I was going to try and help you out so I did some poking around with the SX28 chip. File attached.


If any of the statements are incorrect below please correct me, it is what I understand it now and may not be correct.

The SXB Basic compiler uses memory variables $00 thru $0C for its own internal use.

When you define your firat variable it uses the next available memory locations, $0D $0E, $0F ... up to $1F

When you use the BANK command to switch between the 8 banks of memory you can use only memory locations $10 thru $1F in each of the banks bank1 thru Bank7

So those 3 bytes $0D, $0E, $0F in bank 0 throw you off when bank switching. The file attached I define v1, v2, and v3 as the first 3 byte variable names and then x1 .. x16 as 16 more variables.

Then I can switch banks from 0 to 7 to get 64 bytes of variable space.

One problem though, The compiler on pass 2 seems to have a problem aND GIVES A WARNING, the code runs in the debugger though so perhaps someone can tell us why it is giving a warning. Funny thing the x1=255 thru x4=255 code gives the warnings about current bank, if i comment out x1 thru x4 then it gives warnings on the next 4 code lines x5=255 thru x8=255 maby someone knows why.


So warnings aside you could set up banks of 8 LED variables, use groups of 2 for your number of key hits to compare too and the other one for number of key hits current. Then switch banks and compare the next set of 8.
