Re: SDRPLAY linux commandline tools?

i am not sure about the 16bit output if it is valid,when i play it it sounds too fast....... like played double speed.... i changed: for (i=0; i < samplesPerPacket; i++) { buffer[j++] = ibuf[i]; buffer[j++] = qbuf[i]; } and short *buffer; and buffer = malloc(DEFAULT_BUF_LENGTH * sizeof(short)); is t...

Re: SDRPLAY linux commandline tools?

you have to compile play_sdr.c first: Makefile: CFLAGS?=-O2 -g -Wall -W LDLIBS+= -lpthread -lm -lmirsdrapi-rsp CC?=gcc PROGNAME=play_sdr all: play_sdr %.o: %.c $(CC) $(CFLAGS) -c $< play_sdr: play_sdr.o $(CC) -g -o play_sdr play_sdr.o $(LDFLAGS) $(LDLIBS) clean: rm -f *.o play_sdr copypaste this cod...

Re: SDRPLAY linux commandline tools?

@sdrplay, all functions on the rtl_sdr libary are demending on this: rtlsdr_read_async(dev, rtlsdr_callback, (void *)(NULL), DEFAULT_ASYNC_BUF_NUMBER, DEFAULT_BUF_LENGTH); please let me know how i can change it to use the callback function, in playsdr you are not using as you coded the file output d...

Re: SDRPLAY linux commandline tools?

well, i do not see that the rsp is initializing....

do a sudo cp play_sdr /usr/bin

and give it a try again.

if not working try to

play_sdr -s 2400000 -f 89.3 -g 50 -

if working you should see a lot of ASCII in the display which means it works but i think the above should to its job....

Re: SDRPLAY linux commandline tools?

@IW2DHW,

try this one:

http://wikisend.com/download/380816/rawIQ

rename it to play_sdr and give it a try - compiled with ubuntu 14.04.1

i guess the is no need for change in code as it uses rtl_sdr only:

"rtl_sdr -s 2400000 -f `python -c "print int($1*1e6)"` -g $GAIN -"

regards
