**Let's Sipeed up, Maximize AI's power!**
**MaixPy, makes AIOT easier!**
Maixpy is designed to make AIOT programming easier, based on the [Micropython](http://www.micropython.org) syntax, running on a very powerful embedded AIOT chip [K210](https://kendryte.com).
There are many things you can do with MaixPy, please refer to [here](https://maixpy.sipeed.com/en/others/what_maix_do.html)
> K210 brief:
> * Image Recognition with hardware AI acceleration
> * Dual core with FPU
> * 8MB(6MB+2MB) RAM
> * 16MB external Flash
> * Max 800MHz CPU freq (see the dev board in detail, usually 400MHz)
> * Microphone array(8 mics)
> * Hardware AES SHA256
> * FPIOA (Periphrals can map to any pins)
> * Peripherals: I2C, SPI, I2S, WDT, TIMER, RTC, UART, GPIO etc.
## Simple code
Find I2C devices:
```python
from machine import I2C
i2c = I2C(I2C.I2C0, freq=100000, scl=28, sda=29)
devices = i2c.scan()
print(devices)
```
Take picture:
```python
import sensor
import image
import lcd
lcd.init()
sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QVGA)
sensor.run(1)
while True:
img=sensor.snapshot()
lcd.display(img)
```
Use AI model to recognize object:
```python
import KPU as kpu
import sensor
sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QVGA)
sensor.set_windowing((224, 224))
model = kpu.load("/sd/mobilenet.kmodel") # load model
while(True):
img = sensor.snapshot() # take picture by camera
out = kpu.forward(task, img)[:] # inference, get one-hot output
print(max(out)) # print max probability object ID
```

## Other: As C SDK for C developers
In addition to the source code of the `MaixPy` project, since `MaixPy` exists as a component, it can be configured to not participate in compilation, so this repository can also be developed as `C SDK`. For the usage details, see [Building Documentation](build.md), which can be started by compiling and downloading `projects/hello_world`.
The compilation process is briefly as follows:
```
wget http://dl.cdn.sipeed.com/kendryte-toolchain-ubuntu-amd64-8.2.0-20190409.tar.xz
sudo tar -Jxvf kendryte-toolchain-ubuntu-amd64-8.2.0-20190409.tar.xz -C /opt
cd projects/hello_world
python3 project.py menuconfig
python3 project.py build
python3 project.py flash -B dan -b 1500000 -p /dev/ttyUSB0 -t
```
