b544cf2ffe [ld2410] Batch UART reads to reduce loop overhead 2026-02-06 23:39:31 +01:00
J. Nick Koston
6d1281301f [ld2412] Batch UART reads to reduce loop overhead 
Read all available bytes in batches via read_array() instead of
byte-at-a-time read() calls. Each read() internally chains through
read_byte -> read_array(1) -> check_read_timeout_ -> available(),
resulting in 3 UART calls per byte. Batching reduces this
significantly.

901192cca1 [ld2450] Batch UART reads to reduce loop overhead 
Read all available bytes in batches via read_array() instead of
byte-at-a-time read() calls. Each read() internally chains through
read_byte -> read_array(1) -> check_read_timeout_ -> available(),
resulting in 3 UART calls per byte. At 256000 baud with ~235 bytes
per loop iteration, this was ~706 UART operations per loop call.
Batching reduces this to ~12.

Measured 33% reduction in loop time (2348ms -> 1577ms per 60s).

96289775f2 [i2c] Replace switch with if-else to avoid CSWTCH table in RAM 
Replace the Wire status-to-ErrorCode switch with if-else to prevent
the compiler from generating a 6-byte lookup table in DRAM on ESP8266.

3e4269d32a Address review: add SSD1306_MODEL_COUNT sentinel and bounds checks 
- Add SSD1306_MODEL_COUNT sentinel to enum for compile-time table size validation
- Replace 14 individual static_asserts with table size checks against SSD1306_MODEL_COUNT
- Add bounds checks in get_height_internal()/get_width_internal() to preserve default return 0

8da986d41a [ssd1306_base] Move switch tables to PROGMEM with lookup tables 
Replace three compiler-generated switch tables (CSWTCH) with PROGMEM
lookup tables, saving 84 bytes of DRAM on ESP8266.

- model_str_(): 56B string pointer table → PROGMEM_STRING_TABLE
- get_height_internal(): 14B byte table → PROGMEM struct array
- get_width_internal(): 14B byte table → PROGMEM struct array

Width and height use a single ModelDimensions struct array for
maintainability. All 14 enum values verified with static_assert.

a9a943b858 [mqtt] Add zero-allocation topic getters to MQTT_COMPONENT_CUSTOM_TOPIC macro 
Add _to() variants that write into a stack buffer and return StringRef,
avoiding heap allocation on every publish. Update publish_state() in
climate (11 allocations eliminated), fan (3), cover (2), and valve (1)
to use the new stack-based getters.

The allocating getters are retained for setup-time paths (subscribe,
send_discovery, dump_config) where the allocation is one-time.

664baac09e [mqtt] Avoid heap allocation in on_log by using const char* publish overload 
The on_log callback was constructing a temporary MQTTMessage struct which
copied the log_message_ topic string and created a new std::string from
the message buffer on every log line. This is called frequently at runtime
and contributes to heap fragmentation.

Use the const char* publish overload directly to avoid both allocations.
