Подключение cиловой нагрузки к микроконтроллеру.
Подключение cиловой нагрузки к микроконтроллеру. Микроконтроллеры предназначены для обработки данных и для управления внешними устройствами. Электрические цепи, в которых используются микроконтроллеры, иногда требуют для управления высокое напряжение или большие токи. Примерами таких устройств явля...

[AVR] Multi-function shield for Arduino UNO
Hello, friends. Take a look at this great multi-functional shield for the Arduino UNO R3. This shield can be inserted into the Arduino header and requires no additional power supply. Some shields have to long pins under 7-segment led tube and may contact USB connector. This will produce garbage on t...

Re: [AVR] How to drive 4-Digit 7-Segment LED Display (Arduin
Hi, All. The simple sketch that displays digits is not usefull and can only be used for learning purposes. It is much interesting to concentrate on some real task that could be useful in your project. The starting point for any project is to be clear on the needs it is addressing. Now we will demons...

Re: [AVR] How to drive 4-Digit 7-Segment LED Display (Arduin
In the previous post, we discussed 4-digit 7-segment display. This topic is so important we felt it deserved additional attention, because almost any DIY-project needs OUTPUT device. We will inroduce new effective concept based on interrupts and timers . The code will be transparent for the main app...

[AVR] How to drive 4-Digit 7-Segment LED Display (Arduino)
How to connect and drive 4-Digit 7-Segment LED Display with Ardino UNO. In previous topic we discussed how to drive a single 7-segment LED Display . I think it was simple, but it requires lots of wires. Usually we need to display big numbers that contain multiple digits. For this purpose there are ...

[AVR] How to connect and drive 7 Segment LED with Arduino
Hello. A seven-segment display is a device for displaying decimal numerals. Such LED-displays are widely used in digital clocks and other electronic devices for displaying numerical information. The 7-segment display is a simple device. It is actually composed of seven elements and a dot (8 LEDs, Li...

Re: [STM] Tutorial: Getting started with STM32F3 Discovery b
Lesson #3. This lesson shows how to use System Timers to control the LED of an STM32 microcontroller. System Timer is implemented as an interrupt handler. SysTick_Handler is called every N-ticks on an STM32 Discovery Board. Cortex-M3 (M4) has a wide variaty of timers that generates different events....

Re: [STM] Tutorial: Getting started with STM32F3 Discovery b
Lesson #2. In this tutorial we will devolop firmware for a STM32F303 board. This program polls the state of the user pusshbutton. When the button is pressed all LEDs are switched on. In the other case the LEDs are turned off. User pushbutton is connected to Pin_0 on Port_A. There is a push-pull resi...
