Introduction : MicroPython examples and tools for Portenta from Ayan Biswas

[ayan-biswas0412]

Who am I and my background of working ?

I am Ayan Biswas , a undergrad at Jadavpur University , Kolkata ,India majoring in Electronics and Telecommunication Engineering .
As per my course curricula I have done several arduino projects using Arduino uno , Raspberry Pie, jetson Nano ranging from opencv based trafiic signal detection car , basic line follower , bluetooth module based car and a smart door lock system using NFC cards etc. My comfortable programming languages are C/C++ , pyhton and also i posses knowledge of maintaining database (MySQL, POSTGREsql etc )and i also comfortable in web developing .

What I can do in GSOC '20 for Arduino ?

I can work in the areas of writing MicroPython examples and tools for Portenta again as my major subject is fully related to this project so i want to do this as i think i am capable for this ,

Reply me if you are interested and i will upload my complete proposal for GSOC 2020 shortly.

I have written this short code i don't know is this the right start for your project or not @alranel Please guide me about that what kind of work is really needed for Portenta and what type of project proposal do you expect from me such that i can turn in a right direction for GSOC'20 .

This program is about the Driver Code for Adafruit neo pixels (WS2812 chip)

# driver for Adafruit neo pixels (WS2812 chip)
import pyb

class NeoPixel:
    def __init__(self, spi, n):
        spi.init(spi.MASTER, baudrate=2625000)
        spi.send(0)
        self.spi = spi
        self.buf = bytearray(9 * n + 1)
        self.clear()

    def __len__(self):
        return (len(self.buf) - 1) // 9

    def __setitem__(self, idx, val):
        idx *= 9
        self.fillword(idx, val[1]) # green
        self.fillword(idx + 3, val[0]) # red
        self.fillword(idx + 6, val[2]) # blue

    def clear(self):
        for i in range(len(self)):
            self[i] = (0, 0, 0)

    def send(self):
        self.spi.send(self.buf)

    def fillword(self, idx, val):
        expval = 0
        for i in range(8):
            expval <<= 3
            if val & 0x80:
                expval |= 0b110
            else:
                expval |= 0b100
            val <<= 1
        self.buf[idx] = expval >> 16
        self.buf[idx + 1] = expval >> 8
        self.buf[idx + 2] = expval

# creating the  driver on SPI(1) with 8 pixels

ws = NeoPixel(pyb.SPI(1), 8)

# scroll one to a  white pixel
for i in range(48):
    ws.clear()
    ws[i % len(ws)] = (64, 64, 64)
    ws.send()
    pyb.delay(50)

# turn all the  pixels off
ws.clear()
ws.send()

Also I am quite new in this open source project environment and i have worked previously in Girsscript Summer of Code (GsSOC 2020) as my first open source project that was also an Arduino UNO Based Water management System .

Now i will be highly obliged if i can contribute for the new Portenta

@alranel Can you please guide that what things must be included in my final GSoC '20 project proposal , actually i want to know that what things you want from me for this particular idea mentioned #99
Please guide me as early as possible .

[ayan-biswas0412]

I have shared my draft proposal through my Dashboard of GSoC'20 Please mention in the comment of the draft if anything modification is required @alranel

@alranel I have updated my project timeframe in my Project Proposal in the Schedule of Deliverables section for this project as per the new timeframe guidelines received from Google on Mar 24, 2020, 11:29 AM (IST)

[ayan-biswas0412]

My Contribution relevant to this project Check #47
I have added a Micropython example for Sweep of Servo , Take it as my very initial contribution to the Portenta Project.

[ayan-biswas0412]

My Contribution relevant to this project Check #53
I have added a Micropython example for controlling of Servo with a potentiometer , Take it as my second contribution to the Portenta Project.
