Is there any simple way to go? such as PORTIO under Windows...

How fast anyone already got it?

By the use of TERMINAL demo program, I got 10ms delay, that's MenuetOS's 1/100s round time. How can I improve it?

Many thanks for any help...

I use m076p50, it seems MeOS begin to offer safety I/O

I hope MeOS can be a hardware enginners friendly OS, only because I'm a hardware enginner, ^_^

Thanks for you great work, and to all the developers

Cool, a hardware engineer Smile.

Imagine buying a modem - little windows logo, a penguin, and then a 'MenuetOS friendly' sticker too and a MeOS driver on the CD =). Or an SBC with 'MenuetOS on ROM' written onto it =) a PDA?. I can dream of a thousand products =).

If you are an asm programmer, i think theres some info about IO ports in SYSFUNCTS.TXT.

'Menuet Inside' =)

You say right, Sir....

I didn't like complex OS, nor simple but poor graphic ability

Complex OS mean hard work, poor looking mean no one will like what else I do..., so, I like MeOS

hehe,...I'll try to build a digiscope, a PDA like scope, or a scope like PDA, that's my dreem. I need speed, speed mean real time waveform or wavedata I can process...hehe

We now have control of our PLC modules and CNC machine working off Lpt1 and Lpt2.


Fantastic OS.

Sure are having good times making things work with Menuet.


The lights ! They are blinking !! Yippie. Yahooo.

jep,
i made some serrial drivers for menuet its a side produkt of my work,

the delay is okay but we have to read each byte for the bits and than doing some delay time between the bits than calculating the time.

Its mostly used by lcd driver written in asm but its hard to find some good source stuff about that.

I will post my source soon. Suggestings about serial and IR interface and even LCD display driver are welcome

thanks and keep going with that OS there should be more work on tex editors and stuff like that for faster coding.

hmm
download the LCD datasheet and you will know how to program it,
comrade: LCD is liquid crystal display,
usually used with microcontrollers.
google on http://www.google.co.hu/search?q=HD+LCD+hitachi+2x16&btnG=Keres%C3%A9s&hl=hu
or
http://www.google.co.hu/search?hl=hu&q=%22Hitachi+HD+44780%22&btnG=Keres%C3%A9s&meta=

btw to the topic question:
MEOS doesnt allow direct i/o?
Code:
in al,dx
out dx,al

Menuet allows direct IO. You must first enable it. See file rtdata.asm at floppy.
