Solved

Hello,I am working on a project with the STM32G0 series microcontroller. The MCU goes into the 'SHUTDOWN' state and wakes up when the wakeup timer times out. In the reference manual, it is mentioned that wakeup with BOR (Brown-Out Reset) is not available in SHUTDOWN mode.The manual also states that a power reset is generated when exiting from SHUTDOWN.Additionally, it is mentioned that BOR is generated when exiting from SHUTDOWN.Could you clarify which reset is actually occurring when exiting SHUTDOWN mode?

Hi,I am running TMR1 CH1 and CH1N in complementary mode (so they are the opposite of each other). Using a HAL function, how do I change each (separately) from PWM to GPIO and back to PWM? Just so to explain what I am trying to do... I am driving a H-bridge, I want to be able to:- run the PWM in complementary mode (i.e. biphase/bipolar bridge)- fix one half of the bridge to high or low while the other side still runs in PWM- switch both to either high or low- go back to full PWM complementary Thank you

I have a TextArea that spans the full width of my screen:I've selected "center" alignment:However, when I dynamically set the text at runtime,  Unicode::fromUTF8(merchant_name_data, merchant_nameBuffer, MERCHANT_NAME_SIZE); merchant_name.resizeToCurrentText(); merchant_name.invalidate();It ends up left-justified:? Thanks. 

Hi! I'm using the L6924D chip for a university, and just saw a pin called EP. Searching on net, it is pointed that it's used for thermal purposes. Is that correct? If it is, what is the best approach for optimizing this parameter, considering the module will be confined in a box, inside another box? Thank you in advance!

# OverviewI'm trying to add I2C1 in "controller mode" to an existing STM32U5G9 project, but am struggling to get it working.I am setting up the peripheral using HAL/LL calls and not relying on CubeMX setup.# What I'm SeeingThe goal is to have PG13 = SDA and PG14 = SCL with an I2C clock rate of 10kHz.  On those pins, I see no activity even though my firmware should attempt an I2C transaction after initializing the peripheral.  The two I2C pins just stay HIGH all the time.  (I have 4.7kOhm external pullups.)If I switch SCL to PB8, I do see some activity but it looks wrong (not enough clock pulses for SCL): For the ~2 clock pulses on SCL here ^, the timing is correct (~10kHz), but I'm not sure why it stops and doesn't do a full 8 clock pulses... # I2C1 Initialization Code for PG13/PG14My project is using STM32U5xx HAL `v1.5.0`.  The code snippet below is how I2C1 is initialized: LL_AHB2_GRP1_EnableClock(LL_AHB2_GRP1_PERIPH_GPIOG); LL_GPIO_InitTypeDe

I'm using an STM32 to control a DC motor with a dual hall encoder feedback.To monitor motor position I want to use a General Purpose Timer (16bits) in Encoder Mode.The configuration is going well but I notice that the logic is reversed:When the motor is going forward, the TIM Counter goes down.When the motor is going backward, the TIM Counter goes up.I could fix this issue by flipping the wires, but I would prefer just changing a HAL configuration. Using CubeMx I tried to change the count direction settings without success (the behaviour stayed the same).Is there a way to flip the timer counter logic?Your help is appreciated.

I am trying to use the KSZ8863 IC and (as shown in Table 3-9 of its datasheet) it has many configuration options behind a tweaked version of the standard MIIM interface. In particular, the opcode needs to be set to 00. I have tried the following:directly modify ETH->MACMDIOAR directly to set the PA and RDA bits as required by the KSZ8863 Table 3-9 (instead of HAL_ETH_ReadPHYRegister)set MACMDIODR to 0set the C45E bit of MACMDIOAR (I am not sure about this and if that makes sense for this PHY, but RM0433 says "When Clause 22 PHY is enabled, only Write and Read commands are valid.")Set the GOC bits of MACMDIOAR to 00 (despite it being "reserved" according to RM0433)This results in a garbage reading. I don't at present have a way to probe the MDIO physical line, so any advice about if this should be possible, and other register settings to try, would be very helpful.EDIT: forgot to mention that HAL_ETH_ReadPHYRegister works fine for reading the standard PHY registers, so the hardware c

