Hello Everyone!I think it's a weird question, however, I am new to NUCLEO-H743ZI2. Actually, I am facing the issue of low-speed data transfer from MCU to PC (LabVIEW). Before, I was using programming and debugging USB ports to transfer data to LabVI...
Hi team,Is there any transceiver that has 2 channels and is ISO14230 or ISO9141 compatible? The most important is that this transceiver must supports 24 V in VBB pin (vehicle batery). Also is important that there is a level changer internally.
Hello,to reply to your request of information: "One open question for you, what kind of antenna do you plan to use to cover both 433 and 868MHz with a single antenna matching circuitry ?"I attach a picture of the antenna vertical sleeve @ lampda/4 wh...
Hello. ST team.i'm using L9369's voltage measurement function.i read L9369 manual, and i send below SPI commands(no.0~6) for initial driving.(my purpose is to drive FET : HS1 A, B ON / LS2 A,B ON)00xb5019ff810xb5a15fef20xb720b54d30xb480aa9840x40a0000...
Hello, I measure the output differential voltage of the drivers (with 100ohm termination resistor) and it is always higher than 0.4V that is referred to the datasheet. What I measure is about 0.68V. Is that normal? Thank you in advance
Good afternoon, We are evaluating the possible consequence for the LVDS transceiver RHFLVDSR2D2 in case that it is supplied with a voltage above its absolute value which is 4,8V.In particular we are asked to evaluate the case that voltage applied to ...
Hello to everyone. I am trying to see the data via I2C with the capacitive sensor (FDC2214-Q1),but I see the values I have assigned as 0 in live experiment.I'm sure about the hardware part. I would be happy if you help. /* Private define -----------...
Hi ST community,does the STUSB4500L also supports negotiation for data communication?E.g. can I use D+/D- pins of the USB-C port while PD is negotiated by the STUSB4500L?The STUSB4500 seems to support that by setting the flag USB_COMM_CAPABLE within ...
I have run into problems trying to get voice data from the MP34DT05-A PDM Microphone on the BlueNRGLP eval board. Specifically, and after spending a fair chunk of time (using the BLE_Sensor_Demo_BlueMSApp demo code as a starting point), it appears th...
Hello,I'm using a BlueNRG-2 via SPI from a main uC host. The BLE stays advertising and the main uC goes to Standby mode. When someone tries to connect to my device, main uC wakes up. Since I don't want to restart the BLE (this would reset our addres...
