Questions:

• ihouses@iespana.es asks:

  Hello! I have a problema with the ht-pic compiler. I want to create some arrays in RAM for ex. unsigned char array1[40]; unsigned char array2[40]; the problem is that the compiler only can acced to the bank0 of the pic RAM memory, and i can´t use all RAM of the pic. What i have to do? Thanks!

Comments:

• I had the same problem, then i made the array global at the beginning of the programm and all was working.
• i am looking for sample code of i2c on GPIO in pic18f452

I have also been struggling with bank switching in HiTech Pic C. The only example I found (in the HiTech FAQ) claims you can qualify the location of any array declaration thusly:

bank1 char arrayName[40];

But I've had no success. Compiler gives a warning "qualifier not needed" and still uses Bank 0. I'm sure this can be done. Maybe it's too obvious for anyone to talk about - but ihouses up there is not the only one missing the secret.