Hello,  I am in an Internship and I got to make communicate a board using a STM32G0B1KEU6 with a PC.The pin PA12 is configured to be USB_DP and the pin PA11 is configured to be USB_DN.I don't know how to configure the others parameters and I haven't find any examples for my case.I can't use others PINs for the communication with the PC so if you have any advices or examples, I will be pleased to receive them.Thanks

Hello,I have a Yocto Project with st-stm32mp1 layer, using Poky distribution along with customized CubeMX machine that I created using st-stm32mp1-addons layersI need to use the spi5 module, so I activated it through CubeMX for the "A7NS" runtime context.I compiled and run the machine, but during boot I get this message:[ 1.533147] spi_stm32 44009000.spi: clk rate = 0               [ 1.536942] spi_stm32: probe of 44009000.spi failed with error -22  I also tried with spi1 and got the same error message.All my kernel variables are default ( SPI=y, SPI_MASTER=y, SPI_STM32=y, SPI_SPIDEV=y) I also haven't touch any clock configuration in CubeMX, everything should be default.I uploaded my boot log as attachment, you can find the error message at line 223.

I'm trying to follow the test procedure for BlueNRG-MS (SPI) indicated in the Bringing up the BlueNRG and BlueNRG-MS devices - Application note (AN4494).I am using custom board (Microchip dsPIC33F) to talk to BlueNR-M0A.SPI Setting: 625K baud rate, SPII mode 0.Following the Test procedure on Page 5, I got correct packet from BlueNRG-M0A:Step 4: I received [02,7F,00,00,00]Step 6: I received [02,7F,00,06,00]However, on Step 7, I always received [FF, FF, FF, FF, FF, FF].  Note: I sent CTRL byte 0x0B, followed by 4 dummy byte 0x00. I have checked codes again and again, have no idea where to look at.Please help with this issue, and point out a direction.Thanks.Leo

I want to design an NFC device.I plan to use ST25R3916B as the reader, as well as ST25DV64 and M24SR64 as tags.I hope it can switch between different protocols in work, including ISO15693 and ISO14443.When using the ISO15693 protocol, the communication distance is 50cm. When using the ISO14443 protocol, the communication distance is 10cmI have read other related articles in the community. Can you help me check if there are any issues with my ideas1. I plan to design two antennas to accommodate different protocols (20x20cm and 3.7x4.3cm)2. The maximum antenna I can use is 20cm x 20cm. Can I achieve my target communication distance by adding some external circuits (filters, amplifiers)? Is it possible to encounter impedance matching issues when doing so? I see that the chip of the RF power amplifier is single ended, and I think it is not suitable for use in differential signals. Their resistance is usually 50 Ω.3. Due to the fixed direction of the sensing area during use, specific antenn

Hi,I'm new to stm32g4 series and problaby have a basic question.I would like to check if it is possible to have this config:- ADC1 IN3 and IN4 as differential input (signal A)- ADC2 IN4 as single ended input (signal B)Then perform adc conversions in dual (interleaved) mode and get close to 4msps for signal A as well signal B. My concern is that IN4 is used on both peripherals, not sure if this is a problem, if I read the reference manual, it should not be a problem as long as they are not sampled at the same moment, therefore you need interleaved dual mode if I'm correct.Furthermore I would like to know if it's really possible to connect 3 peripherals to a single pin, like the PA0 pin:- COMP1_INM- COMP3_INP- ADC1_IN1If this is possible, are there any side effects that can occur?

 Is it possible to program an empty STM32F042 using UART1 instead of SWCLK-SWDIO?I want to flash programming of STM32F042 which is zero. 

Hello,Unless I'm wrong, the architecture of the TFM application as described in UM2851 seems not to allow the assignment of a peripheral (e.g. a LED pin) to the Secure context of TrustZone as it is the case with simple TrustZone applications. The UM2851 states that the user can "Replace the nonsecure TFM application example delivered in the STM32CubeU5 MCU Package by its own product nonsecure application", without raising this possibility for the secure application too.Moreover, I couldn't find on the Internet such example of customization of the Secure context of the TFM application to assign peripherals to the Secure part of the application.Is there a way to do so? If yes, how?Thanks a lot.@STea @Jocelyn RICARD @Benjamin BARATTE 

Once I enable UCPD for STM32U5G9 source mode, Cube MX (the latest version 6.12) generates code which does not compile. I am sometimes wondering what is CubeMX testing process - if it exists, ofc. 

