HifiBerry DAC+ und SI4703 radio modul

[brager]

Ich habe genau das selbe Problem :/
@eRRoXxX  habt ihr es hinbekommen?

ich bin der Anleitung https://tutorials-raspberrypi.de/tag/si470x/ gefolgt.

Code:

# For more options and information see
# http://www.raspberrypi.org/documentation/configuration/config-txt.md
# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=1
hdmi_mode=19

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

# Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2s=on

# Uncomment this to enable the lirc-rpi module
#dtoverlay=lirc-rpi

# Additional overlays and parameters are documented /boot/overlays/README

# Enable audio (loads snd_bcm2835)
dtparam=audio=on
gpu_mem=256
dtparam=i2c_arm=on
disable_splash=0

1. RASPBIAN JESSIE WITH PIXEL
Image with PIXEL desktop based on Debian Jessie
Version:February 2017
Release date:2017-02-16
Kernel version:4.4
installiert

2. Aktualisiert .. upgradet .. Carpi installiert
(Carpi: https://christian-brauweiler.de/howto/ca...-anleitung)

3. unter raspi-config i2c und spi aktiviert

leider noch kein erfolg
4. https://tutorials-raspberrypi.de/raspber...io-car-pc/ durchgeführt
kleine Anpassungen auch bei der Pinbelegung im i2c-init gemacht.

5. Kompiliert und ausgefügt

sudo ./i2c-init

mit den Werten:

Code:

/* i2c-init.c */
#include <wiringPi.h>

int main() {
   int resetPin = 4; // GPIO23
   int sdaPin = 2; // GPIO0

   /* Setup GPIO access in BCM mode */
   wiringPiSetupGpio();

   /* Set pins as output */
   pinMode(resetPin, OUTPUT);
   pinMode(sdaPin, OUTPUT);

   /* A low SDA indicates a 2-wire interface */
   digitalWrite(sdaPin, LOW);
   /* Put chip into reset */
   digitalWrite(resetPin, LOW);
   /* 1ms delay to allow pins to settle */
   delay(1);
   /* Bring chip out of reset with SDIO set low
   and SEN pulled high (with pull-up resistor) */
   digitalWrite(resetPin, HIGH);

   return 0;
}
