Hello
I just got the Sipeed MaixDock boards and I have flashed your firmware MicroPython 1.11.11 (76c3fd1-dirty) built on 2019-08-07; Sipeed_board with Kendryte-K210. The firmware with LittleFS (kpfpkg)
I am able to play with it on the terminal window.
Is there a work flow to integrate it with an IDE other than copy pasting code on to terminal.
If I want to write a JPEG file (from the computer) to the flash and read the image on maixdock board for displaying on the LCD. How do I go about it, can you point to any samples or equivalent tutorials
Thanks

| gps.read_parse('GNRMC') time tuple |

When i set my NEO-M8N to 5Hz gps update, i don't get the "decimal" second when using "gps.read_parse('GNRMC')"
See data below. It says ", 1, 349" on every time tuple instead of the decimal seconds during second 28. This makes a problem when differensing the gps positions during a second.
Anyone have a solution for this ??

Hi All, im new to all the ESP32 and electronics. I have an ESP32 dev board which when its connected via a tablet or Laptop for its power then it all works fine and the WiFi is visable. but when i power it usinig a 3.3v or 5v supply or even if i connect it onto a breadboard with a breadboard power Adapter for this device then the WiFi is never visable.
hopefully someone can explain why this might be Happening.
thanks

Hello,
I'm using LILYGO TTGO T-Display ESP32 with ST7789V LCD on Arduino.
it's works well but i would like to use it with micropython.
everything works well with esp32_all, but not the display
does anyone know how to make it working ?
my code :
Code: import display
tft = display.TFT()
tft.init(tft.ST7789,width=135,height=240,mosi=19,clk=18,cs=5,dc=16,miso=19,rst_pin=23,backl_pin=4,backl_on=1)
tft.rect(10,10,100,100,tft.RED,tft.BLUE)
backlight is on, but it's all
thanks to community

Hi,
I have just purchased a Maix Bit and Maix Dock SiPeed Maix board from Seeed. They talk a lot about MaixPy which seems very familiar to someone who has worked with the Loboris ESP32 micropython port. Is your K210 port different from what these guys are doing, or are they associated in some way?
Just trying to figure out which way I want to go when the boards arrive.
Thanks, Duane

Hello to you
I don't remember how I ended up on this forum, however I assume you are the one who is mentioned in ESP32 github section for providing several fixes.
Can you let me know what is the frame rate that you are able to achieve with the Sipeed K210 board and the OV2640 camera. I am told by the developer that they are unable to get 30FPS in VGA mode. I read on ESP32 camera board fixes, that if the clock is properly configure OV2640 allows 30FPS in VGA.
Can you let me know whether you achieved 30FPS with OV2640 or any other camera module using Kendryte.

Hi there,
very new to micropython, but enjoying it so far. I am a bit of a novice so this may be where my issue lay 
I have a script that produces the error ...
assertion "ATB_GET_KIND(block) == AT_HEAD" failed: file "/home/LoBo2_Razno/ESP32/MicroPython/MicroPython_ESP32_psRAM_LoBo/MicroPython_BUILD/components/micropython/py/gc.c", line 596, function: gc_free
abort() was called at PC 0x40121da3 on core 1
I have seen this mentioned elsewhere on the forum, wrt ports, but none of these discussions help with my current issue.
before posting here I ran the code through flake8 and pylint (ignoring some capitalization formatting etc), to make sure I was somewhat pythonic and free of some issues.
This is code for a flow meter that squirts it's measurements into influxdb, it has 2 threads that I start, one to manage a queue, and the other to keep an eye on the network.
It is no where near complete, and remember I am a novice ... but happy to take pointers to making it better.

EDIT: This is running on an esp32 Cam module, but have tested same code on a esp32 Wroom 32, with same results as described above
EDIT2: Seems I have narrowed it down to urequests(), as soon as it fires in the queueThread, that causes the core dump, after a few seconds/minutes ... if I comment it out, the code will run fine for hours (all I have tested)

I have been unable to run the calibration of a touch screen, ILI9341 with XPT2046 touch controller.
Screen initialised:
from machine import SPI,Pin
import display
import tpcalib
tft = display.TFT()
tft.init(tft.ILI9341, width=240, height=320, miso=12,mosi=13,clk=14,cs=15,dc=26, rst_pin=27,tcs=25,hastouch=tft.TOUCH_XPT, bgr=True)
def touch_cal():
tpc = tpcalib.Calibrate(tft)
#dosave = True
tp_type = tft.TOUCH_XPT
tpc.tpcalib(tp_type)
on calling touch_cal() the screen is displayed, but is unresponsive to touch.
note: tpc.tpcalib(tt_type,dosave) gives 2 errors should be tp_type and only 1 variable required
I have tested the touch functioality using a driver derived from : http://www.ars-informatica.ca/eclectic/x...libration/
.
Any help appreciated

I’m working on an ESP32 camera project (Arduino IDE) that I would like bring over to a K210 based board for performance reasons.
Here’s a quick video demo of what I have at the moment: https://youtu.be/232PdOVPyPg
At the moment I have a web page hosted on the ESP32. Commands and the video stream are over websockets. The cursor overlay uses the IDF gfx library.
How much of this is possible with the current MP port for the K210? I have a Sipeed M1 and the Maixduino.
