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...
Hi, I'm interested to learn if the BlueNRG-LP chip 355AC can be set in dual mode (which is possible from example code), but over 2 different PHYs. I want the chip to be a central device over coded PHY to connect with sensors and over 1M PHY to talk...
Hi, I am trying to use the BLE (SPBTLE-1S chip) on my STWIN to send acceleration data, and receive some parameters. My first idea was to use a template from X-Cube-BLE1 with the following configuration : HCI_TL : BasicHCI_TL_Interface : UserBoardAppl...
Hi all,i have an STEVAL-MKBOXPRO that i want to reprogram.I found STSW-MKBOX-BLEDK here https://www.st.com/en/embedded-software/stsw-mkbox-bledk.html#documentation and specially example BLE_Sensor_DemoI follow "UM3227 STSW-MKBOX-BLEDK software packag...
I'm trying to build example GPIO_IOWakeup with Keil IDE based on BlueNRG-1. I got this screen.What are the necessary steps to activate building and set up necessary parameters?I try with this activity:What to do?
Hi I have connected Bluenrg LPS eval board (network coprocessor mode) with STM32L476 Nucleo board and both are connected via jumper wires.I'm transferring 30 bytes in a single packet from STM32 nucelo to Bluenrg LPS module what I have seen is, once s...
Hello Everyone,I am working on a product and recently due to chip shortage I have to change the IMU. I have selected LSM6DS. My MCU is Esp32. now when I send a query of I2C address it responds with 0x7E address while it should be 0x6A. I was using Ad...
Hello everyone I am looking into the STPM33/34. I only want to use 1 SPI bus for both ICs and select it with the SCS. In the datasheet I cannot see whether the MISO goes into tristate when the IC in question is not active. I also cannot see any infor...
