widget, created in touchgfx 4.10.0. In the drawCanvasWidget function, the graph is drawn using lineTo commands. (The filled effect is created by drawing a series of vertical lines adjacent to each other). The problem is that colour of the line can not be changed in the drawCanvasWidget function as the function is const. So, how can the part of graph be drawn in multiple colours? A sample of the graph is in the file attached.RegardsMathews

Hi,I'm trying to find out whether there is any way to maintain internal pulldowns on pins in standby mode on the STM32F407.I suspect that this is not the case but haven't been able to find a definitive answer in the documentation. Any help would be appreciated.Thanks!jay

I am attempting to create a program to implement SPI communication from my STM32H753XI MCU, all I did to do this was start a new project in Keil's uVision and generate the code from Cube after selecting my pinouts.Once my code was generated, however, I attempted to compile it and got 30 errors regarding identifiers that haven't been defined. These appear to be structs and enums from other header files that haven't been included in my project when I generated the code, I've listed examples below.C:\Users\User\AppData\Local\Arm\Packs\Keil\STM32H7xx_DFP\2.3.0\CMSIS\Driver\SPI_STM32H7xx.h(284): error: #20: identifier "SPI_HandleTypeDef" is undefined"" "" error: #20: identifier "HAL_SPI_STATE_ABORT" is undefined"" "" error: #20: identifier "HAL_SPI_STATE_RESET" is undefined"" "" error: #20: identifier "HAL_SPI_STATE_ERROR" is undefinedThese are just a few of them. Is this a mistake I made when generating the code from CubeMX?

Before I enter the stop mode 2 I save all the GPIO MODER, OSPEEDR and PUDPR registers, configure pins as analogue (to save some power) and enter the STOP mode 2. When I exit the stop mode (I use RTC wakeup and GPIOs for that) I restore the above registers. Vvery second exit the GPIOA is disconnected from the physical pins. I can read and write the GPIOA registers (I was testing it using debug interface and the UART trace as well) but there is no effect when I write the ODR register. ODR sets correctly, but there is no action on the appropriate pins. It happens every second exit from the STOP mode. So the first exit all works fine, when I enter and exit the stop mode for the second time it does not, the third time all is fine and so on. Other ports work fineI have tried almost everything. Resetting, disabling and enabling the port. Adding the barriers delays and other magic, but unfortunately nothing works.Do you have any clues?

I'm using the Nucleo-L4r5zi I can't send a receive a simple message using USART Communication, Which pins to configurate on the Cube MX ? should i use an FTDI (usart to usb cable) ?

Bringing up BlueNRG2 (in network co-processor mode). Using the following call on the host MCU (after aci_gap_init():(aci_gatt_update_char_value_ext(...)For setting the Device Name characteristic (0x2A00) of the Generic Access Service (0x1800) seems to be limited to 7 characters. Setting a string of 8 or more returns a bad parameters code. I realise there's a packet size limitation (unless BLE >= 4.2 + MTU reconfigure after connection) but 7 seems a bit short, is this simply a limitation imposed by ST in the BlueNRG2 stack or am I missing a call?The complete advertised name I have set is working fine (13 chars).I notice the example STML4 projects use small device names.

On 32F429IDISCOVERY, a set of resistors selects the onboard LCD mode:As can be seen, R35+R41 determine one signal's state, R36+R42 the second signal's state (and the other resistors the rest of the signals).However, on silkscreen of the actual board, R35 and R36 appears to be swapped, as R35 is marked to be not next to R41 but next to R42, and vice versa fr R36:also confirmed by looking at the gerbers:ST, can you please comment/correct in next revisions of the board?Thanks,JW

