rfduino lcd panel library supplier

This is the RFduino Dev Kit, a great duo of products in one box to help you get you started with and teach you the basics of RFduino. Inside this kit you will find two RFduino boards, the DIP mainboard and the USB shield. When attached, these two boards will be able to connect to the USB port on your computer and get your code through the Arduino IDE onto the RFduino DIP board.
The RFduino is a Bluetooth 4.0 Low Energy BLE RF Module with Built-In ARM Cortex-M0 and RFD22301 SMT module for rapid development and prototyping projects. The RFduino operates at 3V and 18mA (4uA ULP), transmits of a 2.4 GHz band, and offers 128kb of flash memory with 8kb of ram. Via a Bluetooth connection with your iOS device you even run a series of free apps to control various shields through the RFduino DIP board. Meanwhile, on-board the RFduino USB Shield is a 3.3V regulator which can be used to supply power to the RFduino DIP module as well as other shields and possibly the rest of your circuit.
With this kit you won"t need to worry about buying the USB shield separately from the RFduino DIP, it"s all in one box and ready to be used right away!

When you upload the first code, the RFduino will send the number 1 infinitely every 3 seconds. You will be able to view this with your phone using a BLE serial app. You can find an example app that you can use in this link.
When you upload the second code, the RFduino will display the first byte of any incoming data on the arduino serial monitor. For instance, if your send 34 from the app, 3 will be displayed on the serial monitor.
There are many things that you can do with the RFduino. I will be posting a full tutorial of a project i am working on with it. Meanwhile, you can check out the full tutorial of this article here.

Arduino UNO model of the entire series was in maximum demand. Keeping intact the technology of Arduino UNO, a new stand-alone micro-controller board has been constructed which is named as RFduino. This platform is highly advance and undoubtedly unique. The primary feature of RFduino is its exclusively small size which fits into any kind of project. Also this multiplatform controller is highly cost efficient. Hence, it is a perfect package of a miniature, high efficiency and low price tag multi-processor.
RFduino is a wireless enabled micro-controller which induces compatible communication with any Bluetooth 4.0 in smartphones or tablets. But Android operating system was lagging behind in the nature of interaction with various wireless networks. The reason behind it was lesser number of devices supported Bluetooth 4.0 LE. After the launching of the new RFduino board, it only supported the iPhone 4 and 5 series for Bluetooth 4.0 LE. But now this advance bluetooth technology is available in Android operating system.
RFduino – Read analog sensor is used to display data from the analog sensor into your iPhone. This is done with the help of bluetooth technology between RFduino and iPhone. By connecting a single sensor to the GPIO pin and inducing 5V power into the circuit, this unbelievable technology can be incorporated.
RFduino with a 6 Axis accelerometer helps communication of your smartphones with the various pre-installed sensors. The RFduino communicates easily with the accelerometer or gyroscope and transfers output data directly into the computer via USB shield.?
RFduino Temperature app is used to create a sensor application for reading temperature on your iPhone. This is initiated by reading the data from a TMP36 temperature sensor through GPIO pins. While sending data the signaling LED turns on.
RFduino Servo app build on your iPhone allows you to control all the four standard servos which are interfaced with a servo shield and is controlled through RFduino.
RFduino + adafruit ST7735 1.8” TFT displayhelp you to display images. ST7735 1.8” TFT displays several images using GPIO pins of RFduino from the adafruit ST7735 library.
Twitter RFduino App enables you to send messages automatically into the twitter account. Bluetooth allows you to send messages within a small range. But Twitter RFduino App will allow you to send messages via low energy bluetooth 4.0 initiating small application of internet.
Quadcopterinstalled in various flying devices, is controlled by RFduino micro-controller. Besides it also helps the Quadcopter to connect with the ground by sending data into the smartphone.
You can avail various options in term of devices to build a robot. Some devices come with complete manual and kits. Some are stand-alone devices which have to be accessorized before configuring it into any kind of project. Building a robot requires complete kits, scratches fro 3D printer and many other robotic parts. If you are absolutely comfortable with Arduino devices, then RFduino will be the ultimate choice for devising such robots. The plus points of this micro-controller are, it fits your budget and provides high-efficiency performance with its Bluetooth 4.0 LTE. With les than $20 you can avail this extraordinary device and construct your own project.

Anyway, I found the RFduino and ordered one. I managed to get it all working within 20 minutes so here are my initial thoughts and findings. You will need an iOS device (4S onwards have BLE) to get what I have in this blog working.I will cover how to get a custom iOS and Android app working with this shortly.
First thing to note is the size of it. It is very small considering that you have both the micro controller and BLE circuitry all in one tiny package. The picture below shows the USB programmer and the RFduino on a dev board. If you were to drop the RFduino directly onto your own PCB it would only take up less than 20x20mm! Considering you are also getting an ARM Cortex M0 that can be programmed like an Arduino it really does become quite useful.
The above only costs £30 from RS, the RFduino PCB singular is £10 which does make this quite a cheap package if you are wanting to start experimenting with BLE.
Setting up the RFduino is mostly a simple task if you have used any similar hardware etc but there is also plenty of information at RFduino.com for any in depth help. I will just glide over it to give a brief synopsis of what is needed. Feel free to message me with any questions if you like!
2. Download the RFduino zip package from here. Unzip and place in the following directory: programFiles/Arduino/Hardware/arduino (there should be two folders in the directory already called ‘sam’ and ‘avr’ to make sure you are in the right place). On a mac go to applications and right click the Arduino application, select show ‘show package contents’. Then drop the file in: contents/resources/java/hardware/arduino.This gives the Arduino IDE the information to program the RFduino.
3. Open the RFduino folder and then the libraries folder inside it. Copy the RFduinoBLE folder and place it in the Arduino libraries folder (this will be found at the same level as the hardware folder). This will give us all of the RFduino example code.
Now plug in your RFduino. Open the Arduino IDE and load the temperature sketch from the RFduino section of the examples section. I like chose this one because it involves no other hardware.Select ‘RFduino’ as your board and finally set your COM port correctly, usually this is automatic on Windows (normally tty.usbserial on a mac). Both parts are pictured below.
Now upload the sketch to the RFduino. ‘Success’ should be displayed in orange in the console at the bottom of the IDE if all has gone well. If you get an error, check that your files are in the right place in the hardware and libraries directories. You may have noticed nothing seems to be acting any different.
Get your iOS device out and download the RFduino temperature sample app from the App Store. https://itunes.apple.com/us/app/rfduino-temperature/id668832196?mt=8
Turn Bluetooth on in settings on your iOS device and load the app. You should now see a list view with one entry showing your RFduino. Press the RFduino entry in the list and it will change view to show you the current temperature from the RFduino board on your iPhone screen. Easy as that.
I would now look at the rest of the examples and see what you can make. RFduino have been generous enough to supply the source Xcode projects for the iPhone apps too in the RFduino folder. There are also more finished sample apps on the App Store if you search for RFduino.
Below is a screenshot of the current example sketches from RFduino. As you can see there is a wide selection, from servo control, proximity, to iBeacons.

The library is included in the official Arduino library manger and the optimum way to install it is using the library manager which can be opened by the manage libraries option in Arduino IDE.
NO_BUFFER , Text only no buffer , relatively light weight. Turns LCD into simple character LCD(216 characters). Default font only. Bitmaps can still be written directly to screen but no graphics possible.
It is also possible for user to change LCD bias , Temperature coefficient, frame rate and power control but this must be done by changing defines in header file. Choose lower frame rate for lower power, and choose higher frame rate to improve LCD contrast and minimize flicker. See Data sheet for range of values
