New firmware release v1.14.0.b1 (Dual core support and CAN bus)

[peekay123]

Updated a LoPy (1.0) that was running a simple rainbow animation of a set of 8 WS2812b neopixels. On previous versions, the animation tended to be choppy at times. After upgrading to v1.14.0.b1 with dual processor support, the animation is SMOOTH! Nice!

Any plans to update documentation on using the CLI version of the updater tool? Maybe I'm just using it wrong:

.\pycom-fwtool-cli.exe -f "C:\Users\xxxx\Code\Pycom\pycom-microp
ython-sigfox\esp32\build\LOPY_915\release\appimg.bin" -p COM3 --pypic flash
Connecting.....

Stub running...
Changing baud rate to 115200
Changed.
Exception: Timed out waiting for packet content, on line 204

Thanks!

For lopower consideration, to run only on one core, what we have to configure in the build ?

Still persists the pic build issue

@colateral said in New firmware release v1.14.0.b1 (Dual core support and CAN bus):

self.serial = serial.Serial(port, baudrate=115200, bytesize=serial.FIVEBITS, timeout=0.25)

Can you please try to replace above line in tools/pypic.py with:

self.serial = serial.Serial(port, baudrate=115200, bytesize=serial.FIVEBITS, timeout=0.25 exclusive=True)

P.S. I made a small edit after I posted this originally.

release v1.14.0.b1 is crashing during boot process on one of my LoPy4 (no software loaded). At least two other LoPy4 are working with new release v1.14.0.b2.
With v1.9.2.b2 (original hardware on delivery) the failed LoPy4 is working.

I will provide documentation for the CLI tool with the next release as I'm currently re-designing the command line parameters.

If you want to flash your board after building it from source please use make flash instead.

When framebuf will be updated to support all formats?
now it cover MVLSB, RGB565, GS4_HMSB
but official micropython cover MVLSB, RGB565, GS2_HMSB, GS4_HMSB, GS8, MHLSB, MHMSB

[livius]

if someone is interested i have added simple font size scaling to framebuf
https://github.com/pycom/pycom-micropython-sigfox/pull/131
result on small oled

[robert-hh]

@livius That's nice. You may however also have a look at the work of Peter https://github.com/peterhinch/micropython-font-to-py
It deals a lot with fonts, and it is well suited to large & nice fonts and use it with the framebuffer module.

[livius]

@robert-hh
Yes, i have seen it before. Great work :)
But it require to store somewhere font in particular size.
This is simple alternative.
