STM32H7B3I-DK - Discovery kit use NX3215SA-32.768KHZ-EXS00A-MU00525 Crystal. Crystal Load Capacitance is 6, 9, 12.5 pF but STM32H7B3I-DK - Discovery kit use 1.5pF. Why it use different load capacitance.

Good morning, I am thinking to drive a LCD backlight with ic STCS05 and to control it with enable and pwm signal from a cpu. Led driving voltage of leds matrix of my LCD is 16.5V with 140 mA typical current (see picture attached). Do I have to supply STCS05 and led with a regulated 16.5V power supply (Vin in attached picture)? Thanks in advance. Best Regards. Enrico

I am using below componnet toolsMCU: STM32H7B3IIT6IDE: STM32CubeIDE Version: 1.9.0CRYSTAL: RT3215-32.768-12.5-TR ( 32.7680KHZ 12.5PF)I work with internal RTC. I will use for clock. But RTC clock behinds real clock. While the product is running, the lag increases even more. But when the product is turned off, when it is turned on after 2 days, the rest continues as it was 2 days ago. In other words, I am experiencing the lagging event while the product is running. When the product is turned off, there is no lag.

While debugging an application on the M0+ core of a STM32WL55JC device, the debugger showed what appears the incorrect execution of an ARM machine instruction.The codesnippet at the beginning of the execution is shown in Image #1:(the original C code compiled is a trivial "switch" section, but this is irrelevant)Everything proceeds as expected until the instruction shown in Image #2. The execution of the "ldr   r3, [pc, #396] " instruction @0803845c, however, seems to yield an incorrect result (as shown in image #3):expected -> r3 = 0x80385ec (as also reported in the comment placed by the compiler)obtained -> r3 =  0x803a868From the memory dump (image #4), the opcode of the instruction appears to be correct according to ARMv6-M Architecture Reference Manual (DDI0419D_ARMv6-M_arm.pdf), section A6.7.27, p.

Hi!STM32CubeIDE 1.8.0 won't start on a machine I and my colleagues are working on.Unfortunately, only the following error dialog window pops up:It's quite hard to debug the issue without even having a log file.Starting stm32cubeidec.exe from command line yields the following output:H:\>C:\ST\STM32CubeIDE_1.8.0\STM32CubeIDE\stm32cubeidec.exe java.lang.IllegalStateException: Error initializing storage for Equinox container. at org.eclipse.osgi.internal.framework.EquinoxContainer.<init>(EquinoxContainer.java:110) at org.eclipse.osgi.launch.Equinox.<init>(Equinox.java:53) at org.eclipse.osgi.launch.Equinox.<init>(Equinox.java:46) at org.eclipse.core.runtime.adaptor.EclipseStarter.startup(EclipseStarter.java:315) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:251) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.j

Good day,On a brand new SMT32WB5MMG MCU, I have found that the One-Time Programmable area is not empty. See the image. The OTP area starts at 0x1FFF7000. There is also some data right before the OTP area - what is that doing there as well?For context, I'm using the STM32WB5MMG in a custom application (i.e. not a NUCLEO board). I have seen the same issue (and the exact same data) on two different boards.I did not encounter this issue when using an STM32WB55RGV6 previously.Has anyone else encountered this?

Hi there,on the EVSPIN32G4 are the STM32G431 MCU and the STM32F103CB MCU. Currently I only have the STM code generation programmed forSTM32G431 MCU. Is it possible to program the STM32F103CB MCU with the STM Workbench too, so that I can e.g. control the AD converters from this STM32F103CB MCU too?And can i transfer data from one MCU to the other?Thanks and best regardsBernd

Hi @Sebastien DENOUAL​ ​ I have example code BLE sensor demo in that they have 3 sensor value and one free fall characteristics. One is acceleration , temp, press, and free fall. The acceleration sensor value is Conntiniously updating over the app one we enable the notifications is enable. But the temp and press value is read only they are not updating over app one we enable the notifications. I wanted to update temp and pressure value Continuesly once we enable the notifications. How I can do that in example code. What change I have to make in BLE sensor demo example. ​@Sebastien DENOUAL​ @Salvo​ @Salvatore DI SALVO​

HelloThe new version 1.3.0 of STM32CubeMonitor is available on st.com.You can download it on https://www.st.com/en/development-tools/stm32cubemonitor.html Click on "Get latest" to download the version 1.3.0. What are the changes in this version ?We have updated node-RED : STM32CubeMonitor is now based on the version node-RED 1.3.7 , with dashboard 2.29.0. Other dependencies have also been updated to have an consistent package.Many users have raised question about CSV export. We have proposed some solutions using node-RED nodes. (wiki export csv) This is very flexible, but need to add many nodes in the flow. So we have added an option to save the data directly in csv format in the processing node : It is now very easy to export data in csv format. Some users would like to be notified in the dashboard when the symbol file has changed. (symbol file = .elf .axf .out....) There is now a new output on the variable node which can be used to connect a notification box. When the file has change

