Hallo Leute,

sieht jemand den Fehler in meinen Code? Ich versuche den SNR der Slave-Chibi auszulesen. Mit Java gehts unter C zeigt er mit 0.00000

#include <stdio.h>

#include "ip_connection.h"
#include "brick_master.h"

#define HOST "XXX.XXX.XXX.XXX"
#define PORT 4223
#define UID "XXXXXXXXXXX" // Change to your UID

int main() {
        // Create IP connection to brickd
        IPConnection ipcon;
        if(ipcon_create(&ipcon, HOST, PORT) < 0) {
                fprintf(stderr, "Could not create connection\n");
                exit(1);
        }

        // Create device object
        Master master;
        master_create(&master, UID);

        // Add device to IP connection
        if(ipcon_add_device(&ipcon, &master) < 0) {
                fprintf(stderr, "Could not connect to Brick\n");
                exit(1);
        }
        // Don't use device before it is added to a connection

        uint16_t voltage;
        master_get_stack_voltage(&master, &voltage);
        uint16_t current;
        master_get_stack_current(&master, &current);

        printf("Stack Voltage: %f V\n", voltage/1000.0);
        printf("Stack Current: %f V\n", current/1000.0);

        // Get SNR
        uint8_t snr;
        master_get_chibi_signal_strength(&master, &snr);
        printf("%f", snr);
}

 

Vielleicht ist es einfach nur wieder "Betriebsblindheit"

 

Edit: Ich verwende die aktuellen Bindings.

Probier mal %d anstatt %f im printf

Danke hat geholfen...für solche Dinge hasse ich C
