Sorry to bother you.I don't need the HDMI chip(sii9022) in my project. So, I first removed the HDMI chip on the STM32P157F-DK2. In fact, I manually removed it with a soldering iron. My SDK and development environment are based on "stm32mp1-openstlinux-6.1-yocto- mickledore-mp1-v23.06.21" "en.SDK-x86_64-stm32mp1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21.tar.gz".At first I didn't make any modification, the mipi display screen will not work normally after the kernel boots, after some fumbling, I modified the device tree and now the mipi screen displays normally, my modification points are as follows(filename:stm32mp15xx-dkx.dtsi):hdmi-transmitter@39 { compatible = "sil,sii9022"; reg = <0x39>; iovcc-supply = <&v3v3_hdmi>; cvcc12-supply = <&v1v2_hdmi>; reset-gpios = <&gpioa 10 GPIO_ACTIVE_LOW>; interrupts = <1 IRQ_TYPE_EDGE_FALLING>; interrupt-parent = <&gpiog>; #sound-dai-cells = <0>; status = "disabled"; p

Hi, it's not clear the deliverable power of the ST25R3916B. it seems 1.6W in balance output configuration. On the datasheet is written only that there is a dynamic power output, on the first page then no more other information, and there are no registers about the output power it seems..I have to do a connection P2P between 2 eval NUCLEO-NFC08A1, but i get only 9cm of maximum distance range. it's a poor result for 1.6W...is there the possibility to control manually the power output?how is it possible to increse the distance range in P2P mode (without changing the antenna)?i'm waiting your reply soonthanksLogantenna

I have an RS585 1/2 duplex transceiver hooked to USART2 configured for hardware flow control (RS485) on an STM32L412 micro.Is it possible to program a virgin part using the STM32CubeProgrammer, and to later do a firmware update over this comm channel?I searched the forums but did not find a definitive answer.

I'm on Nucleo-F303RE board, which according to the page 129-130 of the reference manual (RM0316 Rev 10) I should be able to set "TIMx (x = 1/2/3/4/8/15/16/17/20) can be clocked from the PLL running at 144 MHz when the system clock source is the PLL and AHB or APB2 subsystem clocks are not divided by more than 2 cumulatively": However, when I create a new project for Nucleo-F303RE board, and configure the clock tree to meet these conditions (system clock source is the PLL && AHB or APB2 subsystem clocks are not divided by more than 2 cumulatively), then I can't seem to toggle the dot in the muxes for TIMx source mux (where x=1, 8, 15, 16, 17, 2, 3/4), and the dots in the muxes are greyed out int he clock configuration tool:I'm new to STM32 environment, so I might be doing something basic wrong.

Hi,I need help configuring a USART connection between a STM32L452RE Nucleo Board and a ESP8266-01 wifi chip. My goal is to send AT Commands from the STM32 to the ESP8266.I currently have my USART TX and RX connected to the RX and TX respectively of my ESP8266 board, and I've noticed that the LED is flashing on the ESP8266 when debugging through these commands, indicating that a signal is indeed being sent via my USART. However, i've noticed that the data has been scrambled on send and receive, as if i change the password to my wifi hotspot, I am unable to connect to it. By piping the USART1 RX directly to my serial monitor, I noticed a significant amount of scrambling.I have proved that this sequence of commands works as intended, and have been able to connect my ESP8266 to an arduino uno, as well as an STM32 bluepill using RX and TX in default mode, but my attempts to get my project to work on the STM32L452RE have failed.The way that I am piping the commands is shown above, and the ou

According to the STM32H7's datasheet, the M4 core shouldn't be able to boot from an SDRAM memory address (because it's outside of the range 0x00000000 to 0x3FFF0000):However, I found out that I can actually boot the M4 core from SDRAM, if I used the alias address at 0x70000000 (which is also outside of the range) instead of 0xC0000000. So I'm wondering if this is a documentation error, or an undocumented feature/bug that we shouldn't count on ? Thanks!

Hello everyone,I have a question about the STM32C011J4M6 in S08N package.I am developping a PCB with this MCU and want to use an LSE like in the picture below.Then I also want to program and debug my MCU with an stlinkv3 and will use the SWD debug so the 2 wire SWCLK and SWDIO will be connected to PA13 and PA14.The problem is that in the pinout view below, PA14 and OSCX_OUT are on the same pin.So can I connect to pin 8 at the same time a quartz and a trace for SWCLK ? 

Hello everyone, I need help .I noticed a very interesting problem, which is this.I use STM32F429I-DISCO1 when I activated I2S_2 in the master mode PORTB_13 pin = CLK , but in reality it was always = HIGH level , after that I deactivated I2S_2 and configured it as an output pin , speed= very_high . Also no reaction, when checked with a tester that pin again everything is fine, the pin is brought out , then I looked at the board schematic, it turns out that this pin is connected to the USB OTG as VBUS_FS, I also disabled the USB_OTG function, it didn’t help either. On the other hand, I think if it’s not possible to use this pin, why in CubeMX is this pin not disabled? Thanks in advance.

Hi,I am switching PB12 on/off with 1 second delay on STM32F030C8T6. Measuring with the multimeter, the HIGH state is only 0.2 volts, even though Vdd is 3.3V. I have turned off all things that could be drawing too much power from the MCU. Other pins output a voltage very near 3.3V. There are no external connections with PB12, only a 10k pull-up resistor. What could be causing this?

