Let's Sipeed up, Maximize AI's power!

MaixPy, makes AIOT easier!

Maixpy is designed to make AIOT programming easier, based on the Micropython syntax, running on a very powerful embedded AIOT chip K210.

There are many things you can do with MaixPy, please refer to here

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:

from machine import I2C

i2c = I2C(I2C.I2C0, freq=100000, scl=28, sda=29)
devices = i2c.scan()
print(devices)

Take picture:

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:

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, 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
