WebJul 30, 2012 · When Serial data is transmitted to an Arduino, it is sent one byte at a time. Even though you might type “123” in the Serial Monitor, that’s not quite what is sent. Instead the bytes “1” then “2” then “3” are sent. Once received into a buffer on the Arduino, these individual bytes need to be reassembled into something useful. WebThat will give you 2-byte pointers (const char *) which will not be large enough to index into 89400 characters. So you need to have an array of 4-byte pointers like this: uint_farptr_t …
