RF12 module need to convert some C to Basic

[davewanna]

Skimask,

Thankyou for doing that... From the little bit of C that I have learnt in the last 24 hours, that looks good.

I did try nSEL last night with a couple of code attempts, but I did not try it consistantly.

I did also try to use the SSP last night for a short period. No luck yet, but I didn't expect it to be easy, I haven't used the SSP yet.

I am off to work now, but will try again later today.


Thanks for the assistance.

It could be a timing issue. No time to check now. If anyone could?

I am just getting started on this again tonight...

I the example from Skimask above, the variable CMD is I assume an array of 16 bits? so I should declare..

CMD  VAR  bit[16]

Am I correct?


My next question is how do I get my word variable into series of 16 bits?

dout = $D0F7

for n = 16 to 0 step -1
  CMD[n] = %dout.15
  dout << 1
next n

Keep in mind I am almost certain that the above example will not work... It's just to show that I am trying, not just asking everyone else to make my project for me...

For this CMD[n] = %dout.15 try as:

CMD.0[n] = %dout.15

My current attempt is....

cmd             var byte[15]
dout = $C0F7

...

lcdout $fe,$C0," "
for n = 16 to 1 step -1
  CMD.0[n] = dout.15
  dout = dout << 1
  lcdout $fe,14,bin dout.15
next n

This results in ... 1000000111101110 ... and I want ... 1100000011110111 ...

i.e. It has chopped the 1 off the start, and added a 0 on the end...

[Ioannis]

Try this

for n = 15 to 0 step -1

I just realised what I did...

dout = dout << 1
lcdout $fe,14,bin dout.15

I was displaying the dout bit after it had shifted... Stupid me.. I swapped those 2 lines, and I know I am giving the right string of bits to the array...
I'm trying to display the array to see if all those bits went in.. Something is not right tho.

n		        VAR	BYTE
nn		        VAR	BYTE
cmd                            VAR            BYTE[15]
...

lcdout $fe,$C0," "
for n = 15 to 0 step -1
  CMD.0[n] = dout.15
  lcdout $fe,14,bin dout.15
  dout = dout << 1
next n

lcdout $fe,$d4," "
for nn = 0 to 15
  lcdout $fe,$14,cmd.0[nn]
next nn

This last bit where I try to display the cmd array just gives me garbage characters.
