Thanks, Peter. I'll have a go at it later, or possibly tomorrow. I've now had emails for your last two replies, so it seems the Reply button isn't required. I needed to tick a box that wasn't obvious, when posting a reply. It seems I failed to see it the first two times, and using it when editing my second reply didn't work. It's a little different to other forums I've used.

Hi Andy, maybe I haven't been using the reply button. Read my latest post.

Hi Andy, I guess prerequisites are a fact of life and we have to start somewhere. But that's also where we ask questions and look for feedback too. I think I've also mentioned so many times the different terminal emulators that one can use, but I use minicom because it works properly and is a fully functional ANSI terminal emulator that can also keep up with high baud rates too. But when it comes to Windows I used to use and still use TeraTerm. But Mecrisp on the RP2040 only uses the hardware UART,...

Sorry for the triple post. I'm still trying to get SourceForge to let me subscribe to this thread. It seems posting again, not editing, might be the only way.

I'm struggling to even understand how to install Tachyon Forth, at the moment. For example, this part: "In a separate linux terminal startup minicom in ANSI mode 921600bd and ^AU to get it to add a CR (Mecrisp outputs a single LF instead of CRLF)" Is that using a USB serial connection, or an FTDI, or similar? Also, does it have to be Minicom, on Linux, or could I do this with TeraTerm, on Windows, which I'd be more comfortable with? The installation seems to assume knowledge that an existing Tachyon...

Hi Peter, Thanks. I don't seem to be getting notifications, from Sourceforge, so I only just saw your answer. I've turned on the settings I can see, but that doesn't appear to work. I really don't know where to start with Tachyon. The documentation just seems to talk about the parallax chips. I don't know what applies to to the RP2040, yet, and I'm really not sure what I should be reading about it. I had assumed there were discussions that I could read to get up to speed, but I can't find any. I...

Hi Andy, The Tachyon extensions to Mecrisp on the RP2040 were done as a bridge at the time I was looking at writing a Tachyon kernel for it from scratch. I played with the RP2040 for a while and I should come back to it I guess. I will dig out the board and check the files as well. Do you have some suggestions ?
-
I'd like to make a suggestion about the wording of the SourceForge project summary page, for Tachyon Forth. I would start a new thread, but I don't currently see a way to do that, possibly because I only recently subscribed here. I saw mentions of Tachyon Forth extensions in the Mecrisp Forth discussions, but it hasn't been all that easy to track down anything relevant about that. It appears that there is support for the RP2040, now, but that's not mentioned on the first page people are likely to...

Exciting news Peter, interactive line editing and history sounds like a great enhancement. Many thanks for making this available, Tachyon is a great Forth implementation.
-
Just to let you know then that TAQOZ is going through a revamp to V3 which also reduces the compiled kernel to the minimum to support loading EXTEND which will have make it a lot easier to make improvements. I have already redone all the number processing and dump routines, and now I am implementing the ABORT/QUIT console routines which will allow for interactive line edit and history as well.

Just wanted to say hello and thank you again Peter and to hail new dvelopments. I check in here mostly every day and today .. .what a nice surprise - FRED has officially been introduced to TAQOZ. I will give it a spin this weekend, happilly neglecting ever more important "weekend duties".

After some fiddling with the relevant bits and further thinking I finaly understood why it didn't work at my first attempt. The reason was trivial - I have connected the RTC board to already booted Pico so the initial config of the RV-3028 didn't happen as it gets probed and initialised on boot. After manual initialisation it worked as it should. Stupid me. Apparently, I was too excited to play with my ugly RTC board.
-
Hi Peter, Just one more question: does your RV-3028 support code for Tachyon extension to Mecrisp provide for the tricke charge option set to ON ? I can't seem to find the relevant part in the code and it's not working with my ugly RTC board when I installed a big enough backup capacitor in place of the pull down 10k Ohm resistor (the one that sticks out to the left of the board). The fresh from the factory setting has this set to OFF, probably to prevent users from destroying the non rechargeable...

Fixed! Thank you. And my ugly, but working, RV-3028 makeshift board. No backup capacitor or battery for now. Had some real soldering fun with it.
-
Fixed! Thank you.

Just had a quick look and seems that I chose to write it to the RTC on DATE! which means DAY! only writes to the buffer and depends upon a following DATE! Other than that you can make it to a 3 RTC! directly if that suits. I will have to check it out later.
-
Hi Peter, I stumbled across this small nuisance yesterday when attached my makeshift RV-3028 RTC board to the Pico running your Tachyon extension. The time and date sets up just fine but the DAY! stubbornly refuses to set the proper week day. No matter what I try to set it to (1-7) .FDT returns Monday. I'll look to this more closely today but maybe the solution already is implemented but just not in my system (newer version of Tachyon extension maybe) ?. The other oddity I will post later today when...