HelloA new version 1.4.0 of STM32CubeMonitor is available on st.com.You can download it on https://www.st.com/en/development-tools/stm32cubemonitor.htmlClick on "Get latest" to download the version 1.4.0.What are the changes in this version ?The management of multiple probes has been redesigned to use multiple threads in the computer. On previous versions, all probes were managed by a single thread, and the acquisition speed was reduced when new probes were added. With the new architecture, each probes use a separate thread and performances are improved. This change also provide a better accuracy of acquisition with a single probe because it is managed in a dedicated thread. Node-RED® is updated to version 2 (V2.1.5) :Node-RED® dashboard updated to V3.1.3. Update of additional ui nodes (serial-port 0.15.0, ui-led 0.4.11, finite-statemachine 2.1.3)Note : The control messages of node-red-contrib-finite-statemachine change from v2.1.0 onwards. Users using the FSM node

Details: In the reference manual for stm32f303vet (rev 8) Figure 14, the PLL source is HSE by default if HSE is selected as source. In Page 140 bit Bits16:15, it says the default is HSE/2 and so on.This point is important since different stm32f303 variants have different diagram about PLL source.

Hello, I ported wokring code from STM32F4 to STM32H7 (STM32H7A3NI). So far most is working as expected, however on SPI2 used as I2S the circular RX DMA1 Stream3 does not start. NTD remains on its initial value 0x800. The SPI2 has RXP and OVR set. The TX DMA1 Stream4 works as expected. The DMA buffers are aligned and in DMA-reachable memory.HAL_I2SEx_TransmitReceive_DMA (1.9.1) is used. The init order is not as described in the Reference Manual RM0455 Rev 7, page 2115. I also tried the Ref.M. order without success.The following image shows the SPI2 registers after start The following 2 image show the state of the DMA1 Steam3 (RX) and Stream4 (TX) about a second from each other. The Stream3 NDT stays on 0x800 whereas Stream4 counts. What could prevent DMA1 Stream3 from starting? Any help appreciated! Thanks in advance.

HiI had a problem where the GDB Server couldn't connect to the assigned port 62325. Using Windows Sysinternals TCPView I ascertained that SearchApp.exe was using that port.I changed back to the default port and all was well.The question I have is there anything special about the defualt port number, or has it been arbitrarily set to the port region above 60000 as there don't seem to be any standard port definitions in this range?RegardsRob

Hi I moved a code that was working on STM32CubeIDE v1.8. But after update STM32CubeIDE v1.9 I am facing a new issue that I have never see before in STM32CubeIDE v1.8.0!I compared what was before and what we have now, see screen...Maybe to me need only turn on "Auto Negotiation" in main.c and ping will start working but, I don't know how to do it?Could someone tell me why code do not initialize MX_LWIP_INIT (); ? Bellow my simple code main.c/* USER CODE BEGIN PV */extern struct netif gnetif; /* USER CODE END PV */ while (1) {   /* USER CODE END WHILE */   /* USER CODE BEGIN 3 */    ethernetif_input(&gnetif);    sys_check_timeouts(); } /* USER CODE END 3 */}

Im' following this tutorial of STM32WB55: https://www.youtube.com/watch?v=CKYWy7LKL68&list=PLnMKNibPkDnG9JRe2fbOOpVpWY7E4WbJ-&index=19&ab_channel=STMicroelectronicsAll is fine until I try to generate code. It gets stuck at the moment of "Copying libraries files...". What I have tried is not to generate code Under Root. But the problem after doing this is that I can't compile the project. And returns to me 9 errors, all of them sayng that one of the files has "Invalid arguments".Is this a problem of CubeMX? I have tried it with the same versions that the tutorial use:-Cubeide 1.7-CubeMx 6.3-STM32Cube_FW_WB_V1.12.0And I also tried it with all the latest versions-Cubeide 1.9-CubeMx 6.5-STM32Cube_FW_WB_V1.13.2And I always have the same results.

Hi, from the micropython repository there is a note on a problem regarding address resolution, it is reported at this link.Are there any details about it? is this a known and solved problem? or still open?Thanks and regards

The quartz used for HSE on the nulceo-wl55jc and on the reference design for stm32wl is NX2016SA 32MHz EXS00A-CS06465, which has a 10pF load capacitance (the BOM for reference design even mentions 8pF, but the quartz reference is actually 10pF).The minimal value for SUBGHZ_HSEINTRIMR is 11.3pF, so higher than the load capacitance of recommended quartz.Does it works thanks to the fact that parasitic capacitance is lower with internal bank capacitance? Still, in such a case, it seems that trimming is only possible in one direction?Is 10pF really the recommended value or is it better to go for a quartz with a 12, 16 or 20pF load capacitance?Thank you
