Really impressive - as soona s ai complete the current PCB I'm working on I plan to contact Dream and see whats possible - I'd like to use there later SAM5xxx series IC's as we can then easily make a CPC "Sound card" that outperforms the Roland box :)

GUNHED

Oh, I need to ask, because we just developed an expanded serial mode, so I got distracted.

Any more details on the extended serial mode?

Hello dear LFS users...

For the LambdaSpeak FS there is now Firmware 10 and an updated RSX ROM for it.
The update is about the serial connection / protocol, which is now more save. (see my homepage).

If you need you ATMega644 updated with new Firmware, I can do that for you of course :-)

A new batch of 10 boards is nearly ready btw.

Is there any interest in XMODEM transfers using the serial port?

You mean the CP/M tool XMODEN? It's nice to transfer files via Putty to the CPC. Why not?

For today I added to the ROM for LFS just two new commands, to transfer data using XMODEM protocol:

|S.XBLK: The command '|S.XBLK,address,length' will send a memory area to the serial port using XMODEM. The parameter 'address' defines the start address in RAM and 'lenght' defines the number of 128 byte blocks.

|R.XBLK: This command '|R.XBLK,address' is used to receive data via XMODEM and to store it in RAM at 'address'.

Attention: Before using commands '|S.XBLK' and '|R.XBLK' please switch the LSF into serial mode! Stable up to 14400 baud, tomorrow I'll make it even faster.  :)

Today, eventually I got the Click2Speech Boards, so the next 10 units of LFS are nearly ready to be shipped. First I want to get the 3.5" male 2 male though, to add them to the LFS. Then I will thoroughly test every unit. The price will be around 55-60 Euros plus shipping. I don't know exactly yet.


If you want an unit let me know, and I will put you to the preorder list (see first post).

Great news, I suggest anyone considering a unit to grab one while they are available - as the world-wide semiconductor situation is really really critical, almost any new IC orders are "52 weeks+" which means we have no idea when we can provide stock.

I'm constantly get requests for help with sourcing or help / suggestions with redesign... but its like chasing your tail, redesign a new part in and it or something else becomes 52 weeks plus lead times...


GUNHED

That's exactly how it is. 'Waiting times' for chips are crazy!


BTW: Does somebody know where to find very short cables with two male plugs (3,5mm jacks)?

How short and how cheap should it be?

Ymodem would be safer (better error control, not adding characters at end of file so it is a multiple of 128 like on the Notepad) and better as it can send the name of the file, beware of the different of ymodem implementation (like xmodem though : checksum, crc, 1K...)

Thanks for the link. But 6 Euros is much money (for the buyers).
Eventually I got one for 2 Euros per piece with golden contacts.

On a short distance 5 Volt serial protocol XMODEM is great, because it works with 128 byte blocks and the protocol is clearly defined. Adding characters is no problem on the CPC, because it operates with 128 byte records (on disc) and these blocks get filled up using &1A anyway.
In addition it's 'spoken' by nearly everything.  :)

However, to add YMODEM is no deal and no problem.  :)  Which one (exactly) do you want? I will add it for file transfer if you like.



Just estimated the final price of the LFS per unit: 55,44 Euros

Well, this was a double post, but since I can't delete it I try to say something meaningful...  :picard:  Waiting...  :picard2:


Let's say... One fully tested and working LFS including shipping will be 57 Euro.

Two more units can be ordered right now. Then they're sold out again.

Good news: Got a dozen of 4 GB SD-cards for cheap. They will be my present of all new LFS customers, including prefilled MP3s (just to demonstrate the MP3 jukebox).  :)

Ymodem CRC 1k as seen in http://pauillac.inria.fr/~doligez/zmodem/ymodem.txt
Ymodem-g seems a bit too much for the CPC ?
Zmodem would be a dream of course

Why not |SUCK and |BLOW?  My Amstrad used to like sucking people's d*** (data).

Any chance for a companion board that could be external to the Mx4 bus - as likely only needs power... with like 4 or 6 stereo 3.5mm inputs, and 1 stereo 3.5mm output - all mixed so we can use CPC audio, Speech Synth + mp3 board, PlayCity and future audio items at once without constant plugging / unplugging... if on the Mx4 bus, would bluetooth audio out be possible to sync with headphones?

Because SUCK is another protocol compared to XMODEM (see Vortex SIO documentation). No, this is not a joke - SUCK and BLOW do have a defined protocol.

That's a great idea. I always wanted a little sound mixer for 5x 3.5" in and one single out - going to the stereo you what you want. Would be awesome to have such a thing!!!

How is a companion software not off topic, but a companion hardware off topic?   as great as the Llambdaspeak is, i need multiple sets of speakers to hear everything... i have 6 speakers on my desk for 1 CPC and still cannot hear everything.
