TFMSX rev 2 features & problems

[NYYRIKKI]

Ouch... I found another problem from my machine... I was wondering why I can't make my machine to boot on MSX2+ mode. On Friday I received my PLCC32 adapter, so today I took a closer look of the problem and it seems that the boot logo code was missing, that caused TFMSX to crash on boot. How ever the bigger problem is that there is no enough space to fix this due to fact that last 16kB of the dip selectable 64kB block seems not to be mapped to MSX memory at all!

I can understand if you don't want to support burning full KANJI-BASIC or any extra stuff like BASIC compiler or joystick disk drive, but it would be nice if you would have enough memory space to put even full boot logo in to the ROMs!!! For now I solved the issue by removing "M" and "S" from the MSX2+ boot logo so that you get just a big simple "X" on the memory counter / title screen. The animation is also replaced with simple fade. With this simplified logo I was able to fit all the functionality back to 48KB, but it was a very tight fit.

Here is the ROM that I wrote today to my TFMSX:
https://msx.fi/temp/NEW_TFMSX_ver1.zip

The available configs in it are:

0 MSX2 (English) with added memory counter
1 MSX2 (Finnish/Swedish)
2 MSX2+ Japanese (60Hz)
3 MSX2+ Finnish/Swedish (50Hz)

At least on MSX2+ setups I've added possibility to switch between 50Hz/60Hz during boot time by holding down "H"-key until beep.

Another thing I noticed while playing with these ROMs is that there is no RAM on bit 7 in I/O port #F4... Not a big thing at all, but likely easy to fix as well. Normally this bit is used by MSX2+ BIOS to distinguish hard boot from soft boot.

It looks that 5 keys are not mapped correctly, and some annoyingly in wrong position.

I will try to chaise which ones need to be remapped.

Need to save this program to floppy

From memory i map the full 64 as a 32K rom, 16k subrom and the final 16k is mapped as a DOS rom. This was so MSX2 could have a DOS rom. I guess DOS comes on the floppy controllers so i could put this elsewhere?

EDIT: Ops looks like i disabled mapping the dos rom.

On Ubuntu I can read codes using command xev , it displays all HID captures events.

[arkadiusz.makarenko]

New keyboard firmware : https://github.com/arkadiuszmakarenko/T ... v2F730.bin

1. Download and start STM32CubeProgrammer
2. Connect USB A - USB A cable to lower USB port on TFMSX, and remove the jumper next to usb port. Power up TFMSX.

3. Change dropdown to USB, and click connect (additional drivers might need to be installed? )

5. Power down TFMSX, set jumper again, as it was.

6. Power up TFMSX and enjoy.

Known issues
Key Select is not present on most keyboards, so it has been replaced with F6. F8 is combination of ctlr+shift+graph+code ,but I don't know how to test it.

New firmware passes above test.

Hi, @arkadiusz.makarenko

I now did manage to do the cable and tested you new keyboard driver... Close, but no cigar... You obviously ignored my last configuration file update and therefore ie. Numpad issue was not resolved and so there is still two keys on one physical key. Now also Graph & code jumped to wrong sides of space etc. I would also try to avoid using Windows-keys as they may not exist in all keyboards, but even if you use them, it makes more sense to use the right one instead of left one. Good thing is that as you managed to put "CODE" in to "Alt Gr" as this kind of proved that the scan codes in our USB-keyboards are the same, so this should not be reason for our problems.

I now fixed names on my version of config file based on your constants list. Can you please at least read it trough and compare to your implementation side by side. This is not "only right way to do it", but there are reasons why I've selected the extra keys that I have. (SELECT is usually close to STOP and so on) If you don't agree with this, we can talk about the remaining issues. Please include also your version when you change it, so that we can talk about the issues with same names.

Do you think it would be also possible to support MSX leds on the USB-keyboard? In MSX CapsLock-led is controlled by PPI port C (I/O $AA), bit 6 and Kana-lock led (could be mapped ie. to ScrollLock led) is controlled by PSG register 15, bit 7. These are both inverted, so 0=Led on, 1=Led off

@NYYRIKKI
Could you make a call if I should implement usb mouse?

As I said this is close to situation of early PCs. Many MSX2 games (like ie. Breaker Breaker) benefit if you have mouse, but you can still play without (like ie. Sierra adventures on PC)... and you can still attach a real MSX mouse if you wish... After supporting USB keyboard and joypads this sounds to me like next logical step to take, but mostly it is about how you value your time.

Ps. Your implementation of ctlr+shift+graph+code worked just fine.

[NYYRIKKI]

From memory i map the full 64 as a 32K rom, 16k subrom and the final 16k is mapped as a DOS rom. This was so MSX2 could have a DOS rom. I guess DOS comes on the floppy controllers so i could put this elsewhere?

EDIT: Ops looks like i disabled mapping the dos rom.

Yes you did and I think it would be important to get this valuable 16kB back... I saw that you put DOS-ROM in that space, but that is quite useless idea. The ROM contains the hardware routines to interact with disk, but since you don't have disk drive, having the ROM does not help, mostly just eats up drive letters & memory in case someone adds a real drive(s). Even if you plan to implement some SD-card interface or similar later, this is not the way to go... You rather like to implement Nextor as then you don't need to worry about partitioning tools, file systems, disk emulation software or such as that you get as a free bonus. You only need to provide a way to read & write 512-byte blocks... The downside is though that it will not fit to 16kB, so some new way of mapping ROM would be needed as well. Anyway, this is already getting quite a far from the topic.

On my ROM set I used the missing 16kB for BASIC compiler as it makes more sense (in case you enable this at some point). How ever the MSX2+ boot screen is what I would use it in real life, if it would be working.

@NYYRIKKI

This is my test keyboard. It is cut version, and my goal is to squeeze in all keys on it, as it is what I am planning to use with my TFMSX.

As you can see it doesn't have LEDs,so I completely forgot about them.

Ps.
I will have a look at numpad issue and your mapping suggestions later today.
