MicroPython Forum (Archive)

First: The this is *not* the official documentation on how to build esp-open-sdk and MicroPython, rather this is information that I found helpful for building on Debian and Raspberry Pi. See http://forum.micropython.org/viewtopic.php?f=16&t=1689 and http://forum.micropython.org/viewtopic.php?f=16&t=...

did you check with a logic analyser? I've been looking for a reason to try out my Rigol 1054Z decoding! The good news, is that the oscilloscope is really quite cool. The bad news is that the resultant data seems to have a problem (see attached picture). Note all the question marks between data elem...

thanks for your reply. well, that sounded fairly promising, but does not seem to work on the V02 alpha that I have (shipped March 16 - is that the most recent?) >>> from machine import Pin, I2C >>> i2c = I2C(scl=Pin(5), sda=Pin(4), freq=100000) >>> print(i2c.mem_read(0x68,0,7)) Traceback (most recen...

edit: update subject with specific (e.g. RTC1307) I was wondering if anyone has some working sample code for multi-byte reads from the I2C bus? I'm using the mp-esp8266-firmware-v02.bin #4 ets_task(40100278, 3, 3fff4658, 4) MicroPython v1.6-336-g6f5af76-dirty on 2016-03-16; ESP module with ESP8266 T...

fwiw - here's an example of the garbled text pasted into Putty in MicroPython "Ctrl-E" mode from Windows. There are 114 lines all exactly the same created in Notepad. Part way in, the text gets garbled. ...initial lines omitted... === print("hello world") === print("hello world") === print("hello wo...

I use the china boards a lot my self (LoLin and Geekcreit). As far as I can tell, they work very well with Micropython (and they should come with the same ESP as the Huzzah). That's good to know! I'm curious if you've used your LoLin board in a Linux environment? My Amica board gets recognized with...

Hi Stefan & thanks for your response :) Note that the print "Hello World" seems to do nothing: no error, no message Have you tried to make "pyboard" follow the output - e.g. like so: python pyboard.py --device COM10 --follow -c "print('hello world')" the "--follow" is interesting; it prints hello wo...

thanks for that! yes, the "pyboard.py" works perfectly to upload! (well, from my Raspberry Pi). This forum has a good thread with tips & suggestions for the Linux option; I posted my comments here: http://forum.micropython.org/viewtopic.php?f=16&t=1546&start=10#p9623 I also have python 3.5 on my Win...

Once the firmware is uploaded following command will connect to micropython on the ESP board and give you the REPL prompt : sudo screen /dev/ttyUSB0 115200 To exit: CTRL-A CTRL-D this was really helpful, thanks! (I was leaving off the 115200 param, and wondering why it would not connect, D'oh). als...

I've been having problems with the "Ctrl-E" (right click to paste) and "Ctrl-D" to send a block of text to the ESP8266 via Putty. I would occasionally get error messages for code that otherwise looks ok. Sometimes it would appear some text got "lost" in transit. And now while pasting, I ended up wit...
