Interface and connectivity ICs

I designed a USB-PD circuit using STUSB4500QTR. Circuit is error free and it shows the correct I2C address when I scanned using I2C scanner. But I can't able to configure the PDO profile using the STM32F072 nucleo board and GUI. I shared here the screenshot of the errors. Please help to get solve this issue.

I am interested in using the built-in 2.7V LDO on the STUSB4500 to power other parts of my circuit. Do you have any information on how much current this pin can source? And is the LDO hooked up to whatever VUSB is set to? For example, if the circuit is pulling 20V over USB, is the LDO hooked up to the 20V rail?Thank you for your help!

I see that all examples are for IAR or KEIL IDE.Can you provide CubeIDE projects as well?Regards,Piotr Romaniuk

(Please let me know the Parts ST26C31BN(4/0 Driver RS422, RS485 16-PDIP) is Active/Discontinued. )

Hi,I would like to know if L9637 transceiver can be used with LIN protocol.I would also like to know if this transceiver can be used in a system bus where there are many Electronic Control Units (ECUs) and their communication is through of K-line and L-line. 

Dear all.I am working together with a company facing a problem with TESEO-GNSS-Receiver in Japan. In an automotive usecase, with low SNR, the receiver gives us a wrong position, we've seen it off by up to 200 Meters. This alone would not be too bad, but together with the wrong position we get Fix=3D and low DOP-Values, so we must trust the position and we get lost in the countryside while actually driving on an Expressway. The GPS-Position is typically following the actual position in parallel, but with large offset. As i know this is kind of hard to understand, i'll attach a screenshot of Teseo-Suite pro with a recorded dataset. Map shows positions far east of the Expressway, SNR for all 17 Sats in use are around 30, best 38, lowest 19To my regrets, we do not get the information, which chip exactly they use and what the configuration is like.I got some hints, though, from analysis of field data:we see very precise position even with low SNR (< 30dB) most of the timewe see the probl

Hi ,I am working on STM32L0 series controller with VD6283TX ALS on I2C interface.Though code is available for the sensor, my requirement is to write own code that will control the sensor. Sometimes it reads the RAW data from sensor and sometimes it gives 0 values from sensor. I am confused why this is happening. Please suggest the way to get consistent output from the sensor. Here is my code-i am using ReadChannelValue(uint8_t channel)to read the output of particular channel#define SLAVE_READ_ADDR (0x41) #define SLAVE_WRITE_ADDR (0x40)   #define I2C_TIMEOUT (100)   #define INTERRUPT_CTRL_REG (0x02)   #define ALS_CTRL_REG (0x03) /*config param*/ #define ALS_EN (0x01) #define ALS_CONT (0x06)   #define ALS_PERIOD_REG (0x04) /*config param*/ #define ALS_IM_PER (0x32)/*1 corresponds to 20.5ms->255*20.5 =5.22s max period*/   #define CHANNEL6_ENABLE_REG (0x2D) /*config param*/ #define CH6_EN (0x01)   #define ALS_CHANNE

Hi, I am looking for typical application in the datasheet (for example - ST4SI2M0020TPIFW) and and find nothing. Do you have some typical schema? What does the eSim connect to? What else is needed in the way to the processor? Thanks for examples

I spend whole day traying establish communication between NUCLEO-F)42k6 and CO2 Sensor SCD30 https://www.sensirion.com/fileadmin/user_upload/customers/sensirion/Dokumente/9.5_CO2/Sensirion_CO2_Sensors_SCD30_Interface_Description.pdf I have connected SDA line from Sensor to D2(PA12) on Nucleo and SCL from Sensor to D8(PF1).GND from sensor connected to GND on Nucleo and VCC from sensor conected to 3.3 on Nucleo.I'm using STM32 Workspace and in STM32CubeMX perspective I have configured GPIO pins like described above. Additionally I set No pull up and No pull down for SCL and SDA as it look like its done on sensor board by manufacurer. GPIO Mode Alternate Function Open Drain.

Hello all,I am attaching the schematics for a PD sink system we have designed and built. Our aim is to get this sink system to accept both PD and non PD type C power supplies and transfer their power to the 'FRONT_PWR' path on our schematics.Of course a microcontroller is connected and controlling the PD parameters, etc. A few questions:Is this schematics correct?If a 15V/3A type C (non PD) power supply is connected, will this system accept it and transfer it's power?We are having an issue where sometimes when a power supply is connected, the power output will work for a fraction of a second and then shut down. What could be causing this? Thank you very much for your help!Nir.