Following prototyping with discovery board (STM32F746NG-DISCO), I am going to start my own design.Except, I need to change:1- The display, I will replace the 4.3" inch display with another with size of 10.1".2- I have to change the package of the MCU to the LQFP208 package.For the 1st part. I don't think it will be a much of an issue. As long as the new display is driven by the same interface RGB24. The rest is a matter of changing the parameters like width height sync. rate etc... However, if I am missing something please let me know.For the second part. I am very worried about changing the MCU package. I know it has the same peripherals and so. But during the design of the new board. I need to know exactly what are the peripherals and middlewares that I need to activate from CubeMx to be sure about the pins in use during tracing.Can you please tell me what are all the peripherals and middlewares I need to check so I don't miss something?And in general, what else I need to pay at

Hi, is it possible to independently choose the pins related to the SPI or are there constraints?For example can i set this pin :SPI5_CP_CLK PH6SPI5_CP_MISO PH7SPI5_CP_MOSI PF9Thank you!

Hello,I used the Nucleo STM32WB55 board to test the STM32WB55xx current consumption.I took the PWR_STOP2_RTC example from the STM32Cube MCU package for STM32WB Series (v1.2.0)With STM32CubeMx v5.3.0 I re-generated code for Truestudio (I am using Truestudio v9.3.0) and followed the readme for the board setup.I measured 113µA on JP2 (when the chipset is in STOP2 mode), while I expected something close to 2µA as per the datasheet.What is strange is that I have the same consumption if I change the code to use STOP1 or STOP0 mode instead of STOP2.What could be wrong in my setup?How much current should the board consume with this example code?Thanks & Best Regards,Julien.

Hi Sir,In the MB1355 schematics what is the purpose of two antenna's?How to calculate the unfitted capacitors ? what is the purpose of band pass filter here?

If can, please share the physical connection diagram (two Analog voltage sources to single pin micro controller ) and sample code for that.

From the website， it shows there are 6 SPIs in STM32F429VIT6, but from CubeMX Connectivity​ list, there are only 4 SPIs in STM32F429 series.So which parameter is correct ?B.R.Billy

I know this is a dumb question, but I've googled it and can't get an explanation. What is the "debug" column in the MAP file?Also, it's alarmingly big... using Keil is there a setting I should use to compile without whatever is taking up that space? I don't see the typical debug/release config settings.Thanks for the help.==============================================================================     Code (inc. data) RO Data RW Data ZI Data Debug   206256 18706 599208 7644 443828 3533745 Grand Totals 206256 18706 599208 1628 443828 3533745 ELF Image Totals (compressed) 206256 18706 599208 1628 0 0 ROM Totals

Hello everyone,I spent the whole day trying to run the software STM32 Cube monitor (version 1.0.3) on my computer.I have tested with a Linux Mint and a Debian distribution and with the version 11 and 12 of the Oracle Java JDK but the problem is the same.When I run the software I get the message Error: Could not find or load main class com.st.mtt.guipower.MainAppCaused by: java.lang.NoClassDefFoundError: javafx/application/ApplicationI use the same command of the shortcut to run itjava -jar STM32CubeMonitor-Power.jarDoes anyone know what's the problem? Or if it's possible to download a previous version of the Monitor to test?Thank you very much for your help.

I am really confused that is it necessary or not. Because if I am going to the series STM32F030 these controller doesn't have in built EEPROM memory.

HiI am using the ​NFC5 V1.3.0 for the STM32L053R8-Nucleo as an example to port the RFAL library for using with either a STM32F051 or STM32G071. I replaced the Systick/NVIC/EXTI/GPIO/SPI Hal and everything seems to work, except that when I want to read out the UID of the used tag NFCV-15693 only 5 Bytes are read from the FIFO. On the Nucleo-Board the detection works fine. Do you have any idea where my problem is?Attached is the SPI communication with the not working MCU.Thanks in advance.Best regardsPatrick

Hi, I have two types of MCUs that I am building a board with. One is labeled as STM32WB55, while the other one is ES32WB55. Is there any difference between the two? I could not find any information on the ES32 chip in my Googling. I am having trouble connecting to the chip using an ST-Link. Does it have anything to do with the fact that I am using an ES chip? Thanks.
