Development tools from 8051, PIC, AVR, to ARM, displays, peripherials and virtually all for a successful development can be found in the production portfolio of company Mikroelektronika.

On the beginning there was an idea to bring on the market a user friendly environment (SW and HW) for development of applications with microcontrollers. Success and a big interest for everything, what can make development easier induced a gradual enlargement of production portfolio of company Mikroelektronika. The result is, that today company Mikroelektronika belongs to the biggest producers of development boards for the most favorite platforms like PIC, dSPIC, PIC32, AVR, STM32, Tiva C, 8051. Mikroelektronika development tools are certified as „third party tools“ or „design partner“ by many world companies like Microchip, Atmel, Texas Instruments, STM, Cypress, NXP and other.

Very interesting on the Mikroelektronika products is a comprehensive portfolio is, what means that for a given platform we´ll find software (compiler for mikroC, mikroBasic and mikroPascal), programmer, various versions of development boards, display and various peripherials. It´s worth to mention, that there are really many add-on boards available, for example: GPS, GSM, audio&video, measuring, power-supply, communication, data storage, … Some products of company Mikroelektronika also support a new graphic platform FTDI EVE. A big value for development of graphic applications are SW VisualTFT-(MIKROE-1418) and GLCD.

In our stock offer can be found for example ConnectEVE (MIKROE-1429) board with a 4,3“ display, EVEclick (MIKROE-1430), GPSClick-L10 (MIKROE-1133) and many other.

Microcontrollers, the heart of all modern electronic gadgets, are increasingly powered with sub-5V power supplies. This complicates the control of external loads powered by higher voltages. The reduced I/O supply voltage leads to increased complexity in handling high-side voltage switching. Figure 1 illustrates the conventional solution for controlling a 5V high-side switch, driven here by a 3.3V signal.

By Jon Gabay:

To do something useful, a microcontroller (MCU) must be connected to other devices. This connection is made through input/output (I/O) pins. More times than not, these days pins are multifunctional and can connect to A/Ds, D/As, linear functions (such as op amps and comparators), voltage references, and more. So for the design engineer, protecting these I/Os against potentially damaging static charges and other similar threats is of high importance.

In establishing proper protection for an MCU, engineers are finding that characteristics they have depended on for years have suddenly become less effective and they are forced to revisit problems of the past. Why? Principally, as a result of market pressure to reduce the cost of their products, semiconductor manufacturers have combined a higher level of integration with continued shrinking of process geometry, making die sizes smaller. As a result, implementing the necessary transient immunity protection to prevent malfunction due to transients on power and signal lines has become increasingly difficult.

This Design Idea demonstrates a new method of driving six LEDs with only two I/O lines from a microcontroller, and so is particularly suitable for any pin-limited chip. It uses a pair of I/O lines combined with a pair of complementary bipolar transistors. More than one LED can appear to be lit by multiplexing.

tag-connect-header-vs-icp

by Danny Mavromatis:

There are a lot of little details you need to think about when taking a project from PoC (proof-of-concept) to production. Most projects today have some form of onboard microprocessor and require you to flash your custom bootloader and/or program code onto it at some point. There are many ways this can be accomplished but the most common method is using an ICP (in-circuit programmer) connected to a 6-pin ICP header somewhere on the PCB. […]

Tag-Connect! I can’t remember exactly how I found out about this neat little connector, but I’ve been using it for a while and it’s actually very useful in a production environment. They provide the footprint for many of the popular PCB design programs so placing it is very straight forward. Pretty much just swap out the traditional header for the new tiny Tag-Connect version and you’re pretty much done.

This is a 8 channel relay interface board using ULN2803. All the relays are opto-isolated using optocouplers and can be controlled directly using a microcontroller of any kind (Arduino , 8051, AVR, PIC, DSP, ARM, MSP430, TTL logic) or a PC.

It’s easy to manufacture and have three pin screw terminals for easy connectivity.

Dynamic Near Field Communication tag, a new wireless technology that connects phones with MCU after wifi and Bluetooth, is your optimized NFC solution.

We are proud to bring about the Dynamic Near Field Communication tag (DNFC tag), an invention that who especially tech nerds and DIY lovers have been expected for long. It greatly outstands among traditional read-only NFC tags because it’s readable and rewritable and it can communicate with various platforms, to name several most popular: Arduino, Raspberry Pi, Leaf Maple stm32 and some more. It owns a high level of dexterity, thus making it efficient, easy to execute and user-friendly.

The clue is in the name: Near Field Communication. It allows NFC portable devices to establish peer-to-peer radio communications, delivering data from one to another by touching them or putting them very close together. Basically, when you get your phone (if it has NFC as a feature) close to something equipped with NFC – like a tag – it invokes an action on your device.

Raj @ embedded-lab.com build a programmable digital timer. He writes:

Digital timer switches are used to control the operation of electrical devices based on a programmed schedule. This project describes a programmable digital timer based on the PIC16F628A microcontroller that can be programmed to schedule the on and off operation of an electrical appliance. The appliance is controlled through a relay switch. This timer switch allows you to set both on and off time. That means, you can program when do you want to turn the device on and for how long you want it to be remained on. The maximum time interval that you can set for on and off operation is 99 hours and 59 minutes. The project provides an interactive user interface using a 16×2 character LCD along with 4 push buttons.

MikroElektronika today announced that May 6, 2014 marks the 10th anniversary since it started developing compilers for Embedded programming – mikroC, mikroPascal and mikroBasic. The company will celebrate the occasion with a month long campaign that will include exclusive content, discounts and weekly full compiler license giveaways.

The successful release of mikroPascal for PIC in 2004 spawned an extensive product line that today has 18 compilers for six popular MCU architectures (ARM, PIC, dsPIC/PIC32, 8051 and AVR) that had a significant impact on the embedded electronics industry.
