Flash Library Help Mistake

[JimKueneman]

Reading the flash library docs was confusing me for the dsPIC33

procedure FLASH_Write(address : longint; var data_ : array[64] of word);

Fills one writeable block of Flash memory (64 instructions, 128 addresses, 192 bytes) in the "regular" mode. Addresses and data are being mapped 1-on-1. This also means that 3rd byte of each program location remains unused.

That made no sense as an instruction is 2 words wide and it says 64 instructions were passed in the array...

In the compiler if you check code completion it says

procedure FLASH_Write(address : longint; var data_ : array[128] of word);

That makes more sense.

Hi,

The routine prototype that you are referring to:

Code: Select all

procedure FLASH_Write(address : longint; var data_ : array[128] of word);

is used for PIC24EP and dsPIC33EP MCUs, for the dsPIC33 it is :

Code: Select all

procedure FLASH_Write(address : longint; var  data_ : array[64] of word); 

Regards,
Filip.

Sorry I am using the dsPIC33EP that is why I needed the 128. A blurb about that different in the help would be useful.

Hi,

Yes, I agree it would be good if this is documented.
