Question regarding int16 arrays??

[arunb]

Hi,

MCU: 16F877A
Compiler: PCM 3.228

I have the following declaration

int16 nVariable[18],p[8],nReturn;

Is this OK

nVariable[p[0]]=nReturn;

Or do I have to do this

nVariable[make8(p[0],0]=nReturn;

I find that when I use the first method, the value stored in nVariable[0] array is lost, when I load nVariable[1] with some data.

The program compiles OK, the RAM is 78-91 % and does not generate any errors, is it possible that the program goes haywire in the mcu ?

thanks

Both methods should work, but the second method with the make8() looks clumsy, if the array p only is to contain 8 bit data than declare it int8 instead of int16.

I couldn't reproduce your error. As a regular poster on this forum you should know a small but complete program demonstrating your problem will give you better and faster responses, until then I'm not going to spend more time into this
