Title: LambdaSpeak FS
Post by: GUNHED on 18:50, 18 February 21
Information leaked, so here it comes....

The LambdaSpeak III is a great expansion with lots of features.
However it is not really cheap. Parts just have their price.

But... we decided to release the LambdaSpeak FS, which is nearly the same as the LS III.


What are the differences?

- The SPO256 chip is missing (no problem, the Click-2-Speach does the job anyway)
- You get an additional serial port, suitable for MIDI IN and OUT and way more
- EEPROM missing
- It's way cheaper!


What are the features?

LambdaSpeak FS (2021)
- Perfect Speech Synthesis (English and Spanish!)
- MP3 Player with SD card
- Real Time Clock (native OS, CP/M)
- PCM Sample Player
- 70 new RSX Commands
- Software for CP/M too
- Emulation of:
  * SSA-1 speech synthesizer
  * dk'tronics speech synthesizer
  * Amdrum Drumkit
  * Epson and DECtalk Modes
- Thermo sensor
- Serial Port (up to 625000 Baud)
- MIDI IN and OUT Option
- Two DSKs of software
- MX4 connector
- Help & Support granted

How to get it? Well, we wait for the next promotion for the Click2Speach board to save $20. Meanwhile we're building the boards.

Should you buy one?
- If you have the LS III, then NO  ;) :) ;)
- If you have no LS, the YES  :) :) :)


Preorder list for first batch of 10 units:
- Rambler
- valfac
- RetroCPC

You are the lucky one. We work on some new software for LFS, it will run on LS3 too.  :)

Good question... the main "thing" here it this one...

https://www.mikroe.com/text-to-speech-click


At the moment the 'Text to Speech' Module costs 39 Dollars, but from time to time they have a promotion and the price drops to 19 Dollars - we wait for that now.
The remaining components are maybe around 30-40 Dollars, we need to see where to make the best deals.  :)


Also, the price depends if you want to have the MP3 player (or not) and the RTC (or not).


We use these boards:
MP3: Aideepen YX5300 UART Control Serial MP3 Music Player Module for Arduino/AVR/ARM/PIC
https://www.amazon.de/aideepen-yx5300-UART-Steuerung-MP3-Music-Arduino/dp/B01JCI23JG


RTC: HiLetgo 5pcs DS3231 AT24C32 Clock Module Real Time Clock Module IIC RTC Module for Arduino Without Battery
https://www.amazon.de/Demarkt-AT24C32-Precision-Modul-Speichermodul-Arduino-1PCS/dp/B07NW86D97/ref=sr_1_3?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&dchild=1&keywords=DS3231+AT24C32+Clock+Module+Real+Time+Clock+Module+IIC+RTC+Module+for+Arduino+Without+Battery&qid=1613744738&s=ce-de&sr=1-3


Meanwhile software is getting more and boards will get their first components soon. I'll keep you updated. And if there is a text2speech board promotion please let me know.


By the way, the project page is here:

Software & Firmware update on my HP and here...

What new?
- !ADEXIT can exit the AMDRUM mode
- !LSHELP (hopefully) litte more lookable
- Firmware 5 (can now exit from AMDRUM mode)

Have fun!

You want to use MIDI with LFS or LS3?
Then you can connect via the MIDI breakout board:

https://www.amazon.com/ubld-it-MIDI-Breakout-Board-EZ/dp/B08JC1SZHG/


LambdaMikel made some software for it, see his channel at youtube f.e.


More software is planned.
Therefore let me know which kind of software you would like to have for CPC and Plus computers.
There is MIDI IN and MIDI OUT.

A new software update for LambdaSpeak is out, now with the Digitrakker from Prodatron (Trakker and Player generator adapted for LambdaSpeak).

MiguelSky made me aware that the RAM RSX from disc don't work. Sorry for this, I worked most of the time on the ROM version. I will care about the RSX for RAM soon.

And now here a video of LambdaSpeak and Prodatrons great Digitrakker:

Thanks to Genesis 8, here is the actual software for the LFS:

The RAM RSX doesn't work at the moment (MiguelSky pointed me at that bug), but I will render it working soon. Will keep you updated...  :) :) :)

Hi there!

Today I opened the preorder list for the first 10 LambdaSpeak FS expansion cards.
This is especially for people who want to really use the LFS, not for pure collectors.

