I have installed an IR receiver on the "black" DAC+ card.

Okay, solid basis. So I thought I would use the code provided to manipulate the volume.
I have cloned the code into a dir "tools". If i do sudo IQ_ir& it fails "sudo: IQ_ir: command not found"
That’ll be linux. the current directory is not on the path. so try: sudo ./IQ_ir& I wasn't surprised because in alsamixer the volume control is shown as "Digital" rather than PCM. So I changed IQ_ir.c and IQSetupMix.c to use "Digital". I then compiled IQSetupMix.c using the instructions in the file. Compiled clean. Then compiled IQ_ir.c which compiles with warnings (compiled these with the cli in issue 4 that discusses compiling) gcc -include /usr/include/lirc/lirc_client.h -o IQ_ir IQ_ir.c -llirc_client -lasound -lwiringPi IQ_ir.c:36:0: warning: "TRUE" redefined
define TRUE 1
^ In file included from IQ_ir.c:17:0: /usr/include/wiringPi.h:32:0: note: this is the location of the previous definition
define TRUE (1==1)

define FALSE 0
^ In file included from IQ_ir.c:17:0: /usr/include/wiringPi.h:33:0: note: this is the location of the previous definition
define FALSE (!TRUE)

So that’s just because we’ve both used the variables called TRUE and FALSE, so the compiler thinks they are being redefined. I’ve just changed the code to use IQTRUE and IQFALSE. I’ve also changed the mixer to Digital and bumped the version number.
If I sudo IQ_ir& i get the same failure as above
Frankly I am pretty lost. So I am wondering
Any idea regarding how I can proceed to get IQ_ir.c to work
Try the latest version. Change DEBUG_PRINT den to below.
define DEBUG_PRINT 1
compile and run without the & (which puts the task in the background) sudo ./IQ_rot
then you should see any error messages etc coming out.
• or • Can you advise whether I can use python to do the same thing - finding it relatively easy to understand compared to C.
Python, probably. not tried it. I jumped form Cobol to C myself. Python is a black art. :-)
Thank You in advance.
