Have to say, the fine-divided market of electronic products is also very worth exploring. According to statistics, now more manufacturers are willing to use Correspondents to develop electronic products related to the field of education, such as the building blocks that I am young. Now it can be transformed into an electronic building block that can be developed, more fun, more fun, and more fun, today gives engineers, college students, friends, and love electronics, you can do a wild electronic. Toy - Mcookie kit.
McOokie202 kit
The Mcookie Kit is a vibrant educational product launched by Microduino, compatible with the current popular Arduino functional hardware module, and a set of toy kits that can be combined with Lego splicing categories. The pavilion network is the McOokie202 in the Mcookie series, the price is 1399RMB, you can buy it on Taobao.
The Mcookie202 box is very exquisite, and the layers of internal products are distinguished. It is very easy to familiarize with each module for general engineers.
Mcookie202 provides 8 modules, distinguished red core control modules * 1, yellow function module * 3, blue communication module * 1 and cyan extension modules * 3.
In addition, Mcookie 202 also provides various types of sensors, functional peripherals, extended interface lines, battery modules, where the sensor and function peripheral modules contain our common IR transceivers, LED, MIC, buzzers, temperature sensitive resistors, Touch switch, servo motor, speaker, remote control, etc., enough player DIY and toss for a while.
Core module
The Mcookie202's main controller is the AVR series Atmega328 8-bit microcontroller, which belongs to the same microcontroller with the Arduino UNO development board. It is conceivable that it is not a problem with resources such as Ide tools, peripheral modules. The red core module is essentially a minimum system based on Atemga328 MCU. All pins of the MCU are extracted by POGO, and can be connected to other functional modules, communication modules, extended modules. The POGO pin is a highlight of the Mcookie kit. It is different from the pin connector we can see, and POGO is a spring-nature connector, which is convenient to connect, especially with the magnets on both sides of the plate, can be seamlessly connected to other modules, convenient Assembly disassembly, in structured design belongs to a major breakthrough, and product design engineers in this regard can refer to the next similar design.
It is a bit unfortunately that each thimble is not indicated by the screen of the signal on the core board, so it is necessary to understand the definition of each signal feet. It is necessary to go to the official look, as shown below - from the front direction (MCU is above) The pin definition table starting in the direction of the U-shaped pattern is shown below.
If you look back from the back, you should pay special attention to custom signal control feet when programming.
functional module
The Mcookie 202 includes 3 functional modules, with the audio decoding module, which includes a complete audio output circuit, in the design of the module, realizes the ATMEGA328 MCU communication on the red core board by level conversion IC, and the circuit is clear Audio decoding chip, audio amplifier is output to the headset or speaker terminal.
The circuit of the MicroSD card is very simple and connected to a level conversion chip.
The RTC module uses the I2C interface and core module communication, board EEPROM, PCF8563 calendar clock chip, and power-down can still be run through the button battery.
Expansion module
There are three extended modules of the Mcookie 202, which are OLED modules, LED array display modules, sensor hub modules.
The OLED module uses an I2C interface, onboard 128 * 64-resolution screen of 0.96 inches.
Here, there is also a very interesting design, see other modules of the Mcookie kit, whether it is the core board, microcontroller function board, etc., and on the OLED screen board, only the most basic 4, power, land, sda, scl, why? Very simple, other modules can be used in the laminate, and as a display, if you want to use, you can need to put it on the top, without the need for a stack, of course, for the combined diversity, the OLED display module is also equipped with an interface. The I2C interface can be implemented by a flying line, and it is still very comprehensive in design.
The LED array is displayed in parallel to 6 RGB LEDs, and 6 LEDs are controlled by the A0 pin, which can be configured by one I / O port, which can be controlled, completed data reception and decoding, where The tricho colors of each pixel point of the LED can achieve a 256-level brightness display to complete the full color display of 16777,216 colors.
The sensor hub module is to divide the atmega328 microcontroller on the core board into an interface through the POGO bombing pin. This is nothing more.
Communication module
The Mcookie202 kit also includes a unique communication module low-power Bluetooth module, the core is based on the Bluetooth single-chip SOC of Ti CC2541, communicating with microcontrollers through serial port, direct drive, IBeacon mode. The support direct drive is mainly integrated in CC2541, integrated an enhanced 8051 MCU, which can work directly to other peripheral modules, of course, in the Mcookie suite, this part of the function is reserved, after all, there is no additional to the signal pin of CC2541.
There are also many sensor modules in the Mcookie202 kit, which is not alone. Interested in understanding the official understanding of Microdunio, I believe that everyone will wait to pay attention to how this suite is playing?
learn! Development! DIY!
First of all, here is a cold water, the Mcookie kit is not an unpacking box, and it still needs to be done in advance.
We all know that the Arduino development board can use the official Provision of Arduino IDE tool, and Mcookie is of course no exception, but the most convenient is the use of the ARDUINO IDE provided by the US officially provided, the reason is not to integrate the corresponding library. And drive.
This IDE tool can be downloaded in Microduino official website, or it can be taken in the MicroSD card in the suite.
In addition, Mcookie also supports graphical programming environments Mixly, Mixly is an open source graphic programming environment for supporting Mcookie visualization, and jointly developed by Posted by Chuangke Education and Microduino, the University of Beijing.
Mcookie also supports Scratch. Scratch is a simple programming tool for juvenile design and development by the MIT (MIT), which is actually similar to Mixly, and does not introduce it.
In addition to the IDE tool, there is also a non-serial tool, and Mcookie provides a block battery board and built-in USB serial port function, so that the application you built will be able to move the mobile display after the burning program.
Next, the Arduino IDE tool will be developed. From the development tools provided by installing the US Department, you can see a considerable McOokie-based routine, which can be used directly.
The following applications require power supply based on the battery module.
The core module + OLED display module can realize the display of the content.
With the 27PIN POGO ball needle, you can achieve different forms, with music high splashing wood, you can say that fun is endless.
The core module + RTC module + OLED can form a year of life clock.
The core module + LED module implements the control of the RGB LED.
Another application of more modules, core module + audio module + OLED module + sensor hub module + microSD card module + speaker + infrared receiving sensor + remote control, can achieve a small set of infrared remote control, is it very slippery.
Some of the above applications are based on the application of existing basic module into makeshift, more users can be composed of a wide variety of applications, such as alarms, music boxes, mug by mCookie202 kit + sensor module equipped, Fans, watches, motor sectors, etc. It can be played with the playable content. It can be empty, how big is the heart, how big is the stage.
summary
McOokie202 kits launched by Microduino have compact, stacking, open, compatible high characteristics, plus open source hardware circuit design, with Arduino compatible programming development environment, suitable for teenagers and beginners graphical programming environment Mixly and Scratch, mCookie uniform interface specification, matched with rich peripheral modules can be convenient and flexible for quick connection and expansion in line with other Microduino / mCookie interface specification module, sensor, composed of a variety of interesting rich applications, interested friends may wish to purchase a set of their own, whether it is learning, development or DIY, I believe can have a very good experience.
