Hello all,

Is there a limitation in the number of values to write to internal EEPROM at once ?

I have 250 values to write

0, 0, 0, 0, 0, 1, 1, 1, 2, 2, 3, 3, 4, 4, 5, 6, 7, 8, 8, 9, 10, 11, 13, 14, 15, 16, 18, 19, 20, 22, 23, 25, 27, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 53, 55, 57, 60, 62, 65, 68, 70, 73, 76, 79, 82, 85, 88, 91, 94, 97, 100, 103, 107, 110, 113, 117, 120, 124, 127, 131, 135, 139, 142, 146, 150, 154, 158, 162, 167, 171, 175, 179, 184, 188, 192, 197, 201, 206, 211, 215, 220, 225, 230, 235, 240, 245, 250, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 0, 0, 0, 0, 0, 8, 31, 100, 96, 100, 0, 0, 0, 0, 0, 4, 5, 57, 100, 87, 0, 8, 15, 20, 25, 35, 5, 1, 1, 85, 100, 95, 100, 81, 0, 0, 0, 0, 0, 0, 87, 100, 57, 5, 16, 13, 5, 0, 0, 0, 85, 1, 1, 5, 48, 38, 28, 17, 8, 0

But after compiling only a few (and not the good one) are written.

Here is a little program I made to test

Hello Bernard,

Looking at the C code these are the values that are being set.

Code: Select all

#ifdef MX_CAL_PIC
#pragma DATA _EEPROM, 0,0,0,0,0,1,1,1,2,2,3,3,4,4,5,6,7,8,8,9,10,11,13,14,15,16,18
#endif

Which is nothing like what it should be. I'll have a dig into the component now and see if I can work out why this is failing.

Hello,

I think I have now fixed the problem, it seemed the EEPROM component had a cap on how many characters were in the initialiser string so I have now upped this to 1000 characters which seems to be making it work through to the C correctly.
