I have a circuit card that uses the M48T18-150PC1 Timekeeper SRAM, and the battery died. I replaced the part but the settings did not save once power was cycled. A second part was used with the same result. Looking at the date stamp, (412) tells me I...
Hello, I implemented a project using STUSB4700 to provide a charge to an Android tablet, the power interface is resolved using this topic https://community.st.com/t5/others-hardware-and-software/stusb4700-constant-output-switching/m-p/734155 because...
My team is trying to design a radio board with the STM32WL and we plan to use the BALF-WL-00D3 in the RF Front End.Based on our requirements, we have decided to go with a 6-layer board and are trying to decide on a stackup (dimensions) for the same....
Can you use CubeMX to generate init code for the LP SoC?I am integrating an LP SoC into a custom PCB and not sure what all I need to init?
Back in May of 2022, I purchased a number of BlueNRG-LP-DK development boards (STEVAL-IDB011V2-C) for Bluetooth Low Energy development. Things went fine (in a manner of speaking of course) .Recently I tried to use these boards with its RTC (Real Tim...
Hi, I am evaluating to use the ST8500 module as alternative part of the ST7538Q.In our application we have a custom protocol over power line with FSK modulation.Looking all the documentation related to ST8500 I found that it is possible to configure ...
Hello all,I am working on creating a secure IoT device. The device is configured as MQTT client which will be sending sensors data to the sever over MQTT. I have implemented encryption using mbed-TLS where I confirm server's authenticity with server ...
Hello ST Community,I am working on a project that involves implementing the STUSB1602 to act as a USB Power Delivery (PD) source while maintaining USB 2.0 data passthrough functionality. I would like to know how to best approach this design and which...
