Bit 0 of efuse_rd_disable[3:0] is mapped to BLOCK1 this bit is at position 16 in EFUSE_BLK0_RDATA0_REG

Returns True if an address starts in the irom region. Valid for ESP8266 only.

List root files from a .bin that may be LittleFS or SPIFFS. Tries LittleFS first (with given or default partition offset/size), then SPIFFS.

Challenge-response login: GET login.html, POST auth. Returns None on success, error message on failure.

Challenge-response login: GET preauth from login.html, compute SHA256(user:preauth:password), POST to login.

If SHA256 digest of the ELF file needs to be inserted into this segment, do so. Returns segment data.

Handle file selection and load its content.

Walk src_dir and create a LittleFS v2.0 image at image_path. disk_version=0x00020000 forces the on-disk format to LittleFS v2.0, which is wha

Parse one IMPROV packet line (with or without trailing \\n). Returns (type, data) or None if invalid.

Parse binary partition table. Returns dict name -> (flash_offset, size). Stops at 0xFF*32 or when data runs out. Skips 32-byte blocks that st

After init: move root CSV files (except mypos.csv) into YYMM folders based on file mtime */

Replaces the content of a specific block in the in-memory content, ensuring the block name line is not duplicated. :param blo

Resolve host (IP or mDNS) to IP. Return (ip, error_msg).

Resolve file_or_dir to a list of SD paths to fetch. If it names a file, return [path]. If it names a directory, return all files under it.

Rotate the bitmap data for each character from row-major to column-major order and flip it horizontally by adjusting the row indexing

Save a set of V1 images for flashing. Parameter is a base filename.

Save the next segment to the image file, return next checksum value if provided

Write packet to serial and flush.

Return a new ImageSegment which splits "split_len" bytes from the beginning of the data. Remaining bytes are kept in this segment obj

Read a LittleFS image file and extract all files to dest_dir.

Update the size of the drawing area.

Update the frame surrounding the drawing area.

Update the layout to center the fixed-size object in the available space.

Check that partition table fits into the given flash size. Raises InputError otherwise.
