Hello STM32-Team,do i have to use the MLPF-WB55-02E3 or MLPF-WB55-01E3 matching network for UFBGA129. In the Appnote AN5165 (Table 6) the matching network MLPF-WB55-01E3 matching network is recommended, but in the Datasheet of the MLPF-WB55-01E3 its only for the STM32WB55Cx/Rx. In the MLPF-WB55-02E3 datasheet its for the STM32WB55Vx and the UFBGA129 would be the STM32WB55Vx.So im a bit confused whats the right choice for the UFBGA129.Thanks an Greetings,Matthias

Respected Sir/Mam , I cannot able use the keyboard example in the ongoing project of the same screen in STM32H7B3I-EVAL.When I have tried to insert it, it is not visible and having blank code inside it. Although Touch GFX 4.17 version has that facility. 

I am using Nucleo-L476 board and NFC06A1.With the Free RTOS sample (ST25NFC_Embedded_Lib_ST25R3916_1.4.0, FreeRTOS_polling), I am aleady verified the NFC card operation with the SPI interface.I tried to check the operation with I2C instead of SPI, but it did not work, so please inquire.* Apply UM2616 documnet 3.5.1 item 1) H/W setup • solder ST2 and ST4 jumpers • solder R116 and R117 pull-up resistors • remove the SPI solder bridge(R205) • put the I²C solder bridge(R204) 2) S/W setup • set RFAL_USE_I2C in the pre-processor • rename USE_HAL_SPI_REGISTER_CALLBACKS by USE_HAL_I2C_REGISTER_CALLBACKS* Status Within the "st25r3916Initialize" function, it proceeds only to the "st25r3916ExecuteCommand( ST25R3916_CMD_SET_DEFAULT )", and does not proceed any further.Inside the "BSP_I2C1_SequencialSend" function, the "hi2c->State" value does not change to HAL_I2C_STATE_READY.To use I2C interface, is there anything else to add other than 3.5.1 items of the UM2616 article?

Hello guys,First of all I want to say that I don't like and don't use HAL library. Use LL_Library instead as long as possible.Now what brings me here is that currently I am manually porting FreeRTOS to an STM32469NI MCU. This force me to use a different time base other than the Systick. I have realized that when using another timebase source ( example TIM1), STM32Cube MX autogenerated code always includes and initialize the HAL library in mainMy question: is there a workaround to get rid of the HAL library in this case and work exclusively with LL?Any help or suggestion would be greatly appreciated

Hi All,I have a STM32H7 master communicating with I2C to 4 STM32F0 slaves. The I2C uses DMA but intermittently stalls when the master is transmitting to a slave. It sends the address and the first data byte successfully (acknowledged), but then fails to transmit the second data byte and the clock is held low. No errors are returned, but the driver waits indefinitely for the transmission to complete (which it never does). There is a screenshot of the bus stalling attached.Note, the I2C buffers have been located in non-cached memory and is accessible by DMA.Is anyone aware of any issues with transmitting I2C using DMA?Kind RegardsDavid

In UM1718, it states that IPCC is only used for the STM32MP1 series.I understand that I need to update the version that I'm using however, I do not want to loose and have to restart again for our project. Furthermore, I've tried to use the H747 and other dual core MCU's but, only the series MP1 indicates the IPCC.I need to communicate and share data from CM7-CM4 and visa versa.is there a way to setup IPCC in Cube MX 6.3 or do I need to use STM32 Cube H?If I can use the current version I have, how do I establish a communication link between cores in Cube MX? Please recommend the documentation that I would need. AHB, Simplex Communication I've studied but, I have not solidified the setup.Thanks,Hiram

I noticed a problem with STM32CubeIDE 1.10.1:When build, a second time, the same files as before get compiled again.All my projects were migrated from 1.9.Steps to reproduce:Modify a fileRun the build, it compiles that fileRun the build, it compiles that file againRun the build, it finally does not compile that fileThank you

I want to enable the RTOS Proxy in the debug launch configuration for my STM32CubeIDE project. However, in the "Driver settings" fieldset, I need to select a "Port" from a dropdown. The options in that dropdown confuse me. I have an STM32WB55, which to my knowledge is considered an MCU, not MPU, and it consists of an ARM Cortex M0 + ARM Cortex M4. My application is running on the M4, since M0 is dedicated to BLE.The 3 dropdown options for M0/M4 are 1) "ARM_CM0", 2) "ARM_CM4F" and 3) "ARM_CM4_MPU" - but my code runs on M4, so 1) is probably not right, I don't use the STM32F-Series, so 2) is probably not right, and the WB55 is not an MPU, so 3) is probably not right either. I am certain that my naive interpretation of those cryptic port abbreviations is wrong for at least one of the options.So - what is the right selection to make?

