Interface and connectivity ICs

I am looking for reference circuit designs for the spirit1 low power sub-GHz transceiver. The data sheet is limited and the design references is no longer on ST. Does anyone have more information about layout and setup?

I have found modules for 433MHz band but I need to design a circuit for ~169MHz (VHF band).I'm unsure of the matching circuit and which components to use.Any help would be greatly appreciated.

Why return code of BlueNRG-X_Flasher_Launcher.exe is always 1 when calling it through C++

Hello,My C++ code calls BlueNRG-X_Flasher_Launcher.exe with all relevant arguments. I can successfully program the BLE module STB1132-25. I have used the c standard function system(const char*) to call BlueNRG-X_Flasher_Launcher.exe. the issue is, wh...

Hi All, I have a question about ST digital isolator: in the datasheet of STISO621 i find two parameter: Refresh time and Watchdog timeout, can someone explain me the meaning of these parameter? thank you

Here the datasheet, see on page 4/21 or 5/21https://www.st.com/content/st_com/en/products/interfaces-and-transceivers/isolated-interfaces/stiso621.html

STEVAL-IME009V1 (STHV-800) : Unable to connect to Win10 PC via USB

According to the datasheet (AN4471), connecting the board to PC via the USB should cause specified LEDs to light up to indicate ready to use but not all did (D23, D4) and I was unable to connect the board to programs provided by ST intended to upload...

Its possible use the teseoliv-3f for aquisiting velocity? Is there documentation for this?

Hi, i am working on a Project where i have to use the transmitter S2-LPTX, the problem is i dont know the values that i can use in for the matching capacitors and inductances in the schematic circuit .!!!

In the AN5203 application note teseo-liv3F (I2C positioning sensor) in the page 17, in the main code, line 9, what type of variable read_buf[180-1] ?

BLUENRG-M2SA kernel configuration linux

Hello everyone. I am using the BLUENRG-M2SA with the processor SAMA5D27 Cortex-A5 in a linux system. I communicate with it by uart. I have set the kernel like the ubuntu site advises (https://ubuntu.com/core/docs/bluez/reference/device-enablement/lin...

I am planning to test S2LP in Tx mode and want to see the data transmitted on the oscilloscope. How do I provide the synchronization signal for the oscilloscope?

I am planning to test S2LP in Tx mode. I was considering to observe the data transmitted by S2LP in Txmode on an oscilloscope. How do I provide the synchronization signal for the oscilloscope? Or alternatively, is there any way to what is the data tr...
