Data Tables

[keytapper]

I'm trying to understand some inside of the compiler. I was expecting to read flash as it's possible to read a RAM position.

Dim timerValue As Byte                       ' Start time for period measurement
Dim tableSample as Flash8 = { 127,134,29,83,51,242,148,177,126,177,
                             148,242,51,83,29,134,127,121,225,172,
                             204,13,107,77,129,77,107,13,204,172,225,121}

timerValue = CRead AddressOf(tableSample)+5  ' this a bit cumbersome, less elegant

' maybe I may try to make a $define that will translate the above method

timerValue = tableSample[5]                  ' now it causes an error
One more question:
Do the enhanced MCUs of the Midrange family store one byte for every byte defined as flash or code8?

[trastikata]

MyResult = Cread8,16,24,32 Byte_Table[Offset]

 

[keytapper]

MyResult = Cread8,16,24,32 Byte_Table[Offset]

Is a MCU type dependency?
I was try with 12F1840 MCU, perhaps 18F family doesn't make glitches.
On the other hand is it simple to make a macro?

$define read_table(x,y) (Cread8{16|24|32} addressOf(x)+y)It probably fail because x is the variable name

[flosigud]

timerValue = CRead8 tableSample[offset]
If you test code in a meta macro and it fails the error messages, if any, won't be meaningful.

[keytapper]

timerValue = CRead8 tableSample[offset]

This remain within the source made, the variable is tied up to its name.
I didn't try the mentioned macro, I presume just a silly thought, because I suppose we cannot pass in a variable name.
