(SOLVED) #28044 laserRangeFinder: problems with SC-C: convert lrfBaseTest_1.spin to c-program:

nomad

hello

i have problems convert lrfBaseTest_1.spin to lrfBaseTest_1.c

on the c-source : program cant read the distance-values.
troubles with the serial-stuff
as attachments lrf-c.zip (spin + my bad c-source).
my new c-code:

//
// automatically generated by spin2cpp v3.2.0 on Sun Oct 9 16:18:15 2016
// ./spin2cpp.linux LRF_Basic.spin
//

/*
run fehler bei: range = readDec(lrf);
