Hi,

Our project use S12ZVCA19. We need create an array to save 30000 strings (each string =10 characters).

Is it can work? How to make sure the free space in memory?

Best Regards,

Aaron

Hi, Daniel,

uint32_t      array[30000];

Can I use that define in S12ZVCA19?

BTW, I have define a lot of variable, how to check the free space of variable?

Best Regard,

Aaron

Hi Aaron,

The S12ZVCA19 MCU has 12KB of SRAM.

You can't use a 120KB variable.

Please check the linker file and the map file.

Hi Aaron,

I'm afraid you can't store 300KB on a 192KB Flash.
