Merge branch 'master' into nomad-gemini

Nomad fixes: honor pa_fan_disabled, drop RADIOLIB_LOW_LEVEL, relocate variant
Non-PWM fan paths (main.cpp setup + enableFan) now respect pa_fan_disabled instead of forcing the fan off/on. Remove the unneeded global RADIOLIB_LOW_LEVEL build flag (no code requires it; Module low-level methods are already public). Move the variant to variants/esp32/radiomaster_nomad_gemini/ for layout consistency with sibling boards.

Thomas Göttgens	d3d606c1d5	Nomad fixes: honor pa_fan_disabled, drop RADIOLIB_LOW_LEVEL, relocate variant Non-PWM fan paths (main.cpp setup + enableFan) now respect pa_fan_disabled instead of forcing the fan off/on. Remove the unneeded global RADIOLIB_LOW_LEVEL build flag (no code requires it; Module low-level methods are already public). Move the variant to variants/esp32/radiomaster_nomad_gemini/ for layout consistency with sibling boards.	2026-06-07 10:53:41 +02:00

LittleatonandBen Meadors	6cd9a3a42b	missing module config (#10496 ) 13302 and 13300 had missing module config for slot 2, also the rf switch and voltage info was missing. Without that the auto setting in the config.yaml will try to use the default lora-hat-rak-6421-pi-hat.yaml and things do not work correctly.	2026-06-05 08:37:24 -05:00

Thomas Göttgens	f6956160bb	Unify PA fan macro: RF95_FAN_EN -> RADIO_FAN_EN The nomad branch generalized RF95_FAN_EN into RADIO_FAN_EN with enableFan()/disableFan() helpers, but master independently added new RF95_FAN_EN usages. Converge on the generalized macro: - t-beam-1w variant.h: define RADIO_FAN_EN instead of RF95_FAN_EN - SX126xInterface: drop the inline RF95_FAN_EN block now covered by the enableFan() call directly below it (avoids double-driving the pin and the PWM/digitalWrite conflict on PWM variants) All radio interfaces now drive the fan exclusively through enableFan()/disableFan().	2026-06-03 13:27:41 +02:00

Copilot Ben Meadorscopilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com>	51f56ccb4e	Fix mini-epaper-s3 build: resolve SensorLib `isBitSet` macro conflict with SparkFun MMC5983MA (#10584 ) * Initial plan * Fix SensorLib isBitSet macro conflict with SparkFun MMC5983MA library SensorLib 0.3.4 defines isBitSet as a C preprocessor macro in SensorLib.h, which conflicts with SparkFun_MMC5983MA_IO.h's class method of the same name. When both libraries are included in the same translation unit (e.g., via configuration.h → SensorRtcHelper.hpp → SensorLib chain, alongside the SparkFun MMC5983MA library in lib_deps), the macro expansion causes compile errors like 'expected unqualified-id before const'. Fix: undefine the isBitSet macro right after including SensorRtcHelper.hpp in configuration.h, so it doesn't interfere with SparkFun's class method. --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com>	2026-05-30 08:59:55 -05:00
