Double Vision Arduino Upgrade | 18 August 2023 |
The Arduino Uno takes the place of the ZX-81 and allows Double Vision to be used with a Terminal program on a PC.
White Block on Black Background 9" away, eye spacing 2.6".
Taking the column with the highest brightness,
Left image of block is offset 4 pixels from Right image, at 4deg/pixel =16deg.
With 2.6" eye spacing 16 deg =9.3" distance. ->Satisfactory, most satisfactory[1]
Left Right

[S] - Save behaviour as default
[r][0-9] - pixel resolution degrees (7)
[b]<1-64>[,] - set to brightness of scene
[a] - auto set brightness of scene
[t][l] - print brighter than threshold
[d] - print darker than threshold
<0-16>[,] - threshold for printing values
[p]<0-64>[,] - number of servo pulses between pixels when scanning
[y][+]<0-15>[,] - maximum row in scan
[-]<0-15>[,] - minimum row in scan
[x][+]<0-15>[,] - maximum column in scan
[-]<0-15>[,] - minimum column in scan
[a][1-8] - Act to autorun on power on
[0] - no autorun
[d] - if Playing ends, run autorun Act
[v] - verbose printing
[q] - quiet printing, verbose off
System
------
[*][r][0 1-8] - record act, 0 use page0
[l][0 1-8] - load act, 0 use page0
[c][0 1-8][0 1-8] - copy act to act, 0 use page0
["] - start/end of a comment, processed in GetCcmnd()
Print
-----
[?][?] - prints all acts
[a] - prints all acts
[0] - prints acts 0, and changes [?][?] to just print current page
[1-8] - print Act in current page
[b] - print behaviour
[B] - print EEPROMbehaviour
[d] - dump all acts to PC without descriptions, for reloading
[h] - print help
[E] - print EEPROM use
