Re: A simple shell for pyboard

Thanks Robert and Dave!

I'm a beginner, so it may or may not be "easy" for me to write a cp method, but yea, you've both given me a bunch of examples to work from (and encouragement!) so I might give it a try...

Yes, using cat with redirection will work...

Thanks much!
Keith

Re: A simple shell for pyboard

Hi Dave- Thanks for making this shell for micropython available! Fun, convenient, and useful! This is an old thread, so I wonder if your shell.py and/or cmd.py has been updated since? I'm wondering if there is a cp command, or maybe there's a different method you use the shell with to copy files? Th...

Re: LCD 1602 - Library

Thanks Dave and mcauser! So I finally discovered the problem. I removed everything else from the setup (to prevent complications) and changed the frequency as you suggested and it still didn't work... but I was able to finally get a scan working... and the default address of this board is 0x3f! (No ...

Re: LCD 1602 - Library

Thank you! That's a big help, but still no joy with or without pull up resistors. Do I need to select an address, or am I correct that the default address of 0x27 needs no jumpers? To make sure I am doing this correctly, here's what I've done: I copied the contents of pyb_i2c_lcd_test.py to the pybo...

Re: LCD 1602 - Library

I'm trying something similar using a pyboard and the 1602 LCD and the PCF8574 I2C backpack, but can't get it properly wired. I'm using 2K pull up resistors, I haven't tried loading any software yet just trying to scan to make sure it is wired correctly. The LCD shows only a single row of blocks. Her...

Re: using tsl2561 light sensor with a pyboard

Thanks Peter. As a beginner I don't know what I don't know... so having a confirmation that it is not likely to be a memory related issue helps me to more easily concentrate on the code.

Re: using tsl2561 light sensor with a pyboard

I'm also attempting to use the adafruit tsl2561.py to play with a tsl2561 board connected to a pyboard and am glad to find this discussion (albeit old now). I'm using Linux (screen) to connect. I keep getting a OSError: [Errno 19] ENODEV error. Reading some other posts this would normally suggest a ...

Re: A few beginner questions- pin id, pull_ups, USB connector

Thank you Peter, that's very helpful.

I also going to be studying the REAME.md file on your Micropython-scheduler github page - very instructive!

A few beginner questions- pin id, pull_ups, USB connector

As a beginner I'm finding the documentation a bit overwhelming. I've never worked with digital chips before. Where do I find (how do I determine) which pins can be used for GPIO? .... any of the X or Y pins without exception? Where do I look to identify which pins can be configured to use an interna...
