Re: My LoPy board arrived

Well, after updating LoPy to fw 0.9.1.b1 today it is crashing in 10 seconds after reset/boot without running any user program, just the stock boot.py It means can't connect to it via WiFi anymore.

Previous release was able to blink LED for 3 days.

:? :cry:

Do you mean any architecture, like PIC24, PIC32 or AVR?

Re: Free RAM on MicroPython boards

Updated LoPy to 0.9.1.b1 firmware released today. Now free RAM is only 71152 bytes Also, every execution of gc.mem_free() is decresing it by 64 bytes :(

Re: Question on arithmetic calculations

Now I remember, several month ago there was an issue opened at GitHub about a similar issue if I'm right. It looks the same here.

Code: Select all

import os
os.uname()
returns a tuple with release, version and other parameters. On my board release='0.9.0b' whatever it means.

Question on arithmetic calculations

Just started to play with LoPy and have a problem explained below. It is not LoPy specific but related to MicroPython I guess, it is why asking here. machine.freq()[0] / 1000 / 1000 returns 80.00003 which is OK But machine.freq()[0] / 1000000 returns 8.181962e-07 which doesn't look the right result ...
