I've been working with the STEVAL-STWINT1B board. I want to measure and record 2 analog signals. Only ADC1 input channels IN5 and IN6 are available as single ended inputs and are accessed by PA0 and PA1 GPIOS. They share the inputs with the microphon...
Hi, We want to interface the IW612 NXP module(LBES5PL2EL-923) with the STM32 MCU and use it to communicate with Wi-Fi and BLE. We want to use the STM32 host to communicate with both BLE and Wi-Fi.Does the STM32 provide any specific drivers to commun...
I would like to know what chip antennas are recommened to use with Spirit1 chip. Also schematics to see how matching is done and PCB layout would be of great help. Thanks
Hi, recently I got a X-NUCLEO-BNRG2A1 and I am trying to use it with NUCLEO-G070RB without success. I have created a project with STM32CubeMx assistance using SampleApp of X-CUBE-BLE2, mapping the pins of the expansion board to my nucleo board as fol...
Hello,I hope you are well.I have a question about the certification of the “Programmable Bluetooth® Low Energy wireless SoC” from the “BlueNRG-LP” family: are they BQB certified?Thanks in advance
I've bought a S2LP dev board STEVAL-FKI433V2 as I'm evaluating the S2LP for a product revamp.Because it will be used with a legacy system I want the receive side to completely bypass the packet decoding and output to GPIO - which seems to work to a p...
Hi.Please can someone tell me whether Part No: M24LR04E-RMN6T/2 (RFID Transponder) is able to communicate with MiFare Desfire ?Application will be a custom designed PCB to be used as part of Prepaid payment system Thanks
In AN5041 Rev 5, pages 26-28, there is an example programming sequence for the STEVAL-IDP004V2 master and a device on a STEVAL-IDP003V1 using ST's customized protocol (a substitute for IO-LINK).Is there a manual or tutorial or resource page that goe...
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 !
