This implementation was based on Sipeed [**MaixPy**](https://github.com/sipeed/MaixPy), but it diverged from it and is now a completely independent project.



### Main features:



* Based on **kendryte-freertos-sdk**, modified to include some needed features not yet implemented and enhanced drivers support

* **MicroPython core** based on **latest release** build from [main Micropython repository](https://github.com/micropython/micropython)
Unchanged except for the *thread* support and other changes needed to work with 64-bit RISC-V.

* `BUILD.sh` script is provided to make building MicroPython firmware as easy as possible

* Running **two** independent **Micropython instances** on **two K210 cores** is supported.
Rich set of functions for data exchange between instances is provided.

* Refactored **_thread** module with many new features, based on my MicroPython for ESP32 thread module.


Rich set of threads related methods, including inter-thread notifications and messages.

* Full support for **LittleFS** as default file system on internal Flash.


LittleFS **file system image** can be prepared on host and flashed to the board.


SPIFFS is also supported (with directories support) and can be selected when building.

* Full support for Fat32 file system on **external SD Card**

* Full **file timestamp** support for LittleFS, SPIFFS and Fat32

* improved **utime** module, all time related values are handled as 64-bit values

* **SRAM** buffer is provided with content preserved after reset, accessible via `machine.mem_xxx` methods

* **uart** module, compatible with the uart module on my ESP32 port
buffered, interrupt based input with callbacks on events

* **Pin** module, compatible with the Pin module on my ESP32 port

* **i2c** module, **master** & **slave**, compatible with the i2c module on my ESP32 port
SSD1306 module provided as MicroPython frozen module

* **spi** module, **master** & **slave**, compatible with the spi module on my ESP32 port with added slave support

* **WS2812** (neopyxel) support, using **spi** module

* **Timer** and **PWM** modules

* **OneWire** & **DS18x20** module

* **ymodem** module for file transfer to/from K210 board using ymodem protocol is provided

* **uhashlib** and **ucryptolib** using K210 hardware AES are implemented

* **Display** module ported from my MicroPython for ESP32 display module
Rich set of drawing methods, direct write or **framebuffer**, *jpeg*, *bmp* and *raw* image format
Flexible fonts support (fixed width and proportional) with user fonts loadable from file (online *Font creator* provided)

* Full **network** support for **WiFi** (based on ESP8266/ESP8285) and **GSM** modules.

  * My own **ESP8266/ESP8285 firmware** is provided with enhanced features and OTA firmware update support

  * **PPPoS** support for GSM modules

  * full **SMS** support for GSM modules with collbacks on SMS receive

  * flexible and feature rich **AT command** method is provided for both WiFi and GSM modules

  * Full MicroPython **socket module** compatibility, with some additional features. FTP Server and Web Server examples are available.

  * **urequests** module (written in C) supporting all http request methods, http and https ( SSL/TLS, on WiFi, only)

  * Full featured **mqtt module** (written in C) with callbacks on all events

  * **FTP Server** and **Web Server** provided as **frozen modules**

* **usqlite3** module, data base on internal flash or SD Card, in-memory database supported

* **Boot menu**, invoked by external pin, is provided which can help solve some issues.
Options to prevent loading of *boot.py* and/or *main.py*, force format of the internal file system, load the default configuration ...

* Many **configuration options** can be configured directly from MicroPython (saved on Flash):

  * running two MicroPython instances

  * heap and stack sizes

  * using PyStack

  * default CPU frequency

  * default REPL baudrate

  * boot menu pin

  * default log level

  * using ansi colors

  * MicroPython VM divisor

* **pye**, full screen file editor (as MicroPython **frozen module**) is provided

* **MPyTerm**, serial terminal emulator specially designed for MicroPython is provided.


Included are commands to synchronize MicroPython time from PC, change the REPL baudrate, transfer files to/from MicroPython filesystem (including transferring whole directories).
Fast block file transfer is used, protected with CRC.

* **Eclipse** project files included.
To include it into Eclipse goto:
 `File->Import->General->Existing Projects into Workspace`
`Select root directory` [select *MicroPython_K210_LoBo* directory]
`Finish`.
Rebuild index
Execute `Index->Freshen All Files`.

* Many modules from my [MicroPython for ESP32](https://github.com/loboris/MicroPython_ESP32_psRAM_LoBo/wiki) port are already ported, porting some others is planned.

* _More to come soon ..._

This MicroPython port was tested on **Sipeed's MAIX** boards.


Here are some links to the distributors:



[Seed](https://www.seeedstudio.com/sipeed)


[AnalogLamb](https://www.analoglamb.com/product/sipeed-maix-bit-for-risc-v-aiiot-with-lcdcamera-development-board/)


[Banggood](https://www.banggood.com/search/sipeed.html?sbc=1) (prices to high)



It should also work on [Kendryte KD233](https://www.analoglamb.com/product/dual-core-risc-v-64bit-k210-ai-board-kendryte-kd233/), probably with some modifications, but it was not tested.
