Re: [M100] TPDD emulator on Arduino

[Fugu ME100]

Yes the ESP-12 works really well.  The ESP-8266 is now integrated with the 
Arduino IDE so moving code around is a breeze.  Although there are still some 
issues with sleep etc.  There are also a bunch of libraries like WiFi Scan, 
FTP, TELNET, NTP and OTA updating which make it quite simple to add in those 
features.  The 8266 is a bit of a power hog but otherwise it worked really well 
as a WiFi link and SD-Card interface.I did put together a OSH board some 
time ago to build an ESP-TPDD based interface, it should be shared on OSH

In my case I just used the TELECOM program to set up the FTP or TELNET.  The 
FTP is only to the local SD-Card which can then be accessed via TP-DOS.  The 
only clunky part was booting from the ESP-TPDD as it does not support the 
control lines – too few pins – to react to the Model Ts serial pin status.

There are also some ESP-12 boards available with RS-232 ports that can be 
plugged directly into the Model T, I do not have the link though.

Subject: Re: [M100] TPDD emulator on Arduino

I've been thinking about an ESP8266-based TPDD emulator that can link up to an 
FTP site or act as a telnet to serial bridge at the flip of a switch.

That would be really cool.

Re: [M100] TPDD emulator on Arduino

[Brian White]

I think in both of these cases I'm using interrupts and hardware
sleep/wait-for-interrupt support, so there's no tight loop. (assuming
correct code and correct wiring on my part, of which I make no such claim
:) ). And yes there is serial port init code. I went through a few
different variations on that "while !Serial" kind of thing, but looks like
now I just have CLIENT.flush() ( Serial1.flush() )
I think it's actually behaving now, in both devices. I believe I had
something bone-headed backwards at the time of the video, watching TX
instead of RX with the interrupt. Also there was something about how
quickly the device can wake from sleep, or from different levels of sleep.
If you don't go below a certain level of sleep, then the device can wake up
fast enough not to lose the same byte of data that woke it up.

Re: [M100] TPDD emulator on Arduino

[Brian White]

Couple pics of the adafruit setup.
https://photos.app.goo.gl/N2v6iB45pePNFQNA8

The 32u4 is a much less powerful device, but just about perfect for doing
the job of TPDD. The Teensy 3.5 & 3.6 are far more powerful, overkill for
TPDD, BUT, perhaps really cool for a more feature-full device. The Teensy
has audio hardware and enough cpu & ram to use it. So I was planning on
seeing if I could get it to play cas or wav files, and record them, to act
as a virtual cassette as well as tpdd. Another plan was to use the Teensy's
built-in rtc with some small basic program on the M100 to set the M100's
clock, or conversely set the rtc from the m100.

A dos-installer would be nice too, and should be no problem. There is a
pretty straight-forward example in dlplus dl.c sendloader(), and dl.do
shows the line of BASIC to kick it off.
But it might be possible to emulate what the real tpdd2 does, detecting the
state of some serial pins on power-up, and send the loader based on that
condition, minimizing what the user has to type manually.

Re: [M100] TPDD emulator on Arduino

[Scott Lawrence]

I've been doing a bunch with 32u4 based arduinos recently (pro
micro/leonardo/ss micro/etc).

With these, there's a bit in the start up to make sure that it doesn't
crash when talking to an uninitialized serial port, something like:

while( !Serial );

Or, you could check it with something like:
if( !Serial ) { return; }

and so on.  In any case, it's been my observation that when it's sitting in
these tight loops checking the hardware, the thing is basically running
all-out full speed.  Even just the ( Serial.available() ) function in these
situations can be super laggy.  Even just putting a delay in there helps a
ton.  eg:
while( !Serial ) { delay( 50 ); }

or somesuch.

It might not be the cause of the power drain, but there's a chance it is.
 maybe?

In my experience, those calls checking the serial port seemed to block the
system entirely and cause bad behaviors... :/

Re: [M100] TPDD emulator on Arduino

[Brian White]

I got Jimmy's code working on Teensy 3.5 & 3.6, and on Adafruit Feather
32u4 Adalogger
And modified my copy somewhat. I was playing with getting the top-right
corner of TS-DOS to display the current working directory, and reducing the
power drain.
Some changes are just gratuitous refactoring to suit myself, so that I
could then make the functional changes.

In this video there is a little mystery where the power drain is a little
high on initial power-on, but behaves properly as soon as you actually talk
to the device at least once. I think I figured that out and the current
version behaves properly right from power-on.

Teensy 3.5/6 and the Adafruit device are quite different and have different
quirks. I never pulled both versions together into a single modular code
base yet. I have some messy code to try to make the same code handle
different devices by configurable options amd macros, but it's not really
worked out and so it's still two separate branches, one for each device.

I haven't done anything further since then.

Re: [M100] TPDD emulator on Arduino

[c646581]

Yep, I was working on a TPDD emulator for Arduino called SD2TPDD. The
github page is here:
https://github.com/TangentDelta/SD2TPDD

I kind of lost interest in it and haven't maintained the project in a long
time. I don't have any pictures of the setup, as it was basically just an
SD card reader and RS232 line driver slapped onto an Arduino Mega.

My next step was to port it to a Teensy or similar device in order to
shrink it down to fit inside of the M100.

[M100] TPDD emulator on Arduino

[VANDEN BOSSCHE JAN]

Someone was working on a TPDD emulator on Arduino. Is there any progress? 
And/Or photos?

As I'm starting a course on Arduino programming, I am now even more interested. 
This could become the cheapest stand-alone TPDD emulator yet.
