RS485 3.3V or 5V IC For Larger Distance

Hello, Our application needs longer distance RS485 communication, So, From 3.3V and 5V RS485 IC (available in ST), which to choose for larger distance coverage?Thank You

What is different between ST3232 and ST202?

I knew that ST202 is compatible for ST3232. So I changed only ST202 into ST3232 without any circuit changing.But ST3232 doesn't work.​What is different between ST3232 and ST202, other than power supply voltage?​I found the difference in typical appli...

Facing issue in the DeviceConfiguration() function while initialization of BlueNRG2 chip.

We are using BlueNRG2 chip for our BLE application. For the Information,We have connected 32MHz external crystal oscillator in HS Pins..We haven't connected any external crystal oscillator at LS Pins..And we haven't connected any inductor at SMPS pin...

Why is SPI not working without a floating wire on the MOSI line in SPI?

I've connected the cno410 LED Driver to NUCLEO-F446RE which works with SPI lines, whenever I've linked to it directly, it works as expected. we have designed another PCB shield on the Nucleo board. On top of we have connected this LED Driver now. Now...

Hi, We are using Vl53L1x laser TOF sensor , We are powering the ans shutting it down using XSHUT every time we make the measurements , After Power up we check communication on I2C by reading the Boot State,

But some time Mcu is unable to read vl53l1 .Do anyone has faced, such issues with the chip, appreciated.

Repeat scanning

Hi everyone,I am developing a simple scanner using the BLUENRG-M0 from ST. I have a custom board wtih an MSP430F5255I just want to make multiple scan to discover other device of interest around.I am following the ACI API from ST and my first scan is ...

Bluenrg-2 sample project getting error on compilation in Keil

Dear Team, I have Bluenrg-2 devlopment kit and STSW-BLUETILE-DK 1.3.0 SDK. I am using Keil-ARM, compiler V6.19. now I have runed sample project BLE_SensorDemo and others sample projects also getting error:../../../../../Library/SDK_Eval_BlueNRG1/src/...

Is ST4SI2M0020TPIFW already pre-programmed for Inmarsat profile ?

BlueNRG -2 Sensor-demo code not working.

Hi Team,I am using stm32l475vg MCU and board is B-L475EIOT01.If I create sensor demo project with BlueNRG-1 then it is working properly but If I create same project same configuration with BlueNRG-2 then it is not working.It is stuck in here for Blu...