Hello,I am trying to get information from two analog sensore (FSRs) by using two seperated data lines (PB0 as IN15 and PA7 as IN12) through ADC1(Not important note - I created unint32s for debuging and I am willing to transfer the data by using CANBUS as you can see in the main.c)The problem:I am getting the information from the sensors, but the data of one sensor gets corrupted by the other one. For example if I pinch the left FSR his data chanegs from 10 to 4095 but if I pinch the right sensor, the left sensor data still changes but from 10 to 800. The exact same thing happans both sides. What could be the problem? How can I make the data line seperated from eachothers?I am attaching the main.c and the configurations.In addition its on Circular Mode, Increment address is only Memory and with Data Width of a Word Thank you,Raam Kavod

Hello everyone,I am using an STM32H723ZG MCU and wanted to use ADC scan conversion with DMA. I could implement what I wanted there is just one thing I do not fully understand related to it.I am using ADC3 whose maximal resolution is 12 bit. Based on the reference manual of the MCU, the data of the ADC conversion is stored in a 16 bit register. When I configure the DMA, I have to choose Word as the data width. Word means 32 bit here.My question is: Why? Why do I have to set the data width of the DMA 32 bit if the result of the ADC conversion is stored in a 16 bit register?Thanks in advance,GVG

Hi all,I'm trying to write in the internal flash memory of my new MCU (STM32L496VGYXP),but FLASH_WaitLastOperation fails. The error seems to be FLASH_SR_PGSERR .I'm sure that my code used to write flash memory is correct because in others projects it works perfectly.In the others projects I used the following MCU:STM32L496RGTXSTM32L452RETXSTM32L432KCUXSTM32L496ZGTXCan this problem related with the new MCU?What could I try to do in order to fix it?Thanks in advance--Mario

I'm using a NUCLEO-F429ZI. It can't go to UART bootloader when using the reset button (BOOT0 connected to 3.3V). It will only go to UART bootloader if I power cycle the board ((BOOT0 connected to 3.3V)). What is going on? It should read the BOOT0 pin after reset and then wait for 0x7f on UART1.I have broken off the st link and also disconnected the bridges to ethernet. I also have the similar problem to enter SPI bootloader.

In other words, what is the relation between F_RS (and possibly F_PCM) and mdf_ker_clk in DFLT? I use every block in DFLT: ADC1 -> DFLT (CIC, offset, scale, RSFLT, HPF, INT) The reference manual mentions only the RSFLT block with up to 24 ticks, but my estimate for the whole chain is around 62 ticks.

Just installed the new version 2.11.0. Never used any version of CubeProgrammer before. I am using it on Windows 10 with Java 18.0.1.1.2022-04-22. When I start it, just the start-dialog appears and disappears after some seconds. In varioius posts I have seen that this happens since years. Hints to re-install Java or use another version didn't seem to work. As the programmer is distributed with an jre, I tried to set path to its bin-directory and JAVA_HOME to the jre path, but this didn't change anything and calling java.exe from the programmer-directory just leads to a java-error message. Any hint how to get it running?

To me, it looks like each gain step shifts by "half" a bit, so we could compute the gain asfloor((DSfilt - DScic)*2);e.g. with RSFLT as target and Sinc5/Dec5 + 14bit ADC1:floor((22 - 25.6)*2) = -7;

If you have the link to the video recording of this seminar, please share it. Thanks you! (I could not access the online seminar and would like to watch the video.)

When I try to debug the standard led toggle example I get the No ST-LINK detected message,Board: STM32H7A3ZIT6QHost: Windows 11IDE: STM32CubeIDE 1.10.1When I open Device Manager and connect the board to USB there is not one extra device detected. I also tried to add the device drivers manually by using the Device Manager and opening STM32CubeIDE\drivers\STLinkUSBDriver.

HiJust updated in my PC STMCubeMx and STMCubeIDE for last version, and at this moment the functionality "Ctrl + Click" on a pin to see possible alternate pins is no longer working.This started to happen after updating CubeMX to v6.1.1 (previous version I think was 6.0) and it was working. In CubeIDE after last update also stopped working, well it is using the same version v6.1.1 of CubeMx...Also tested in my Work PC, and same issue after updating from v6.0 to v6.1.1 the alternate pins no longer show.Is this a Bug? Or could it be some other thing...Thank You
