4-20ma or 0-10v dc to 0-3.3 analogue ip of STM32 circuit?

I want to interfacing industrial analogue sensors with STM32F030C8T6TR so I need to convert signal in to 0-3.3v signal.4-20ma to 0-3.3v0-10v to 0-3.3v​1) For converting signal which is good way using opamp or voltage divider?​​2) It is possible using...

Hi Team, I want to learn the i2c features and functions while using STM32F4 Discovery kit based on STM32F411VE and communication with LSM303DLHC. I want to know if there is any deault register selected in LSM303DLHC when no register value is mentioned.

In this for the i2c communication I am planning to use LSM303DLHC for undersatnding the i2c communication and the protocols. I want to learn more about the driver API like i2c_init(), i2c_read(), i2c_read_with_no_register etc.. Kindly suggest me a wa...

Linux Driver for MP23DB01HP PDM Digital Microphone

I'm looking for instructions on interfacing MP23DB01HP Microphone to Cortex-A7 on STM32MP157 through I2S bus.The application note AN5027 is a good starting point but does not mention how to integrate with Linux on Cortex-A7.I've modified the devcie t...

I did not see an 'ultrasonic' forum-related category so I am posting the question here: Is it possible to do an excitation 'sweep' such as LFM or a binary encoded pattern with the STEVAL-IME011V2 (or any other ST ultrasonic driver product)?

Housing for inclinometer using MEMS, that leads to low deviation over a temperature range from -10°C to 40°C?

(1) Are there best practice examples available?(2) Can I glue the top side of the MEMS to a steel surface? I expect lower temperature deformation than when fixed with the PCB. Or does the steel surface deform the MEMS in the mentioned temperature rag...

H3LIS331: SPI read response is always 0x00

Hello, I am attempting to communicate using SPI with an H3LIS331 accelerometer. The H3LIS331 is on a custom board that originally had a LIS3DSH on it. The LIS3DSH had been working without a problem, but we were looking to expand the acceleration scal...
