A little HELP!!

[Ramius]

Hi Aerostar!
I had thought that this was the character size:

WDATA = %0001000011110000 '4 PIXELS HORIZ AND VERT !
GOSUB Send ' Zoom ADDRESS 12

So I changed it to: WDATA = %0001000000000000 and it made no difference in the text size!

I would also be curious if your setup displays actual red characters as mine seems like a light pink.

Here is a picture of my board

Actually the zoom was already set at minimum.

Not played with colour oops sorry color!! but Never Twice Same Color sets have a HUE/TINT control that you can alter on the screen.

I now have worked out getting all lines on screen, it is combined with position and line characteristics. Removed the border area around the characters

Here are the values I have used to get the attached picture.

WDATA Values to be changed to values below

In init routine

'-------------------------------------------------------------
WDATA = %0001001100001111 ' was %0001 011111 001111
GOSUB Send ' Position ADDRESS 15 *****
'-------------------------------------------------------------

and in this

FOR ICOUNT = 0 TO 10
WDATA = %0001000010000001 '<<<<<$10c4 originally
' WDATA =%0001000010000111
GOSUB Send
NEXT ICOUNT

that should! sort the screen out.



Quick and dirty code to do screen fill as a subroutine - modified CLS routine

Run it with no external video input

This is where I put the call, once it has done the Xs it will not go further remeber to comment out GOSUB HEADER.

LOOPER:
    'GOSUB HEADER    ' LINE 3 RIGHT HAND SIDE TEST.
    GOSUB FILLSCREEN
STOPHERE:
    GOTO STOPHERE

I put this at the very bottom of current code.

'----------------------debug fills screen with X------------------

FILLSCREEN: 
    'character=$0B       'SPACE
     TEMP1=0   ' LINECOUNTER
     TEMP =0    'CHARCOUNTER
loop2a:
    
	WDATA = 0  ' LINECOUNTER*256 + CHARCOUNTER   ADDRESS
    GOSUB Send
    

LOOP3a:    '                :CHARACTERS 100011       
	WDATA = %0001011100100011  '     X CHARACTER
    GOSUB Send
	TEMP = TEMP + 1
	IF TEMP >= 28 THEN
    TEMP = 0
    TEMP1=TEMP1 + 1
	ENDIF
	IF TEMP1 >= 11 THEN SCREENBLANKA
 	
    GOTO LOOP3A
    
SCREENBLANKA:
	RETURN

Had a play with colors -I found that reducing the drive in the MODE REGISTER, BIT M5, from 6dB to 0dB improved the colours, so M5 needs to be a 0, this will depend on how good the monitor is..



If you mofify the fillscreen to the following you should get lines of ifferent colors.

FILLSCREEN: 
    'character=$0B       'SPACE
     TEMP1=0   ' LINECOUNTER
     TEMP =0    'CHARCOUNTER
loop2a:
    
	WDATA = 0  ' LINECOUNTER*256 + CHARCOUNTER   ADDRESS
    GOSUB Send
                                             

LOOP3a:    '                :CHARACTERS 100011       
	WDATA = %0001011100100011  '     X CHARACTER
'   WDATA = %0001011101110111
'    if temp1 =0 then WDATA = %0001011101110111
    if temp1 =1 then WDATA = %0001000001100011
    if temp1 =2 then WDATA = %0001000101100011
    if temp1 =3 then WDATA = %0001001001100011
    if temp1 =4 then WDATA = %0001001101100011
    if temp1 =5 then WDATA = %0001010001100011
    if temp1 =6 then WDATA = %0001010101100011
    if temp1 =7 then WDATA = %0001011001100011
    if temp1 >=8 then WDATA = %0001011101100011
    
    GOSUB Send
	TEMP = TEMP + 1
	IF TEMP >= 28 THEN
    TEMP = 0
    TEMP1=TEMP1 + 1
	ENDIF
	IF TEMP1 >= 11 THEN SCREENBLANKA
 	
    GOTO LOOP3A
    
SCREENBLANKA:
	RETURN

Wow! This is really so great! Thank you! I will try the above code just as soon as possible. I loved your screen full of "X's"! If I understand things correctly the text is as small as it can be? FYI, I work at Fox Television so a high quality professional monitor is not difficult to bring home. Did you like how I built the board with the chip? This display is something I have been dreaming about for several years now and it is so wonderful to finally see some light at the end of the tunnel! I also believe the research and development is a major contribution for all others!

Best, Ed

Board looks great - There is still a demand for analogue OSD despite all the digital stuff around. The chips were hard to find after they had been discontinued, but your find of supplier seems to have lots still, price is good, Ebay prices .... silly.

What are you going to this it for ?, I am guessing at RC aeroplane or boat, video from it and motor speed from port and starboard propulsion units.

[Ramius]

Yes, you are right on! I have an RC submarine called a Typhoon just like the one in my avatar. My first pic project was an electronic compass as you cannot use GPS underwater. A representative from China was going to buy compasses from me and said my compass was too precision as it is accurate to 1/10 of one degree. They only wanted to pay for 1/2 of one degree accuracy. At one point it seemed they only wanted the design and software so I published the information thus putting it in the public domain. The sub has twin drive motors with temperature sensors mounted on the. There is also a roll and pitch sensor, angle sensors on the bow planes, stern planes and rudder. A sensor for speed and another for depth. There is a sensor for battery voltage and current draw. A laser pointer has been added to the "sail" for targeting. The periscope is 3 mm in diameter and about 2" long with a first surface mirror at the top sending picture down the tube through some acromat lenses then a dove prism lens to reverse the image left to right to avoid using a second mirror. Below the dove prism lens is a "snake camera" which is 3/4" square pointed up the periscope. Since it is a small size it is able to pan left and right. One of the larger challenges was being able to transmit video from underwater. With a "strange" antenna configuration video could be transmitted from a depth of 1 meter, possibly more as my Jacuzzi is only 1 meter deep. There are also torpedoes and missiles fueled by compressed air. Others had used Estes rocket motors until one guy fired a missile from his swimming pool, it broke surface tension, make a left turn, cleared the fence, when through a screened in patio, and set fire to a couch that his neighbor was taking a nap on! Since this, we have all gone to compress air. My torpedoes have an optional nose cone made from a foam paint brush soaked in water color the dried. When these torpedoes are fired they leave a small orange trail and a large orange dot on whatever it hits (like duck butts!) So there are a lot of features and sensors that would be great to display the readings of. Okay, that's the basics.

Must admit, I did not know about RC Subs, sounds great. Loved the bit about the guy and his rocket and neighbour !
