Hello,at the moment i try to read correct accelerometer data with a STM32L010C6 Microcontroller from a accelerometer sensor BMA530. The connection is via I^2C (SDA and SCL) and i programm the Microcontroller with a ST-LINK V2. I took a code from gitHub Platform boschsensortec/BMA530_SensorAPI and changed it because in the common.c data i can´t use the coines commands because the STM32L010C6 needs STM32 HAL-Functions because Bosch use other Hardware as STMicroelectronics. The dev_addr2 = (0x18 << 1) see at https://sourcevu.sysprogs.com/stm32/HAL/symbols/HAL_I2C_Mem_Read#:~:text=SourceVu%20STM32%20Libraries%20and%20Samples,information%20for%20the%20specified%20I2Cand i got it from the BMA530 Datasheet - The default 7

Hi, I have an USBPD sink application created with CubeMX that can be found here:https://github.com/ThiRom/H563NucleoUSBPDSink   The project can be build using cmake. If the project is build using Debug configuration, it works. But using Release it shows timeouts on requests. As you can see below during one millisecond the firmware sends 3 retries and a soft reset.  This problem can be seen with -O2 and -O3 option. It seems that the file usbpd_timersserver.c is not working correctly. I found that function:

[Moderation] Separated from the previous thread, as the STEVAL-ISV019V1 is a different topic. Hi,As the questioner mentioned, the voltage measured on the STORE pin is about 2.416V. Should we charge the battery at this time? What conditions can raise the voltage of STORE to VEOC. Thank you for your reply and your help.

i couldn't find the datasheet here. Does anyone have the datasheet for this part# STHV1600L? or STHV1600?

Hello everyone,I’m trying to develop a new project using an STM32C552RET6 with a TFT display.I’d like to use TouchGFX for this, but I can’t find any instructions in CubeMX2 on how to configure a project as a graphical application.I saw some examples in TouchGFX Designer using the STM32C5, but I got the impression that the integration was done manually.So, does anyone know if CubeMX2 has this functionality?Thanks,Matheus  

Dear ST community, I'm reviewing the Vac sense circuit of STEVAL-7BIDIRCB, where the circuit uses a resistor divider to generate a low voltage of VACN and VACL for MCU. I simulated this section of circuit in LTspice, and here is my result : My Vac input is +/-256V sine waveform and VACL that I'm measuring is +/-900mV sine waveform. Based on my calculation this is a simple voltage divider and I should see +/-1.8V sine waveform. 

Is there a Global Exclusive Monitor connected to the M33 and the A35 cores?Any documentation for it?Thank you

Hello support team, I just received a new AEK-COM-10BASET board and trying to connect Lauterbach debugger with License module for MPC55xx. Question : How can I connect to the board through Lauterbach debugger & SW? Currently the SW (TRACE32) shows error message when I press "Up" button. I have no idea why such "Target Power Fail" error or "Power Down" message is appeared.Also I checked below 11 pin and the measured voltage is 3.3V.

Hi, the extension version is 3.8.0, and it usually takes 5min to load, is that normal? Also, is there any CDN or dedicated server for Chinese users? cuz it's troublesome to download those bundles here. Thx

Hello everyone. I read that V8 will become available for OEM in Q1, but is there any estimations when V8 will become available for independent engineers or maybe even NUCLEO V8 will be released?

Hi all, i search properties for manage showed multinumber counters without not cool moving.For example num 123 121 111 . Align not help here .My idea is mark textarea as number aligned and render calculate widths from font for 0-9 and use it to convert showing as monospaced . Ofcourse font editor can change this , but better is switchable choice. Exist or is this doable in an TGFX version?

