Any SPIN programs interfacing to wi-fi modules WX ESP8266 or ESP32?

macrobeak · April 6

Hi,
Is anyone aware of any sample SPIN programs for the above wi-fi modules?
I have done a search of obex and the web I cannot find any.
Many thanks . .

There was some work done with the ESP8266 a few years ago. It was in a thread with ESP8266 in the title.
Was it Rayman?

of course it depends what you want to do

I used ESP8266 loaded with NodeMCU running the Lua interpreter interactively.
So you just send Lua commands via serial.

You don't need any special object for this except SERIAL

I think the op wants examples of spin that shows using the CMD structure provided by the firmware included with it.

I use the wx device's serial port with fullduplexserialplus on the prop to send ANSI ESCAPE control codes using the telnet port 23 with putty.
Its a nice way to format the debug output.

Example code is just dumping ansi codes to the serial input on the wx device.. Its pretty simple.
Connect to port 23 of the ip for your wx device using putty.

https://www.parallax.com/product/32420s

The propeller RES pin goes to the WX RES pin. (gpio12, DTR)
The propeller TX pin goes to the WX DI pin.
The propeller RX pin goes to the WX DO pin.

Connect the wx device to your network and open its ip address.
The propeller wx page should show.
From there you can upload a new copy of the latest firmware if there are any (https://github.com/parallaxinc/Parallax-ESP/releases)

If you compile the above prop code i attached, using the PropellerTool software https://www.parallax.com/sites/default/files/downloads/P8X32A-Setup-Propeller-Tool-v1.3.2.zip
Generate a binary by pressing F8, and save the binary to c:\temp\propcode.binary

You can download and extract the proploader to c:\temp\proploader.exe https://github.com/parallaxinc/PropLoader/releases/download/v1.0-37/proploader-win.zip

Then run this by pressing the start button, search for program, type in cmd.exe
press enter and open the program when it finds it
that opens a command prompt, then paste this command.

c:\temp\proploader.exe  -I yourwxnameoripaddresshere -e -r propcode.binary

you WILL need to change yourwxnameoripaddresshere to your actual wx ip address or name.

It will upload the code to your prop connected to the wx device on wifi.

Then you need putty https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html
And open a connection in putty, telnet port 23 on address: yourwxnameoripaddresshere

So now you can wirelessly program, and view the debug output of any propeller based project with the parallax wx device, and these instructions.

Minor issue with one line, causes spin compile failure:

Clock Loop wrote: »

        term.str(string(":Hours   ")

Simple fix:

        term.str(string(":Hours   "))             '' fixed missing ")"

Excellent catch, no idea how it slipped in. Original fixed.
I suppose i could have made the timer code actually work by including the proper code..

But, this was just a demo on how to format ansi command codes to a ansi compatible terminal program over telnet.... didn't want to add more complications that might confuse.. thanks again!!

More ANSI Escape sequences
(ANSI Escape codes)

http://ascii-table.com/ansi-escape-sequences.php

Esc[Line;ColumnH
Esc[Line;Columnf 	Cursor Position:
Moves the cursor to the specified position (coordinates).
If you do not specify a position, the cursor moves to the home position at the upper-left corner of the screen (line 0, column 0). This escape sequence works the same way as the following Cursor Position escape sequence.

Esc[ValueA 	Cursor Up:
Moves the cursor up by the specified number of lines without changing columns. If the cursor is already on the top line, ANSI.SYS ignores this sequence.

Esc[ValueB 	Cursor Down:
Moves the cursor down by the specified number of lines without changing columns. If the cursor is already on the bottom line, ANSI.SYS ignores this sequence.

Esc[ValueC 	Cursor Forward:
Moves the cursor forward by the specified number of columns without changing lines. If the cursor is already in the rightmost column, ANSI.SYS ignores this sequence.

Esc[ValueD 	Cursor Backward:
Moves the cursor back by the specified number of columns without changing lines. If the cursor is already in the leftmost column, ANSI.SYS ignores this sequence.

Esc[s 	Save Cursor Position:
Saves the current cursor position. You can move the cursor to the saved cursor position by using the Restore Cursor Position sequence.

Esc[u 	Restore Cursor Position:
Returns the cursor to the position stored by the Save Cursor Position sequence.

Esc[2J 	Erase Display:
Clears the screen and moves the cursor to the home position (line 0, column 0).

Esc[K 	Erase Line:
Clears all characters from the cursor position to the end of the line (including the character at the cursor position).

Esc[Value;...;Valuem 	Set Graphics Mode:
Calls the graphics functions specified by the following values. These specified functions remain active until the next occurrence of this escape sequence. Graphics mode changes the colors and attributes of text (such as bold and underline) displayed on the screen.
 
Text attributes
0	All attributes off
1	Bold on
4	Underscore (on monochrome display adapter only)
5	Blink on
7	Reverse video on
8	Concealed on
 
Foreground colors
30	Black
31	Red
32	Green
33	Yellow
34	Blue
35	Magenta
36	Cyan
37	White
 
Background colors
40	Black
41	Red
42	Green
43	Yellow
44	Blue
45	Magenta
46	Cyan
47	White
 
Parameters 30 through 47 meet the ISO 6429 standard.
 
Esc[=Valueh 	Set Mode:
Changes the screen width or type to the mode specified by one of the following values:
 
Screen resolution
0	40 x 25 monochrome (text)
1	40 x 25 color (text)
2	80 x 25 monochrome (text)
3	80 x 25 color (text)
4	320 x 200 4-color (graphics)
5	320 x 200 monochrome (graphics)
6	640 x 200 monochrome (graphics)
7	Enables line wrapping
13	320 x 200 color (graphics)
14	640 x 200 color (16-color graphics)
15	640 x 350 monochrome (2-color graphics)
16	640 x 350 color (16-color graphics)
17	640 x 480 monochrome (2-color graphics)
18	640 x 480 color (16-color graphics)
19	320 x 200 color (256-color graphics)

I have not tested all these sequences with putty, use at your own risk. (of confusion)

Clock Loop · April 7

And we can even generate graphics with putty and these sequences,... ANSI art.

You can also, using putty, and either the WX device or a simple serial port, view ANS files directly with the propeller, and putty.

You can generate your own ANSI art using ....

Playscii
http://vectorpoem.com/playscii/

I generated an ANSI image of the parallax logo using it.
But it doesn't work, so if anyone wants to figure out why the ansi files made by playscii will not work..

The ANSI for the storm trooper was found here:

http://blocktronics.org/artpacks/
The Blocktronics Detention Block AA-23

You can see rendering of the pack here
http://pc.textmod.es/pack/blocktronics_detention_block_aa-23/

I didn't mean to make this about ANSI stuff.

Just showing that ANSI terminals are pretty useful with microcontrollers.

Learn has some getting started tutorials with C(maybe spin as well, I can't remember).