Hi Peter, Things are good at my end and so I hope are at yours too. As for the BT module I went for the BGM220P and got BGM220-EK4314A board that has just arrived and was cheaper then the module itself. Nice little board so I got more than one, of course. Now I need to make freinds with the Simplicity Studio just to try it out as it most probably needs some initial configuration to work and get discovered as a BT device on the air and at the PC side as well whic it doesn't apparently out of the box....
-
Hi Maciek, hope things are going well for you. I must confess that I have a drawer full of the bare HC05 modules I bought one time to mount on my own little adapter to plug straight into my 4x2 Prop Header which of course includes power. However I have been considering the C3 since it is so low cost and has BT5/BLE and WiFi as well. I must get some and see how suitable they are for BT serial. My module has a cheap n tiny micro on board to intercept a reset sequence so I could still reset the Prop...

I've been scratching my head as to which BT module is worth looking at when considering a wireless connection to the P1 and P2 boards. I do not need or want WiFi and I need it to be relatively low power. I am considering the ESP32C3 or ESP32WROOM/WROVER with the WiFi disabled ( I think I've read it's possible) or a BGM220P from SiLabs. The nice thing about the later is that it also comes as a nice dev board in a form of BGM220-EK4314A that supports built in packet monitoring interface and full debugging/programming...

No, no, do not feel bad about not answering in an instant. I didn't expect the answer to be quick anyway. I asked this because of something that caught my attention while browsing your p-cloud repositoreis. I must've seen some new addition there or something and thought you might have upped it a bit. I can't even remember what it was exactly. Yours and Mecrisp sites are my almost daily readings. Sometimes I check the forth2020 site in hopes for a new YT video that could be of some use to me but haven't...
-
Ah, sorry, I am late answering this question. I started V6 but hadn't gotten very far although there are things I want to change in Tachyon that rather annoy me now. I'd add a standard line edit buffer for interactive use and perhaps a very small history buffer, at least the previous line. I may revisit this sooner than later as I will be using edit buffers for interactive use with TAQOZ and some other Forths too. The other thing is that I will have a proper QUIT routine that can be user revectored...
-
Hi Peter, is the V6 ZOOM mature (stable) enough to make it official (in a sense like the tatest stable version) ? I can't help myself but instead of sticking to a given project I tend to get more and more distracted with other interesting things. The older I am the worst it gets. Anyway, I am still circling around forth related stuff hence the question.

Hi Maciek, I thought I fixed this up before but here's a new link that I've checked in a private page. https://u.pcloud.link/publink/show?code=kZksaNXZvXfNKW2FOdXtGhoBuq4QhRblvjCk# or https://tinyurl.com/Tachyon-pCloud

Hi Peter, Yes, I've found the new link somewhere in your posts on the mecrisp forum, I'think, have it bookmarked and check in there daily :). I've noticed some new stuff there recently. Thank you.

Your pCloud link appears to be broken. I get "This link is deleted by the owner" message. It's fine if it's intentional. Otherwise it's maybe something to bring to your attention.

If text files are no larger than say 64kB then we can allocate a buffer of that size and allow for inserting and deleting sections of text easily. RP2040.FTH is already 54k but it should really be broken up into EXTEND and SDFAT perhaps. Saving a 64kB file even slowly only takes about 64ms but in block mode will be a lot faster. I think I would have a temp file open to facilitate undo's etc. If though we are allocating a text edit buffer then we don't have to limit ourselves to fixed sized blocks...
-
For sure we could add syntax highlighting, or a theme at least. While SED edits in blocks, it is not your traditional block editor that relied on block numbers but rather it is simply working on a 2k block at a time in the opened file. So essentially it can be a unterminated lines but I prefer the fixed width CR terminated lines so that these can still be handled and read as standard text files. I am thinking of a way of copying and inserting text though that will still be compatible with this system....
-
Yes, Peter. For me SED is an excellent start and far beyond that, in fact but I can see nothing wrong with other people wanting more :). The colored syntax would be nice, wouldn't it ? Just for the looks as I do not see much value in the syntax automatic control in TAQOZ/Tachyon. Be it for some flavor of Cor Python or...you know...then I'd say it should be a mandatory feature but not so with forth. I just thought it's interesting so I linked it here. The 5Fs rules. I may as well be very pleased with...

Hi Maciek, I started SED to do just that to work on a terminal or VGA and I use that way myself with my PS/2 keyboard interface (over a USB connector). There's a mode in SED that line terminates each line of a 2k block. Sure, more can be done with it but it works well and I have edited files in it. It uses the standard keyboard navigation keys such as arrows and pgup etc. Why wouldn't that be a good start, a very good start in fact? https://forums.parallax.com/discussion/172819/sed-the-simple-se...
