Unofficial PicoCalc PicoMite/WebMite firmware release thread (V6.00.02RCxx)

[TheKiwil]

I confirm that with the right compilation option webmite work on PicoCalc.

[adcockm]

Nice! I didn’t actually try to do the build with that setting, since I saw some other things were missing, and I didn’t think it would work on the PicoCalc without modification. I spent a lot of time looking over the code but I guess I should have just tried to build it with that setting.

That said, only changing the compilation option and using “WEBRP2350” instead of “PICORP2350” finally allowed me to see the keybaord error others have reported. Doing a WebMite build this way will cause “I2C Keyboard not found, OPTION KEYBOARD disabled.”

The good news is, that might help track down what’s causing the keyboard problem. As far as the build goes,

“WEBRP2350” has most of the components of “PICORP2350”, but it’s missing:

• GUI.c
• -DGUICONTROLS
• pico_multicore

And it has a larger PICO_HEAP_SIZE and PICO_STACK_SIZE set (it’s 0x2000 for both with just the Pico2, and 0x4000 for both with WebMite).

It has a few extra things, but those all appear to be related to running the webserver in the background.

There are also plenty of changes in the code itself. For instance, I’m not sure why, but overclocking is locked down and on WebMite builds you can’t go above 252000, while in the regular PicoMite build for the Pico2 it allows going up to 396000. (I’ve only personally set it to 380000 to play it safe, but the code allows that little bit higher.)

Since multicore was there for the Pico build and it showed the keyboard error, I’m wondering if it’s a question of processor speed, or something else. I was running WebMite at it’s default limit of 252000, but I still got the error. And I’m assuming people using guu’s build may not have even changed the value from the default (which I think is 150000). So it’s probably not the speed after all. I’m not sure what’s causing that error.

I’ll upload a firmware binary release on the github for the WebMite version if people want to try it, but be aware that you’ll get the keyboard error eventually, at least until that gets sorted out.

Release PicoCalc PicoMite V6.00.02RC9_b · madcock/PicoMiteAllVersions

[CarterNo]

Yes the Pico2 firmware worked fine, sorry for the long delay in replying.

I then noticed a cracked to the lower right corner of the screen and then upon closer inspection the line where the ribbon cable attaches…

I’m basically just an idiot as I damaged the screen changing Pico boards and I now am waiting for a replacement!

So back to the Colour Maximite 2 for me

[adcockm]

Thanks.

I feel your pain. My screen also broke after I swapped modules. I’d done it plenty of times before and everything was fine, but the last time the screen shifted slightly and I failed to notice. I’ve got a replacement on the way too.

[cjstoddard]

After seeing posts about screen breakage here and on Discord, when I was assembling mine, I taped the screen down with a bit of electrical tape.

[Toml_12953]

So you don’t plan on keeping this up with the revisions (currently RC11)? I hope someone else can. The hardware is too good to be stuck with older versions that may lack features. One example if the BIT command and function. It was removed from PicoMite but added back in with revision 11.

[adcockm]

Is this not the official source code repository?

Version.h

It’s currently at RC9 and I am unaware of any source for RC11.

If you’ve got a link to a different official source repo for PicoMite then I can use it instead. At present my repo is up to date with this one.

@Toml_12953 I had to dig to even find any mention of it, but apparently about 6 hours ago a binary only release of RC11 was released. There haven’t been source releases since RC9. You must have seen that PicoMite forum post immediately after it went up!

TheBackShed.com - Forum

There’s not even a mention of it on the PicoMite page, though the download does include binaries for all the official platforms with RC11 in the names.

I’m hoping the PicoMite devs continue to do source releases. I’ve heard they were annoyed that Clockwork used their stuff without asking, and that whole thing was handled poorly. I think it’s a cool project and the PicoCalc is an interesting platform for it. Totally understandable if source only comes at major stable releases though. Might be less chaotic for everyone that way!

It would also be good at some point to try to get the PicoCalc specific changes merged into the mainline code, if possible. But the makefile would need to be modified. I blocked out the code changes in other files with #ifdefs, unlike the initial PicoCalc release, so the PicoCalc specific stuff is isolated. But I’m also not convinced that the PicoCalc code is ready and stable anyway, since there’s one known bug with the keyboard handling, and potentially others that haven’t been discovered yet. I have a potential fix for the keyboard issue though, which I just need to test a little more and then I’ll update my repo.

I just got the keyboard error

Hi @adcockm,

The repository you have forked from GitHub - UKTailwind/PicoMiteAllVersions: This contains files to build MMbasic to run on both RP2040 and RP2350 is the official PicoMite source repository.

HOWEVER the maintainer (Peter Mather) does not use github for his own source-control purposes, just as a means of publishing the source-code to the community. This means it is often a couple of days out of date compared with the binaries he shares on TheBackShed.com - Forum.

I’m hoping the PicoMite devs continue to do source releases. I’ve heard they were annoyed that Clockwork used their stuff without asking, and that whole thing was handled poorly. I think it’s a cool project and the PicoCalc is an interesting platform for it. Totally understandable if source only comes at major stable releases though. Might be less chaotic for everyone that way!

I believe that despite the “issues” the PicoMite source-code will continue to be shared, and more often than stable releases … you’ll have noticed the github repo doesn’t even tag those .. or anything … I have tried to persuade Peter, but … ;-).

It would also be good at some point to try to get the PicoCalc specific changes merged into the mainline code, if possible. But the makefile would need to be modified. I blocked out the code changes in other files with #ifdefs, unlike the initial PicoCalc release, so the PicoCalc specific stuff is isolated.

