<h2>Screen Behavior & Refreshing</h2>
|
|
|
|
<div class="Row v">
|
|
<p>
|
|
The initial screen size, title text and button labels can be configured
|
|
in <a href="<?= url('cfg_term') ?>">Terminal Settings</a>.
|
|
</p>
|
|
|
|
<p>
|
|
Screen updates are sent to the browser through a WebSocket after some time of inactivity on the communication UART
|
|
(called "Redraw Delay"). After an update is sent, at least a time of "Redraw Cooldown" must elapse before the next
|
|
update can be sent. Those delays are used is to avoid burdening the server with tiny updates during a large screen
|
|
repaint. If you experience issues (broken image due to dropped bytes), try adjusting those config options. It may also
|
|
be useful to try different baud rates.

<h3>UTF-8 support</h3>
|
|
|
|
<p>
|
|
ESPTerm supports all UTF-8 characters, but to reduce the screen buffer RAM size,
|
|
only a small amount of unique multi-byte characters can be used at the same time
|
|
(up to 160, depending on compile flags). Unique multi-byte characters are stored in a
|
|
look-up table and are removed when they are no longer used on the screen. In
|
|
rare cases it can happen that a character stays in the table after no longer
|
|
being used (this can be noticed when the table fills up and new characters
|
|
are not shown correctly). This is fixed by clearing the screen (`\e[2J` or `\ec`).
