Hi,

why when i connect Arduino with flash ans use print function, we need to write Serial.print(0,BYTE);
for example

Serial.print("aa);
Serial.print(0,BYTE);

if i dont use 'Serial.print(0,BYTE);' Flash will not receive anything.

Thanks

Hmmm. Are you sure flash does not recieve anything? It could be that flash stores it as a char, and then it makes sense that you can't see 0, because it is nul.

Does flash require a null terminator on strings ?

AcrionScript::String

I doubt you need to make sure it's there if it's needed. :slight_smile:
