Re: Screenshot of LCR160CR ?

It seems PPM image file format is simpler than BMP, easier to code even in MicroPython. For example :
PPM image from scratch in Python 3
nicholasRutherford/ppmFile.py
MANDELBROT FRACTAL IMAGE OUTPUT TO PPM FILE (PYTHON RECIPE)

Re: Screenshot of LCR160CR ?

Good idea to convert RGB565 to bmp. I'll look at OpenMV MicroPython source code to try to get MicroPython code to save in BMP format (in the image module) : http://docs.openmv.io/library/omv.image.html#image.image.save But I guess it is implemented in C/C++ : https://github.com/openmv/openmv/tree/ma...

See

Code: Select all

LCD160CR.screen_dump(buf, x=0, y=0, w=None, h=None)
Note that buf holds pixels in RGB565 format.
Thanks.
So the buffer could be saved to a binary file in RGB565 format.
Then I can copy the RGB565 files to a PC and use a PC tool (imagemagic, ffmpeg, etc) to convert the format to PNG, etc.

Tried compiling and flashing the version1 branch:
MicroPython v1.9.2-34-gd64154c73 on 2017-09-01; micro:bit with nRF51822
Could you post the firmware file (.hex) for MicroPython v1.9.2 on BBC Micro:bit ? It is useful to flash it with uflash.

Screenshot of LCR160CR ?

What about screenshot of LCR160CR being saved to picture file (.jpeg, .png., etc) on internal flash or external flash (microSD) ? Has anybody implemented this feature ? Maybe using the framebuffer , converting the frame buffer format to a picture format. Yes, I know that the LCD160 module can show j...

Re: Drivers for Waveshare 2.13inch E-Ink display

It would be useful to have a pure MicroPython driver compatible with Pyboard, WiPy 1, ESP8266, ESP32 and Pycom boards (WiPy 2/3, LoPy, etc). Anybody is making this type of driver ?

Re: [ANN] Packaging and deployment docs

Thanks for the detailed documentation, pfalcon. I'm still very impressed of how much computing power, performance, billions of man-hours of open-source software you can have in a 2 or 3€ device. A so long way since my ZX81. I've also started programming with ZX-81 Sinclair computers. Microcontroller...

Re: Bluetooth SnekTek Board

Nice to see more MicroPython products, now targetting users with less hardware skill ! Suggestions : - explain in the site which Wireless connectivity (Bluetooth, WiFi ?) is used by each product (some products show BLE, but others don't); - list the specifications (which microcontroller, sensor name...

Re: repl on the BBC:Microbit

The internal flash space is very limited, depending on the size of the MicroPython firmware installed. Like 15-30 KB, for example.
