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...
Hi Everyone,I'm trying to use setup a simple example by using BlueNRG-2 mounted on STEVAL-MKSBOX1v1.By following simple instructions found on User Manuals and replayed on YouTube video, it looked easy to me to setup a VirtualCOM port Example. Everyth...
Hi Everyone!I'm quite new to BlueNRG-2 and it's not clear to me, in general, what is the purpose of BLE Manager.Could I develop a BLE application withoiut it (I guess yes :) )? Which are the advantages to use BLE Manager instead of not?Thanks a lot ...
Good dayI have a STEVAL-MKI173V1 which is for the LSM303AH.I have to integrate this on a project in VS code, as there is no Zephyr driver for this, I am trying to implement this directly on I2C.The device has two addresses one for the accel and the o...
