STM32L5 – Excellence in ultra-low-power with more performance – Based on Cortex M33

Security has emerged as one of the 3 key areas that developers of embedded and IoT applications are thriving to improve. The STM32L5 microcontroller series is the solution and provide a new optimal balance between performance, power and security.
The STM32L5 MCU series harnesses the security features of the Arm Cortex-M33 processor and its TrustZone for Armv8-M combined with ST security implementation. ST-proprietary ultra-low-power technologies create a class-leading MCU for energy-conscious applications such as Internet of things (IoT), medical, industrial and consumer.

Some Tips & Tricks regarding IP (Internet) Camera

We using different IP Cameras, seems to easy install its but is not true.
Normally the first installation work well but if you change your Internet Provider or update the IP camera SW, born a problems !
Also if you install a WiFi repeater or Switch ethernet sometime born some problems.
Below there is a list of things to control for resolve IP Camera problems.

How to use 3 channels of the ADC in DMA mode using CUBE-MX and ATOLLIC

For develop this project the use the NUCLEO_L031K6 (32 pin Nucleo Board), CUBE-MX and ATOLLIC.
We assume that you have familiarity with this tools, in other case see our dedicate tutorials to CUBE-MX and ATOLLIC.

For more info see here.

DC motor with Honeywell Hall sensor (it’s used like an encoder)

In the image below there is a low cost DC motor (in my case is a 24 Vdc motor).
This is a typical DC motor used for automate a gate, shutters, etc.

STM32 GPIOs interrupt & Atollic


The GPIOs has 16 interrupt lines.
All pins with same number are connected to line with same number.
They are multiplexed to one line.
Each line can trigger an interrupt on rising, falling or rising_falling edge on signal.

BLE 4.x – 1 Mega bits per second is just wrong

Still confused about how fast you can really send data over Bluetooth Low Energy v.4.x (BLE) ?
It’s not just you.
A google search will turn up many incomplete answers.
Each OS and device has it’s own restrictions, such as connection interval and number of packets per interval.
For example, did you know that with iOS you can send 4 packets per interval, and that HID devices can communicate 2.6x faster ?
If you want to finally clear up how fast you can communicate over BLE with an iPhone, Android device, or Mac, read on.

Come configurare le telecamere Foscam modello FI9818W e similari con connessione via FastWeb – In Italian Language

How to configure Foscam model FI9818W cameras and similar with connection via FastWeb – In Italian Language

Concetti Base

Le telecamere che si installano è meglio che abbiano un indirizzo IP statico e non via DHCP ovvero assegnato dal vostro router.
Per fare ciò, nel menù delle Foscam FI9818W trovate la pagina per configurare l’indirizzo IP nel menù NETWORK → IP CONFIGURATION, vedere qui sotto.

Per maggiori info cliccate qui.
