I use uno and lcd shield, why this code messes up my lcd output? With Serial print it gets stuck. With no print in program it works fine(ir signals received/sent correctly).
#define rec_memory 10
int rec_ind = 0;
// Storage for the recorded code
int codeType[rec_memory]={-1}; // The type of code
unsigned long codeValue[rec_memory]; // The code value if not raw
//unsigned int rawCodes[rec_memory][RAWBUF]; // The durations if raw
int codeLen[rec_memory]; // The length of the code
int toggle[rec_memory]={0}; // The RC5/6 toggle state
typedef int rawCodesDef[RAWBUF];
struct RawCodes {
rawCodesDef x;
};
RawCodes rawCodes[rec_memory];
////// somewhere in code /////
RawCodes tmpRawCodes;
for(int i=0; i<RAWBUF;i++){
// tmp_rawCodes[i] = 1;
tmpRawCodes.x[i] = i+2;
}
// for(int i=0; i<10;i++){
// rawCodes[1][i] = tmp_rawCodes[i];
//}
rawCodes[1] = tmpRawCodes; // problem code <<<<<<<<<
in my debugging i only lcd.print "hello +time()"
with "//rawCodes[1] = tmpRawCodes;" commented out i get " hello 1" , "hello 2" etc
with " rawCodes[1] = tmpRawCodes;"
i get "hello 1$%@...", "hello 2%5*" etc

}
and using your code i get
sketch_jan17b:89: error: cannot convert 'RawCodes' to 'const void*' for argument '2' to 'void* memcpy(void*, const void*, size_t)'
