Hello, I am a university student and I am trying to design a development board with the STM32H7S3A8I6. In the past, I've just used the power scheme in the documentation of the MCU for reference, but the power scheme in the documentation (page 153) for this MCU is incomplete (I'm assuming its becasue it's new). I used this "Getting started" guide for the STM32H7A3 and made a few assumptions from past STM32 designs that have worked, but since I cant find any good references or documentation on the matter, I am not confident in my work. Has anyone used this processor before or know where I can find good reference designs to cross check my work? Ive attached my schematic below. I am trying my best to learn best PCB design practices so if there is anything else I can improve on please let me know! Edit ST moderator: moved to the right Destination and added the right labels

Hi, Team   We are facing issues with test process performed at ICT test station. We are testing driving current to detect Zener Clamp diode 8.2V, the units fail with 2.64688 volts, but this line is connected to comparator TS339I pin 5 that is not power up. When disconnect the pint 5 of this comparator, TS339I, our Zener Diode start works and the voltage 8.2V is present.     Our concern is related with this TS339I that something is affecting Zener's test process when the V+/V- of the comparator are absent, probably the current used for the test, partially is going into the comparator. Do you have information about this behavior and recommendations when this device is tested? Or are there some test recommendations or critical aspects that need to be careful when is under test for these comparators?

Hai, First let me be clear I'm working on STM32F746ZGT7 customized board so I have to bring up the Display of the board now give me some reference video or documentation.   Thanks.

Hi I want to understand "which register decides whether HSI or HSE oscillator is selected for PLL clock source in STM32F407"(selection of the HSI or HSE oscillator as PLL clock source"B.RAsh

Dear All,I would like to interface an ADC (ADS131M08) with a STM32F407. The ADC datasheet mentions that for better performance, the ADC clock should be synchronized with the SPI clock. Is there any way to achieve such synchronization with the STM? I was thinking about a timer that can give the clock to the ADC and get this timer sync with the SPI, but I don't really see if it's possible and how to implement it.Thanks for your helpBest regards

Hello,I need clarification about the STM32WBA50KG Tx Output power for BLE 5.4.It seems that there's an inconsistency in the value of the Tx Power.This page STM32WBA50 overview  mentions +10dBm.But the datasheet STM32WBA50KG datasheet  mentions +4 dBm (page 62). What is the correct information ?

Hello ST, 1. ds12736 Rev.4 states in Table 24 that the abs. max. voltage on any pin is at least +4.0V (but this may be further limited by an injection current limitation) 2. ds12736 Rev.4 states in Note 4 on p.145: "Positive injection (when VIN > VDDIOx) is not possible on these I/Os and does not occur for input voltages lower than the specified maximum value." 3. ds12736 Rev.4 states in Table 25 that I_inj(pin) is specified as -5/+0 mA on all pins. 4. AN4899 Rev.3 says on p.13: "Positive-injection current is the current induced when VIN > VDD." and "0 mA means that current injection can damage the GPIO and induce STM32 malfunction."   These statements taken together seem to be contradictory. So the question: May STM32L562 GPIO pins be driven in a range from 0 V to 3.3V when VDD and/or VDDIO is unpowered or below 3.3V? The datasheet seems to imply "Yes", but AN4899 seems to indicate the opposite in the context of the specified I_inj(pin).

Hello, this is DK.I am working on a project using stm32f429IIt6.I'm currently having an I2C problem at the end of my project.I2C1 uses PF 0, 1 / I2C2 uses PB 6, 7. The HW PCB completed, and the HW I2C pull up is the same.In I2C1 HAL code, the entire initialization does not work, and if I2C2 is used with the same code, it works well.I am using various Pheripherals such as TIM Interrupt. Is there any conflict?Is there any difference between I2C1 and I2C2?In the TIMER part, it appears to share APB1. 

Hello Community!Recently i have started working on USB MSC using RTOS. Im using USB HOST Library version 3.5.2 and latest version of CubeMx.When im generating the code by selecting FreeRTOS CMSIS V2 and pulging my USB drive to CN13 connector then the Appli_state is always staying at APPLICATION_START state and not not going to APPLICATION_READY state.but on other hand if im selecting FreeRTOS CMSIS V1 instead of V2 with keeping same configuration then USB Appli_state is changing imidiatly to APPLICATION_READY state when USB is getting connected to CN13 connetor.Here im using STM32F746 NUCLEO board. if anyone knows what is the issue please reply.Thank you! 

Hi I am using STM32F407 I want to make IRQ handler for busOff inetrrupt so can I use CAN1_SCE for bus OFF interrupt? B.R Ash

My hardware has the I2C pins (SDA and SCL) connected incorrectly, and I cannot change them because the hardware is already built. Is there any way I can fix this issue from the firmware side? Can I change the pins through software? hear attach my schematic photo . atck pin are incorrect and i can  not change it. please help me .   

For product A (68-pin VFQFN package), pins 31 and 66 are VCAP pins, and 2.2uF capacitors have been placed on each pin. Should pins 33 and 66 be connected to each other, or is it sufficient to place the capacitors on each pin individually?