We have some devices based on STM32MP257 SoCs that connect to a 100 Mbit Ethernet network via ETH1, where ETH1 is going straight to an RMII PHY. Pins for ETH2 are reserved, but are not used/not connected. Some of our devices work rock-solid as excepted, but others exhibit massive performance problems on the Ethernet connection.After lots of research, we think that our devices are affected by a silicon bug described in errata sheet ES ES0598 as "ETH1 RMII mode could have CRC errors". Our chip revisions are all rev Y, which are affected by the issue. The errata says that ETH1 should be routed through ETHSW to work around the silicon bug. To test if the workaround works for our case, I've tried to enable ETHSW, but failed so far because STM32CubeMX forces me to free some pins before it allows me to enable ETHSW in RMII mode. It seems like ETH1 and ETH3 must be used together if ETHSW is enabled, the pins for ETH3, however, are already used for other hardware functions.So,

I'm back, and working with the stm32g070rb chip. I did prototyping on a nucleo board based on the same chip (split the st link and nucleo board), and wired the ST Link to the microcontroller with the following connections I used open-ocd for flashing code to the nucleo, and it worked flawlessly. Based on the wiring, I made the assumption that this'd translate directly when developing the PCB.   (picture of the PCB and the schematic)

There is official errata named "2.5.6 Indirect write mode limited to 256 Mbytes" where indirect OSPI write requests for addr >256MB are written to invalid target address. I tested the behavior and it seems address is effectively truncated to 28bits. Contrary to what errata says, I can see the same truncated address also for indirect reads.From what I see the problem is affecting NORs only because NAND uses page addressing in 0x13/0x10 cmds and these are always smaller than 24bits.Is the assumption correct ?Martin

A minimal example of wake-on-motion detection and inertial data logging based on the LIS2DW12 3-axis accelerometer using the STM32WB5MMG as MCU host and Thomas Roell's excellent STM32WB Arduino core.

Hello,I am currently working with the STM32WBA65RI for BLE Direction Finding using connectionless mode. I would like to know if it is possible to use a low-power mode such as Standby with RTC, allowing the board to consume only a few nanoamps, then wake up periodically via the RTC, perform advertising for a defined period, and return to Standby mode.Could anyone provide guidance or share experience with this approach?Best regards.

Hello to whom this might concern,I was recently experimenting with STM32C011J4M for a small hobby project (I am trying to fit into a about coin size) and want to comunnicate with other chip over I2C. Due the size of the package I cannot use debugging to find core of the issue, so I used multimeter and legs 4 to 7 as signal outputs. I let CubeMx to generate signal configuration and try to use PA8 as output signal (overlaping with PA11[PA9]). The resulting behavior is that the physical leg 4 is stuck on 1.2V and output is not detectable. If I leave PA11 set as analog-nopull, but remove PA11 from 'HAL_SYSCFG_SetPinBinding' the output becomes readable. From rading on the other pins, I can see, that the communication doesn't work. The I2C is also on overlaping pins (default generation put the pins on PC14[leg 1] and PB6[leg8], which also overlaps with programming connections). I try to communicate with lp581

Hello, we have designed different boards with STM32G0B1.With our latest board we find that bootloader is not activated at power on, even when Boot0 is high roughly 1ms before MCU power rises (I can provide oscillogram), instead of bootloader, application is started.Of course nBOOT_SEL option is zero. After giving a reset, bootloader is correctly starting.The only difference to other boards might be MCU revision. We have that problem with MCUs marked 'Z'. With 'A' marking every board is working.Are there differences between MCU revisions regarding this?Is there a minimum time Boot0 has to be high before power on?Is reset required to activate bootloader (i.e. is it not guaranteed to start after power on? if yes, what are the differences between reset and power on, respectively where are they documented)?I did not find answers to the above in your documentation.Thank you in advance

Hello everyone,I have an NUCLEO-H755I-Q with the following setup;i) A 50Hz PWM input pulse goes to HTIM1 in PWM input mode with DMA enabled in channel 2 so the moment CCR2 has captured some data they can be transferred,ii) HRTIMCHA2 with CMP1 enabled and; Period 40000 (the timer runs at 2MHz), Preload enabled, Channel A Update resets the timer counter, Set Source the period event and Reset Source the CMP1 event.So what I basically do is simply capture a PWM, make a DMA transfer in the negative edge of the input pulse to the shadow register of the HRTIMCHA2 CMP1 and forward it as output. So, theoretically, the only delay that should be added is o

Are there any more resources to understand how to use STEVAL-HARVEST1, how does the energy flow from super capacitors to the MCU and also the back up capacitors. I feel few things are missing the schematic and the user guide. I want to first implement a small UART program with energy harvesting. Can anyone guide through steps in achieving it. How to connect this to board, does it mean I need to add any external wire from harvester solar panel and short it here?I have read
