Hi all,As IQ samples are used in the direction-finding feature, I am wondering how I can extract the phase information from the sampled IQ data. I tried to extract the phase by arctan(Q/I), but it changed very quickly. Is this because of the low IF a...
Has anyone in the community used the ST7540 PLM in an airport environment ? I am working on a FAA contract that requires PLC control of multiple lighting cabinets over a distance of 1 kilometer. Any feedback would be greatly appreciated !
Hi, The current design requirements for a Fire Panel system, demand power line communication over a distance of more than 1.2 km. More than 254 devices (detectors) would be interfaced to the main control panel. Suggest possible feasible solution for ...
Hi, I'm currently learning how to create an IO-LINK device using the NUCLEO-G071RB and X-NUCLEO-IOD02A1 and configure it to operate in Transparent mode. I have already used simple SPI communication to adjust the register parameters within the L6364 t...
Hi.,Good after noon., we are using LBEE5HY1MW-230 and WSM-BL241-ADA-008 wife+BLE module for Our Smart lock controller board adn Processor board, sometimes this module was disconnected/does nor Shows the Bluetoohth after Commission and decommission p...
We have purchased an ST60 development board for wireless data transmission. Where can I find more information about- We do not have an electrical circuit for the ST60 debug board, we need a circuit for connecting to an external control board. - We ne...
I have seen some thread about this topic but it's still not clear to me.I'm using the x-nucleo-BNRG2A1 which embed a BNRG-M2SP. Is it possible to increase the ATT_MTU size ? for example in the sample example code we do a aci_gatt_exchange_config(conn...
Hello,Good day!We have a RS485 communication system and we are usign the ST485B, but we recently had an issue with a couple of PCBs(attached picture)We are using an external DC/DC converter as 5V power supply (attached schematic). I followed applicat...
Hi,Is there any information regarding whether there are internal clamping diodes to VDD and GND on the open-drain outputs (RP_1A5, RP_3A, ATTACH, ALERT, A_B_SIDE, GPIO) of the STUSB4500L device? If these outputs have external pull-up resistors that c...
Hello, I've designed a board based on the EVB schematics and layout. I need to output a frequency of 1250 MHz.I managed to make it work with the on-board 100 MHz oscillator, and it works well with 25 MHz external clock, but I can't find a way to use ...
