Hi, I'm using a STM32H7S78-DK board along with stm32cudeide 1.16.0. I'm loading the example LTDC_ColorKeyring which work fine, here is the issue... I'm trying to implement uart4 connected to the onboard ST-link. If I init MX_UART4_Init() and use HAL_UART_Transmit(), BEFORE MX_LTDC_Init(), it work fine. As soon as the LTDC is init, I cannot use the Uart at all. I don't see any pin conflict here... the uart4_tx is PD1 and is only connect to the VCP of the st-link.I'm evaluating the STM32H7S for business, but if I cannot get those two simple peripheral working together...thats a big flaw

there is nothing on  github.   there is initialization by SPI before the LTDC works is there a sequence like you initialize it first over SPI then MX_LTDC_Init() or it does not matter I do have the initialization code but I am missing something void SLGDP4571_Int(void) { SPI_WriteComm(0x20); SPI_WriteComm(0x3A); SPI_WriteData(0x70); SPI_WriteComm(0xB1); SPI_WriteData(0x10); SPI_WriteData(0x14); SPI_WriteData(0x06); SPI_WriteComm(0xB2); SPI_WriteData(0x00); SPI_WriteData(0xC8); SPI_WriteComm(0xB3); SPI_WriteData(0x11); SPI_WriteData(0xFF); SPI_WriteComm(0xB4); SPI_WriteData(0x10); SPI_WriteComm(0xB6); SPI_WriteData(0x08); SPI_WriteData(0x18); SPI_WriteData(0x02); SPI_WriteData(0x40); SPI_WriteData(0x10); SPI_WriteComm(0xB7); SPI_WriteData(0x00); SPI_WriteData(0x10); SPI_WriteData(0x01); SPI_WriteComm(0xC3); SPI_WriteData(0x04); SPI_WriteData(0x05); SPI_WriteData(0x04); SPI_WriteData(0x04); SPI_WriteData(0x01); SPI_WriteComm(0xC4); SPI_WriteData(0x22); SPI_WriteData(0

Hi there ST team! I'm asking because I'm lost in all this process.I have a QT quick app developer in QT Creator. I've already followed a tutorial from QT and I was able to flash the app in the STM32MP157F-dk2 using QT Creator.Now, I want my target board to run an embedded Linux image, and the QT quick app to run in the user space of this distro.I already installed the STM32MPU Starter package and can confirm the target runs the demo app as expected.After this, I don't know how to continue. If I understand correctly, I need to:1. install the STM32MPU developer package from https://wiki.st.com/stm32mpu/wiki/STM32MPU_Developer_Package#Checking_the_prerequisites2. follow step 7.2 "Adding Linux user space application" from: https://wiki.st.com/stm32mpu/wiki/How_to_cross-compile_with_the_Developer_Package#Adding_a_.22hello_world.22_user_space_example The problem is that step 7.2 mentions some folder that I don't know where it came fromcd <tag>/sources/<arm architecture>-<

I have a system in which the power source to the CAN transceiver interfaced to the on-chip CAN peripheral is common between multiple MCU's vis-a-vis a connector. I have experienced issues wherein if the connection is broken and then re-connected between the multiple nodes, upon reconnection I get an indefinite amount of CAN Error Interrupts firing due to Bit Dominant Errors. I perform the manual reset operation as proscribed in the reference manual (I have ABOM disabled):"If ABOM is cleared, the software must initiate the recovering sequence, by requestingbxCAN to enter and to leave initialization mode. Note: In initialization mode, bxCAN does not monitor the CANRX signal, therefore it cannot complete the recovery sequence. To recover, bxCAN must be in normal mode"However, resetting the peripheral does not reset the REC/TEC counters. To do so, I have seen a possible solution is to enter the peripheral into LOOPBACK mode and just receive frames from "myself" until the counters get low e

 Hi there,I am configuring HRTIM TIMD to generate PWM which works as expected, roughly following the Synchronous Buck Converter example for the DPOW1 eval board (my target is the nucleo64).I use LL API calls instead of HAL calls for my project.  I have configured an interrup handler to service the JEOC interrupt before calling LL_ADC_INJ_ReadConversionData12()  (? - not even sure if this is correct).  I do not see my interrupt handler being called so either:a) ADC conversion is not being triggered, or,b) ADC conversion is triggered but interrupt JEOC isn't being generated.Can someone suggest a way of ruling out one or the other problem?  For example, is there a blocking LL API call that will allow reading of completed conversions?  Is there an example of this somewhere for reference?Thanks for any help in advance. 