Hello,I'm using the X-NUCLEO-NFC03A1 dev kit with the CR95HF RFID chip. The protocol to talk to the chip I'm using is SPI, and the ISO configured is 15693. I can confirm SPI comms are working as both the ID and ECHO commands work. I also seem to get the correct response from the chip with the protocol is selected and configured for 15693. Unfortunately it seems like RFID tags are not getting detected. I can confirm the RFID tags are programmed and work as expected as I can used my phone's RFID scanner to detect the tag, and the protocol is detected to be 15693. I've attached a Saleae capture of the SPI comms between the MCU and the CR95HF when using a Send/Receive command. The error code that is returned by the CR95HF is 0x87, which corresponds to not detecting an RFID tag.Currently I'm using the default 15693 protocol config of 0x00, but have tried lowering the protocol bit rate and waiting for SOF.Help would be greatly appreciated! Capture of configuring the

Hi all.I would like to use the VN5T016AH-E high-side driver and I have some questions.*Are there 8V in the CS pin under fault conditions?*Can it measure max 4.2A with a K about 4240? Why do you specify 4V in the datasheet without knowing the value of the Rsense resistor?*If I don't need latch-off option, is there an autorestart mode after a fault condition?Many thanks.

I am currently choosing an LSE and HSE crystal for an STM32H743 project. AN2867 includes tables of compatible STM32 crystals. There is also a crystal selection tool from ECS which i've used. My question is, after selecting a crystal from the tables, is there still a need to perform any of the steps outlined in section "4.2: How to select an STM32-compatible crystal"? Is it enough to simply select a crystal from the table, follow the board layout guidelines, and check the crystal frequency with an oscilloscope? Thank you.

Hello ST Community, I’m working on a project that requires both Bluetooth Low Energy (BLE) and CAN connectivity. Ideally, I’d like a single MCU solution from ST that includes both a BLE radio and CAN (controller and transceiver, if possible). Single-Chip Option? Does ST offer any MCU that integrates BLE and CAN on one chip? I’ve looked into the STM32WB series for BLE, but it doesn’t appear to include CAN. Is there another family that might have both? External Module Choice If there’s no single-chip solution, which approach would you recommend? Use an STM32WB for BLE and add an external CAN transceiver? Use an STM32 MCU with CAN and add an external BLE module? In terms of complexity, power consumption, and development effort, which route do you find more straightforward? SPC5 Series I’m also curious about the SPC5 line, which seems dedicated to automotive applications. Is it a good option for integrating CAN + BLE (externally for BLE, perhaps)? Or is it overly specialized

I've setup a custom USB device with multiple interfaces on custom hardware using a ULPI. The USB code is derived from the code generated by CubeMX.On interface 0 I have endpoint 1 in and outOn interface 1 I have endpoint 2 in and outOn interface 2 I have endpoint 3 in and outFrom the PC, I wrote a very simple program that can send and receive a single packet. I can send and receive data  on interface 0 (ep1). I can also send data from PC to device to on interface 1 (ep2), but I cannot receive data. Interface 2 has not yet been implemented. Transmit and receive buffers are set as follows in usbd_conf.c: HAL_PCDEx_SetRxFiFo(&hpcd_USB_OTG_HS, 0x200);HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_HS, 0, 0x20);HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_HS, 1, 0x80);HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_HS, 2, 0x80);HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_HS, 3, 0x80); In my custom device class I open all three pairs of EP's exactly the same way. I'm missing something though. My presumpti

In my application, I have a watchdog timer that resets every 45 seconds if not fed. I also have an RTC. The application records sensor samples, along with timestamps from the RTC.Problem is, when there is a watchdog reset, the RTC is re-initialized to default date and time. This messes up the sample/timestamp collection.Are the RTC time/date values still maintained even when there is a watchdog reset? Would it make sense to skip setting the default date/time when a watchdog reset has been detected?Thanks.

Hi,I am currently working on a Bluetooth application using the STM32WB5MMG module.I want to configure the RTC such that it generates a WakeUp interrupt every 5ms to read sensors and do some computation before going to stop mode for the remainder of the 5ms interval.For the Bluetooth stack to work I had to activate the RTC, so I guess the Bluetooth stack somehow interacts with the RTC.The RTC wake-Up interrupt itself is not needed for Bluetooth, so my naive understanding is that activating and configuring this interrupt does not have any side-effects on Bluetooth and vice versa.Yet, when I configure the RTC WakeUp as shown in the screenshots at the end of the post and add the call shown below to my initialization code in the main method, the intterupt is triggered exactly once and not periodically.HAL_RTCEx_SetWakeUpTimer_IT(&hrtc, 82, RTC_WAKEUPCLOCK_RTCCLK_DIV2);Now, if I take a look at the interrupt callback in stm32wbxx_it.c, this looks as follows:void RTC_WKUP_IRQHandler(v

Hi, I’m working with an STM32G0 MCU and utilizing the USBPD and USB_DEVICE Middleware packages.In my application, I need to detect if the connected device is running iOS. Since all Apple devices have the Vendor ID (VID) set to 0x5AC, I plan to use this as a distinguishing factor. However, I’m unable to locate where and how to retrieve this VID within the STM32 software framework. Is there a specific function or method available in the Middleware or USB stack that allows me to access the VID of a connected device? If not, could you guide me on where to look or how to implement this functionality?Thank you!
