- Added devicetree overlay for VND7050AJ with GPIO and ADC configuration - Created custom devicetree binding for VND7050AJ valve controller - Implemented valve_get_supply_voltage() function with proper pin control: - RST=HIGH to enable VND7050AJ - S0=1, S1=1 for supply voltage sensing mode - SEN=1 to enable MULTISENSE output - ADC reading on PA0 (ADC1_IN1) with 12-bit resolution - Fixed supply voltage calculation (VCC/8 per datasheet) - Added comprehensive debug logging for all steps - Tested and verified ADC functionality - Current reading: 5.1V (may be limited by hardware power supply) Files modified: - software/lib/valve/valve.c: Main implementation - software/apps/slave_node/boards/weact_stm32g431_core.overlay: DT config - software/apps/slave_node/dts/bindings/vnd7050aj-valve-controller.yaml: DT binding - software/apps/slave_node/src/main.c: Test code - software/apps/slave_node/prj.conf: ADC driver enablement
