Hi there Touchgfx team! I have this UI requirement of a line with a drop shadow: In Figma the line has 3 pixels. I found another post to do it with the alpha value but it doesn't feel the same. I'm using a line with a width of 3. Any ideas? Thanks a lot in advance

Hi there Touchgfx team!I've this ui requirement: A header with battery, date/time, battery, and extra icon. I also have 15 different screens. The model receives a signal from the backend and thats how it knows that it needs to show the USB icon. I know how to do a notify from model -> view, and I know I could do this for the 15 different screens. The problem I'm facing is that the USB icon needs to appear in the other screens if the user goes to a different screen. I know I could also setup a flag in the model and get the vale in the setupScreen() My question is: is there an easier way to do this? I would like to avoid creating 15 different propagation functions for the USB, and other 15 for the other icon. I was thinking about creating a custom container and updating it from the model just once, and somehow all the views with the container will update. I have the same question for the "date/time" text. At this moment, each view has a function that calls the

I am using STM32F105xx family, working with HAL_SPI API.  I have discovered that the call to HAL_SPI_Receive_IT causes whatever data is in the provided buffer to be clocked out on MOSI.  This issue is also discussed to some extent in this thread, but that thread is more focused on fixing the system behavior than discussing whether it's actually a bug in HAL.  So...am I crazy or is this a bug?  If I call a "Receive" method that only takes a receive buffer, I shouldn't expect it to transmit that data, should I?I'm working with TI's ADS1258 ADC which has a "direct read" mode meaning no command needs to be sent to read the next conversion result (technically, it watches the first three bits of MOSI; if they are all 1s or all 0s, it ignores the rest of MOSI and continues clocking out data on MISO for 32 bits).  If there is stale data in the buffer provided to HAL_SPI_Receive_IT, and that data happens to have a first byte that the ADS1258 recognizes as a co

I'm trying to program a P-Nucleo WB55 USB Dongle (PCB number MB1293C) with the BLE_TransparentModeVCP example. Using STM32 Cube Programmer: 1. Load FUS V1.20.0 - stm32wb5x_FUS_fw.bin at 0x803A0002. Load  BLE Stack V1.- stm32wb5x_BLE_Stack_full_extended_fw.bin at 0x80110003. Load BLE_TransparentModeVCP_reference.hex (from P-NUCLEO-WB55.USBDongle directory) at 0x800000 I get a single green LED on the board and it appears as a COM port on the PC, but STM32CubeMonitor-RF is unable to connect to it. Any suggestions?

Hi, I need help generating an .IOC file through the cube generator. What I need is USB Host FS. I'm having trouble getting it to work, specifically, there's no voltage on the VBUS output.I want to mention that I was able to create a USB Host HS that works and outputs voltage.Thank you!Itzik

Hi folks,I am trying to use the hardware-AES of the STM32WLE5JC, but I get weird results that do not match the expected values. I am comparing my STM-implementation against RadioLib's Crypto which is based on tiny-AES-c and AES-CMAC. RadioLib's implementation yields results that completely match verification tools such as this one.I am investigating two things: 1) single-buffer ECB encryption, and 2) CMAC calculation based on ECB encryption. My observations are as follows:encrypting a single ECB buffer yields incorrect results,calculating CMAC (which uses ECB encryption as subroutine) is OK / as expected,calculating CMAC and then a single ECB buffer yields expected results** I only get OK results for buffers <=128 bits.Example:  uint8_t key[16] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 }; RadioLibAES128Instance.init(key); uint8_t data[24] = { 0 }; uint8_t out[24] = { 0 }; // RadioLibAES128Instance.generateCMAC(data, 24, out); RadioLibAES128Instance.encr

I was performing simple arithmetic calculation, and wanted to check the data gets stored in Flash and SRAM memory.While checking the memory browser all I see is ?????. Could anyone guide me, what's the issue here?

Hi,I am working on interfacing an STM32F405 with the ASM330lhh and have been able to utilize both I2C and SPI communication to the chip. I am able to turn on and read the accelerometer and temperature as well as the status bit become 0x05 but trying to turn on the gyroscope with and without the accelerometer already activated I get no status bit and no data is outputted via the gyro's registers.I am writing 0x11,0x60 to turn on the gyro and reading the registers starting at 0x22. one thing to note is that when turning on the gyroscope while using I2C the entire line breaks after modifying the register, on SPI this doesn't happen but there is no change in the gyro data.

... I'm using ASM330LHH chip, I'm using the SPI communication method, when I initialize the write to these registers, I confirm that it has been written, I go to read the STATUS_REG register, and I find that it has always been 0, and then I go to read the values in the acceleration register, and I find that these values have not changed, what is the problem?

Hi there Touchgfx team! I have about 15 different screens. I also have a modal that says "battery critical level". I know how to propagate a notification from the model to the view to trigger this modal. My question is: is there an easy way to do this for 15 different screens? or everytime I need to override the notification function in each screen? Thanks a lot in advance

Hello!I am having issues with firmwares on the P-Nucleo-WB55. I started from blank code from CubeMX using AzureRTOS/ThreadX with an added layer of CMSIS and took inspiration from the HeartRateFreeRTOS sample (as it uses CMSIS too). I am currently using the BLE/ZigBee FF dynamic firmware as the project will include communication with ZB devices later on. The ZB stack is not initialized.I refactored some of the code from the sample and have been able to see all the proper exchanges on the SHCI/HCI layers being successful: getting the firmware version, enabling the C2, resetting HCI, setting the default PHY, configuring various settings (public address, IR/ER, TX power level), enabling GATT then GAP, updating the device name and appearance, setting the IO capabilities and the authentication requirements.Starting advertisement begins with `aci_gap_set_not_discoverable`, which fails (error 0xC/not allowed) as expected as the device is not discoverable by default.The next call is to `aci_gap

