Interface and connectivity ICs

hello community,I´m using PB10/PB11 as I2C1 and PB6/PB7 as I2C2.I2C1 works correctly.But I2C2 not, after reset on PB6 and PB7 I just get some messy signals as below, It seems the I2C2 is not initialized with succcess.Actually the both I2C are initialized in the same way:Here is the pin definition for both I2C//sensor1#define BSP_I2C                                   I2C1#define BSP_I2C_CLK_ENABLE()                      LL_APB1_EnableClock(LL_APB1_PERIPH_I2C1)#define BSP_I2C_CLK_DISABLE()                     LL_APB1_DisableClock(LL_APB1_PERIPH_I2C1)#define BSP_I2C_DATA_PIN                          LL_GPIO_PIN_10#define BSP_I2C_DATA_GPIO_PORT                    GPIOB#define BSP_I2C_DATA_G

1.Is there a Demo board for STOTG04? If so where can I procure it?2.It is given in the datasheet that STOTG04 supports OTG so how Vbus is being switched during host and device?

Hi,I ask for the following issue.I am testing the STEVAL-IDB008V1 board, the BLE RemoteControl example.I am able to compile the original WiseStudio example project in WiseStudio IDE. THE PROBLEMI imported the same project from WARM project  in TrueStudio Atollic (9.3 version) according to the importing instruction: I am able to compile the original project files but in the linking phase an error is detected with the libluuemrg1_stack.a library.Some symbols (related to the the cryptography functions AES......) are not found: a message like"undefined AES..... isn't used" appears and the link operation (by using arm-atollic-eabi-gcc -o command) finishes without the executable file.Do you have any suggestion?Thanks in advance.Mario

Hello, i used the CubeMX to generate the example code for the X-Nucleo-BNRG2A1 board. The Example works well when the #define USE_BUTTON (0) :  However, when #define USE_BUTTON (1) I get the following blank page:  I've had the same behavior before updating the Firmware of the Module and after.   Thank youAmir    

Hi,How do you re-program the NVM on STUSB1600? The current datasheet (DS11503 - Rev 4) refers to Chapter 6 that doesn't give any information.Best regardsNiclas

Hi,We are looking for a Bluetooth module that support Classic audio in Hands Free Profile Audio Gateway (HFP_AG). We are looking for EVK with an example of HFP_AGThanks

I have STEVAL-CCC002V1 with STUSB1600A controled with STM32F103 over I2C. Samsung Galaxy Tab connected to USB-C and I want to charge it.But I can't switch to "source power role". No matter how hard I try the controller is still in sink.Here I have a list of several I2C registers:CC_CAPABILITY_CTRL @18h: 10100001- 3.0 A USB Type-C current- VCONN discharge disabled on CC pin- VCONN supply capability enabled on CC pinCC_POWER_MODE_CTRL @28h: 0VCONN_MONITORING_CTRL @20h: 10110000MONITORING_STATUS @10h: 1011- VBUS, VCONN - OKVBUS_MONITORING_CTRL @2Eh: 111CC_CONNECTION_STATUS register @0Eh: 1000001- CC_ATTACHED_MODE: source attached- DEVICE_POWER_MODE :operating in normal power mode- CC_POWER_ROLE: operating as a sink- CC_VCONN_SUPPLY: VCONN is not supplied on CC pin- CC_ATTACH: attachedCC_OPERATION_STATUS register@11h: 10000010- CC_PIN_ATTACHED: CC2 is attached- SINK_POWER_STATE: PowerDefault.SNK (source supplies default USB current)- TYPEC_FSM_STATE: Attached.SNK Anyone have any idea

Mode 2 Can read and write sensor data directly through the psi5 operation register?

I'm searching for detailed information on the Serial Peripheral Interface (SPI) protocol used by the ST33TPHF20SPI component, including register details and specific IDs that need to be read or configured.

Can Mode 2 of the L9663 read the sensor data directly with the MCU? Or do we go through SPI?

I am using the blue-nrg-lps,but when i test the hid example project , it cannot work in win11,but it is ok in phone and pad,so anyone can tell me why? A new player of ble-nrg-lps...

DK version:BlueNRG-LP DK 1.1.0chip:BlueNRG-345AC​2 problems of the ble hid keyboard project. ​1st, if BlueNRG-LP is not conneted to any device,it keeps going into RESET ,go on and go on.when it connected to one device,this situation stoped.​2nd,BlueNRG-LP can connected to the android device ,and it works well as a keyboard.But when it connected to the Windows (10) PC,connection is OK，but the PC cannot receive the KEY VALUE of the keyborad. And more,I think the PC did not take the BlueNRG-LP as a keyboard device.​Could somebody tell me why,and how do I modify the program?Thank you very much!

Hi All,In the reference manual for the BlueNRG-LP Cortex M0+ microcontroller (RM0479), it states both page and mass erase functionality for the flash controller. But, only one "ERASE" command is given (0x11), which appears to be for page erase.Does anyone know if there is a command for mass erase (erasing the whole flash in one operation) and if so what it is?Looking at the source code for OpenOCD, it appears it could be 0x22. But, as this isn't stated in the manual, it would be nice if someone could confirm this.Many Thanks,Paul

Hello All,I am new to Bluetooth and would like to use the BlueNRG M2 as a hosted network co-processor. I am reading the Bluetooth LE primer from the Bluetooth SIG. Could someone please point me in the direction of some resources that allow me to use the BlueNRG M2 to send and receive data to an STM32L433 microcontroller connected bis SPI communication.

