hi


is it possible to add a key at boot time to cancel autoexec.bas to run ?


because i have make a autoexec to launch rpm for exemple that i can't quit with the esc key (like in stock cpc, i think the m4 catch the esc ...)


i must  erase autoexec on a pc


thanks in adavance

It's possible, but it was a lot of hacking about (and a long time ago) to get the autorun feature to work, one of the side effects was ESC to break not working. Maybe I will re-visit it some day.
However I guess you could do some Basic key checking in your autoexec.bas to skip ie. launching rpm. Say hold space to exit to basic.

i must  erase autoexec on a pc

You can also eject the microSD, turn on the CPC and insert the microSD, then erase (or rename) it from the CPC.

Hi all,
i am trying to build xfer on a ubuntu 18.04 machine (GCC 5.5.0_4) so i can transfer files to the M4 but it does not compile from source and i get the following error: 

gcc -O2  -W -I. -c parse.c -o parse.o
parse.c:10:25: error: conflicting types for 'strncasecmp'
        #define strnicmp strncasecmp
                         ^

Any help appreciated!

Simple fix: in parse.c change

Code: [Select]

#ifdef __unix__ to

Code: [Select]

#ifndef __unix__ or just delete that entire block.

Great!!
Worked like a charm!!
Many thanks

I am using an M4 with 2.05B12 and trying to load YANCC with |romup and it seems to result in corrupt text in the rom slot with |m4help and a non-functioning rom.
I ran the config.bas to create the configured rom (basically all N options) and then |fcp those over to the m4 so i can |romup them which seem to succeed but an M4 reset shows the corrupt text in the rom slot with |m4help and neither commands works.

I tried slots 1, 2, 11 and 12 out of interest but YANCC-CO.rom and Launch.rom both do not seem to install correctly.
Any one else tried to install YANCC140418b with 2.05B12???

Sorry, today seen your mail, do you have still problems? (yes: write me a PM)

Hi SOS,
i tried again today with the same versions and all worked fine!!
Sorry must have been user error i.e. me!!! 

cheers

Hi Duke (or anyone else programming the M4).  What is the fastest you can make the CPC hit a URL (HTTP GET)?  Firstly where we care about a response (such as a payload of 128 characters), and secondly when we don't care about a payload response back to the CPC beyond 200.  How many times a second?

Hi @Duke : Recently WiFi becomes more and more a pain, too much routers are everywhere and sometimes I need to reset my router a couple of times per hour(!) to have a signal again. Now this for PC world.

Also for CPC world, the overwhelming number of waves in the air don't make it more easy.

So here my question: Would it be possible to make a M4 board with cable-plug? Because a cable would be much more stable.

Can you do that?

What do all others thing about that idea?

[VincentGR]

That and add at least 512KB

We will end up with a new Symbiface with RJ45

Some years ago I tried interfacing some Wiznet modules with the CPC. I/O mode was a pain and fail with the address autoincrease mode, the counter some times increased two in a read, but writing was good... "Ram" mode was not an option because you have to page 32kb, but now with the 4mb ram expansion which is some kind of "expansion of expansions"with the first 512kb compatible with legacy expansions, then a 8mb could be done with 4mb and a second 4mb reserved for "memory mapped I/O" for this kind of devices... Other way is using a microcontroller and SPI mode...

I guess you could try to change the channel you use for WiFi, I think there is some smart scanners for android/windows that can detect which is best (least used in your area).

I could add RJ45 if I wanted (I already made a board with that, not for the CPC -> http://www.spinpoint.org/2016/01/14/plc-datalogger/ ), but it takes time and effort and I really don't have much time/energy for these things at the moment (maybe when the winter comes!).

[GUNHED]

Thanks for the answer Duke!    Well, me personal I can't change the channel. But if you could exchange the Wifi by a RJ45 (guess that's ethernet?) then it would be awesome. I would take at least two of them and I guess others too (see responses). I know you're busy, but maybe one day you can do such a board.

Duke,

Can I still purchase an M4 from you - or its it a DiYkit? either option is good for me. I can assemble a PCB from a partial kit of parts (SMD no problem) if your short on time to build the board (I'll have all "common" components it stock)...

I'd be interested in one for my Amstrad CPC6128...

Thanks

Yes I still make them. Current lead time is about 6 weeks (after I receive order confirmation), due to an overwhelming amount of orders and slow supplies on certain parts.  I don't sell any DIY kit.

this must be the longest running thread for hardware on this forum, congrats for surpassing 100 pages!

And its by far the best selling expansion for CPCs / Plus computers. I'm curious how much devices (f.e. ROM boxes etc.) they did sell in the 80ies and 90ies?

Use only channels 1, 6, 11 which have less nuisances from nearest channels (see in french : https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwjY3rvaxZPqAhVHXhoKHUAjCAgQFjALegQIBhAB&url=https%3A%2F%2Flafibre.info%2Fwifi%2Fquel-canal-wi-fi-choisir-pour-optimiser-son-debit%2F&usg=AOvVaw2NKCkw5h7Shc6C9RY9jKVD

It's still better to use a channel that other people are using because inside one channel, all wifi devices are able to live as good neighbours. Whereas wifi devices of other channels are bad neighbours (noisy).

Sorry for the delay in responding - PM sent,

Thank you.

Well, how to do that? The Wifi-Box is just a box. No DIP switches. Can I select that with software? Which one?

How to do that with the M4?

Normally channels are set in the wifi router. you create the wifi network with a name, SSID, and choose what channel, even frequency, 2.4 or 5.0 ghz. When wifi clients like M4 connect to that network.

Thanks for the advice, but it can be done nowhere. So it would be great to have a M4 with internet-cable-socket.

That is quite unusual, what model of router do you have?
