A board file for the Elecrow CrowPanel 7.0" (DIS08070H, ESP32-S3-WROOM-1-N4R8): 800x480 through mipi_rgb, GT911 on the ESP32-S3's USB pins (elecrow_usb_phy.h frees them, behind a flag only this board sets), the Guition's vertical sizes across a wider page, no rotation. Its 4 MB of flash take the CYD's budget: a partition table of the component's (smart_display: partitions: 4mb_wide_slots, 1,984 KB slots), the icon fonts at 2 bits a pixel and the TLS client only bring the firmware to 1,865,440 bytes, 91.8 % of a slot, with camera images kept. docs/ELECROW.md has the numbers and the trade. The add-on reads a large board's name from the type sensor's value, the editor offers the board under New screen and draws the wide preview, tools/check.sh builds it with the budget, render_topbar and capture_ui take the panel's size. Firmware 0.2.79; the CYD image is unchanged (1,633,760 bytes). This fork builds from gittea.trippedonmy.name/Xandrossian/homeassistant_espscreen: the packages, the fonts, the component and the add-on repository point there instead of GitHub.

"""Partition tables a board file can ask for with `smart_display: partitions:` (firmware 0.2.79).

ESPHome's own table for 4 MB of flash keeps 448 KB for NVS and gives the two update slots 1,792 KB each. The screen's
|
|
preferences take a few KB of NVS (ESP-IDF's own two-slot example keeps 16 KB), and the Elecrow CrowPanel 7.0" needs
|
|
the room: its firmware is the Guition's, which does not fit 1,792 KB. The tables live here, as text, because a board
|
|
file over GitHub cannot carry a file of its own; __init__.py hands the chosen one to ESPHome as the build's
|
|
partitions.csv. A table never changes once a screen is flashed with it: an update over Wi-Fi writes into the other slot
|
|
of the table the screen has, and only a USB install lays the flash out anew.