I am developing a custom bootloader for a client on an STM32 system. I am using STM32CubeProgrammer to exercise the new bootloader and the built-in system bootloader to investigate the protocol being used over UART. In addition, I am referring to AN 3155, which describes the protocol.The issue/confusion I am facing is that when using the system bootloader and STM32CubeProgrammer and capturing the UART traffic for erasure of a single page, I see a different message sent from the programmer than that described in AN 3155, unless I am missing some important detail in the app note.For example, erasing the first page of an STM32F103 I capture the following output from STM32CubeProgrammer.:[43h] [BCh] [01h] [00h] [2Bh] [2Ah] The first difference to the app note is in byte #3, the number of pages to erase. According to AN 3155 this should be N-1, so I would expect this to be "00h."Secondly, byte #5 appears to be undocumented, the list of pages, in this case just page zero, should be foll

Hey all,It is a very basic question and I would appreciate some help on this. I am working with M24LR-Discovery Tool kit  and I want to detect my own tag with the RF Transceiver. I downloaded the  Software source code STSW-95HF002. and understood whats happening in it. Now, I edited the code as per my requirements and want to build it. I imported the Files in STM32CUME IDE (the downloaded source code does  not come with ".project"  file) and want to build the project and again program the controller. How can I do it? I am not able to find the appropriate build configuration for the project. I imported the project as File -> Import -> General -> Projects from Folder and ArchiveHow can I do the same for TrueStudio? Just some small backgrounfd: The tool kit comes with a MB1054B-CR95HF Transceiver which has a STM32F103C8T6 controller onboard and I just have to program that. Thanks in advance :)

Is there a way to use __HAL_TIM_SetCompare() for negated signals while generating complementary PWM signals?Any help would be appreciated 

Hello,I want to build a simple application (like a UART message, GPIO bit-bang etc.) targeting SR6G7 and running on a custom board. To support that I want to use the latest SDK 3.3.0 and flash the code via StellarLINK.Is there any guide how to add the SDK resource to the StellarStudio?Thanks in advance!

Hi,I have doubt with the spi communication setup in this configuration. I'm using two sensors where one of the sensor only support 3 wire spi and another  is 4 wire .I have a single spi in mcu. The hardware setup is followed by mapping four wire spi to mcu(mcu is configured in full duplex mode) and put a resistor between miso and mosi and given to three wire spi slave. >Is it possible to make proper communication in this setup?>If this is okay how the master mcu will differentiate betweeen them?

Hi, I'm trying to design hifi amplifier using TDA7292 refering its datasheet.I read the datasheet of TDA7292, and I have some following questions :​How can I use differential audio input at TDA7292? Is it okay to connect amplifier's IN1- and IN2- pin to differential audio source's L- and R- pin instead of connecting those amp pins to GND?With a single supply circuit, is it okay to supply single +48V 2A power to TDA7292? In TDA7292's electrical absolute maximum ratings, it the maximum DC supply voltage of TDA7292 is +-35V. But what I'm trying to design is single supply circuit. I wonder if it would be overloaded.Is there are any disadvantage using 'For Single supply' circuit instead of using 'For Dual rail supply' circuit?I found what I assume to be an error in the Figure22 diagram on page 17 in the datasheet. Pin 2 of the TDA7292 is OUT1 and pin 10 is IN1-, but in Figure 22 they are reversed. It seems to me that this is an error, am I right?​I'm newbie in circuit design, so please unde

Hi,I'm using a STM32WB55RG Nucleo and STM32WB55 USB Dongle. I programmed the nucleo as FTD and write 2 sources and programmed the usb as MTD and write 2 sources that exactly the same with FTD. I'm trying to send coap messages from FTD to MTD so this is my message flow Nucleo(as leader)  --> USB (as end device). As I said I write my sources properly and test my code as both of them(Nucleo and USB) are FTD. It works but when I programmed the USB dongle as MTD, the usb dongle does not get the coap messages. I'm sending my messages as Multicast from FTD. How can I solve this problem?Best regards.

Hi all, I'm trying to get some accurate orientation data from the accelerometer and gyroscopic capabilities of the LSM6DSV16X, but am getting some different data from different GUI software. The Unicleo-GUI paired with the STEVAL-MKBOXPRO (SensorTile.box PRO) when programmed through the Algo-Builder will give a gravity vector reading and Euler Angle readings which are susceptible to linear acceleration (something independent of 3D orientation). The Sensor Fusion display would also move in response to linear acceleration on a plane even though there was no change in orientation. The Unico-GUI on the other hand, when paired with the STEVAL-MK1109V3 board mounted with the STEVAL-MKI227KA (carrying the LSM6DSV16X), did not present the same unwanted response to linear acceleration and provided a clear and clean independent representation with little irregularities in the Sensor Fusion visualization either. What might be the cause of the difference between the two GUIs since it appears

I am developing a device using stm32f429zit6. I want to know the usage rate of all software functions in the project, how to use the SWV statistical profiling menu in stm32cubeide? After setting Debug (Trace Asynchronous Sw), debugger menu, and serial wire view in the System Core settings menu, I pressed F8 in SWV statistical profiling to operate the device, but no function profiling output occurred.  

Hey guys,Recently I was reading code from X-CUBE-MCSDK and was amazed at the well organised style. So I was just wondering if there is a full code specification or document for me, which would be of great importance.Apologies for my poor English and thanks for helping!

I have image of an IC and I am not able to identify what is the component and part number  Please support.

As shematic below the pin7 is connected to GND so there will be a 60uA leakage .so how to disable the internal pull up by config the register.    

I'm using a STM32F105 and can program the firmware with an ST-Link to get firmware with USB DFU device driver on the device.The device gets recognised if I connect it with USB and I can connect and read the memory without issues.If I try to program a new firmware over USB it all looks good but after the verify step I get an error: Download verification failed.When I check the firmware is not updated at all. It's weird because in the log I see that the sectors get ereased and download is complete but it seems nothing is written to the flash.See print screen below.
