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

Posted on 23/09/2018 by wp_2592768

–

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

Posted on 23/09/2018 by wp_2592768

–

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

Posted on 30/07/2018 by wp_2592768

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.

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.
