Lower Resolution (20x8?) Text on TV??
I've been studying and fiddling around with the TV_Text object.· I like that it uses the built-in fonts and very little RAM for program and data.· I like that the color can be specified for each character.· I have even got it going using 16 different colors.
However, the text is way too small and hard to read on my tiny 2.5" TV Parallax TV screen.
Could this concept to extended to put less characters on the screen so that they can be larger and easier to read on small screens?· Something·in the neighborhood of·20 columns by 8 rows would be fine for my purposes.
I know that the TV Graphics object can do text of different sizes, but there is WAY too much overhead involved with this just to display simple text.

Just set cols=20, rows=8 in the CON section of TV_Text and you have a 20x8 character display.
Then set hx=8, and vx=2 in the DAT section (tv_params) to stretch the display to the whole screen.

This really can be, though it would be an idiotic feature an a 240 line monitor. It will be much better just to use the upper OR lower field. Which however would not work without internal memory...
Since I only want to use the 20x7 arrangement in color, I have been triming down the code to be specifically for this. I have played with color combinations to get 8 colors that look good and then made inverse versions (black on colored background) for a total of 16 color possibilities for each character on the screen.
Thanks to whomever wrote the original TV_Text and to deSilva for the mods.

Any chance we can get you to share your final code?
Looks great!

My reason for avoiding colour definitions with "chroma-on" in the MPE_TEXT driver was just that colour will decrease the display quality ... I am still experimenting with chrystals... 5 and 10 MHz are not really good...
