Re: Bitx40 Pavel's blend sketch updated (the Allard's folk one with S-Meter, TX-meter, AGC)

Hi Jonathan:

The problem stems from the definition of the model[] array. The new parser tightens things up a bit, as illustrated in the following program:

void setup() {
?
? const char *model[] = {" LSB", " USB", " CWL", " CWU"}; ? ? // Use this line, no warning
?
? // char *model[] = {" LSB", " USB", " CWL", " CWU"}; ? ? ? ?// Use this line, deprecated warning

? char test[4];

? Serial.begin(9600);
??
? strcpy(test, model[1]);
? Serial.println(test);?
}

void loop() {
}

The problem is caused by not using the const type qualifier when you define a variable that has an initializer list like the code does above. Try running the sample program toggling the two definitions for model[]. Given the way I've used the array (in strcpy()), it's ok to ignore the warning.
