Add Machine.set_memory_broadcast() for the unicast memory-snapshot stream - #13
Merged
Conversation
Wrap the firmware's authenticated /api/memory/toggle-broadcast route so
clients (like Memory Mapper) can turn the live SRAM broadcast on and off
without reaching for Machine.call(). Enabling takes a frequency_ms
clamped to the firmware's 10-60000 ms bounds; disabling sends
{"enable": false}. Documented in docs/memory.md and covered by the
wrapper-route table plus a body/clamping test.

The firmware no longer broadcasts memory snapshots to the whole network (vector#369); it streams to a single target IP, defaulting to the requesting client. Add the optional ip= parameter to set_memory_broadcast() and update the docs to describe the unicast behavior, including the USB caveat where ip must be passed explicitly.

Summary
Adds a
Machine.set_memory_broadcast(enabled, frequency_ms=100, ip=None)wrapper for the firmware's authenticated/api/memory/toggle-broadcastroute, so clients can turn the live SRAM UDP stream (port 2040, 4-byte offset header + up to 256 data bytes per packet) on and off without reaching forMachine.call().ippicks the target explicitly; when omitted, the firmware streams back to the requester — usually exactly right, since the listener typically runs where the code runs. Over USB there is no requester IP, soipmust be passed.{"enable": true, "frequency_ms": N}(+"ip"when given) withfrequency_msclamped to the firmware's 10–60000 ms bounds; disabling sends{"enable": false}._call_gatedso a missing route on old firmware raisesUnsupportedFirmwareErrorwith the firmware version named.docs/memory.md(new "Live snapshot streaming" section) and covered by the wrapper-route table plus a body/clamping/ip test.Motivation: memory-mapper#31 needs to start the stream on machines the user selects; this gives it (and anyone else) a proper API instead of a raw route call.
