We based our circuit on the "STKNX Reference Design" (V1.0, 14. Nov. 2019)).In the case of the single fault condition of a shorted CFH capacitor during operation almost the whole KNX bus voltage (21-30V) is permanently over the 68R resistor (RTX) and...
Hey All,We are scratching our heads. These STEVAL-STRKT01 work fine for an hour than just stop transmitting. We are using STEVAL-STRKT01 discovery LoRa Asset Tracker Dev-kits in Region US915 with a MachineQ Area-8C 8-channel gateway. Installed the la...
Hi! I am trying to built this ToF rangefinder using this tutorialBut instead of using the VL53L0X I am using the VL53L4CXI have attempted with 2 different ESP32-C3 Controllers and 2 separate VL53L4CX sensors and no matter what I do I can't get any I2...
Hello Everyone,I am using BLUENRG-2 (STEVAL-IDB008V1M) and I have created new 4 custom primary services but only 3 are visible at a time. Is there any way to increase its count?Thank you for the help
Hi all, I've just bought a STEVAL-IDB008V2 board, but I don't find any tutorial or ressources like get stared, the only doc I've found is https://www.st.com/resource/en/user_manual/um2094-getting-started-with-stevalidb007vx-stevalidb008vx-and-stevali...
Hello,Looking at the documentation of the M2SA module, I noticed that the function of the same pins (21, 22, and 23) differs between the datasheet and the application note. Does anyone know the exact function of these pins? M2SA - application noteM2S...
Hi,I am working on the LIS2DU12, but unfortunately it does not yet work as I expected. I do a reset and wait with the status bit of reset until it is done. The system is therefore in power-down. I then set the drdy. This immediately triggers the int...
Hello, this is LewisI have a question about "STUSB4500 NVM Customer Sector0-4 Write".I would like to know the message below from the technical note "STUSB4500 NVM Register Description and General Access".(attach file)"Load NVM data sector 0 (8 bytes)...
In the datasheet of the BLUNERG-M2 module, it states the following:"The BlueNRG-M2 module allows applications to meet the tight advisable peak current requirements imposed withthe use of standard coin cell batteries. Optimized results are obtained wh...
I can't get my L9663 SPI working. My understanding is that any 32-bit data I send to MOSI will return a 32-bit data from MISO. However, I am not getting any response; MISO remains low the entire time. I am now using a QFP32 general adapter boar...