Hello, I am attempting to have a two stm32 nucleo boards communicate by sending and receiving can messages.  My goal is to have the PA5 LED of the STM32 f446re blink when a can message is received. I know that the canbus must be configured to classical can which the baud rate must match both boards. The two boards I am using are the stm32 f446re and the stm32 h723zg. Currently, I suspect an electrical issue as I have been running a two 220 ohm resistors in parallel with the CAN_H and CAN_L lines, but when in a recessive state the CANH and CANL both read 2.2V and fail to change when in the dominant state. However, I want to ensure that the software is also not the issue. I am also using two waveshare SN65HVD230 can transceivers as well. Any help is appreciated, and I have attached a picture of the set up (ignore the 7 segment) as well as each project's codebase. 

Hi,in a setup on STM32H725 where TIM1 ETR triggers several DMA activities, I observe an effect while debugging that I would rather like to avoid:Looking at the NDTR of the three DMA, it seems that one extra ADC run (or at least the related DMA transfers) occurs each time the device is halted for debugging. I do not understand how this can happen.Basic setup: TIM1 is started by ETR. Two DMA channels capture related register values to circular buffers and are triggered by TIM1 TRG and TIM1 CC4 (at CCR4=1). Combined ADC1+2 is triggered by TIM1 CC3 (at CCR3=89). The ADC results (2x 3x 16 bit) are written to a circular buffer via DMA. All DMA are initialized at the same time. The circular buffers are all of the same size.All timers are halted during debugging (flags set in DBGMCU->APBxFZ1)Observation: Normally (without any halt introduced debugger via SWD) the three DMA are perfectly in sync and stay in sync. For example, at each DMA Complete of the ADC channel, all NDTR are reset to the

What is the type of internal (mechanical) structure of LSM6DSO32 gyro sensor? (a photo of the internal structure would be beneficial). The reviewer asked us about this during the review process, and we couldn't find such information in the manual. Best regards,Dominik Sierociuk 

Hi,I have a custom board with a STM32L4 powered at 1.8V. I program it without problems with a STLINK-V3MINIE.Now I want to program it with the stlinkV2 of the NUCLEO -L4R5ZI-P (I have cut it, removed CN4 and connected pins 1,2,3,4 and 5 to CN5):I can connect and read the memory, but if I try to program, the flash is erased, but not written and the IDE shows this error:What could be the problem?Thank you very much! 

Hello everyone,I'm currently using the STM32F401CCU6 in my project, but it's proving to be oversized for my application, both in terms of physical package and power requirements. I'm hoping to switch to a smaller STM32 microcontroller that maintains as much compatibility as possible with the F4 series, so I can avoid major changes to my implementation.Here are my main requirements:12-Pin Package (a few more pins are okay, but aiming for a minimal footprint)RTC Support with a 32.768 kHz external oscillatorSPI Communication capabilitiesLow-Power Modes (ideally STOP, STANDBY, or similar ultra-low power options) Any recommendations for STM32 microcontrollers that meet these criteria? I’d love to hear about your experiences with similar switches, too!Thank you in advance! 

Hey folks.What I do is this: I get 14 ADC measurements on different channels, than use DMA to store them into an array. When this is ready an interrupt flag is raised, I make a copy of that array and send it via UART. There is a timer to control the ADC. At some point I do transfer back an UART message that I use to update my ARR register of the timer. This set up works from time to time, but most of the time, especially on higher values, DMA that I use with ADC stops rising the interrupt flag, and no new ADC values are produced. Does anyone have similar experience?THanks! I did try to disable the UART, ADC, and TImer before updating ARR, but to the same result.

I Use STM32CubeExpansion_NFC3_V2.1.0 for emulate card with NUCLEO-L476RG and X-NUCLEO-NFC03A1.I can't find a example code for NDEF emulation card.Does anyone have a example code for NDEF Emulation card ?Card emulation feature is not written in the datasheet of CR95HF,but it's written in the datasheet of ST25R95, and they use the same sample project. So can anyone tell me the difference between CR95HF and ST25R95.Does CR95HF support NDEF card emulation featuren?  Best Regards.Peter G

Hello,I am working with the STM32WB5M module and encountering an issue with Zigbee connections between the coordinator (coord) and an end device. The end device successfully reconnects and resumes communication upon waking up from the stop mode. However, if there is a power loss while the end device is in stop mode, it fails to reconnect after the power is restored. I have implemented a filter in the coordinator's code to detect disconnections, but it seems that this filter only detects disconnections when the end device is not in stop mode. When the end device is in stop mode, the filter fails to detect any disconnections. Could you provide guidance on how to ensure the end device can reliably reconnect to the coordinator after a power loss during stop mode? Any suggestions on modifying the filter or any other settings would be greatly appreciated.

I'm working on a project using the STM32WB55 Nucleo Board with the Zigbee_APS_Coord example. I need this specific example because my application communicates at the APS level and doesn't use ZCL.My application also requires a custom encryption key, and we don't use or support install codes. The system works by having the coordinator create a network with a known, configurable extended PAN ID, to which all router devices (no end devices, only routers) connect. Communication is then established using the custom encryption key.I’m providing this background because I’m unsure if I’m misconfiguring the Zigbee_APS_Coord example for my coordinator. My goal is to allow my existing non-STM32 routers to connect to the STM32WB55 Nucleo Board acting as a coordinator. If anyone has insights or can point out potential issues, I'd appreciate the help.FWIW, the routers already connect and work perfectly fine with my existing non-STM32 coordinator. I'm just trying to substitute the non-STM32 coord
