- LEGACY/remote/teensy/: old remote sketch from https://mangavalk.com/Hexapod/remote.git @ 492dece (reference only). - remote/Config.h: sticks on A0-A5, Nextion on Serial1 (0/1), as in the old sketch; MPU6050 moved to Wire2 (25/24) since A4/A5 are Wire's pins. - NextionUI: controls on a vscope-global "control" page added to the old HMI; keeps the old t1 status texts; the old page-1 b2 button (and serial 'U') enter Nextion upload passthrough, following the PC's baud. - Docs: NEXTION.md, remote README wiring, CLAUDE.md.

// Nextion serial HMI driver. No Nextion library - the protocol is small:
|
|
//
|
|
// Nextion -> remote: custom frames the HMI's touch events send with printh:
|
|
// '#' <len> <cmd> [value] e.g. printh 23 01 41 (ToggleArm)
|
|
// printh 23 02 56 + prints hSpeed.val,1
|
|
// Command bytes are listed in NEXTION.md and in NextionUI.cpp.
|
|
// Native Nextion return frames (terminated FF FF FF) are also parsed: a
|
|
// display reset (0x88 "ready") triggers a full redraw, and the old HMI's
|
|
// upload button sends a standard touch event (0x65) that's recognized.
|
|
//
|
|
// remote -> Nextion: plain instructions ("bArm.txt=\"ARMED\"" + FF FF FF).
|
|
//
|
|
// The remote is authoritative: buttons are plain buttons (not dual-state),
|
|
// they only send requests, and render() repaints whatever the remote state
|
|
// actually is. A Nextion reboot or a dropped byte self-heals on the next
|
|
// periodic full refresh.
