Hi,
Jal does not support multi-dimensional arrays.
Watch your math, is 8+14*i this line correct? Maybe it should be 8+(14*i)
or (8+14)*i
On this line, your array is a byte, and can't fit what you are putting in
it. You are trying to put 2 ASCII characters into one byte.
const byte f0 [] = "f0"
Maybe you want:
const byte f0[2] = {"f","0"}
or:
const byte f0 = 0xF0
Your compile output will be giving you warnings. You should be able to
compile your program with no warnings. If there is a warning your not sure
about, please ask.
Matt.