Hi, We have integrated the STWLC38 as receiver for our device. We want to know how to read the registers to know the status of charging, voltage and Current. https://github.com/STMicroelectronics/STWirelessCharging-C-Drivers/tree/main this gives patch update of firmware. We need configuration code as we are developing the firmware on Zephyr.

I am working with the NUCLEO-H563ZI, and I'm trying to write an application that verifies an ECDSA Certificate. I have already successfully done the verification using the  HAL_PKA_ECDSAVerif() function provided with all the parameters. My problem is that the public key that I get is in the compact form (I only have the X part and a bit to indicate which Y part to choose) so I have to calculate the Y part separately before running the verification. To get the Y part I must use the ECC curve function y = modular square root of (x^3 + a.x + b). The parameters are 192 bits long so I can't just directly calculate everything so I tried using the PKA Arithmetic function but I cannot get them to work. The function just gets stuck until timeout. With the HAL_MAX_DELAY it just stays stuck forever. Here is the code below: //Just a mockup of the actual code uint32_t number1[6] = {0x12345678, 0x9ABCDEF0, 0x13579BDF, 0x2468ACE0, 0x02468ACE, 0x13579BDF}; uint32_t number2[6]

Hello everyone,I'm trying to use the timer interrupt callback to modify the GATT characteristics and send out a notification (see code excerpt below). This only works once and after sending the message the timer no longer triggers and I no longer see any advertisements from my board. If I send the data via the USB-COM port, it works using the timer interrupt. So there seems to be something wrong with the IPCC but I don't know what it is and how I can fix it/get around it.  can someone help me ? Many Greetings,Andreas      /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_RTC_Init(); MX_USB_Device_Init(); MX_TIM16_Init(); MX_RF_Init(); /* USER CODE BEGIN 2 */ static uint8_t cnt = 0; const uint8_t max_cnt = 255; void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) { // Check which version of the timer triggered this callback if (htim == &htim16 ) { if (cnt % (max_cnt - 1) == 0) cnt = 0; uint8_t data[1]; memcpy(da

I am working on an STM32G483VET6 in my own hardware. I am trying to use TIM16 CH1 (pin PE0) to generate a PWM signal which drives a sounder. I believe that in early tests I verified that it was working but I was probably messing around manually with register values in the debugger. I therefore think that my initialisation code is wrong but I can’t see why.First of all, the pin is correctly connected; if I configure PEO as a GPIO output by setting the MODER bits for PE0 to 2 (output) and set PE0 high or low in the ODR, the output value gets to the sounder.So far TIM16 is running in PWM mode, I can see the CNT register running up to ARRand resetting but it the PE0 is tri-state when configured to be the output for TIM16_CH1.Rather than paste pages of code, these are the values in the relevant GPIOE and TIM16 registers I observe in the stopped debugger when I believe that PE0 should be driven by TIM16_CH1 but is tri-state:GPIOE registers Bits Value Comment MODER [0:1] 0x2 Alternate functi

I developed firmware with CUBE IDE and then set up the 2.4" TFT LCD screen with buttons, etc., using TOUCH GFX DESIGNER. How do I import what I developed in TOUCH GFX into CUBE IDE?

HiI have a custom pcb design with a lsm6dsv and lsm303agr. So far it is only streaming xyz coordinates.I need to come up with something like a rotating dice in this Video at minute 5:20 :https://www.youtube.com/watch?v=1mV_L-KEMy0In fact i need to Show the orientation of human head and not a dice.Which Tutorial or example project do you recommend as starting point?Is it correct that with lsm6dsv the Gyro has a good Performance, so i dont even need the magnetometer for drift correction?Is lsm6dsv the right chip, or is a better pin compatible chip in the lsm6 family?

Hi all, I'm using a L6482H on a PCB with STM32F439VIT6 to drive a stepper motor. MCU and driver are connected via SPI. I have an issue with the GetStatus command; when the switch input on the L6482H is closed and the driver receives a GetStatus command, sometimes it moves the stepper motor to order to open the switch input. It does not move the motor everytime, but sometimes it happens. I tested this behaviour by repeatedly sending the GetStatus command with the switch closed (200 ms between every command). If the MCU send a MOVE command and ask the Status continously to test the "Busy" flag, the drive sometimes moves incoerently. It seems to happen when the Status is asked with the switch closed. Is there any relation between the GetStatus and the Switch input? I configured the drive to don't use the switch as "HARD STOP" interrupt (SW_MODE = 1 in CONFIG register) and the ALARM_EN mask the external switch condition   Thank you for the support.