If you want one unit please PM here and I will put your nick in the preorder list (see first post).

All the songs which are 'expected' by the MP3 player can be found at Mega Download.
(However, these songs are on you 'present' SD card anyway, but just in case ...)

See here:

Small update of software (RAM RSX now cleared of a bug). New firmware.

for me for some reason the lambdaspeak software update doesn't work, does it work for anyone else?

Which LS do you use? You have the LS3, right?
What exactly is the problem?
Please describe!  :) :) :)

Ah, well. Yes, that's a bit of a wiki forum problem I guess. Try something like "Save link as..." or copy & paste the link. I have the same problem with Chrome too. But it's out of my hands.
In the worst case goto www.futureos.de (http://www.futureos.de) - there to downloads and scroll down.

For the LS3: Lots of new software for the LFS will work there too (of course), but we will need a bit of time to catch up with LS3 DSKs. At the moment we got serial communication and MIDI on the plate.

Thanks a lot for your interest and support!  :) :) :)  Feedback is always a gem.  :) :) :)

Did somebody use the RAM RSX expansion?
Were there problems?
(Recent version I mean)

Seems the the problem was one of the M4 card. Maxam creates binaries with file-length=0. This is a problem when using file copy of the M4 card. I suggest (MiguelSky) to load/save the file by hand, this way the file length is added to the file-header.

News:
The new update has an expanded manual and the first batch of commands for serial communication. I will test the commands during the coming week on real hardware.

Get your LambdaSpeak FS PCB...
RetroCPC did ask me if this is doable. Well, I can ship a bare PCB to anybody. This is 5 Euros for postage and PCB. Let me know during the next couple of days. Later on I will order parts and then they shall fit to the number of remaining PCBs.  :)

Great, nobody wants PCBs, then I start working on the 10 units...

I think that's because by now everybody knows how to order Gerbers from one of these Seeed-alike PCB maker services and can make them themselves for little money. So there is no need for a "man in the middle" in that sense anymore.

Like these Russian dudes that grabbed the LS3 Gerbers from the Github and are selling it on Chipkin.ru:

https://chipkin.ru/product/pechatnaya-plata-14/ (https://chipkin.ru/product/pechatnaya-plata-14/)

I am sure your assembly services will be valued much more! It takes a lot of time effort and skill to make one of these.

Well, I hope you can help me with this... What I would need is a plan which describes which part is which and where it come. And of course where to buy them. IIRC you do have that all.  :)  Meanwhile I do the 'Drahtbrücken'.  ;) :) :laugh:

I got some trouble in making the card pronounce correctly stressed syllables in Spanish as it uses a predictive way of pronunciation quite accurate but not for all words as you can type the accented vowels in CPC. I sorted this issue by using double vowel or hyphens, depending on the word structure. Just in case someone else bump into the same problem.

Like all automatic text-2-speech algorithms, the Spanish Epson parser that translates into DECtalk phonemes uses rules and heuristics, and these sometimes fail. That also happens in English mode btw.

In any case, the acceptable codes should just be standard ASCII (is that ISO-LATIN1?) :

áéíóúüñ  -> E1 E9 ED F3 FA FC F1
so each ASCII character with 8. bit set (> 127) needs to be sent in HEX using \x??.
Hence, the following should in principle work in |spanish |epson mode, but as I said, the parser can make mistakes: 

\xE1, ..., \xF1

Also it's fun to let tell the LS pseudos like "AST" or "PDT"...  :P

The RSX ROM for LSF was slightly changed. Now it does NOT reset the LS at initialization. Because some games need the SSA1 mode or the dk'tronics mode. Well, these games just initialize all ROMs and this does of course also init the LS ROM - and this in turn would reset the LS.

Now, all speech games will work without unplugging the RSX ROM.

Let me know in case there is a problem.

Download as usual ... see my signature or goto downloads at www.futureos.de (http://www.futureos.de)

The new Firmware version 8 is out for LambdaSpeak FS. Enhancements in the serial communication, MIDI and so on. Please update your  ATmega 644 CPU. The new RSX ROM does support it. Here is the firmware file...

Update: Folks also asked for Speak&SID and LambdaSpeak 3, so here it goes.

Not necessarily...the same should already work with LS3 since 2019  ;) I'll try with the LS3 and post a video soon. It should just work. Check out the MIDISYN.BAS program on the LS3.DSK.
