I have created a functional base64 encoding method for the ybox.

It’s not ideal as it requires the programmer to declare an output array large enough to hold the result of the encoding procedure. I tried everything I could think of to avoid this by using the size of the input string (strsize(in_ptr)*(4/3)) to store the output, but I couldn’t get it.

Download the updated base64.spin.

Sample usage:

CON
_clkmode = xtal1 + pll16x
_xinfreq = 5_000_000

OBJ
text : "TV_Text"
b64  : "base64"

VAR
byte outstring[25]

PUB start | i
text.start(12)

b64.encode(string("admin:admin"), @outstring)
text.str(@outstring)
text.out(13)

b64.encode(string("admin:password"), @outstring)
text.str(@outstring)
text.out(13)

b64.encode(string("Die SPIN Die!"), @outstring)
text.str(@outstring)
text.out(13)

b64.encode(string("meh"), @outstring)
text.str(@outstring)

repeat

And a sample image from the above code:

If anyone has any tips that can help get rid of the need to declare the output variable’s size, please let me know. Tim