Hi,     Is there a way to perform a wake-up interrupt using the LSM6DSO, based around gyroscopic data instead of accelerometer data?  thanks 

Hi there STM team!I need to build a embedded Linux image for a STM32MP15 target. My application has a QT GUI already implemented. What is the best approach to create this image? I know OpenSTLinux exist but I don't fully understand what's the advantage, compared to doing everything from scrath in yocto. Thanks a lot in advance

Hi,I'm now evaluating STHS34FP80 on our original board.I've tried PMMA and BK7 glass for cover material but It seems not work well.Is there any proper material for STHS34PF80 cover?If you know the specific material name, please let me know.Thanks,

Testing Background:The current device requirements are as follows:It should operate in low-power Bluetooth mode as a BLE controller (only running the Bluetooth protocol).It should be able to run both the Zigbee and Bluetooth protocols simultaneously in low-power mode.Thus, we need to test if the Dynamic M0 firmware can run the Bluetooth protocol alone and the BLE and Zigbee protocols together in terms of functionality and power consumption requirements.Power Consumption Testing Conditions:Hardware Conditions:Nucleo development boardJP2 jumper cap removedPower Supply Conditions:Powered via JP3 and GNDFirmware Conditions:M0: stm32wb5x_BLE_Zigbee_RFD_dynamic_fw.binM4: ble_zigbee_SED_Dyn.hex Test 1:With the original ble_zigbee_SED_Dyn.hex source code: 1.1 When the development board connects successfully to both the Zigbee (Home Assistant Zigbee hub) and ST BLE app, it enters low-power mode with a current of 300-400 µA.  1.2 When connected only to the ST BLE app and not to Zi

Dear,    I want to know if running multiple algorithms like tap detection and activity recognition both can be run in LSM6DSO16IS simultaneously.Thank you.

Hello, I am developing an application using a Nucleo-H723ZG Board in Simulink. I want to read sensor data using I2C and then sending the information to an dSpace Control System using UDP. As I am most knowladgebale using Simulink Code Generation I chose this workflow for this application aswell.So far I was able to read sensor data using I2C while connected with the Board through Simulink External mode using USART3 through CN1 USB PWR. When I add the UDP Send Block to my model and try using the Monitor&Tune function in Simulink 2023a I get a XCP Timeout error and I can not connect to the Nucleo Hardware. Once I uncomment the UDP Send the model compiles and connects correctly again.I have configured the ETH using the provided tuorialhttps://de.mathworks.com/help/ecoder/stmicroelectronicsstm32f4discovery/ug/ethernet-options.htmlExternal Mode is configured to use serial interface. Does anyone have an idea where this sudden behaviour change my come from?Best RegardsMartin

I need to purchase a development/evaluation board to perform my development activity. We had finalised to use STM32F765VGT mcu and i need a compatible eval board for that as i don't want too much hazzel to port code to targetted MCU.I found this eval board, stm32f779i-eval. Is this compatible and requires less effort for porting or changing the mcu in the cubemx. Need support on this. Regards,Aashik

 Downloading a selected version of STM32CubeMX does not work.Download link:https://www.st.com/en/development-tools/stm32cubemx.htmlWhen I select 6.11.1, and login, nothing happens.I can downlad the latest version 6.12.0.Am I doing it wrong? 

I am currently working on using the USB3320 ULPI PHY with the STM32H7B0VBT6. After reading the STM32 reference manual, I noticed that it mentions special attention should be paid to the hold time when operating at 1.8V.Additionally, I came across a forum post discussing how to select a ULPI PHY:https://community.st.com/t5/stm32-mcus/how-to-check-compatibility-on-usb-ulpi-transceivers-with-stm32/ta-p/657275However, I found that the tDC/tDD for the STM32H7B0 at 1.8V is as high as 13ns, and 1s/60Mhz = 16.67ns, 16.67ns - 13ns = 3.67ns. I have not been able to find any PHY that meets this condition. For example, the setup time for the USB3320 (used on EVAL and Discovery boards, In ULPI Output Clock Mode) is 5ns, and most PHYs I have found seem to have a setup time of over 5ns, which clearly does not meet the ULPI timing requirements. Is there any PHY available that can be used with the STM32H7B0 at 1.8V VDD and also meets the timing requirements?  Thank you in advance for you

Posted on November 05, 2012 at 11:29Hello, I designed a board which contains stm32f105 microcontroller, and i want to use DFU as bootloader in order to download my program to the micro controller through usb port. I put BOOT0 =1, and BOOT1=0 PA10=PD6=PB5=0 then i powered the circuit and connected it to usb port of my pc which runs windows xp. But the pc didn't recognise a new device. These are the processor data: STM32F105 VCT6        Z 990TD   93 MYS 99 045 First question: Why the pc didn't recognize a new device? Second question: the date code is 045 what year does this mean?