I was using B-L072Z-LRWAN1 in a project and found out that I needed a very higher transmission rate than LoRa. I am asking if you can suggest me a board that is capable of data transfer rate of 2 Mbps with a duty cycle of 0.2ms. The data size is 30 Bytes and the distance between transmitter and receiver is around 10 meters. Can anyone suggest a suitable board?

With STM32CubeIDE on Windows 11 PC, how to setup a local (not storing on Github) version control system?How Version Control System works?  How often it freeze and save files/state of a project?  Does it restore to (a) hit 'commit' key  (b) nth compile in past (c) at any time in past?Many thanks

Hello All, I'm currently working with the STM32 H747-DISCO board, but I'm encountering some difficulties in interfacing the B-CAMS-OMV Camera Module. The LCD is functioning correctly, but the camera is not working (even though the 3 LEDs are lit). I'm running the DCMI_SnapshotMode project from STM32Cube_FW_H7_V1.11.2 (which I downloaded from the STM32CubeIDE 1.15.1 framework). After performing a clean, build all, and run, there are no errors, but I'm getting the following warning: "C:/ST/STM32CubeIDE_1.15.1/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.12.3.rel1.win32_1.0.100.202403111256/tools/bin/../lib/gcc/arm-none-eabi/12.3.1/../../../../arm-none-eabi/bin/ld.exe: warning: DCMI_SnapshotMode_CM7.elf has a LOAD segment with RWX permissions" Here's a link to my shared screen: https://www.awesomescreenshot.com/video/30135286?key=2ba1dbe8ce3ec2c1a9cdb4eaac6cd571 Can anyone help me resolve this issue?  

I am running into an issue with the STM32G0B0 MCU: Writing to PD1 seems to result in the opposite value being somehow applied to PD0, even though PD0 is set to input.Effectively, I created a new project in STM32CubeIDE, configured PD0 & PD2 as GPIO_Input (with pullup enabled) and PD1 as GPIO_Output.Next, I added the following code to the main function:  /* USER CODE BEGIN WHILE */ while (1) { /* USER CODE END WHILE */ for (int i = 0; i < 100000; ++i) { } GPIOD->BSRR = GPIO_PIN_1; for (int i = 0; i < 100000; ++i) { } GPIOD->BRR = GPIO_PIN_1; /* USER CODE BEGIN 3 */ } /* USER CODE END 3 */ Running this code on the MCU (the board is effectively empty: There are some bypass caps next to the power pins & two pullup on a couple of other, unrelated pins) results in the following output on the two pins:PD2 is DIO5, PD1 is DIO6, PD0 is DIO7.  I have reproduced this behavior on 4 different boards by now. What is going on

Hiin different posts in forum I read ST's USB library is not thread safe. There are no examples with USB CDC and FreeRTOS.Is that true?Thx 

I am using STM32CubeMonitor with the STM32H503CBT6, but I can't observe my variables. Previously, I used the STM32F1, and it still worked. 

Hello everyone,I hope you're all doing well.I'm currently working on a project with the STM32F103RET6, and I've encountered an issue when writing data to a page of Flash memory. I'm using the FLASH_ProgramHalfWord function to write half-word data. While this function works correctly about 90% of the time, occasionally it does not return FLASH_COMPLETE.To resolve the problem, I find that I need to erase the entire page. If I don't perform the page erase, the issue persists.The device operates on battery power and initializes from scratch each time it is used.Has anyone experienced a similar problem or have suggestions on how to address this issue? Any insights or advice would be greatly appreciated.Thank you!  

ST25R3916B offers two types of AAT algorithms, target amplitude and target phase. I understand that the target amplitude algorithm is used to achieve certain power level or detectable range.However, I don't understand the use cases for the target phase algorithm. What is the benefit of having a certain phase difference between the RFO and RFI? What parameter can be affected by the phase shift between the RFO and RFI. Thanks in advance.
