# 0x606E 位交换自动化测试 — 经 RP2040 注入器
|
|
# ============================================================
|
|
# 流程: 读基线 -> 写各交换位并校验 -> 读回确认 -> 收尾还原
|
|
# 注意: LA1010 波形对照按 doc/architecture/rgb_bit_swap_test.md §1.1 手工比对;
|
|
# 本脚本负责寄存器侧的全部操作与校验, 打印每步期望的 LA 现象。
|
|
# 用法: python bitswap_auto.py [COM口]
|
|
# python bitswap_auto.py COM9 full 额外跑 G 通道(0x40)与 R 通道(0x20)
