Debit 2061 Flow Sensor

Pulse-based flow sensor driver with EXTI increment and periodic rate computation.

Functions

void flow_sensor_init(FlowSensor_t* s, uint32_t pulses_per_litre, uint8_t port)

Initializes the pulse counter and scaling.

void debit_sensor_update(FlowSensor_t* s, uint32_t current_tick)

Computes flow in ml/s based on pulse count and elapsed time.

void flow_sensor_EXTI_handler(FlowSensor_t* s)

ISR callback that increments the pulse counter.

uint16_t debit_sensor_decode(uint8_t high_byte, uint8_t low_byte)

Combines two bytes into a raw value.

Usage

#include "debit_2061.h"

static FlowSensor_t flow = {0};

void flow_init(void) {
    flow_sensor_init(&flow, 450U, 0);
}

void flow_exti_isr(void) {
    flow_sensor_EXTI_handler(&flow);
}

void flow_task(uint32_t now) {
    debit_sensor_update(&flow, now);
}

WARNING

flow_sensor_EXTI_handler is intended for ISR context; keep it minimal.
