Parse ANSI and emit only ('insert', text, tag). Escapes become [EL], [SGR:31], etc. No erase handling.

Preprocess the file to track global settings for each block.

Process one chunk. Returns 1 if status line started with "HTTP/1" (caller sets IDLE), 0 otherwise. */

Abbreviate path for display: show last component if long.

Add YYMM to dirsTouched if not already present. Returns 1 if added. */

Return (base_url, error). base_url is http://IP/.

Build IMPROV packet: header + type + len + data + checksum + \\n.

Calculate checksum of loaded image, based on segments in segment array.

Return list of SD paths (file or dir/file) for all files under dir_path.

Return a new ImageSegment with same data, but mapped at a new address.

Derive a default output name from the ELF name.

Pack 8 rows of 5 bits each into 5 bytes, bit by bit.

Use serial access to detect the chip type. We use the UART's datecode register for this, it's mapped at the same address on ESP8266

Return a/b rounded up to nearest integer, equivalent result to int(math.ceil(float(int(a)) / float(int(b))), only without possible floating p

CRC32 algorithm used by 8266 SDK bootloader (and gen_appbin.py).

Any argument starting with "@" gets replaced with all values read from a text file. Text file arguments can be split by newline or by space.

Slice a full backup .bin at the given flash_offset and extract the LittleFS filesystem. The backup file is produced by read_backup() which reads

Extract filesystem from a backup .bin to dest_dir. Tries LittleFS first, then SPIFFS. Returns (True, None) or (False, error_msg).

Fetch download.html and parse (display_name, full_url) for full-image rows. Return ([(display, url)], error_msg).

Download each path via GET base_url + "sd/" + path into outdir. progress_cb(current_index, total) optional. Returns (saved_count, list of

set fixed position based on config

Start downloading compressed data to Flash (performs an erase) Returns number of blocks (size self.FLASH_WRITE_SIZE) to write.

Return the size that partitions will occupy in flash (ie the offset the last partition ends at)

Generate the C header text for a single-character GFXfont. - char is the glyph character ('A' by default). - We use a simple metric setu

For flash encryption related commands we need to make sure user has programmed all the relevant efuse correctly so before writing enc

Read partition table from a .bin file. Assumes file byte 0 = flash_base (e.g. 0x1000 for full backup). Reads at file offset (0x8000 - flash_b

Convert a string which might be numeric or the name of a partition subtype to an integer

Read the app partition from a .bin file and search for a version string. For full backup images: read from file offset 0xF000, size 0x140000.

unix time stamp from date and time info in frame.
