Hi Community, I installed CubeIDE on two Windows 10 computers. In both cases there is no Intellisense. Does it have to enabled explicitly?

On the Nucleo-H743ZI board, I'm trying to configure TIM3 with a 10 us period. With the internal clock source at 200MHz, I would expect these parameters to create a 10 us TIM3 interrupt:htim3.Instance = TIM3; htim3.Init.Prescaler = 200; htim3.Init.CounterMode = TIM_COUNTERMODE_UP; htim3.Init.Period = 10; htim3.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1; htim3.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_ENABLE; sClockSourceConfig.ClockSource = TIM_CLOCKSOURCE_INTERNALBut my TIM3 interrupt is occurring every 11us instead. Can anyone see what I'm doing wrong? Thanks for any help.

Dear,For the first time, i use an external SDRAM with the FMC peripheral of the STM32F446.I succeeded to describe a in the linker script to place specific data in this section.BUT this section is present in the output file (.hex) when I build my code. Because it's a section with just uninitialized data, this section must not be in the output file.Maybe I did something wrong ???In linker script :XRAM1 (xrw) : ORIGIN = 0xC0000000, LENGTH = 1920K   /* External RAM section */ .xram1 : { *(.xram1*); } >XRAM1In header Cpp file :class SDRAM { public: .... __attribute__((section(".xram2"))) static u8 sData[10][10][10][10]; .... };  I use Atollic as IDE with gcc.

​Can someone point me in the direction where I can find a document giving the I2C register locations to control the VL53L0X. I am trying to read out ranges using an FPGA and the standard I2C bus but all I have found is the device address is 0x52.Thanks

Hi,I'm not sure how I should go about designing a widget class that can be reused in various projects? Say I want to create a keyboard class (container?) that can be easily imported in all my projects that need one, how should design it?Thanks in advance.

I'm trying to add a custom GATT service to a HID peripheral. I'm using a BlueNRG-2 and following the BLE_HID_Peripheral example. In the hidService_Type ther are two fileds that look like they might be used for this. They are includedServiceEnabled and includedService. I think I need to set includedServiceEnabled to true. However, I'm not sure what includedService should be. The type for this field is includSer_Type. This type ahs three fields:uuid - which only holds 16-bits. How can I provide the 128 bits needed for a custom service?start_handle - where do I get this?stop_handle - where do I get this?Are service handles assigned in order such that there is a first and last?If I have one service, would start_handle and stop_handle be the same?Also, should I add the custom service and characteristics using aci_gatt_add_service and aci_gatt_add_char just prior to the call to hidAddServices?

both ports set to CDC using internal PHYHeap set to 0x2000VBus sensing not utilized, but that should only affect 1 port, not both.using Cube_MX on this new project.Is there example code for H7 using USB ?

Hi, I'm using the STM32F334K8T6 andI'm using EAGLE 9 to create PCBs.https://www.digikey.com/product-detail/en/STM32F334K8T6/497-14953-5-ND/4989175?WT.z_slp_buy=stm_stm32f3Does ST provide PCB libraries which I can use on EAGLE?Where can I get them?Since TI provides their drawing using Ultra Liberian,https://webench.ti.com/cad/cad.cgiI was curious whether ST provides the drawing as well.I wish to get the STM32 MCU libraries and use the footprints, please.

I have a problem with this sensor configured for 2g scale and interrupt on INT1 for click detection.If I set threshold register in a range 5 to 7 I receive a lot of interrupts as soon as the sensor is slightly inclined on X or Y axis.Please see below I2C dump of registers configured.NOTE: This question and answer originated from a customer support case which was handled by us. We regularly review support cases and add any helpful ones here for all to benefit from.        

Hi, I'm using the example "BLE_SensorDemo_Central" from SDK to design a PoC to scan iBeacons devices.I can't figure out why the scan procedure is too slow. I have two iBeacon devices near by the BlueNRG-1. They are sending iBeacon messages in 3Hz, but the BlueNRG is not fast enough to get the packages.What am I doing wrong?I understood that the method "Master_DeviceDiscovery()" set the scan parameters, right? I couldn't find on documentation the min or max for scan interval or scan window.What do I need to do to get best performance from BlueNRG-1 on scan mode? I don't need to connect, just get the iBeacon messages.Thank you!

First of all I am very new to application development with ST-Electronic device shields.I have following devices with me,X-NUCLEO-NFC05A1 - NFC expansion shieldNucleo 64 : F401RE board.I was doing some samples with ARM Mbed online compiler.I want to access external NFC tag's content via NFC05A1 expansion board in ARM Mbed. However, I was not able to find a correct library for NFC05A1 expansion board in ARM Mbed. But, I found a sample and a library for different version of NFC shield : https://os.mbed.com/components/X-NUCLEO-NFC01A1/ and this is not compatible with the NFC05A1.I was wondering whether there is a library which I can use in ARM Mbed to access NFC functionality in X-NUCLEO-NFC05A1 board.Note: I found a following CUBE sample for this expansion board but, I do not think this can be used in ARM Mbed as a library.https://www.st.com/content/st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm32-embedded-software/stm32cube-expansion-packages/x-cube-nfc5.html

its needed, but its not there :(>make: *** No rule to make target `../../../../STM32Cube/Repository/STM32Cube_FW_F7_V1.14.0where do I find this file ?

