Error C 212 Keil

An error is generated when a memory-specific pointer is assigned to another memory-specific pointer to a different memory area. When parameters passed to a function via a function pointer will not fit into registers, the compiler cannot determine where in memory to place the parameters since the function is not Important information This site uses cookies to store information on your computer.

HTH! Function pointers, for all practical purposes is a "convenience feature". Please review our Privacy Policy to learn more about our collection, use and transfers of your data. Discover More Please review our Privacy Policy to learn more about our collection, use and transfers of your data.

If function pointers really are essential to your application, then you should probably not be using an 8051 - at the very least, you need to study the issues very carefully!

For example: void (*CallBack1) (void *, unsigned char); void (*CallBack2) (void xdata *, void xdata *); void (*CallBack3) (char, char, char); void (*CallBack4) (char, char, int); unsigned char c, d, e, Please review our Privacy Policy to learn more about our collection, use and transfers of your data.

This technique generates very efficient code but limits the parameters that can be passed to indirectly called functions.
