Quad Alphanumeric display shows extra top bar after messages "No." and "No. "
Quad Alphanumeric display displays an extra top bar after message "No." (bar is position 3) and "No. " (position 4), using left alignment.
Might also be worth being generous and handling exclamation mark differently. It does a vertical bar, but might make more sense as a full stop / period with top half of the right side illuminated (i.e. half the bar instead plus dot)
Send Yes! then try Yes'. then Yes.', as you can see the quote isn't quite the right choice for the right side top half bar, but illustrative.
there might be something funky with the input too, it has no validation for alphanumeric components, so if you accidentally add a newline you then get a backtick (not the same issue but related - establish then pass to Loren)
Also full stops/spaces are weird, try sending 4 spaces then a period, then try 3spaces and a period.
related to these display inconsistencies: Using two left aligned 14-seg models, followed by a 7-seg model (right aligned). Two issues, the colons don't show correctly for clock on 7segment display, instead taking a whole segment slot, but period/full-stop works normally. Messages that are too short are leaving a dash on the 2nd 14-segment display, similar to reported above. There were also newline inconsistencies with the character displays, reported by Tyler, but seen myself too. Will document when seen again.
a) Messages with no extra trailing spaces on segment 2, and with colon for time in segment 3: b) "fixed version" with extra spaces for segment 2 to ensure always at least display length, and period instead of colon for time:
a) b)
*Seg1 uses slice 0,4 (truncated in screenshot).
{%- assign now_s = "now" | date: "%Y-%m-%dT%H:%M:%S" | date: "%s" %}
{%- assign now_z_s = "now" | date: "%Y-%m-%dT%H:%M:%SZ%z" | date: "%s" -%}
{%- assign server_utc_diff = now_z_s | minus: now_s -%}
{%- assign thing = 3600 | times: vars["timezone_offset_hours"] | minus: server_utc_diff -%}
{{ now_s | plus: thing | date: "%Y-%m-%dT%H:%M:%S" }}
Seeing the reboot on I2cWrite messages out of sync too. Was the XIAO, but I confused some LED thing with it actually rebooting. Has SSD1306 128x64 and a Character LCD 16x2 attached.
See it reboot after init twice then boot okay thrid time, no changes:

Summary of issues + Initial test plan:
Test Plan
Alphanum 14-segment displays
Trailing spaces
- Test 'No.' w/left alignment
- Test 'No. ' w/left alignment
- Test 'No.' w/right alignment
- Test 'No. ' w/right alignment
Exclamation marks
Might also be worth being generous and handling exclamation mark differently. It does a vertical bar, but might make more sense as a full stop / period with top half of the right side illuminated (i.e. half the bar instead plus dot)
Send Yes! then try Yes'. then Yes.', as you can see the quote isn't quite the right choice for the right side top half bar, but illustrative.
Input validation lacks newline cut off
there might be something funky with the input too, it has no validation for alphanumeric components, so if you accidentally add a newline you then get a backtick (not the same issue but related - establish then pass to Loren)
Full stops / Periods + Spaces are weird
Also full stops (periods) and spaces are weird, try sending 4 spaces then a period, then try 3spaces and a period.
Messages that are too short leave a trailing dash
https://github.com/adafruit/Adafruit_Wippersnapper_Arduino/issues/768#issuecomment-3096792840 Messages that are too short are leaving a dash on the 2nd 14-segment display, similar to reported above.
7-segment displays
colons (clock separator) not displayed correctly
Consumes a character space (vertical dashes) instead of using the built-in clock digit separator segments (colons). "the colons don't show correctly for clock on 7segment display, instead taking a whole segment slot, but period/full-stop works normally."
trailing dash with lines shorter than character limit
Messages that are too short are leaving a dash on the 2nd 14-segment display, similar to reported above.
LCD Character displays
Newline inconsistencies
There were also newline inconsistencies with the character displays, reported by Tyler, but seen myself too. Will document when seen again.
OLED displays
Probably all the same
A full-stop is a period '.' / denotes the end of a sentence. https://en.wikipedia.org/wiki/Full_stop
