Re: LCD 1602 - Library

Hi Dave- 1st of all, thanks for your great work here- got it working on my 8266 & 1602 (with level shifter) without any problems at all. Can you explain the syntax of putstr(), please? I'm tripping up on the syntax you use in your Test script: lcd.putstr("%7d" % (ticks_ms() // 1000)). Please explain...

Re: PyB-to-PyB using I2C?

Hi guys
Just wondering whether there's been any further development of the board to board I2C?

Personally, I'm using ESP8266.

My goal is to use 2 devices to monitor each other to improve up time.

Thanks

Hi Damien- thanks for this resource- using it to "spread the word"!

Any chance it can be upgraded to 1.10, please?

Many thanks

Re: MicroPython Documentation Discussion

Hi mattyt

Can a note be added to the ESP8266 Documentation on the "maximum Period" a timer can be set to, please?

I can confirm that the MAXIMUM value is 6870947 (1:54:30.947).

Please see viewtopic.php?f=16&t=5116&start=10 where this has been discussed.

Thanks
Peter

Re: Maximum possible machine.Timer period

Hi all The MAXIMUM value is 6870947 (1:54:30.947). I tested and verified on uPython 1.9.4 ESP8266. >=6870948 does NOT work. (My source came from Lua: https://nodemcu.readthedocs.io/en/master/en/modules/tmr/#timer-module. Lua Timer (tmr.interval) initialises in a similar way to uPython.) I wanted a 1...

Re: Maximum possible machine.Timer period

Hi. Was a maximum Period value found (It needs to be added to the documentation!)? I'm experiencing the same with the difference of using a hw timer. I started off with the equiv of 12 hours (callback function not called), and then 21610000 (~6 hours) with the same result. It works when I use a shor...