I have been searching through the ST website to try to find the BlueNRG stack image v2.1c (the bluetooth 5.2 compliant version). If I search "stage image" under the "Tools and Software" section, I get results for other versions (such as STSW-BNRG-V63, STSW-BNRG-V64, STSW-BNRG-V73) whose release notes have older dates despite having higher revision numbers.

Here I'm using a USB Interface IC DRP for OTG. when I look into the datasheet for interfacing, I find some details in the pinout contrary to the diagram for pin numbers 16 and 17. Please someone clarify in this  

Hello,I program a BLE, I can send and receive data with the ST BLE Toolbox application.I want to use another application that is not programmed by the ST community to communicate with my server, I can receive data from this application but I cannot send it.Do you have any suggestions?

One of the main advantages of Power Line Communication is its ability to provide reliable communication over long distances.It is also relatively easy to install and maintain since it uses existing infrastructure, which makes cost-effective solution for many applications.

Hello,I would like to connect a TESEO LIV3F to an STM32 MCU that is powered using a 2.4v supply.Im wondering if I can drive TESEO's Vcc_io with a 2.4v supply or if I should use a 3.3v according to the datasheet and put a level shifter between them both.The first option is far the best for me ...Thanks,

Hello, In one of my projects, I use BLUENRG-M2SP as a network coprocessor with a host microcontroller from STM32L0 series together. I flashed BLUENRG-M2SP with pre-compiled DTM_SPI.hex which is used by X-NUCLEO-BNRG2A1. My application code is run by host uC. Default BLE firmware is used as I indicated  (BlueNRG-1_2 DK 3.2.3\Firmware\BLE_Examples\DTM\BlueNRG-2\DTM_SPI.hex) In this configuration, it operates as expected well. But, I would like to use my custom Mac address. To do that I have 3 questions;  1) As I understand from application notes & community forum, to use my custom mac address, I need to write it to a specific location of flash (I have done it by BlueNRG-X Flasher Utility while flashing firmware). and then I need to read from the flash again and write it down  by following: ret=aci_hal_write_config_data(CONFIG_DATA_PUBADDR_OFFSET,CONFIG_DATA_PUBAD DR_LEN, bdaddr); am I right ? 2) If I am right, should I read

I am trying to develop some custom code using the BlueNRG-2 chip. I have my own custom board but first I am trying to get things to work on the STEVAL-BCN002V1 blue tile. That board comes preloaded with the Sensor Demo which worked fine. I am using the latest KEIl IDE for the BlueNRG series. I also dowloaded all of the recent DK files for the Tile board and the BlueNRG. I opened the Sensor Demo in Kiel. It compiled correctly. It seemed to download ok and the board ran as normal. Then I tried a few other examples such as the remote control. This also compiled and downloaded ok. This also worked as normal. When I went back to reload the Sensor Demo, Keil couldn't find the board. I ended up using the BlueNRG utility and that allowed me to connect and erase the chip. Then Keil downloaded the SensorDemo again with no problem. However, the code doesnt work. All I get is a green LED lit. I cant even run the debugger, it never starts anywhere. If I go back to the remote control firmw

Hello,i need to know if you recommend to use the BALFLB-WL-08D3 at 433MHzI design my PCB with the STM32WL54CC, and it will operate between 433MHz and 435MHz. i want to know if the BALFLB-WL-08D3 is suitable for my application or if is better to design RF line with passive components. Thank you,Sincerely.

I am working with BlueNRG 2, and Tile both... I'm working in BlueNRG-1_2 DK 3.2.3. In the xx\BlueNRG-1_2 DK 3.2.3\Firmware\BLE_Examples\BLE_SerialPort\BlueNRG-2 folder, there is Server bin and hex files which work great. However, when I go to the C:\ST\BlueNRG-1_2 DK 3.2.3\Project\BLE_Examples\BLE_SerialPort\EWARM\BlueNRG-2 folder, there is only source code for the Client. I need the Server source/project files that were used to build the bin and hex.
