Hey there everyone, LBPHacker here again.
This is going to be a quick one, the save itself is pretty self explanatory.
2012356View Save 2012356So this is a text screen for my computer with
- 32x24 characters
- Movable cursor (automatically advances when a character is written)
- 4-bit foreground and background colour
- Downward scrolling
The communicaton protocol:
- 0x00cc: write character [cc] at current cursor position, advance cursor
- 0x1ppp: set cursor position to [ppp] (ppp is a 10-bit value, its lowest 5 bits are the X component and the highest 5 bits are the Y component, valid in [0x000, 0x2FF])
- 0x20bf: set background colour to [b] and foreground colour to [f] (b and f are 4-bit values, bits from highest to lowest order: intensity, red, green, blue)
- 0x3000: scroll down by a single line; discard the topmost line and fill the space at the bottom with spaces using the current background colour (you'd have to send 24 of these to clear the screen)
2013253View Save 2013253This thing above is the same with a keyboard, which
- Has Shift and Caps lock (Shift turns off automatically after modifying a single key)
- Sends simple character codes (not keycodes) when a key is pressed depending on Shift and Caps lock state

can you give the source code in the save program for studying?

Does the assembler use decimal or hex? I've never used assembly language before.

I agree with GunPowder can we get the examle source for refrence? For those who want some refrence now heres a script by SopaXorzTaker (I did NOT make this)
https://gist.github.com/SopaXorzTaker/26fcc318bdc3781727ba748ccb3194ff
EDIT:
Well I just noticed something in that script if you use the printInt function add the line
decimals: dw "0123456789"
to the bottom of your script

Hold on, I'm not sure how much good uncomment assembler code will do. Now they are commented.

Thanks for the code that helps imensily :D
Just one question how do you encode the cursor postion? (Or any of the numbers above) Im new to hex, I found a converter online but im not sure how to imput the numbers correctly it always messes up some how...
Holy (Censored) I Fgured It Out! Heres A Tutorial For Newbies (LbpHacker If You See This Add It To Your Post Nobody People Like Me Don't Understand It)
So Heres What To Do
- Go To An Online Decimal To Binary Converter (I Use http://www.binaryhexconverter.com/decimal-to-binary-converter) And Imput Your Y Value For This Example I'll Use 5 It Converts To 00000101
- Now Remove Extra Zeros From The Front So There Are Only 5 Numbers In Our Example's Case It Will Look Like This 00101
- Now Repeat Steps 1 and 2 But With Your X Value For The Example We Will Use 6 (Wich Becomes 00110)
- Now Go To A Binary To Hex Converter I Used (http://www.binaryhexconverter.com/binary-to-hex-converter)
- Next Put The Y's Binary First And Add The X's To The End For The Example It Would Look Like This 0010100110
- Finaly Convert It And The Hex Value Outputed Is Your Cursor Pos, In Our Example's Case The Code Is A6 Wich Turns Into 0x10A6 (Simply Add 0x1 To The Front, However Be Carefull If The Hex Code Has Less Than 3 Digits You Must Add 0's To The Front To Make It Three Long Here's An Example: Raw Hex Is A Wich Would Become 0x100A)
I Hope This Helps It Confused Me Pretty Much All Day While I was Trying To Write A Calculator Program (You Can Expect To See It Out Some Time This Week :D)