Hello,I'm using ST25R3911 with my own board, and I need to read a ISO14443A/NFC-A T2T card, like NTAG213/6. I'm using the ST25R3911 DISCO FW 1.28 files.The card is correctly detected, and I'm able to read the UID, but when I try to select the sector to read using the rfal_t2t files (rfalT2TPollerSectorSelect function) I obtain a 04 error due to timeout.My function:bool PollNFCA() { ReturnCode err; rfalNfcaSensRes sensRes; rfalNfcaSelRes selRes; rfalNfcaListenDevice nfcaDevList[EXAMPLE_NFCA_DEVICES]; uint8_t devCnt; uint8_t devIt; bool found = false;   rfalNfcaPollerInitialize(); // Initialize RFAL for NFC-A rfalFieldOnAndStartGT(); // Turns the Field On and starts GT timer //---------------------------------------------------------------------------- // Perform NFC-A Technology detection err = rfalNfcaPollerTechnologyDetection( RFAL_COMPLIANCE_MODE_NFC, &sensRes ); // Poll for nearby NFC-A devices if(err == ERR_NONE) // NFC-A type card found { err = r

I follow the instructions here:https://docs.zephyrproject.org/latest/boards/arm/nucleo_wb55rg/doc/nucleowb55rg.htmlI've built the .elf file, how do I flash this to my board? I see my board connected as a drive, I copy the elf file over but when I disconnect and reconnect it has disappeared.I'm on linux.

Using RF I am able to activate mailbox/fast transfer mode using this process :Present passwordWrite static GPO => replace former GPO with 0xB0Write MB Mode => 1Write MB CTRL Dyn => 1Now I need to deactivate the mailbox with I2C. I am following this process :Present passwordWrite static GPO => former GPOWrite MB Mode => 0I can see the values are right in the register. However whenever I approach the ST25 app on Android, it says the mailbox is still activated, preventing me from being able to write anything on the EEPROM (error returned : 0x0f)Is there something I am missing ? Thanks

Hi all, for those who are trying to use an external power supply on the STM32F746G-DISCO, yesterday we found that on the two cards we are using for our development, the solder on JP2 connector creates a shortcut... preventing the card to be used that way.

Hello,Is there a way to change the color of a botton directly from the code? Thanks.

Hello,Where can i find the bsdl file for STM32F107VC?Thanks,Alexandre

I have a problem with QSPI. I try everything, but program doesn't work.I am using STM32F746 series MCU and I am trying to interface with a quad spi memory from Winbond (W25Q16JV).I am following the example found in this location:(I modified some interface like STM32F769⇒STM32F746)STM32Cube_FW_F7_V1.15.0\STM32Cube_FW_F7_V1.15.0\Projects\STM32F769I_EVAL\Examples\QSPI\QSPI_ReadWrite_DMA\SrcSo far, I have been able to enable writing by executing 06h(Write enable) command and pool for the QE bit setting(set to be 1) by using command 31h(Register-2 Write).This seems to work.But, I read the QE bit using command 35h(Register-2 Read), QE bit never be 1.Could someone know this solution? I want to get how to set QE bit setting to be 1.My enviroments1) MCU:STM32F7462) Flash ROM:Winbond (W25Q16JV)uint8_t ucRegister2;static void QSPI_QuadEnableCfg( void ){ QSPI_CommandTypeDef sCommand; QSPI_AutoPollingTypeDef sConfig; /* Read Volatile Configuration register ----------------------

Hi Martin,I started to create a basic window with a background bitmap and some widgets, buttons and sliders but found I could not resize the widgets. I am missing something basic. In response to my last post you mentioned stickies, what are they?Kind RegardsMikeZ

Hello,I have gone through the KB articles of TouchGFX. But I think they are very shallow. Not able to found how memory management is done. I know a good graphical system needs lots of RAM so touch gfx needs external SDRAM. Ok I have got SDRAM. But how it uses the SD RAM? Normally software uses dynamic memory allocation for such purpose (example when it allocates memory for screen buffers or caching(loading) bitmaps). But in embedded system we cant easily use dynamic memory so some kind of tricks are implemented. I am not able to find out how TouchGFX uses dynamic memory? Where we define the area which is used for caching bitmaps.

Hello,I have donwloaded the STM32CUBE FW pack for F1 modules.I tested 2 of them: a UART_PRINTF example and a PWR example, for the F100 Discovery board.Both examples work well, and I want to add UART capability to the PWR example.How does one do it?I tries to copy all relevant files and relevant code to the PWR example, and it builds and runs without errors, but upon printing, nothing happens.

I've followed this article to configure a CubeMX project with TouchGFX graphics and IAR Embedded Workbench: https://touchgfx.zendesk.com/hc/en-us/articles/360019884752-Configuring-STM32F746G-DISCOI got it working several times, but suddenly the linker gives an error:Error[Lp011]: section placement failed       unable to allocate space for sections/blocks with a total estimated minimum size of 0x10'1d00 bytes (max align 0x4) in <[0x9000'0000-0x9010'0000]> (total uncommitted space 0x10'0001). Error while running LinkerMy application consists of a clock (made with this tutorial: https://touchgfx.zendesk.com/hc/en-us/articles/360018667192-Step-1-Setting-up-the-two-Screens) a using some hardware pins.
