Bramble Build

Build the bramble firmware for RP2040.

Arguments

• •$ARGUMENTS - Hardware variant: SENSOR, IRRIGATION, CONTROLLER, HUB, GENERIC, or ALL (default: ALL)

Instructions

1. •

   Parse the variant argument

   • •If $ARGUMENTS is "ALL" or empty/not provided, build all variants using HARDWARE_VARIANT=ALL
   • •If $ARGUMENTS matches a valid single variant (SENSOR, IRRIGATION, CONTROLLER, HUB, GENERIC), build only that variant
   • •The executable names are bramble_<variant> (lowercase), e.g., bramble_sensor
2. •

   Build the firmware

   All builds use the same build/ directory. CMake supports HARDWARE_VARIANT=ALL which defines all variant targets in a single configure, so -j8 parallelizes across all variants automatically.

   bash

   ~/.pico-sdk/cmake/v3.31.5/bin/cmake -B build -DHARDWARE_VARIANT=<VARIANT> 2>&1
   ~/.pico-sdk/cmake/v3.31.5/bin/cmake --build build -j8 2>&1
   

   Where <VARIANT> is one of: ALL, SENSOR, IRRIGATION, CONTROLLER, HUB, GENERIC.

   Report results

   • •On success: Report which variants built successfully and their output file locations
   • •On failure: Report which variants failed and show compiler errors
   • •For ALL builds, summarize: "X/5 variants built successfully"

Example Usage

/bramble-build           # Build ALL variants
/bramble-build ALL       # Build ALL variants
/bramble-build SENSOR    # Build only SENSOR variant
/bramble-build IRRIGATION # Build only IRRIGATION variant
