Hello Team, We are currently investigating an issue related to the SPI communication between the STPM34 sensor and the STM32F4 microcontroller.At system startup, all values measured by the STPM34 remain stuck at zero. Even when voltage and current ar...
We are designing a 6-layer PCB with limited board area. The layer stackup is as follows: TOP / GND2 / SIGNAL / POWER / GND5 / BOTTOM.Due to space constraints, we are planning to place one STPM33 on the TOP side of the board, and another STPM33 rotate...
Hello everyone,I am working with the ST67W611M1 Wi-Fi/BLE combo module alongside the X-CUBE-ST67W61 middleware running on an RTOS.My goal is to put the module into its absolute lowest power state. According to the datasheet, the Shutdown state consum...
Use of WiFi CSI for sensing seems to be getting quite some attention lately; eg,https://www.linkedin.com/posts/wi-fi-consultant_wifisensing-csi-80211bf-share-7467261785717518336-b5KK/https://www.linkedin.com/posts/hex-labs-9a9914376_esp32-wifisensing...
Hi all,I’m exploring whether the S2LP LDC mode can be adapted for a transceiver configuration.From what I understand, ST’s example code provides separate implementations for RX-only and TX-only devices. Using these individual examples, I’ve verified ...
[Part Numbers] NUCLEO-F446RE, ST67W611M1[Environment] STM32CubeIDE Version 2.1.1, ST67 Firmware Version V1.3.0[Details]Currently, the FOTA code generated by STM32CubeMX can only update the ST67 firmware; the F446 firmware cannot be updated.Furthermor...
Hi! We have two custom boards that we have soldered the ST4SIM-300M eSim to. We have earlier been using the ST4SIM-200M and followed this activiation procedure:https://www.st.com/resource/en/application_note/an5740-st4sim-with-truphone-connectivity--...
I'm trying to configure the S2-LP with the following settings:- Base frequency: 915 Mhz;- Modulation: ASK (modulation depth 90%, '1'=10dBm and '0'=0dBm);- Data rate: 80kbps;- Channel space: 389kHz;- Channel: 0. I've developed a HAL because using the ...
Hi all,I was super exited to test the new STUSB4531 IC on the EVAL-SCS006V1.The PPS support of the chip is the main reason to pass over from the STUSB4500. I have done a lot of test with 100W PPS enabled USB-C supply but without luck. i did not manag...
Hi @Peter BENSCH , We are using the STKNX IC to generate the 12V supply (for latching relay operation) in our products since 2023. Its KNX UART is not utilised. The value of CIN capacitor used is 0805 10uF/50V MLCC Capacitor. In Datasheet, recommende...
