Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
We are looking to add a pre qualified bluetooth module to a consumer product and the device live outdoors and periodically connect to a phone. We have identified the BlueNRG-1 as a candidate but perhaps there is a better choice. How well is the BlueN...
I have a BlueNRG-M2SP on a board with an STM32 Host. I assert the boot pin high and reset the M0 at the start to put it into Bootloader mode. I wait for the popup and set the baudrate, so far so good. When I issue a command with the Flasher Utility i...
Hello everyone,I've been trying to load profiles that are not from Truphone onto the ST4SIM, but all I get are errors. The most basic question I cannot find an answer to is whether the chip does not allow loading profiles from external companies.I'm ...
Currently, I have two STEVAL-IDB011V2 boards (as shown in the figure). One is to send the signal as a transmitter, and the other one is the receiver. After the channel (between Tx and Rx) modulates the signal, how can I extract the carrier signal wit...
Hello,During testing with the STUSB1602, I encountered strange behavior when using the DRP-mode. Connecting a USB power bank in this mode does not result in a successful connection. Only after pressing the engage-button on a Powerbank, the connection...
Is it required to put external TVS diodes along with the ST4485EB RS485 IC on the A and B lines? I see the datasheet and notice that there is in-built ESD protection as shown in the data sheet snapshot below. Please advise.
Hello together,is there any part marking decoder for STM devices ? like Micron Technology or TI have.Best RegardsPatrick
I have some following up questions after my last post: https://community.st.com/t5/stm32-mcus-products/lsm303dlhc-c/m-p/597950#M224881. I now have a code that does not give any errors. with the librarys in the picture below. But when i run the code a...
Hello Team,I am trying to read some data with the nucleo-L552ZEQ peripheral using the SAI peripheral in asynchronous slave mode configured in TDM Mode.In the attached above, Ch0 is the FS and CH1 is the SCLK signal. I've configured the following:1) F...
Good DayI am using Spi with Dma. When using the Hal-function "HAL_SPI_Receive(SPI_HandleTypeDef *hspi, uint8_t *pData, uint16_t Size, uint32_t Timeout)", I want to receive 1000 times Data , which I can set in the size-area. The Problem is that my Spi...
