HAL_I2c_Mem_Read() failed

Hi,I'm using HAL_I2c_Mem_Read(), too.And may I ask if STM32's I2C can generate wave like the following picture. I have tryed Mem_read() and any other function in i2c.c , but the bit following device addres is "0",which means "write" in I2c.eg.I want ...

Sending Data between QI Devices

I've bought two ISB042V1 and i want to send sensor Data trough the QI connection from the Rx to Tx. But i do not understand how i can write data from MCU1 into Rx device, and read out from Tx device into my MCU.

Overall impression of SPIRIT1 radio ICs ?

I have been attempting to use Silicon Labs Si443x/RFM22 ISM radio IC for over a week now with no success. My overall impression of this radio IC is poor. Lots of issues, erratas, and twitchy-spazz operation even under ideal conditions. So naturally I...

S2-LP 403MHz

Hi All, Currently S2-LP only supports down to 433MHz, would it be possible to use a lower frequency crystal to achieve a lower frequency such as 403MHz?Thanks!Xarion

SPBTLE-1s Example Project Run

Hello, I am evaluating SPBTLE-1s module. I am working on a example project provided by the BlueNRG-1_2 DK 3.1.0 (remote control). The project build on truestudio and is burned on chip via st link utility. Application success messages prints on the se...

We are using your sensortile (STEVAL-STLCS01V1) for our project.when we connect sensortile on cradle kit LED glows but it is no visible on blue MS app.

We have a project to establish the communication of MCUs with SPIRIT1 module. First, we use STM32 Nucleo SPIRIT1 X-NUCLEO-IDS01A4 and Nucleo development board NUCLEO-L152RE to test point-to-point demo function based on CubeExpansion_SUBG1_V3.0.0.
