Walkthrough

A new preprocessor macro, USE_MAX7456, has been added to the configs/HELLBENDER_0001/config.h configuration header file. This macro is defined immediately after the existing MAX7456_SPI_CS_PIN definition, with no other modifications to the file.

Learning: In Betaflight configuration files, USE_OSD_HD and USE_MAX7456 are for different OSD systems: USE_MAX7456 enables the MAX7456 analog OSD chip, while USE_OSD_HD enables HD/digital OSD via MSP. MSP_DISPLAYPORT_UART should be guarded by USE_OSD_HD, not USE_MAX7456, as they serve different OSD implementations.

Learning: In Betaflight configuration files, feature enablement macros like USE_MAG are build options that can be controlled at compile time, while hardware instance definitions like MAG_I2C_INSTANCE are predefined in board configurations to assist with hardware mapping when those features are enabled at build time.

Learning: The DEFAULT_GYRO_ENABLED macro with both gyros enabled (GYRO_MASK(0) | GYRO_MASK(1)) should only be added to board configurations that have DEFAULT_GYRO_TO_USE set to GYRO_CONFIG_USE_GYRO_BOTH. Boards without this setting should only get the GYRO_COUNT definition to specify the number of available gyros.

Learning: In Betaflight configurations, when a target name suggests dual IMUs (like JHEF7DUAL) but specific hardware variants only have one gyro available, the preferred solution is to use DEFAULT_GYRO_TO_USE macro to specify which gyro to use by default rather than pruning gyro defines or creating redundant configurations. This approach maintains compatibility when the same target is used by multiple hardware variants from the same manufacturer.

Learning: The presence of GYRO_2_SPI_INSTANCE definition in a board config does not necessarily mean the board uses dual gyros. Some boards have GYRO_2_SPI_INSTANCE defined but it's not actually used, so they should not receive GYRO_COUNT or other dual-gyro related definitions. Only boards that actually utilize dual gyros should get these definitions.

Learning: In Betaflight configurations, SDCARD_CS_PIN and FLASH_CS_PIN can share the same GPIO pin because Betaflight uses either flash or sdcard storage, not both simultaneously. This is a mutually exclusive design where only one storage method is active at a time, so shared CS pin assignments are intentional and do not cause conflicts.

Learning: The JHEF405PRO board does not actually use dual gyros despite having GYRO_2_SPI_INSTANCE defined in its configuration. It should not receive GYRO_COUNT or other dual-gyro related definitions since only the first gyro is supported.

Learning: In STM32F405-based flight controller configurations, timer pin mappings must be carefully analyzed for DMA stream conflicts, especially between motor timers, LED strip timers, and SPI DMA assignments. Changes to TIMER_PIN_MAPPING should include verification that all required peripherals (motors, LED strip, blackbox SPI) can coexist without DMA conflicts.

56-56: LGTM! Proper enablement of MAX7456 analog OSD support.

The addition correctly enables MAX7456 functionality with the necessary hardware definitions already in place (SPI instance on line 33 and CS pin on line 55). This follows Betaflight's pattern of separating feature enablement macros from hardware configuration definitions.
