#175000 - unsigned int is not the size of the unsigned int* pointer Responding to: ???'s previous message |
Isn't it time for you to study basic C?
char EEPROM_Read(unsigned int *address) * means it's a pointer. unsigned int is not (!) the size of the pointer. It is the type of the data the pointer points at. So having a pointer to unsigned int, and using this pointer to pick up an unsigned int, and store into a char, does show that you have problems understanding basic data types. Most EEPROM implementations works with 8-bit data, so they pick up or writes one byte at a time. You then potentially write helper functions that reads and writes larger-sized variables. |

| You have to choose your API | 01/01/70 00:00 | |
| Already did all that | 01/01/70 00:00 | |
| char vs int | 01/01/70 00:00 | |
| I gave you a function | 01/01/70 00:00 | |
| Still no luck | 01/01/70 00:00 | |

| Why not use the function I gave you. | 01/01/70 00:00 | |