Hi.We are trying to measure analog values using BlueNRG-2.We want to calculate the accuracy, but we can't find any description of accuracy or drift for Vref (0.6V) or adc in the datasheet.Are there any reference materials or data available somewhere?Thank you.

Hi ST Community,I use the X-CUBE-BLE1 library and the SensorApp application, and I can understand most of the functions used, but when I want to add a value to my characteristic, I can't understand the address used and why.The address of the "environmental" feature is: 0x00,0x00,0x00,0x00,0x00,0x01,0x11,0xe1,0xac,0x36,0x00,0x02,0xa5,0xd5,0xc5,0x1bAnd then we say:uuid[14] |= 0x04; /* One Temperature value*/uuid[14] |= 0x10; /* Pressure value*/I understand that we're using a 128-bit personalised address, but are these 2 lines above enough for the ST BLE Sensor application to understand that we have a temperature value and a pressure value? And how do I change this value if I want to say that I also have a humidity value?Thank you for your answers!

Dear community, I'm using steval idb008v2. I'm trying to debug it with stlinkv2. Is it possible to do it or not? Do I have to move some pins or something similar? The application replies me that so stm32 board is not connected. Any suggestions please?thank you, Isabella    

I'm developing a power line communication with the ST7580. Sometimes I get an error code 0x08 returned by ST7580_DlData function. This code is not listed in Table 14 of the user manual. What causes this error?

Hi, We are using ST3485EIDT and ST3485EBDR RS485 IC in our Gateway device to collect the data from Slave devices. We are reading 30 parameters (1 Packet) from slave Device. Frequency: 1 parameter per sec. Baud Rate 9600 bps. We are noticing some issue while reading the data from the slave devices. Mean, some Parameters are some times not receiving, but most of the time we missing parameters, we can't guess which parameter to be missed. In missed parameter we are printing the reasons. reason will be Extra data size, Slave not responding. Even same issue happened, even if we read only 1 Parameters. Error rate will be 20 to 50%. Mean out 30 parameters we missed 10 to 20 parameters. If we are reading only one Parameter, out of 100 readings 50 reading are errors only, either data length Float or slave not responding. But same slave device modbus connected with PC using USB to Modbus Converter all the 30 parameters received without fail, all the time.We had repl

Hello, i am really new to pcb design, in fact this is the first time i done it. the problem i get is, where to do i connect the BOOT0 pin? i know if you connect it to VDD then it will boot from the system memory. if i connect it to gnd then it will boot from flash. it just i don't understand which one should i use. btw i am designing this board for a model rocket onboard computer. beacuse the last time i make it, i use multiple module and connect it with jumper cable. and it took to many volume, and i think should weigth more than a dedicated pcb. also if you can, can you also tell me what should i do after i finish the board (or maybe give a link to a document or video explaining it) and maybe review my schematic. i don't reallyhave confidence in my design, because i learn everything by myself and did it alone. thank you in advance

I am programming stm32411CeU Blackpill- i want to make connection between the Stm32 and Pc Via RS485 ..i wrote this simple code like in the photo..but i have problem with the output .. i get this weird characters like in the photo i tried different numbers and characters but i still get these weird characters (all Settings like Baudrate  are correct).. can anyone help me please .. after that i want to build up Modbus connection .thank you in advance        كل التفاعلات:١١ 

Hi, I'm new with this development board.My target is to use the S2-LP DK Application to configure the board to send data from a GPIO.Do I have to put my data on GPIO_0 and the clock signal to GPIO_1?Why is the clock signal needed?In this way it is possible to change also the modulation? For example I want to send my packet on OOK mode or FSK mode. Thanks

Where can I get the detailed technical manual of STSAFE-VJ100-CCC, such as the definition of chip pins?

Hi,I'm searching for UHF RFID reader IC (860-960 MHz). I found the one and only solution as "ST25RU3993". But it is NRND. So, what can I use for my new design. And is there any cheaper solution? This IC is very costly. If I ignore the cost as of now, please suggest me any other solution which is active.Thanks....

Hello thereI have a custom board based on STEVAL-IDB011V2 EVM. Is the same schematic but I have a problem with this. Apparently it boots but not run... When I flash "Hello World" example I have some issue that I can't check why.... The expected message does not is sent complete. So I have this output:In this test, I reset the board sometimes. Some times it shows "Applicat", "Applicati", (Probably bootloader output?) Some times it shows truncated "Hello World". I checked voltage levels by https://www.st.com/resource/en/application_note/an5503-bringing-up-the-bluenrglp-bluenrglps-devices-stmicroelectronics.pdf application note (bringing up the bluenrglp devices).I tried the Power Supply test (flashing DTM Firmware - UART without update) and VDDA thats we expect 1.2V, I measured 0V. The Core voltage (VCAP) I measured 1.2V as expected.I also tried flash other firmware examples without success.Can someone help me?
