byte format #1

Closed hmronline closed 4 years ago

Could it be possible to add byte or uint8_t to the supported value type list?

Thanks, Hernán.-

Hi, I'll add the unsigned specifiers for 8/16/32 bit integers soon.

Btw it's nice to see that someone is using the library.

It's possible now to use unsigned types (from version 0.1.2). I couldn't think of any characters that would be intuitive format specifiers for 4 different existing types ("c", "d", "L", "x"), so I thought that the existing ones can be preceeded with "u" instead, like: "uc" - uint8_t "ud" - uint16_t "uL" - uint32_t "ux" - uint32_t (using hexadecimal as input)

  const char * csv_str = "bytes,words,dwords,dwords_from_hex\n"
                         "255,65535,4294967295,FFFFFFFF\n"
                         "254,65534,4294967294,FFFFFFFE\n";

  CSV_Parser cp(/*format*/ "ucuduLux");

I added full example here: https://github.com/michalmonday/CSV-Parser-for-Arduino/blob/master/examples/unsigned_values/unsigned_values.ino

That's great, it seems it's working as expected. Thank you!
