Hi

I need to initialize very large array, up to 2048 value.

The data are in this format

ARRAY [] =
0x00, 0x00, 0x00, 0x00, 0x00,
0xFE, 0xE0, 0x00, 0x00, 0x00
0xFF, 0x5C, 0x00, 0x00, 0x00,
0xFF, 0xF5, 0x08, 0x20, 0x00,
0xFF, 0x38, 0x00, 0x00, 0x00,
0xFF, 0x80, 0x00, 0x00, 0x00,

I initialized the array with the C code using this instruction
array [430] = {0x00, 0xFF ....};
but without success.

The compilation does not report errors, but the array is not initialized

any suggestions?

Thanks in advance

What is your target device? The Lookup component is probably what you are looking for.

Hi Kersing

my target devide is dsp, specifically the ram.
I need to perform several configuration writes, but for the two larger ones, which are the program and the parameters I need two different arrays.

By checking the forum I saw that they were postponed for the lookuptable but I can not figure out how to make it work.

Data from these arrays must be transmitted via i2c.

I have already tried to communicate a single byte with the dsp and it works correctly, as I have tested the sending of a small array and that has worked too.

How do I pass the values ​​of this lookup table to the i2c macro?

For target device I mean which controller do you want to use? PIC 8 bit, PIC 16 bit, ARM, Atmel?

I currently use a pic32 mx470f512h

Hello everyone

I update you about the initialization of a large array.

I was able , through the use a lookup table, to initialize an array and to program the external memory!