I think we will have to wait for the smoke to die down and for ClockworkPi to respond to recent requests to make some more changes for license compliance. Then if you ask Peter very nicely, and ClockworkPi are very apologetic (and send him and Geoff a couple of complementary devices?) then maybe this will happen … or maybe it won’t, maintaining the PicoMite is Peter’s hobby, he asks for no money and refuses it when offered. If nobody pays the piper then he gets to call his own tune.

I hate to be preachy (who am I kidding, I can’t help it ) but just because we don’t pay for Open Source Software doesn’t mean we can ignore its license conditions, fair attribution is often all these hardworking people ask for, so we should provide it.

Best wishes,

Tom

[thwill]

I’ve heard they were annoyed that Clockwork used their stuff without asking, …

Not quite correct. “Not asking” is permitted (though IMO “bad form”), the issue is using it without complying with the license under which it is published. Anyway I’m hopeful it was an oversight and we can all play nicely .

Best wishes,

Tom

[Laika]

Hello, would you be able to compile a bin using this person’s custom linker? GitHub - adwuard/Picocalc_SD_Boot: Bootloader that loads firmware from PicoCalc's SD card Slot.

It should be a relatively drop-in change, and allow usage with the launcher utility. I would greatly appreciate it if it is possible!

[Toml_12953]

It’s already compiled. It’s in Picocalc_SD_Boot_main/prebuild_output/pico and it’s called picocalc_ssd_boot_pico.bin. If you want to transfer it to your PicoCalc directly, use picocalc_ssd_boot_pico.uf2.

[adcockm]

I thought I finally fixed the keyboard disconnect issue. I tested the WebMite version on PICO2W, and didn’t see it appear after running lots of BASIC programs and just letting the device sit and drain battery for a long time, over several power cycles. And literally as I was typing this, I looked over at my PicoCalc and I saw a screen of scrolling “I2C Keyboard not responding” messages. So I guess it’s still a problem. I’ll update the release notes and add a warning, but I’ll leave the builds up since people may still want to play with them.

@Laika I built with the SD_Boot modification, and have included that as well. I’m guessing it will also have this keyboard disconnect issue though.

The new release is here:

Release PicoCalc PicoMite V6.00.02RC9_c · madcock/PicoMiteAllVersions

[adcockm]

@Laika, I installed the SD_Boot loader, and it works for the included demos on the Pico, but when I loaded my PicoMite binary I just got a black screen.

In my CMakeLists.txt, I uncommented the set(SDBOOT true) at the top of the file, and used set(COMPILE PICO), which should have buillt the usual PICO firmware and then added the necessary linker option which is at the bottom of the file.

I don’t see any mention of memmap_sdcard_app.ld in the output though, so I’m not sure if that’s being used or not.

[adcockm]

An updated release for V6.00.02RC17 is available here, with a timing fix for the keyboard disconnect issue which had been plaguing the updated releases (it was something I missed when merging in guu’s changes), and some keyboard mapping fixes (which aren’t in the older official PicoCalc release).

I haven’t tested the bootloader on Pico for a while, but I’m guessing it still has the problem I mentioned above. @Laika do you have any thoughts on that? I used the same version of the memmap_sdcard_app.ld and I think I pointed cmake to it correctly? Also, I haven’t been keeping up with the bootloader progress. Does it also support Pico2 now? If so, I’d be happy to build for that as well, assuming I can get it to work.

[adcockm]

Since I’ve been tiring of having to press the physical button inside the PicoCalc case every time I want to upload a new firmware while testing, I decided to look into a software option instead…

Here’s an experimental build, with a new MMBasic OPTION I added. I tried to do it cleanly, but it’s still a bit of a hack.
Webmite for Pico2:
http://ffauploads.com/WebMite_WEBRP2350_V6.00.02RC17_USBBOOT.uf2
PicoMite for Pico:
http://ffauploads.com/PicoMite_PICO_V6.00.02RC17_USBBOOT.uf2

This can’t be used from inside a program (which wouldn’t make sense anyway), but from the prompt if you enter:

OPTION USBBOOT

then the PicoCalc will go into the firmware loading mode. If you then connect the USB cable to your PC, it should be mounted as a drive (just like if you had the device powered off and then pressed the button inside while powering on). Copy the new firmware over as usual, and when it’s done, disconnect the PicoCalc and power it off. When you power it back on, you should be good to go with the new firmware.

Source changes are here.

I’ll include it in the next release unless anyone is opposed to it.

[thwill]

For reference on the Colour Maximite 2 there is a command UPDATE FIRMWARE rather than an OPTION for this purpose.

Also note that you can force a Pico (that already has existing PicoMite firmware installed) into boot loader mode by connecting a serial terminal at 1200 baud, so on Linux when I want to upload firmware I issue the command:

screen /dev/ttyACM0 1200

Best wishes,

Tom

[cjstoddard]

I have been waiting for a functioning version of WebMite, so thank you very much. I loaded your new firmware about an hour ago and so far it is working perfecting. I was ignoring the DEL key issue, so it is a nice bonus that it is now working.

[adcockm]

As it turns out, UPDATE FIRMWARE is in PicoMite as well. Thanks for pointing that out!

I just tried it on the PicoCalc and it worked fine. I’ll get rid of my hack. I guess I should have RTFM!

[thwill]

Whilst you are “messing” with the firmware there is a persistent OPTION PLATFORM which usually defaults to the empty string, I would suggest that you change it to default to "PicoCalc", that way a program can use:

If Mm.Info(Option Platform) = "PicoCalc" Then ...

To implement PicoCalc specific behaviour.

At the moment I am working on a program that needs to do this and am checking MM.HRes and MM.VRes for the purposes of identification.

YMMV,

Tom
