Iteaduino Plus is an open source ARM development board, which is based on Allwinner A10/A20 SoC, small size, hacker friendly, extendable and very low-cost.

For details of the hardware, you can refer to http://imall.iteadstudio.com/iteaduino-plus-a10.html/ and http://imall.iteadstudio.com/iteaduino-plus-a20.html/

Iteaduino Plus SDK is customized for Iteaduino Plus and offers junior developers with underlying hardware operation interfaces. It can simplify the hardware operation, which is a way for software engineers who are not familiar with the underlying hardware and junior developers to know about "Code World" and "Physical World"; it can also work as a rapid prototyping development tool.

The operating functions similar to Arduino offered by the SDK make it easier for those who have some understanding of Arduino. Moreover, with the SDK, Python users can operate the underlying hardware more easily.

The SDK can also be applied in others development boards which adopt the same chip (Allwinner A10/A20) such pcDuino, Marsboard, Cubieboard, etc.

• Support for simple GPIO operation
• Support for GPIO 8-bit / 16-bit bus operations
• Support for simple UART operations
• Support for simple upper-layer time operation functions
• Support for IIC bus operations
• Support for SPI bus operations
• Support for SSD1306-based IIC interfaced OLED screen operations
• Support for LCD1602 LCD in 4-bit mode
• More libraries are being developed

Up to 9th, Apr., 2014, the SDK has been added with support for GPIO, TWI ,SPI and UART and supplied with libraries of LCD1602, SSD1306 OLED, etc. With various API's at bus interface, users can easily operate UART,SPI and IIC devices; while with API's on the modules, users can use the functions in the library directly to control OLED screen for display and the same to LCD1602.

• Platform :Allwinner A10/A20 SoC
• Kernel verson: linux-sunxi-3.4 https://github.com/linux-sunxi/linux-sunxi
• Kernel make configure file:https://github.com/iteadsw/SDK/blob/master/tools/iteadunio_plus_a10_defconfig and https://github.com/iteadsw/SDK/blob/master/tools/iteadunio_plus_a20_defconfig
• FEX file:https://github.com/iteadsw/SDK/blob/master/tools/iteaduino_plus_a10.fex and https://github.com/iteadsw/SDK/blob/master/tools/iteaduino_plus_a20.fex

Users of Iteaduino Plus A10/A20 can directly download and install the latest system img and SDK; users of other platforms are recommended to use make configure provided to compile 3.4 kernel and apply the fex file offered.

Python users need to know the specific installation locations of the following dynamic libraries when they use the SDK:

• libiteadc.so(core c language dynamic library):/usr/lib, /usr/local/lib
• libiteadcpp.so(core c++ dynamic library):/usr/lib, /usr/local/lib
• libiteadmodule.so(all the c++ modules library):/usr/lib, /usr/local/lib

Take debian as an example:

1. git clone https://github.com/iteadsw/SDK.git
2. cd SDK
3. make
4. make install

Note: We assume that you have installed the build-essential package in your debian system.

For details, please find in project wiki. With more and more hardware that it supports, wiki will also be updated accordingly.

• Provide more API for user's application
• Support more hardware platform
