Posted on August 14, 2015 at 19:20So if I want to hop to various frequencies I need to calibrate the VCO each time. That's fine and expected. The SPIRIT1 has a fantastic auto calibration time of only around 50us - one of the features that make it at...
Hello! The task is to implement a device with two-port Ethernet. To do this, I developed a circuit, connected the STM32F207 controller to the KSZ8863RLLI Ethernet transceiver via RMII. The controller and the transceiver are connected according to the...
Hi folksI am currently trying to communicate with the TLV493D-A1B6 3D hall sensor. As board, I'm using the NUCLEO-F103RB. To make sure I didn't mess up any connections or anything else, I verified my setup with an ADS1015 adc which I can read out ove...
Dear everyone,I'm trying to use a SX1280 for RF connectivity.My dev board is the official... the SEMTECH "SX1280ED1ZHP", it's included a nucleo + daughter board with SX1280.My diffculty is that a not able to read correctly a register with a know valu...
Hi everyone,I'm currently using an STUSB1700 as a 5V 3A power source for one of the USB ports in my project. I'm able to draw up to 2.7A with Apple devices (iPhones and iPads) on that port. Using the STUSB GUI, I can connect to the STUSB1700 via I2C ...
Hello,I am currently reviewing the S2-LP transceiver for high-bitrate/long-range communication in the 915MHz band. To achieve that, I want to interface an S2-LP with a Skyworks SE2435L front-end, as shown in the FK915V1 Evaluation board. I would like...
Hello, I'm evaluating the use of the evaluation kit and the evaluation software for the S2-LP to generate the OOK signal, In the software I can't modify the Preamble to a custom pattern, another thing is to be able to place the ID address (I can not ...
Posted on July 06, 2017 at 01:27The BlueNRG-MS library for BLE v4.1 sets ATT_MTU to 23 bytes. Is it possible to increase this limit as long as it's less than the 255 character value length limit?I am working with the SensorTile eval board with an ST...
Hello everyone, I am experiencing a voltage issue between the IO-Link master and IO-Link devices in my new project based on IO-Link communication. The setup involves a STEVAL-IDP004V2 IO-Link master and a STEVAL-IDP003V1 IO-Link slave/device. I hav...
I bought a P-NUCLEO-IOM01M1 last week and downloaded the software from TEConcept, IO-Link Control Tool.Then I tried to connect P-NUCLEO-IOM01M1 but it was failed with an error message, MASTER_NOT_CONNECTED.I haven't changed anything on P-NUCLEO-IOM01...
